280 ideas
22115 | Wise people should contemplate and discuss the truth, and fight against falsehood [Aquinas] |
Full Idea: The role of the wise person is to meditate on the truth, especially the truth regarding the first principle, and to discuss it with others, but also to fight against the falsity that is its contrary. | |
From: Thomas Aquinas (Summa Contra Gentiles [1268], I.1.6), quoted by Kretzmann/Stump - Aquinas, Thomas 14 | |
A reaction: So nice to hear someone (from no matter how long ago) saying that wisdom is concerned with truth. If you lose your grip on truth (which many thinkers seem to have done) you must also abandon wisdom. Then fools rule. |
12644 | Who cares what 'philosophy' is? Most pre-1950 thought doesn't now count as philosophy [Fodor] |
Full Idea: Who cares what gets called 'philosophy'? It's my impression that most of what happened in philosophy before 1950 wouldn't qualify according to the present usage. | |
From: Jerry A. Fodor (LOT 2 [2008], Ch.3.5) | |
A reaction: A rather breath-taking remark. Fodor is, of course, a devotee of David Hume, and of Descartes, but he never seems to refer to Greeks at all. Personally I presume that if you aren't doing what Plato and Aristotle were interested in, it ain't philosophy. |
22101 | Philosophy aims to know the truth about the way things are [Aquinas] |
Full Idea: The study of philosophy has as its purpose to know not what people have thought, but rather the truth about the way things are. | |
From: Thomas Aquinas (Sententia on 'De Caelo' [1268], I.22.228), quoted by Kretzmann/Stump - Aquinas, Thomas 05 | |
A reaction: I agree with this deeply unfashionable opinion. Of course, modern investigations must be more sensitive to biases built into language, culture and conceptual schemes. But I am one of those sad old folks who still think truths can be stated. |
12633 | Definitions often give necessary but not sufficient conditions for an extension [Fodor] |
Full Idea: Attempts to define a term frequently elicit necessary but not sufficient conditions for membership of its extension. This is called the 'X problem', as in 'kill' means 'cause to die' plus X. | |
From: Jerry A. Fodor (LOT 2 [2008], Ch.2.1 n3) | |
A reaction: Fodor is one of the great sceptics about definition. I just don't see why we have to have totally successful definitions before we can accept the process as a worthwhile endeavour. |
2474 | It seems likely that analysis of concepts is impossible, but justification can survive without it [Fodor] |
Full Idea: Lots of philosophers fear that if concepts don't have analyses, justification breaks down. My own guess is that concepts don't have analyses and that justification will survive all the same. | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 3 n2) |
2481 | Despite all the efforts of philosophers, nothing can ever be reduced to anything [Fodor] |
Full Idea: The general truth is that nothing ever reduces to anything, however hard philosophers may try. | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 6) |
1848 | We are coerced into assent to a truth by reason's violence [Aquinas] |
Full Idea: We are coerced into assent to a truth by reason's violence. | |
From: Thomas Aquinas (Quaestiones Disputatae de Malo [1271], Q6.10) |
1858 | The mind is compelled by necessary truths, but not by contingent truths [Aquinas] |
Full Idea: Mind is compelled by necessary truths that can't be regarded as false, but not by contingent ones that might be false. | |
From: Thomas Aquinas (Quaestiones Disputatae de Malo [1271], Q6.h to 12) |
2463 | A standard naturalist view is realist, externalist, and computationalist, and believes in rationality [Fodor] |
Full Idea: There seems to be an emerging naturalist consensus that is Realist in ontology and epistemology, externalist in semantics, and computationalist in cognitive psychology, which nicely allows us to retain our understanding of ourselves as rational creatures. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §4) |
2505 | Turing invented the idea of mechanical rationality (just based on syntax) [Fodor] |
Full Idea: The most important thing that has happened in cognitive science was Turing's invention of the notion of mechanical rationality (because some inferences are rational in virtue of the syntax of their sentences). | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch.17) |
21267 | Supposing many principles is superfluous if a few will do it [Aquinas] |
Full Idea: It is superfluous to suppose that what can be accounted for by a few principles has been produced by many. | |
From: Thomas Aquinas (Summa Theologicae [1265], Ia,Q02,Art3,Ob2) | |
A reaction: Notice that this is 'superfluous' rather than 'wrong'. But ten people can lift a piano which could have been lifted by eight. Note that this is 150 years before Ockham. |
22102 | Arguing with opponents uncovers truths, and restrains falsehoods [Aquinas] |
Full Idea: There is no better way of uncovering the truth and keeping falsity in check than by arguing with people who disagree with you. | |
From: Thomas Aquinas (On the spiritual perfection of life [1268], 26), quoted by Kretzmann/Stump - Aquinas, Thomas 05 | |
A reaction: Not the sort of attitude you associate with medieval scholastics, who are presumed to be dogmatists. How many modern philosophers actually have the courage to follow this advice? |
11197 | The definitions expressing identity are used to sort things [Aquinas] |
Full Idea: What sorts things into their proper genus and species are the definitions that express what they are. | |
From: Thomas Aquinas (De Ente et Essentia (Being and Essence) [1267], p.92) | |
A reaction: This is straight from Aristotle, though Aristotle's view is a little more complex, I think. If the definitions 'express what they are', then definitions seem to specify the essence. |
13070 | If definitions must be general, and general terms can't individuate, then Socrates can't be defined [Aquinas, by Cover/O'Leary-Hawthorne] |
Full Idea: Socrates has no definition if definitions by their nature must be in purely general terms, and if no purely general terms can succeed in uniquely singling out this signated matter. | |
From: report of Thomas Aquinas (De Ente et Essentia (Being and Essence) [1267], 23) by Cover,J/O'Leary-Hawthorne,J - Substance and Individuation in Leibniz 1.1.2 | |
A reaction: There seem to be two models. That general terms actually individuate the matter of Socrates, or that they cross-reference to (so to speak) define Socrates 'by elimination', as the only individual that fits. But the latter is a poor definition. |
12619 | We have no successful definitions, because they all use indefinable words [Fodor] |
Full Idea: There are practically no defensible examples of definitions; for all the examples we've got, practically all the words (/concepts) are undefinable. | |
From: Jerry A. Fodor (Concepts:where cogn.science went wrong [1998], Ch.3) | |
A reaction: I don't think a definition has to be defined all the way down. Aristotle is perfectly happy if you can get a concept you don't understand down to concepts you do. Understanding is the test, not further definitions. |
2470 | Transcendental arguments move from knowing Q to knowing P because it depends on Q [Fodor] |
Full Idea: Transcendental arguments ran: "If it weren't that P, we couldn't know (now 'say' or 'think' or 'judge') that Q; and we do know (now…) that Q; therefore P". Old and new arguments tend to be equally unconvincing, because of their empiricist preconceptions. | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 3) |
23176 | Truth is universal, but knowledge of it is not [Aquinas] |
Full Idea: The truth is the same for all, but is not equally known to all. | |
From: Thomas Aquinas (Summa Theologicae [1265], I-II Q94 4) | |
A reaction: Amazing how many modern thinkers fail to grasp this simple distinction. However, the truth is not quite the same for all if diverse persons are expressing a single truth with different concepts and languages. The word 'facts' is helpful here. |
20621 | Types of lying: Speak lies, intend lies, intend deception, aim at deceptive goal? [Aquinas, by Tuckness/Wolf] |
Full Idea: Lying can involve (1) speaking false words, (2) the intention to speak false words, (3) the intention of bringing about deception, and (4) the ultimate goal of one's deception. | |
From: report of Thomas Aquinas (Summa Theologicae [1265], Q110) by Tuckness,A/Wolf,C - This is Political Philosophy 10 'Lying' | |
A reaction: It's a start, but much more is needed to clarify lying. Irony is an obvious problem with (1). |
1852 | For the mind Good is one truth among many, and Truth is one good among many [Aquinas] |
Full Idea: Good itself as taken in by mind is one truth among others, and truth itself as goal of mind's activity is one good among others. | |
From: Thomas Aquinas (Quaestiones Disputatae de Malo [1271], Q6.reply) |
2435 | Psychology has to include the idea that mental processes are typically truth-preserving [Fodor] |
Full Idea: A psychology that can't make sense of such facts as that mental processes are typically truth-preserving is ipso facto dead in the water. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §1.3) |
21248 | If the existence of truth is denied, the 'Truth does not exist' must be true! [Aquinas] |
Full Idea: Whoever denies the existence of truth grants that truth does not exist: and if truth does not exist, then the proposition 'Truth does not exist' is true: and if there is anything true, there must be truth. | |
From: Thomas Aquinas (Summa Theologicae [1265], Art 1, Obj 3) | |
A reaction: A classic example of turning the tables, also applicable to anyone who firmly denies knowledge, or that words are meaningful, or says that meaning needs verification. However, one measily truth is not much consolation. |
22104 | Truth is the conformity of being to intellect [Aquinas] |
Full Idea: The word 'true' expresses the conformity of a being to intellect. | |
From: Thomas Aquinas (Disputed questions about truth [1267], I.1c), quoted by Kretzmann/Stump - Aquinas, Thomas 09 | |
A reaction: I believe in a 'robust' theory of truth, but accept that the concept of 'correspondence' has major problems. So I embrace with delight the word 'conformity'. I offer the world The Conformity Theory of Truth! 'Conform' is suitably vague. |
2442 | Inferences are surely part of the causal structure of the world [Fodor] |
Full Idea: Inferences are surely part of the causal structure of the world. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §3) |
23173 | If a syllogism admits one absurdity, others must follow [Aquinas] |
Full Idea: In syllogistic arguments, granted one absurdity, others must follow too. | |
From: Thomas Aquinas (Summa Theologicae [1265], I-II Q19 6) | |
A reaction: This asserts the necessity of logical consequence, which he derives from Aristotle. |
12664 | A truth-table, not inferential role, defines 'and' [Fodor] |
Full Idea: I'm inclined to think that 'and' is defined by its truth-table (and not, for example, by its 'inferential-role'). | |
From: Jerry A. Fodor (LOT 2 [2008], Ch.7) | |
A reaction: Sounds right, on my general principle that something can only have a function if it has an intrinsic nature. The truth-table just formalises normal understanding of 'and', according to what it makes true. |
3005 | 'Jocasta' needs to be distinguished from 'Oedipus's mother' because they are connected by different properties [Fodor] |
Full Idea: If the concept 'Jocasta' needs to be distinguished from the concept 'Oedipus's mother', that's all right because the two concepts are connected with different properties. | |
From: Jerry A. Fodor (Psychosemantics [1987], p. 84) |
12648 | Names in thought afford a primitive way to bring John before the mind [Fodor] |
Full Idea: Names in thought (in contrast to, say, descriptions in thought) afford a primitive way of bringing John before the mind. | |
From: Jerry A. Fodor (LOT 2 [2008], Ch.3 App) | |
A reaction: I think the 'file' account of concepts which Fodor has now latched onto gives a wonderful account of names. They are simple if you haven't opened the file yet (like 'Louis', in Evans's example). |
12650 | 'Paderewski' has two names in mentalese, for his pianist file and his politician file [Fodor] |
Full Idea: Paderewski (as pianist and as politician) has two names in Mentalese. If you think there are two Paderewskis, it's important that what you get when you retrieve the pianist file differs from the politician file. You can then merge the two files. | |
From: Jerry A. Fodor (LOT 2 [2008], Ch.3 App) | |
A reaction: The same will apply to 'Hespherus' and 'Phosphorus'. We can re-separate the 'morning star' and 'evening star' files if we wish to discuss ancient Egyptian attitudes to such things. I love this idea of Fodor's. Explanations flow from it. |
12656 | P-and-Q gets its truth from the truth of P and truth of Q, but consistency isn't like that [Fodor] |
Full Idea: The truth of P-and-Q is (roughly) a function of the truth of P and the truth of Q; but the consistency of P&Q isn't a function of the consistency of P and the consistency of Q. | |
From: Jerry A. Fodor (LOT 2 [2008], Ch.4.5 n33) | |
A reaction: This is a nice deep issue. Fodor is interested in artificial intelligence at this point, but I am interested in the notion of coherence, as found in good justifications. Even consistency isn't elementary logic, never mind coherence. |
12620 | If 'exist' is ambiguous in 'chairs and numbers exist', that mirrors the difference between chairs and numbers [Fodor] |
Full Idea: People say 'exist' is ambiguous, because of the difference between 'chairs exist' and 'numbers exist'. A reply goes: the difference between the existence of chairs and the existence of numbers is strikingly like the difference between chairs and numbers. | |
From: Jerry A. Fodor (Concepts:where cogn.science went wrong [1998], Ch.3) | |
A reaction: To say 'numbers are objects which exist' is, to me, either a funny use of 'exist' or a funny use of 'object'. I think I will now vote for the latter. Just as 'real number' was a funny use of 'number', but we seem to have got used to it. |
11195 | If affirmative propositions express being, we affirm about what is absent [Aquinas] |
Full Idea: If being is what makes propositions true, then anything we can express in an affirmative proposition, however unreal, is said to be; so lacks and absences are, since we say that absences are opposed to presences, and blindness exists in an eye. | |
From: Thomas Aquinas (De Ente et Essentia (Being and Essence) [1267], p.92) | |
A reaction: See Idea 11194 for the alternative Aristotelian approach to being, according to categories. Do absences and lacks have real essences, or causal properties? The absence of the sentry may cause the loss of the city. |
22103 | Being is basic to thought, and all other concepts are additions to being [Aquinas] |
Full Idea: Being is inherently intellect's most intelligible object, in which it finds the basis of all conceptions. ...All of intellect's other conceptions must be arrived at by adding to being, insofar as they express what is not expressed by 'being' itself. | |
From: Thomas Aquinas (Disputed questions about truth [1267], I.1c), quoted by Kretzmann/Stump - Aquinas, Thomas 09 | |
A reaction: I like the word 'intelligible' here. We might know reality, or be aware of appearances, but what is intelligible lies nicely in between. What would Berkeley make of that? I presume 'intelligible' means 'makes good sense'. |
15812 | Being implies distinctness, which implies division, unity, and multitude [Aquinas] |
Full Idea: What first comes to mind is being; secondly, that this being is not that being, and thus we apprehend division as a consequence; thirdly, comes the notion of one; fourthly the notion of multitude. | |
From: Thomas Aquinas (Summa Theologicae [1265], I Q11 ar2 ad4), quoted by Roderick Chisholm - Person and Object 1.5 | |
A reaction: This is one of the best things I have read on 'being'. It is the Aristotelian recognition that we can only study being by studying identity, and that this leads on to wider metaphysics. Other approaches to being are dead ends. |
21268 | Non-human things are explicable naturally, and voluntary things by the will, so God is not needed [Aquinas] |
Full Idea: All natural things can be reduced to one principle, which is nature; and all voluntary things can be reduced to one principle, which is human reason, or will. Therefore God does not exist. | |
From: Thomas Aquinas (Summa Theologicae [1265], Ia,Q02,Art3,Ob2) | |
A reaction: Not, of course, the opinion of Aquinas. So the possibility of naturalism (assuming the human will can be further reduced to nature) was a clear option in the thirteenth century. In reply Aquinas cites his Fifth Way. |
16655 | Different genera are delimited by modes of predication, which rest on modes of being [Aquinas] |
Full Idea: Being is delimited into different genera in accord with different modes of predicating, which depend on different modes of being. | |
From: Thomas Aquinas (On Aristotle's 'Metaphysics' [1266], V.9.890), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 12.3 | |
A reaction: I like this. When people say that predication is the way we divide things up, and go all linguistic-relativist about things, they forget how closely language not only describes reality, but arises out of, or is even caused by, reality. 'Grue' is silly. |
2469 | The world is full of messy small things producing stable large-scale properties (e.g. mountains) [Fodor] |
Full Idea: Damn near everything we know about the world (e.g. a mountain) suggests that unimaginably complicated to-ings and fro-ings of bits and pieces at the extreme microlevel manage somehow to converge on stable macrolevel properties. | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 2) | |
A reaction: This is clearly true, and is a vital part of the physicalist picture of the mind. Personally I prefer the word 'processes' to 'properties', since no one seems to really know what a property is. A process is an abstraction from events. |
11201 | Properties have an incomplete essence, with definitions referring to their subject [Aquinas] |
Full Idea: Incidental properties have an incomplete essence, and need to refer in their definitions to their subject, lying outside their own genus. | |
From: Thomas Aquinas (De Ente et Essentia (Being and Essence) [1267], p.93) | |
A reaction: These are 'incidental' properties, but it is a nice question whether properties have essences. Presumably they must have if they are universals, or platonic Forms. The notion of being 'strong' can be defined without specific examples. |
16641 | Whiteness does not exist, but by it something can exist-as-white [Aquinas] |
Full Idea: Whiteness is said to exist not because it subsists in itself, but because by it something has existence-as-white. | |
From: Thomas Aquinas (Quodlibeta [1267], IX.2.2), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 10.2 | |
A reaction: It seems unavoidable to refer to the whiteness as 'it'. It might be called the 'adverbial' theory of properties, as ways of doing something. |
7014 | A particle and a coin heads-or-tails pick out to perfectly well-defined predicates and properties [Fodor] |
Full Idea: 'Is a particle and my coin is heads' and 'is a particle and my coin is tails' are perfectly well defined predicates and they pick out perfectly well defined (relational) properties of physical particles. | |
From: Jerry A. Fodor (Psychosemantics [1987], Ch.2) | |
A reaction: (Somewhat paraphrased). This is a very nice offering for the case that all predicates are properties, and hence that 'properties' is an entirely conventional category. It strikes me as self-evident that Fodor is not picking out 'natural' properties. |
12613 | Empiricists use dispositions reductively, as 'possibility of sensation' or 'possibility of experimental result' [Fodor] |
Full Idea: Using dispositional analyses in aid of ontological reductions is what empiricism taught us. If you are down on cats, reduce them to permanent possibilities of sensation; if you are down on electrons, reduce them to possibilities of experimental outcome. | |
From: Jerry A. Fodor (Concepts:where cogn.science went wrong [1998], Ch.1) | |
A reaction: The cats line is phenomenalism; the electrons line is instrumentalism. I like this as a serious warning about dispositions, even where they seem most plausible, as in the disposition of glass to break when struck. Why is it thus disposed? |
2475 | Don't define something by a good instance of it; a good example is a special case of the ordinary example [Fodor] |
Full Idea: It's a mistake to try to construe the notion of an instance in terms of the notion of a good instance (e.g. Platonic Forms); the latter is patently a special case of the former, so the right order of exposition is the other way round. | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 4) |
11205 | If the form of 'human' contains 'many', Socrates isn't human; if it contains 'one', Socrates is Plato [Aquinas] |
Full Idea: If (in the Platonic view) manyness was contained in humanness it could never be one as it is in Socrates, and if oneness was part of its definition then Socrates would be Plato and the nature couldn't be realised more than once. | |
From: Thomas Aquinas (De Ente et Essentia (Being and Essence) [1267], p.100) | |
A reaction: I suppose the reply is that since we are trying to explain one-over-many, then this unusual combination of both manyness and oneness is precisely what distinguishes forms from other ideas. |
13090 | The principle of diversity for corporeal substances is their matter [Aquinas, by Cover/O'Leary-Hawthorne] |
Full Idea: In the view of Aquinas, while substantial form is the ultimate ground of identity and difference of angels, it is matter that provides a principle of diversity in the case of corporeal substances. | |
From: report of Thomas Aquinas (De Ente et Essentia (Being and Essence) [1267]) by Cover,J/O'Leary-Hawthorne,J - Substance and Individuation in Leibniz 5.2.3 | |
A reaction: This is at least as good a proposal as their apatial location. There is more chance of reidentifying matter than of precisely reidentifying a spatial location. Two indistinguishable spheres remain the classic problem case (of Max Black, Idea 10195) |
17555 | 'One' can mean undivided and not a multitude, or it can add measurement, giving number [Aquinas] |
Full Idea: There are two sorts of one. There is the one which is convertible with being, which adds nothing to being except being undivided; and this deprives of multitude. Then there is the principle of number, which to the notion of being adds measurement. | |
From: Thomas Aquinas (Quaestiones de Potentia Dei [1269], q3 a16 ad 3-um) | |
A reaction: [From a lecture handout] I'm not sure I understand this. We might say, I suppose, that insofar as water is water, it is all one, but you can't count it. Perhaps being 'unified' and being a 'unity' are different? |
16765 | Humans only have a single substantial form, which contains the others and acts for them [Aquinas] |
Full Idea: A human being has no substantial form other than the intellective soul alone, and it contains the sensitive and nutritive souls, and all lower forms, and it alone brings about whatever it is that less perfect forms bring about in other things. | |
From: Thomas Aquinas (Summa Theologicae [1265], Ia Q76 4c), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 25.1 | |
A reaction: He says brutes and plants also have a single soul. Pasnau says this is Aquinas's most distinctive doctrine, because other thinkers postulate a whole hierarchy of substantial forms. |
16766 | One thing needs a single thing to unite it; if there were two forms, something must unite them [Aquinas] |
Full Idea: One thing simpliciter is produced out of many actually existing things only if there is something uniting and tying them to each other. If Socrates were animal and rational by different forms, then to be united they would need something to make them one. | |
From: Thomas Aquinas (Quaestiones de anima [1269], 11c), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 25.2 | |
A reaction: This is the reply to the idea that a single thing is just an interesting of many sortal essences. It presumes, of course, that a thing like a horse has something called 'unity'. |
11202 | It is by having essence that things exist [Aquinas] |
Full Idea: It is by having essence that things exist. | |
From: Thomas Aquinas (De Ente et Essentia (Being and Essence) [1267], p.94) | |
A reaction: Compare Idea 11199, which gives a fuller picture. This idea seems to suggest essence as the cause of existence, which sounds wrong. Perhaps essence is a necessary condition of existence, but it is necessary that nothing indeterminate can exist? |
11203 | Specific individual essence is defined by material, and generic essence is defined by form [Aquinas] |
Full Idea: Specific essence differs from generic essence by being demarcated: individuals are demarcated within species by dimensionally defined material, but species within genus by a defining differentiation taken from the form. | |
From: Thomas Aquinas (De Ente et Essentia (Being and Essence) [1267], p.95) | |
A reaction: It clearly won't be enough to define an individual just to define its material and its shape. The material might also be essential to the genus, as when defining fire. Probably not very helpful. |
11200 | The definition of a physical object must include the material as well as the form [Aquinas] |
Full Idea: Form alone cannot be a composite substance's essence. For a thing's essence is expressed by its definition, and unless the definition of a physical substance included both form and material, the definition wouldn't differ from mathematical objects. | |
From: Thomas Aquinas (De Ente et Essentia (Being and Essence) [1267], p.93) | |
A reaction: This is the sort of thoroughly sensible remark that you only get from the greatest philosophers. Minor philosophers fall in love with things like forms, and then try to use them to explain everything. |
11196 | Essence is something in common between the natures which sort things into categories [Aquinas] |
Full Idea: Since being as belonging to a category expresses the 'isness' of things, and belongs to all ten Aristotelian categories, essence must be something all the natures that sort different beings into genera and species have in common. | |
From: Thomas Aquinas (De Ente et Essentia (Being and Essence) [1267], p.92) | |
A reaction: I like this because it is the essence which does the sorting, not the sorting which defines the essence (which seems to me to be a deep and widespread confusion). |
11208 | A simple substance is its own essence [Aquinas] |
Full Idea: A simple substance is its own essence. | |
From: Thomas Aquinas (De Ente et Essentia (Being and Essence) [1267], p.103) | |
A reaction: Aquinas takes complex substances to have their essences in various ways, but this thought is the basis of all essence. Presumably the Greek word 'ousia' names the key ingredient. |
12653 | There's statistical, logical, nomological, conceptual and metaphysical possibility [Fodor] |
Full Idea: Statistically, logically, nomologically, conceptually, and metaphysically possible. That's all the kinds of possibility there are this week, but feel free to add others. | |
From: Jerry A. Fodor (LOT 2 [2008], Ch.4.3) | |
A reaction: There's also epistemic possibility (possibility 'for all I know'), but I suppose that isn't the real thing. How about 'imaginative possibility' (possibility 'as far as I can imagine')? |
22170 | Senses grasp external properties, but the understanding grasps the essential natures of things [Aquinas] |
Full Idea: Our imagination and senses grasp only the outer properties of things, not their natures. ...Understanding, however, grasps the very substance and nature of things, so that what is represented in understanding is a likeness of thing's very essence. | |
From: Thomas Aquinas (Quodlibeta [1267], 8.2.2) | |
A reaction: This is exactly the picture I endorse for modern science. Explanation is the path to understanding, and that must venture beyond immediate experience. |
12651 | Some beliefs are only inferred when needed, like 'Shakespeare had not telephone' [Fodor] |
Full Idea: Maybe some of your beliefs are inferred 'online' from what you have in your files, along with your inferential rules. 'Shakespeare didn't have a telephone' is a classic example, which we infer if the occasion arises. | |
From: Jerry A. Fodor (LOT 2 [2008], Ch.3 App) | |
A reaction: A highly persuasive example. There seem to be a huge swathe of blatantly obvious beliefs (especially negative ones) which may never cross our minds during an entire lifetime, but to which we certainly subscribe. |
2502 | How do you count beliefs? [Fodor] |
Full Idea: There is no agreed way of counting beliefs. | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch.16) |
12628 | Knowing that must come before knowing how [Fodor] |
Full Idea: Thought about the world is prior to thought about how to change the world. Accordingly, knowing that is prior to knowing how. Descartes was right, and Ryle was wrong. | |
From: Jerry A. Fodor (LOT 2 [2008], Ch.1) | |
A reaction: The classical example is knowing how to ride a bicycle, when few people can explain what is involved. Clearly you need quite a bit of propositional knowledge before you step on a bike. How does Fodor's claim work for animals? |
23175 | The conclusions of speculative reason about necessities are certain [Aquinas] |
Full Idea: Since the speculative reason is concerned chiefly with necessary things, which cannot be otherwise than they are, its proper conclusions, like the universal principles, contain the truth without fail. | |
From: Thomas Aquinas (Summa Theologicae [1265], I-II Q94 4) | |
A reaction: This seems over-confident, and to confuse the facts with our knowledge of the facts. Simple arithmetic may seem certain, but long and intricate proofs are always a little uncertain. |
21337 | A knowing being possesses a further reality, the 'presence' of the thing known [Aquinas] |
Full Idea: Knowing beings are differentiated from non-knowing beings by this: non-knowing beings have only their own reality, but knowing beings are capable of possessing also the reality of something else, ...a presence of the thing known produced by this thing. | |
From: Thomas Aquinas (Summa Theologicae [1265], Ia,q.Q14,art 1) | |
A reaction: [Quoted by Ryan Meade in a talk at Pigotts] A famous and much discussed remark. Aquinas was a direct realist about perception, so this presence seems to be the thing itself, rather than a 'representation'. |
2501 | Berkeley seems to have mistakenly thought that chairs are the same as after-images [Fodor] |
Full Idea: Berkeley seems to have believed that tables and chairs are logically homogeneous with afterimages. I assume that he was wrong to believe this. | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch.16) |
21249 | Some things are self-evident to us; others are only self-evident in themselves [Aquinas] |
Full Idea: A thing can be self-evident in either of two ways: on the one hand, self-evident in itself, though not to us; on the other hand, self-evident in itself, and to us. | |
From: Thomas Aquinas (Summa Theologicae [1265], Art 1, Obj 3) | |
A reaction: A clear distinction, which is hard to deny, though there are lots of borderline cases. Self-evident to genius, and self-evident to future genius. Self-evident to almost everyone. Goldbach's Conjecture may be self-evident but unknowable. |
22169 | Initial universal truths are present within us as potential, to be drawn out by reason [Aquinas] |
Full Idea: For present in us by nature are certain initial truths everyone knows, in which lie potentially known conclusions our reasons can draw out and make actually known. | |
From: Thomas Aquinas (Quodlibeta [1267], 8.2.2) | |
A reaction: Note that these are truths rather than concepts, but that they have to be 'drawn out' by reason. This is Descartes' view of the matter, where the 'natural light' of reason is needed to articulate what is innate, such as geometry. |
3009 | Sticklebacks have an innate idea that red things are rivals [Fodor] |
Full Idea: God gave the male stickleback the idea that whatever is red is a rival. | |
From: Jerry A. Fodor (Psychosemantics [1987], p.133) |
3008 | Evolution suggests that innate knowledge of human psychology would be beneficial [Fodor] |
Full Idea: If I had to design homo sapiens, I would have made commonsense knowledge of homo sapiens psychology innate; that way nobody would have to spend time learning it. | |
From: Jerry A. Fodor (Psychosemantics [1987], p.132) |
2990 | Contrary to commonsense, most of what is in the mind seems to be unlearned [Fodor] |
Full Idea: Contrary to commonsense, it looks as though much of what is in the mind is unlearned. | |
From: Jerry A. Fodor (Psychosemantics [1987], p. 15) |
21250 | A proposition is self-evident if the predicate is included in the essence of the subject [Aquinas] |
Full Idea: A proposition is self-evident because the predicate is included in the essence of the subject. E.g. Man is an animal, because animal is included in the essence of man. | |
From: Thomas Aquinas (Summa Theologicae [1265], Art 1, Obj 3) | |
A reaction: Aquinas focuses on the essence of the subject, where Kant embraces the whole concept of the subject. Is it self-evident that we are genetically related to apes? Yes, to a geneticiist. Is that part of human essence? No. So Kant wins. |
22168 | Minds take in a likeness of things, which activates an awaiting potential [Aquinas] |
Full Idea: What the mind takes in is not some material element of the agent, but a likeness of the agent actualising some potential the patient already has. This, for example, is the way our seeing takes in the colour of a coloured body. | |
From: Thomas Aquinas (Quodlibeta [1267], 8.2.1) | |
A reaction: This is exactly right. Descartes agreed. It works for colour, but not (obviously) for cheese graters. |
2465 | Maybe explaining the mechanics of perception will explain the concepts involved [Fodor] |
Full Idea: Why mightn't fleshing out the standard psychological account of perception itself count as learning what perceptual justification amounts to? | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 1) |
20224 | Sensation prepares the way for intellectual knowledge, which needs the virtues of reason [Aquinas] |
Full Idea: Knowledge of truth is not consummated in the sensitive powers of apprehension, for these prepare the way to intellectual knowledge. And therefore in these powers there are none of the virtues by which we know truth; these are in the intellect or reason. | |
From: Thomas Aquinas (Summa Theologicae [1265], I-II Q56 a5 obj3), quoted by Linda Trinkaus Zagzebski - Virtues of the Mind III 2.2 | |
A reaction: A gem of a quotation for Zagzebski's thesis, that knowledge is defined in terms of the intellectual virtues. The only virtues of perception are in focusing and paying attention to features. Good eyesight is a biological 'virtue', I suppose. |
2504 | Rationalism can be based on an evolved computational brain with innate structure [Fodor] |
Full Idea: Pinker's rationalism involves four main ideas: mind is a computational system, which is massively modular with a lot of innate structure resulting from evolution. | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch.17) |
3978 | Associations are held to connect Ideas together in the way the world is connected together [Fodor] |
Full Idea: The laws of associations were held to explicate the semantic coherence of intentional processes, which adjust the causal relations among Ideas to reflect corresponding relations among the things that they're ideas of. | |
From: Jerry A. Fodor (Jerry A. Fodor on himself [1994], p.296) | |
A reaction: With the support of evolution, and the backing of a correspondence theory of truth, plus more sophistication in the associations, this might work. |
12617 | Associationism can't explain how truth is preserved [Fodor] |
Full Idea: The essential problem is to explain how thinking manages reliably to preserve truth; and Associationism, as Kant rightly pointed out to Hume, hasn't the resources to do so. | |
From: Jerry A. Fodor (Concepts:where cogn.science went wrong [1998], Ch.1) | |
A reaction: One might be able to give an associationist account of truth-preservation if one became a bit more externalist about it, so that the normal association patterns track their connections with the external world. |
2493 | According to empiricists abstraction is the fundamental mental process [Fodor] |
Full Idea: According to empiricists, the fundamental mental process is not theory construction but abstraction. | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch.12) |
12625 | Pragmatism is the worst idea ever [Fodor] |
Full Idea: Pragmatism is perhaps the worst idea that philosophy ever had. | |
From: Jerry A. Fodor (LOT 2 [2008], Ch.1) | |
A reaction: Not an argument, but an interesting sign of the times. Most major modern American philosophers, such as Quine, seem to fit some loose label of 'pragmatist'. I always smell a feeble relativism, and a refusal to face the interesting questions. |
1860 | Knowledge may be based on senses, but we needn't sense all our knowledge [Aquinas] |
Full Idea: All our knowledge comes through our senses, but that doesn't mean that everything we know is sensed. | |
From: Thomas Aquinas (Quaestiones Disputatae de Malo [1271], Q6.h to 18) |
2494 | Rationalists say there is more to a concept than the experience that prompts it [Fodor] |
Full Idea: That there is more in the content of a concept than there is in the experiences that prompt us to form it is the burden of the traditional rationalist critique of empiricism (as worked out by Leibniz and Kant). | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch.12) |
22109 | The fullest knowledge places a conclusion within an accurate theory [Aquinas, by Kretzmann/Stump] |
Full Idea: Having 'scientia' is the fullest possible human cognition, by which one situates the fact expressed by a conclusion in an explanatory theory that accurately maps metaphysical or physical reality. | |
From: report of Thomas Aquinas (Sententia on 'Posterior Analytics' [1269], 1.2.9, 1.5.7) by Kretzmann/Stump - Aquinas, Thomas 11 | |
A reaction: That is a perfect statement of my concept of knowledge. Explanatory theories must specify the essential natures of the entities involved. We don't aim for 'knowledge', we aim for the 'fullest possible cognition'. This account extend's Aristotle's. |
2462 | Control of belief is possible if you know truth conditions and what causes beliefs [Fodor] |
Full Idea: Premeditated cognitive management is possible if knowing the contents of one's thoughts would tell you what would make them true and what would cause you to have them. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §4) | |
A reaction: I love the idea of 'cognitive management'. Since belief is fairly involuntary, I subject myself to the newspapers, books, TV and conversation which will create the style of beliefs to which I aspire. Why? |
2454 | We can deliberately cause ourselves to have true thoughts - hence the value of experiments [Fodor] |
Full Idea: A creature that knows what makes its thoughts true and what would cause it to have them, could therefore cause itself to have true thoughts. …This would explain why experimentation is so close to the heart of our cognitive style. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §4) |
2455 | Interrogation and experiment submit us to having beliefs caused [Fodor] |
Full Idea: You can put yourself into a situation where you may be caused to believe that P. Putting a question to someone who is in the know is one species of this behaviour, and putting a question to Nature (an experiment) is another. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §4) |
2460 | Participation in an experiment requires agreement about what the outcome will mean [Fodor] |
Full Idea: To be in the audience for an experiment you have to believe what the experimenter believes about what the outcome would mean, but not necessarily what the outcome will be. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §4) |
2461 | An experiment is a deliberate version of what informal thinking does all the time [Fodor] |
Full Idea: Experimentation is an occasional and more or less self-conscious exercise in what informal thinking does all the time without thinking about it. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §4) |
2458 | Theories are links in the causal chain between the environment and our beliefs [Fodor] |
Full Idea: Theories function as links in the causal chains that run from environmental outcomes to the beliefs that they cause the inquirer to have. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §4) |
11198 | Definition of essence makes things understandable [Aquinas] |
Full Idea: It is definition of essence that makes things understandable. | |
From: Thomas Aquinas (De Ente et Essentia (Being and Essence) [1267], p.92) | |
A reaction: The aim of philosophy is understanding, which is achieved by successful explanation. I totally agree with this Aristotelian view, so neatly summarised by Aquinas. |
2503 | Empirical approaches see mind connections as mirrors/maps of reality [Fodor] |
Full Idea: Empirical approaches to cognition say the human mind is a blank slate at birth; experiences write on the slate, and association extracts and extrapolates trends from the record of experience. The mind is an image of statistical regularities of the world. | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch.17) | |
A reaction: The 'blank slate' is an exaggeration. The mind at least has the tools to make associations. He tries to make it sound implausible, but the word 'extrapolates' contains a wealth of possibilities that could build into a plausible theory. |
2508 | The function of a mind is obvious [Fodor] |
Full Idea: Like hands, you don't have to know how the mind evolved to make a pretty shrewd guess at what it's for; for example, that it's to think with. | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch.17) | |
A reaction: I like this. This is one of the basic facts of philosophy of mind, and it frequently gets lost in the fog. It is obvious that the components of the mind (say, experience and intentionality) will be better understood if their function is remembered. |
12636 | Mental states have causal powers [Fodor] |
Full Idea: Mental states have causal powers. | |
From: Jerry A. Fodor (LOT 2 [2008], Ch.2.3) | |
A reaction: I quote this because it gives you the link between a general account of causal powers as basic to reality, and an active account of what the mind is. It has to be a key link in a decent modern unified account of the world. See Idea 12638. |
2994 | In CRTT thought may be represented, content must be [Fodor] |
Full Idea: In the Representation Theory of Mind, programs (the 'laws of thought') may be explicitly represented, but data structures (the 'contents of thought') have to be. | |
From: Jerry A. Fodor (Psychosemantics [1987], p. 25) | |
A reaction: Presumably this is because content is where mental events actually meet up with the reality being considered. It may be an abstract procedure, but if it doesn't plug into reality then it isn't thought, but merely activity, like that of the liver. |
2443 | I say psychology is intentional, semantics is informational, and thinking is computation [Fodor] |
Full Idea: I hold that psychological laws are intentional, that semantics is purely informational, and that thinking is computation (and that it is possible to hold all of these assumptions at once). | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §4) | |
A reaction: When he puts it baldly like that, it doesn't sound terribly persuasive. Thinking is 'computation'? Raw experience is irrelevant? What is it 'like' to spot an interesting connection between two propositions or concepts? It's not like adding 7 and 5. |
2453 | We are probably the only creatures that can think about our own thoughts [Fodor] |
Full Idea: I think it is likely that we are the only creatures that can think about the contents of our thoughts. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §4) | |
A reaction: I think this is a major idea. If you ask me the traditional question - what is the essential difference between us and other animals? - this is my answer (not language, or reason). We are the metathinkers. |
15473 | How does anything get outside itself? [Fodor, by Martin,CB] |
Full Idea: Fodor asks the stirring and basic question 'How does anything get outside itself?' | |
From: report of Jerry A. Fodor (works [1986]) by C.B. Martin - The Mind in Nature 03.6 | |
A reaction: Is this one of those misconceived questions, like major issues concerning 'what's it like to be?' In what sense am I outside myself? Is a mind any more mysterious than a shadow? |
2485 | Do intentional states explain our behaviour? [Fodor] |
Full Idea: Intentional Realism is the idea that our intentional mental states causally explain our behaviour; so holistic semantics (which says no two people have the same intentional states, or share generalisations) is irrealistic about intentional mental states. | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 6) | |
A reaction: ...presumably because two people CAN have the same behaviour. The key question would be whether the intentional states have to be conscious. |
2981 | Is intentionality outwardly folk psychology, inwardly mentalese? [Lyons on Fodor] |
Full Idea: For Fodor the intentionality of the propositional-attitude vocabulary of our folk psychology is the outward expression of the inward intentionality of the language of the brain. | |
From: comment on Jerry A. Fodor (works [1986]) by William Lyons - Approaches to Intentionality p.39 | |
A reaction: I would be very cautious about this. Folk psychology works, so it must have a genuine basis in how brains work, but it breaks down in unusual situations, and might even be a total (successful) fiction. |
7326 | Intentionality doesn't go deep enough to appear on the physicists' ultimate list of things [Fodor] |
Full Idea: Sooner or later the physicists will complete the catalogue of ultimate and irreducible things, with the likes of spin, charm and charge. But aboutness won't be on the list; intentionality simply doesn't go that deep. | |
From: Jerry A. Fodor (Psychosemantics [1987], 4 Intro) | |
A reaction: I totally agree with this, which I take to be a warning to John Searle against including something called 'intrinsic intentionality' into his ontology. Intentionality 'emerges' out of certain complex brain activity. |
15494 | We can't use propositions to explain intentional attitudes, because they would need explaining [Fodor] |
Full Idea: It's not clear what the point would be of an explanation of the intentionality of attitudes which presupposes objects that are intentional intrinsically. Why not just say that the attitudes are? | |
From: Jerry A. Fodor (Psychosemantics [1987], Ch.3) |
3976 | Intentional science needs objects with semantic and causal properties, and which obey laws [Fodor] |
Full Idea: If there is to be an intentional science, there must be semantically evaluable things which have causal powers, and there must be laws relating beliefs and desires to one another, and to actions. | |
From: Jerry A. Fodor (Jerry A. Fodor on himself [1994], p.293) | |
A reaction: The semantics and causation sound fair enough, but the prospect of finding laws looks bleak (though, contrary to Davidson, I don't see why they can't exist). |
3980 | Intentional states and processes may be causal relations among mental symbols [Fodor] |
Full Idea: It may be that intentional states are relations to mental symbols, and mental processes are implemented by causal relations among these symbols. | |
From: Jerry A. Fodor (Jerry A. Fodor on himself [1994], p.296) | |
A reaction: It is hard to see how something could have causal powers just by being a symbol. The theory needs something else to drive the causation. |
22107 | Sensations are transmitted to 'internal senses' in the brain, chiefly to 'phantasia' and 'imagination' [Aquinas, by Kretzmann/Stump] |
Full Idea: Sensory species received in external senses are transmitted to 'internal senses', organs located in the brain. The most important of these for cognition are 'phantasia' and 'imagination' (part of phantasia), which produce and preserve 'phantasms'. | |
From: report of Thomas Aquinas (Summa Theologicae [1265]) by Kretzmann/Stump - Aquinas, Thomas 11 | |
A reaction: This seems to make Aquinas a representative realist. I add this to my portfolio of philosophical faculties - those required by philosophy, rather than by psychology or neuroscience. |
9098 | Mental activity combines what we sense with imagination of what is not present [Aquinas] |
Full Idea: Mental activity combines two activities which in the senses are distinct: exterior perception in which we are simply affected by what we sense, and interior imagination in which we create images of things that are not, and never have been present. | |
From: Thomas Aquinas (Summa Theologicae [1265], Ch.5 Q85.2) | |
A reaction: Geach cites this thought to show that he is anti-abstractionist, since mind creates images, and these can arise from things which have not been experienced. Any defence of abstractionism must allow an active power to imagination. |
9092 | Abstracting A from B generates truth, as long as the connection is not denied [Aquinas] |
Full Idea: Abstacting A from B can mean denying A's connection with B, or simply thinking A without thinking B. Abstracting what in reality is connected generates falsehood if done the first way, but not if done the second. | |
From: Thomas Aquinas (Summa Theologicae [1265], Ch.5 Q85.1) | |
A reaction: Despite Geach's denials, this seems to make Aquinas a classic abstractionist. He goes on to distinguish two sorts of abstraction, but he certainly thinks of abstraction from sense experience as a revelation about the nature of reality. |
9093 | We understand the general nature of things by ignoring individual peculiarities [Aquinas] |
Full Idea: If we think what defines a stone, man or horse, without thinking of any individual peculiarities it may have, this is precisely what we do when we abstract the general nature of what we understand from any particular way in which we imagine it. | |
From: Thomas Aquinas (Summa Theologicae [1265], Ch.5 Q85.1) | |
A reaction: This may not be simple abstraction from sense experience, since there would obviously be a threatened circularity in the process. Do you need to know the essential definition first, in order to discard the individual peculiarities? |
9097 | The mind abstracts generalities from images, but also uses images for understanding [Aquinas] |
Full Idea: Our mind both abstracts the species from images when it attends to the general nature of things, and understand the species in the images when it has recourse to the images in order to understand the things whose species it has abstracted. | |
From: Thomas Aquinas (Summa Theologicae [1265], Ch.5 Q85.1) | |
A reaction: Geach claims that the second half of this idea means that Aquinas is not an abstractionist, but he seems to be explictly abstractionist about the way in which we create higher level concepts from lower ones. |
9095 | Very general ideas (being, oneness, potentiality) can be abstracted from thought matter in general [Aquinas] |
Full Idea: There are even things we can abstract from thought matter in general, things like being and oneness and potentiality and realization. | |
From: Thomas Aquinas (Summa Theologicae [1265], Ch.5 Q85.1) | |
A reaction: The Aristotelian 'potentiality' means possibility, which means that modality is understood by abstraction. Aquinas seems to have four levels: particular perceived, general perceived, particular thought, and general thought. This is the highest level. |
9099 | Particular instances come first, and (pace Plato) generalisations are abstracted from them [Aquinas] |
Full Idea: The generality attaching to a nature - its relatedness to many particular instances - results from abstraction, so in this sense a generalized nature presupposes its instances, and does not, as Plato thought, precede them. | |
From: Thomas Aquinas (Summa Theologicae [1265], Ch.5 Q85.2) | |
A reaction: This seems to be a quite explicit endorsement of abstractionism by Aquinas, despite all Geach's assertions to the contrary. |
10508 | Species are abstracted from appearances by ignoring individual conditions [Aquinas] |
Full Idea: The agent intellect abstracts intelligible species from phantasms insofar as through the power of the agent intellect we can take into our consideration the natures of the species without the individual conditions. | |
From: Thomas Aquinas (Summa Theologicae [1265], Q85 Ad4) | |
A reaction: There might be a threatened circularity here, in trying to decide which features to ignore and which to retain. If we saw a hundred horses with a white nose blaze, we still wouldn't be sure that this was essential to a horse. Innate notions of species?? |
12661 | The different types of resemblance don't resemble one another [Fodor] |
Full Idea: The ways in which different kinds of thing are similar to one another aren't, in general, similar to one another. | |
From: Jerry A. Fodor (LOT 2 [2008], Ch.5.4) | |
A reaction: Nice, but I think one would say that they lack similarity at the level of primary thought, but have obvious similarity (as concept-connectors) at the level of meta-thought. |
2506 | If I have a set of mental modules, someone had better be in charge of them! [Fodor] |
Full Idea: If there is a community of computers living in my head, there had also better be somebody who is in charge; and, by God, it had better be me. | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch.17) | |
A reaction: Dennett quotes this as a quaintly old-fashioned view. I agree quite strongly with Fodor, for reasons that Dennett should like - evolutionary ones. A mind is a useless tool without central co-ordination. What makes my long-term plans? It isn't anarchy! |
22111 | Aquinas attributes freedom to decisions and judgements, and not to the will alone [Aquinas, by Kretzmann/Stump] |
Full Idea: Aquinas conceives of freedom as free decision or judgement, which cannot be attributed to the will alone. | |
From: report of Thomas Aquinas (Summa Theologicae [1265]) by Kretzmann/Stump - Aquinas, Thomas 12 | |
A reaction: This idea might improve the free will debate considerably, because it is not clear what sort of thing a 'will' is, and it is not clear how an entity can be 'free' in isolation, by its intrinsic nature. Isn't all freedom contextual? |
1855 | If we saw something as totally and utterly good, we would be compelled to will it [Aquinas] |
Full Idea: Something apprehended to be good and appropriate in any and every circumstance that could be thought of would compel us to will it. | |
From: Thomas Aquinas (Quaestiones Disputatae de Malo [1271], Q6.reply) |
1861 | The will is not compelled to move, even if pleasant things are set before it [Aquinas] |
Full Idea: The will is not compelled to move, for it doesn't have to want the pleasant things set before it. | |
From: Thomas Aquinas (Quaestiones Disputatae de Malo [1271], Q6.h to 21) |
1856 | Nothing can be willed except what is good, but good is very varied, and so choices are unpredictable [Aquinas] |
Full Idea: Nothing can be willed except good, but many and various things are good, and you can't conclude from this that wills are compelled to choose this or that one. | |
From: Thomas Aquinas (Quaestiones Disputatae de Malo [1271], Q6.h to 05) |
1849 | Since will is a reasoning power, it can entertain opposites, so it is not compelled to embrace one of them [Aquinas] |
Full Idea: Reasoning powers can entertain opposite objects. Now will is a reasoning power, so will can entertain opposites and is not compelled to embrace one of them. | |
From: Thomas Aquinas (Quaestiones Disputatae de Malo [1271], Q6.x2) |
1853 | Because the will moves by examining alternatives, it doesn't compel itself to will [Aquinas] |
Full Idea: Because will moves itself by deliberation - a kind of investigation which doesn't prove some one way correct but examines the alternatives - will doesn't compel itself to will. | |
From: Thomas Aquinas (Quaestiones Disputatae de Malo [1271], Q6.reply) |
1862 | However habituated you are, given time to ponder you can go against a habit [Aquinas] |
Full Idea: However habituated you are, given time to ponder you can go against a habit. | |
From: Thomas Aquinas (Quaestiones Disputatae de Malo [1271], Q6.h to 24) |
1854 | We must admit that when the will is not willing something, the first movement to will must come from outside the will [Aquinas] |
Full Idea: We are forced to admit that, in any will that is not always willing, the very first movement to will must come from outside, stimulating the will to start willing. | |
From: Thomas Aquinas (Quaestiones Disputatae de Malo [1271], Q6.reply) | |
A reaction: cf Nietzsche |
22105 | The human intellectual soul is an incorporeal, subsistent principle [Aquinas] |
Full Idea: It is necessary to say that that which is the principle of intellective activity, what we call the soul of a human being, is an incorporeal, subsistent principle. | |
From: Thomas Aquinas (Summa Theologicae [1265], Ia.Q75 2c), quoted by Kretzmann/Stump - Aquinas, Thomas 10 | |
A reaction: Note 'subsistent' rather than 'existent' (capable of independence?). This identifies the immortal soul with the conscious mind. 'Principle' is an odd word, presumably with roots in Aristotle. It seems to be an Aristotelian 'form' [morphe]. |
2445 | Semantics v syntax is the interaction problem all over again [Fodor] |
Full Idea: The question how mental representations could be both semantic, like propositions, and causal, like rocks, trees, and neural firings, is arguably just the interaction problem all over again. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §4) | |
A reaction: Interesting way of presenting the problem. If you seem to be confronting the interaction problem, you have probably drifted into a bogus dualist way of thinking. Retreat, and reformulate you questions and conceptual apparatus, till the question vanishes. |
2446 | Cartesians consider interaction to be a miracle [Fodor] |
Full Idea: The Cartesian view is that the interaction problem does arise, but is unsolvable because interaction is miraculous. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §4) | |
A reaction: A rather unsympathetic statement of the position. Cartesians might think that God could explain to us how interaction works. Cartesians are not mysterians, I think, but they see no sign of any theory of interaction. |
20700 | Without God's influence every operation would stop, so God causes everything [Aquinas] |
Full Idea: If God's divine influence stopped, every operation would stop. Every operation, therefore, of everything is traced back to him as cause. | |
From: Thomas Aquinas (Summa Contra Gentiles [1268], III.67), quoted by Brian Davies - Introduction to the Philosophy of Religion 3 'Freedom' | |
A reaction: If the systematic interraction of mind and body counts as an 'operation', then this seems to imply Occasionalism. |
2599 | Either intentionality causes things, or epiphenomenalism is true [Fodor] |
Full Idea: The avoidance of epiphenomenalism requires making it plausible that intentional properties can meet sufficient conditions for causal responsibility. | |
From: Jerry A. Fodor (Making Mind Matter More [1989], p.154) | |
A reaction: A wordy way of saying we either have epiphenomenalism, or the mind had better do something - and a good theory will show how. The biggest problem of the mind may not be Chalmer's Hard Question (qualia), but how thought-contents cause things. |
3001 | Behaviourism has no theory of mental causation [Fodor] |
Full Idea: Behaviourists had trouble providing a robust construal of mental causation (and hence had no logical space for a psychology of mental processes). | |
From: Jerry A. Fodor (Psychosemantics [1987], p. 67) | |
A reaction: If they could reduce all mental events to stimulus-response, that seems to fall within the normal procedures of physical causation. There is no problem of mental causation if your ontology is entirely physical. |
2467 | Functionalists see pains as properties involving relations and causation [Fodor] |
Full Idea: Functionalists claim that pains and the like are higher-order, relational properties that things have in virtue of the pattern of causal interactions that they (can or do) enter into. | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 2) | |
A reaction: The whole idea of a property being purely 'relational' strikes me as dubious (or even nonsense). "Is north of" is a relation, but it is totally derived from more basical physical geographical properties. |
2993 | Any piece of software can always be hard-wired [Fodor] |
Full Idea: For any machine that computes a function by executing an explicit algorithm, there exists a hard-wired machine that computes the same function by not executing an explicit algorithm. | |
From: Jerry A. Fodor (Psychosemantics [1987], p. 23) | |
A reaction: It is certainly vital for functionalists to understand that software can be hardwired. Presumably we should understand a hardwired alogirthm as 'implicit'? |
12632 | In the Representational view, concepts play the key linking role [Fodor] |
Full Idea: If the Representational Theory of Mind is true, then concepts are constituents of beliefs, the units of semantic evaluation, a locus of causal interactions among mental representations, and formulas in Mentalese. | |
From: Jerry A. Fodor (LOT 2 [2008], Ch.2.1) | |
A reaction: I like this aspect of the theory, but then I can't really think of a theory about how the mind works that doesn't make concepts central to it. |
3011 | Causal powers must be a crucial feature of mental states [Fodor] |
Full Idea: Everybody is a functionalist, in that we all hold that mental states are individuated, at least in part, by reference to their causal powers. | |
From: Jerry A. Fodor (Psychosemantics [1987], p.138) | |
A reaction: I might individuate the Prime Minister by the carnation in his buttonhole. However, even a dualist must concede that we individuate mental faculties by their role within the mind. |
5498 | Mind is a set of hierarchical 'homunculi', which are made up in turn from subcomponents [Fodor, by Lycan] |
Full Idea: Fodor sees behaviour as manifestations of psychological capacities, which result from the subject being a set of interconnected 'homunculi', which in turn have subcomponents, all of it arranged in a hierarchy. | |
From: report of Jerry A. Fodor (Psychosemantics [1987]) by William Lycan - Introduction - Ontology p.9 | |
A reaction: This may well miss out the most interesting parts of a mind (such as awareness, and personal identity), but it sounds basically right, especially when an evolutionary history is added to the system. Parts of my mind intrude into my trains of thought. |
2597 | Contrary to the 'anomalous monist' view, there may well be intentional causal laws [Fodor] |
Full Idea: I argue that (contrary to the doctrine called "anomalous monism") there is no good reason to doubt that there are intentional causal laws. | |
From: Jerry A. Fodor (Making Mind Matter More [1989], p.151) | |
A reaction: I certainly can't see a good argument, in Davidson or anywhere else, to demonstrate their impossibility. Give the complexity of the brain, they would be like the 'laws' for weather or geology. |
2985 | Are beliefs brains states, but picked out at a "higher level"? [Lyons on Fodor] |
Full Idea: Fodor holds that beliefs are brain states or processes, but picked out at a 'higher' or 'special science' level. | |
From: comment on Jerry A. Fodor (works [1986]) by William Lyons - Approaches to Intentionality p.82 | |
A reaction: I don't think you can argue with this. Levels of physical description exist (e.g. pure physics tells you nothing about the weather), and I think 'process' is the best word for the mind (Idea 4931). |
2489 | Why bother with neurons? You don't explain bird flight by examining feathers [Fodor] |
Full Idea: Compare Churchland's strategy rooted in neurological modelling with "if it's flight you want to understand, what you need to look at is feathers". | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 8) | |
A reaction: Sounds good, but may be a false analogy. You learn a lot about snake movement if you examine their scales. |
2995 | Supervenience gives good support for mental causation [Fodor] |
Full Idea: Mind/brain supervenience is the best idea anyone has had so far about how mental causation is possible. | |
From: Jerry A. Fodor (Psychosemantics [1987], p. 30) | |
A reaction: I would have thought that mind brain identity was a much better idea (see Idea 3440). Supervenience seems to prove that 'mental causation' occurs, but doesn't explain it. |
2464 | Type physicalism equates mental kinds with physical kinds [Fodor] |
Full Idea: Type physicalism is, roughly, the doctrine that psychological kinds are identical to neurological kinds. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], App A n.1) | |
A reaction: This gets my general support, leaving open the nature of 'kinds'. Presumably the identity is strict, as in 'Hesperus is identical to Phosphorus'. It seems unlikely that if you and I think the 'same' thought, that we have strictly identical brain states. |
2468 | Type physicalism is a stronger claim than token physicalism [Fodor] |
Full Idea: "Type" physicalism is supposed, by general consensus, to be stronger than "token" physicalism; stronger, that is, than the mere claim that all mental states are necessarily physically instantiated. | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 2) | |
A reaction: Such philosopher's terminology always seems cut-and-dried, until you ask exactly what is identical to what. The word 'type' is a very broad concept. Are trees the same type of thing as roses? A thought always requires the same 'type' of brain event? |
2447 | Hume has no theory of the co-ordination of the mind [Fodor] |
Full Idea: What Hume didn't see was that the causal and representational properties of mental symbols have somehow to be coordinated if the coherence of mental life is to be accounted for. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §4) | |
A reaction: Certainly the idea that it all somehow becomes magic at the point where the brain represents the world is incoherent - but it is a bit magical. How can the whole of my garden be in my brain? Weird. |
2490 | Modern connectionism is just Hume's theory of the 'association' of 'ideas' [Fodor] |
Full Idea: Churchland is pushing a version of connectionism ….in which if you think of the elements as "ideas" and call the connections between them "associations", you've got a psychology that is no great advance on David Hume. | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 8) | |
A reaction: See Fodor's book 'Humean Variations' on how Hume should be improved. This idea strikes me as important for understanding Hume, who is very reticent about what his real views are on the mind. |
12624 | Only the labels of nodes have semantic content in connectionism, and they play no role [Fodor] |
Full Idea: Connectionism has no truck with mental representations; on the one hand, only the node labels in 'neural networks' have semantic content, and, on the other, the node labels play no role in mental processes, in standard formulations. | |
From: Jerry A. Fodor (LOT 2 [2008], Ch.1) | |
A reaction: Connectionism must have some truth in it, yet mere connections can't do the full job. The difficulty is that nothing else seems to do the 'full job' either. Fodor cites productivity, systematicity, compositionality, logical form as the problems. |
2991 | Hume's associationism offers no explanation at all of rational thought [Fodor] |
Full Idea: With Associationism there proved to be no way to get a rational mental life to emerge from the sorts of causal relations among thoughts that the 'laws of association' recognised. | |
From: Jerry A. Fodor (Psychosemantics [1987], p. 18) | |
A reaction: This might not be true if you add the concept of evolution, which has refined the associations to generate truth (which is vital for survival). |
3002 | If mind is just physical, how can it follow the rules required for intelligent thought? [Fodor] |
Full Idea: Central state identity theorists had trouble providing for the nomological possibility of rational machines (and hence no space for a non-biological, e.g. computational, theory of intelligence). | |
From: Jerry A. Fodor (Psychosemantics [1987], p. 67) | |
A reaction: I surmise that a more externalist account of the physical mind might do the trick, by explaining intelligence in terms of an evolved relationship between brain and environment. |
2598 | Lots of physical properties are multiply realisable, so why shouldn't beliefs be? [Fodor] |
Full Idea: If one of your reasons for doubting that believing-that-P is a physical property is that believing is multiply realizable, then you have the same reason for doubting that being an airfoil (or a mountain) counts as a physical property. | |
From: Jerry A. Fodor (Making Mind Matter More [1989], p.153) | |
A reaction: This merely points out that functionalism is not incompatible with physicalism, which must be right. |
3981 | Most psychological properties seem to be multiply realisable [Fodor] |
Full Idea: These days most philosophers of mind suppose that most psychological properties are multiply realisable. | |
From: Jerry A. Fodor (Jerry A. Fodor on himself [1994], p.298) | |
A reaction: This is just speculation. The physical part may seem very different, but turn out to be identical in the ways that matter (like a knife made of two different metals). |
12641 | Connectionism gives no account of how constituents make complex concepts [Fodor] |
Full Idea: Connectionist architectures provide no counterpart to the relation between a complex concept and its constituents. | |
From: Jerry A. Fodor (LOT 2 [2008], Ch.3.3 n29) | |
A reaction: This is the compositionality of thought, upon which Fodor is so insistent. Not that a theory of how the mind is built up from the body is quite likely to give you a theory about what thinking is. I try to keep them separate, which may be wrong. |
2992 | We may be able to explain rationality mechanically [Fodor] |
Full Idea: We are on the verge of solving a great mystery about the mind: how is rationality mechanically possible? | |
From: Jerry A. Fodor (Psychosemantics [1987], p. 20) | |
A reaction: Optimistic, given that AI has struggled to implement natural languages, mainly because common sense knowledge seems too complex to encode. Can a machine determine logical forms of sentences? |
2476 | The goal of thought is to understand the world, not instantly sort it into conceptual categories [Fodor] |
Full Idea: The question whether there are recognitional concepts is really the question what thought is for - for directing action, or for discerning truth. And Descartes was right on this: the goal of thought is to understand the world, not to sort it. | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 4) |
12640 | Associative thinking avoids syntax, but can't preserve sense, reference or truth [Fodor] |
Full Idea: The virtue of associative theories of thinking is that they don't require thoughts to have syntactic structure. But they can't be right, since association doesn't preserve either sense or reference (to say nothing of truth). | |
From: Jerry A. Fodor (LOT 2 [2008], Ch.3.3 n28) | |
A reaction: This is using the empiricist idea that knowledge is built from mechanical associations to give a complete account of what thinking is. Fodor resolutely opposes it. |
2440 | Propositional attitudes are propositions presented in a certain way [Fodor] |
Full Idea: Propositional attitudes are really three-place relations, between a creature, a proposition, and a mode of presentation (which are sentences of Mentalese). | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §2.II) | |
A reaction: I'm not sure about 'really'! Why do we need a creature? Isn't 'hoping it will rain' a propositional attitude which some creature may or may not have? Fodor wants it to be physical, but it's abstract? |
2988 | Folk psychology is the only explanation of behaviour we have [Fodor] |
Full Idea: Commonsense belief/desire psychology explains vastly more of the facts about behaviour than any of the alternative theories available. It could hardly fail to; there are no alternative theories available. | |
From: Jerry A. Fodor (Psychosemantics [1987], p.x) | |
A reaction: The alternative view wouldn't expect a clear-cut theory, because it deals with the endless complexity of brain events. The charge is that Fodor and co oversimplify their account, in their desperation for a 'theory'. |
3975 | Folk psychology explains behaviour by reference to intentional states like belief and desire [Fodor] |
Full Idea: Folk psychology is primarily intentional explanation; it's the idea that people's behaviour can be explained by reference to the contents of their beliefs and desires. | |
From: Jerry A. Fodor (Jerry A. Fodor on himself [1994], p.292) | |
A reaction: Sounds good. To reject folk psychology (as reductivists tend to) is to reject the existence of significant intentional states which have causal properties |
2450 | Rationality has mental properties - autonomy, productivity, experiment [Fodor] |
Full Idea: Mentalism isn't gratuitous; you need it to explain rationality. Mental causation buys you behaviours that are unlike reflexes in at least three ways: they're autonomous, they're productive, and they're experimental. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §4) | |
A reaction: He makes his three ways sound all-or-nothing, which is (I believe) the single biggest danger when thinking about the mind. "Either you are conscious, or you are not..." |
22108 | First grasp what it is, then its essential features; judgement is their compounding and division [Aquinas] |
Full Idea: The intellect first apprehends the quiddity of a thing. ...Then it acquires the properties, accidents and dispositions associated with the thing's essence. It must proceed from one compounding or dividing of aspects to another, which is reasoning. | |
From: Thomas Aquinas (Summa Theologicae [1265], Ia.Q85 5c), quoted by Kretzmann/Stump - Aquinas, Thomas 11 | |
A reaction: [compressed] Tracking the process of acquiring knowledge of a thing (rather than necessary and sufficient conditions for full knowledge) is closer to Quine's naturalised epistemology than to the standard analytic approach to the concept of knowledge. |
18424 | If two people can have phenomenally identical experiences, they can't involve the self [Brogaard] |
Full Idea: It is plausible that you and I can have perceptual experiences with the same phenomenology of two trees at different distances from us (perhaps at different times). ..So our perceptual experiences cannot contain you or me in the content of representation. | |
From: Berit Brogaard (Perceptual Content and Monadic Truth [2009], p.223), quoted by Cappelen,H/Dever,Josh - The Inessential Indexical 08.2 | |
A reaction: If you accept the example, which seems reasonable, then that pretty conclusively shows that perception is not inherently indexical. |
22186 | Mental modules are specialised, automatic, and isolated [Fodor, by Okasha] |
Full Idea: Fodor argues that mental modules have three important featuresL 1) they are domain-specific, 2) their operation is mandatory, 3) they are informationally encapsulated. | |
From: report of Jerry A. Fodor (The Modularity of Mind [1983]) by Samir Okasha - Philosophy of Science: Very Short Intro (2nd ed) 6 | |
A reaction: Mandatory is interesting. When I hear an English sentence I can't decide not to process it. Modules cannot be too isolated or they couldn't participate in the team. Each one needs a comms manager. |
2491 | Modules have encapsulation, inaccessibility, private concepts, innateness [Fodor] |
Full Idea: The four essential properties of modules are: encapsulation (information doesn't flow, as in the persistence of illusions); inaccessibility (unreportable); domain specificity (they have private concepts); innateness (genetically preprogrammed). | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch.11) | |
A reaction: If they have no information flow, and are unreportable and private, this makes empirical testing of Fodor's hypothesis a little tricky. He must be on to something, though. |
2497 | Something must take an overview of the modules [Fodor] |
Full Idea: It is not plausible that the mind could be made only of modules; one does sometimes manage to balance one's checkbook, and there can't be an innate, specialized intelligence for doing that. | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch.13) | |
A reaction: I agree strongly with this. My own mind strikes me as being highly modular, but as long as I am aware of the output of the modules, I can pass judgement. The judger is more than a 'module'. |
2495 | Obvious modules are language and commonsense explanation [Fodor] |
Full Idea: The best candidates for the status of mental modules are language (the first one, put there by Chomsky), commonsense biology, commonsense physics, commonsense psychology, and aspects of visual form perception. | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch.13) | |
A reaction: My favourite higher level module is my Personal Assistant, who keeps nagging me to do sundry things, only some of which I agree to. It is an innate superego, but still a servant of the Self. |
2499 | Modules analyse stimuli, they don't tell you what to do [Fodor] |
Full Idea: The thinking involved in "figuring out" what to do is a quite different kind of mental process than the stimulus analysis that modules perform. | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch.13) | |
A reaction: My PA theory fits this perfectly. My inner assistant keeps providing information about needs, duties etc., but takes no part in my decisions. Psychology must include the Will. |
2509 | Modules have in-built specialist information [Fodor] |
Full Idea: Modules contain lots of specialized information about the problem domains that they compute in. | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch.17) | |
A reaction: At this point we must be cautious about modularity. I doubt whether 'information' is the right word. I think 'specialized procedures' might make more sense. |
2496 | Blindness doesn't destroy spatial concepts [Fodor] |
Full Idea: Blind children are not, in general, linguistically impaired; not even in their talk about space. | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch.13) | |
A reaction: This is offered to demonstrate that spatial concepts are innate, even in the blind. But then we would expect anyone who has to move in space to develop spatial concepts from experience. |
2507 | Rationality rises above modules [Fodor] |
Full Idea: Probably, modular computation doesn't explain how minds are rational; it's just a sort of precursor. You work through it to get a view of how horribly hard our rationality is to understand. | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch.17) | |
A reaction: The choice is between a Self which weighs and judges the inputs, or merely decisions that automatically result from the balance of inputs. The latter seems unlikely. Vetoes are essential. |
2500 | Babies talk in consistent patterns [Fodor] |
Full Idea: "Who Mummy love?" is recognizably baby talk; but "love Mummy who?" is not. | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch.14) | |
A reaction: Not convincing. If she is embracing Daddy, and asking baby, she might get the answer "Daddy", after a bit of coaxing. Who knows what babies up the Amazon respond to? |
2498 | Modules make the world manageable [Fodor] |
Full Idea: Modules function to present the world to thought under descriptions that are germane to the success of behaviour. | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch.13) | |
A reaction: "Descriptions" might be a bold word to use about something so obscure, but this pinpoints the evolutionary nature of modularity theory, to which I subscribe. |
2483 | Mentalese doesn't require a theory of meaning [Fodor] |
Full Idea: Mentalese doesn't need Grice's theory of natural-language meaning, or indeed any theory of natural-language meaning whatsoever. | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 6) | |
A reaction: Presumably what is represented by mentalese is a quite separate question from whether there exists a mentalese that does some sort of representing. Sounds plausible. |
2487 | Mentalese may also incorporate some natural language [Fodor] |
Full Idea: I don't think it is true that all thought is in Mentalese. It is quite likely (e.g. in arithmetic algorithms) that Mentalese co-opts bits of natural language. | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 6) | |
A reaction: Presumably language itself would have to be coded in mentalese. If there is some other way for thought to work, the whole mind could use it, and skip mentalese. |
2480 | Language is ambiguous, but thought isn't [Fodor] |
Full Idea: Thinking can't just be in sequences of English words since, notoriously, thought needs to be ambiguity-free in ways that mere word sequences are not. | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 6) | |
A reaction: I think this is a strong argument in favour of (at least) propositions. Thoughts are unambiguous, but their expression need not be. Sentences could be expanded to achieve clarity. |
12643 | Ambiguities in English are the classic reason for claiming that we don't think in English [Fodor] |
Full Idea: That there are ambiguities in English is the classic reason for claiming that we don't think in English. | |
From: Jerry A. Fodor (LOT 2 [2008], Ch.3.5) | |
A reaction: I have always been impressed by this simple observation, which is my main reason for believing in propositions (as brain events). 'Propositions' may just be useful chunks of mentalese. |
8090 | Since the language of thought is the same for all, it must be something like logical form [Fodor, by Devlin] |
Full Idea: Fodor and Jackendorff argue that since the internal language of thought, or conceptual structure, has to be more or less the same for all people, of whatever language, it will surely be something like logical form. | |
From: report of Jerry A. Fodor (The Language of Thought [1975]) by Keith Devlin - Goodbye Descartes Ch.8 | |
A reaction: The discovery (by, e.g., Frege and Russell) that there is something called 'logical form', which we can track down and represent in precise and fairly unambiguous symbolism, may be one of the greatest of all human discoveries. Perhaps. |
3010 | Belief and desire are structured states, which need mentalese [Fodor] |
Full Idea: A defence of the language of thought has to be an argument that believing and desiring are typically structured states. | |
From: Jerry A. Fodor (Psychosemantics [1987], p.136) | |
A reaction: A structure is one thing, and a language is another. Both believings and desirings can be extremely vague, to the point where the owner is unsure what is believed or desired. They can, of course, be extremely precise. |
2604 | We must have expressive power BEFORE we learn language [Fodor] |
Full Idea: I am denying that one can learn a language whose expressive power is greater than that of a language that one already knows. | |
From: Jerry A. Fodor (How there could be a private language [1975], p.389) | |
A reaction: I presume someone who had a native language of limited vocabulary could learn a new language with a vast vocabulary. I can increase my expressive power with a specialist vocabulary (e.g. legal). |
12647 | Mental representations name things in the world, but also files in our memory [Fodor] |
Full Idea: Mental representations can serve both as names for things in the world and as names of files in the memory. | |
From: Jerry A. Fodor (LOT 2 [2008], Ch.3 App) | |
A reaction: I am laughed at for liking this idea (given the present files of ideas before you), but I think this it is very powerful. Chicken before egg. I was drawn to databases precisely because they seemed to map how the mind worked. |
12649 | We think in file names [Fodor] |
Full Idea: We think in file names. | |
From: Jerry A. Fodor (LOT 2 [2008], Ch.3 App) | |
A reaction: This is Fodor's new view. He cites Treisman and Schmidt (1982) for raising it, and Pylyshyn (2003) for discussing it. I love it. It exactly fits my introspective view of how I think, and I think it would fit animals. It might not fit some other people! |
3135 | Is thought a syntactic computation using representations? [Fodor, by Rey] |
Full Idea: The modest mentalism of the Computational/Representational Theory of Thought (CRTT), associated with Fodor, says mental processes are computational, defined over syntactically specified entities, and these entities represent the world (are also semantic). | |
From: report of Jerry A. Fodor (works [1986]) by Georges Rey - Contemporary Philosophy of Mind Int.3 | |
A reaction: This seems to imply that if you built a machine that did all these things, it would become conscious, which sounds unlikely. Do footprints 'represent' feet, or does representation need prior consciousness? |
12655 | Frame Problem: how to eliminate most beliefs as irrelevant, without searching them? [Fodor] |
Full Idea: The frame problem is, precisely: How does one know that none of one's beliefs about Jupiter are germane to the current question, without having to recall and search one's beliefs about Jupiter? | |
From: Jerry A. Fodor (LOT 2 [2008], Ch.4.4) | |
A reaction: Presumably good chess-playing computers have made some progress with this problem. The only answer, as far as I can see, is that brains have a lot in common with relational databases. The mind is structured around a relevance-pattern. |
2983 | Maybe narrow content is physical, broad content less so [Lyons on Fodor] |
Full Idea: Fodor is concerned with producing a realist and physicalist account of 'narrow content' (i.e. wholly in-the-head content). | |
From: comment on Jerry A. Fodor (works [1986]) by William Lyons - Approaches to Intentionality p.54 | |
A reaction: The emergence of 'wide' content has rather shaken Fodor's game plan. We can say "Oh dear, I thought I was referring to H2O", so there must be at least some narrow aspect to reference. |
12615 | Mental representations are the old 'Ideas', but without images [Fodor] |
Full Idea: The idea that there are mental representations is the idea that there are Ideas minus the idea that Ideas are images. | |
From: Jerry A. Fodor (Concepts:where cogn.science went wrong [1998], Ch.1) | |
A reaction: Good for you, Fodor. I've always thought that the vociferous contempt with which modern philosphers refer to the old notion of 'Ideas' was grossly exaggerated. At last someone puts a clear finger on what seems to be the difficulty. |
2437 | XYZ (Twin Earth 'water') is an impossibility [Fodor] |
Full Idea: There isn't any XYZ, and there couldn't be any, and so we don't have to worry about it. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §2.I) | |
A reaction: Jadeite and Nephrite are real enough, which are virtually indistinguishable variants of jade. You just need Twin Jewellers instead of Twin Earths. We could build them, and employ twins to work there. |
12630 | If concept content is reference, then my Twin and I are referring to the same stuff [Fodor] |
Full Idea: If the content of a concept is its reference, we can stop worrying about Twin Earth. If there are no senses, there is no question of whether my twin and I have the same WATER concept. Our WATER concepts aren't even coextensive. | |
From: Jerry A. Fodor (LOT 2 [2008], Ch.1) | |
A reaction: This seems like a neat solution. So do 'tap water' and 'holy water' have the same content to a Christian and non-Christian, when they co-refer to the contents of the font? |
3982 | How could the extrinsic properties of thoughts supervene on their intrinsic properties? [Fodor] |
Full Idea: It is hard to see how the extrinsic properties of thoughts could supervene on their intrinsic properties. | |
From: Jerry A. Fodor (Jerry A. Fodor on himself [1994], p.299) | |
A reaction: This doesn't seem a big problem. Sometimes represented experiences establish the match; sometimes the match is not very good, or even wrong. |
2441 | Truth conditions require a broad concept of content [Fodor] |
Full Idea: We need the idea of broad content to make sense of the fact that thoughts have the truth-conditions that they do. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §2.II) | |
A reaction: There seems to be (as Dummett points out) a potential circularity here, as you can hardly know the truth-conditions of something if you don't already know its content. |
2999 | Obsession with narrow content leads to various sorts of hopeless anti-realism [Fodor] |
Full Idea: People who ask what the narrow content of the thought that water is wet is (for example) get what they deserve: phenomenalism, verificationism, 'procedural' semantics, or scepticism, according to temperament. | |
From: Jerry A. Fodor (Psychosemantics [1987], p. 51) | |
A reaction: The question is whether content IS narrow. We could opt for broad content because then we wouldn't have to worry about scepticism, but I doubt whether we would then sleep well at night. |
3114 | Concepts aren't linked to stuff; they are what is caused by stuff [Fodor] |
Full Idea: If the words of 'Swamp Man' (spontaneously created, with concepts) are about XYZ on Twin Earth, it is not because he's causally connected to the stuff, but because XYZ would cause his 'water' tokens (in the absence of H2O). | |
From: Jerry A. Fodor (The Elm and the Expert [1993], App B) | |
A reaction: The sight of the Eiffel tower causes my 'France' tokens, so is my word "France" about the Eiffel Tower? What would cause my 'nothing' tokens? |
2486 | Content can't be causal role, because causal role is decided by content [Fodor] |
Full Idea: Functional role semantics wants to analyze the content of a belief in terms of its inferential (causal) relations; but that seems the wrong way round. The content of a belief determines its causal role. | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 6) | |
A reaction: This is one of my favourite ideas, which keeps coming to mind when considering functional accounts of mental life. The buck of explanation must, however, stop somewhere. |
3012 | Do identical thoughts have identical causal roles? [Fodor] |
Full Idea: If thoughts have their causal roles in virtue of their contents, then two thoughts with identical contents ought to be identical in their causal roles. | |
From: Jerry A. Fodor (Psychosemantics [1987], p.140) | |
A reaction: A pencil would presumably have the same causal role if it wrote a love poem or hate mail. But a pencil is also good for scratching your back. 'Causal role' can be a rather vacuous idea. |
2452 | Knowing the cause of a thought is almost knowing its content [Fodor] |
Full Idea: If you know the content of a thought, you know quite a lot about what would cause you to have it. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §4) | |
A reaction: I'm not sure where this fits into the great jigsaw of the mind, but it strikes me as an acute and important observation. The truth of a thought is not essential to make you have it. Ask Othello. |
2432 | Is content basically information, fixed externally? [Fodor] |
Full Idea: I assume intentional content reduces (in some way) to information. …The content of a thought depends on its external relations; on the way that the thought is related to the world, not the way that it is related to other thoughts. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §1.2) | |
A reaction: Does this make Fodor a 'weak' functionalist? The 'strong' version would say a thought is merely a location in a flow diagram, but Fodor's 'mentalism' includes a further 'content' in each diagram box. |
12658 | Nobody knows how concepts are acquired [Fodor] |
Full Idea: I don't know how concepts are acquired. Nor do you. Nor does anybody else. | |
From: Jerry A. Fodor (LOT 2 [2008], Ch.5.4) | |
A reaction: This comes in the context of quietly modifying his earlier claim that concepts weren't acquired, because they were largely innate. Presumably we are allowed to have theories of concept acquisition? I quite like abstractionism. |
2492 | Experience can't explain itself; the concepts needed must originate outside experience [Fodor] |
Full Idea: Experience can't explain itself; eventually, some of the concepts that explaining experience requires have to come from outside it. Eventually, some of them have to be built in. | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch.12) |
11143 | If concept-learning is hypothesis-testing, that needs innate concepts to get started [Fodor, by Margolis/Laurence] |
Full Idea: Fodor argues that virtually all lexical concepts are innate, because most models of learning treat concept-learning as hypothesis testing, but that invariably employs the very concept to be learned. | |
From: report of Jerry A. Fodor (The Language of Thought [1975]) by E Margolis/S Laurence - Concepts 3.3 | |
A reaction: The obvious response is to reject the theory which gave rise to this difficulty. I take concept formation to be a fairly mechanical and barely conscious response to environment, not a process of fully rational and conscious hypothesising. |
6650 | Fodor is now less keen on the innateness of concepts [Fodor, by Lowe] |
Full Idea: Fodor has recently changed his mind about the innateness of concepts, which he formerly championed. | |
From: report of Jerry A. Fodor (Concepts:where cogn.science went wrong [1998]) by E.J. Lowe - Introduction to the Philosophy of Mind Ch.7 n25 | |
A reaction: There is some sensible middle road to be charted here. We presumably do not have an innate idea of a screwdriver, but there are plenty of basic concepts in logic and perception that are plausibly thought of as innate. |
12662 | We have an innate capacity to form a concept, once we have grasped the stereotype [Fodor] |
Full Idea: What's learned are stereotypes. What's innate is the disposition to grasp such and such a concept (to lock to such a property) in consequence of having learned such and such a stereotype. | |
From: Jerry A. Fodor (LOT 2 [2008], Ch.5.4) | |
A reaction: This is the late Fodor much ameliorated view, after a lot of scoffing about the idea of the tin-opener being innate in all of us. There may be a suspicion of circularity here, if we ask what mental abilities are needed to form a stereotype. |
12618 | It is essential to the concept CAT that it be satisfied by cats [Fodor] |
Full Idea: Nothing in any mental life could be the concept CAT unless it is satisfied by cats. If you haven't got a concept that applies to cats, that entails that you haven't got the CAT concept. | |
From: Jerry A. Fodor (Concepts:where cogn.science went wrong [1998], Ch.2) | |
A reaction: Of course, having a concept that applies to cats doesn't entail that you have the CAT concept. Quine's 'gavagai', for example. I think Fodor is right in this idea. |
12635 | Having a concept isn't a pragmatic matter, but being able to think about the concept [Fodor] |
Full Idea: Pragmatism about concepts really is dead, and the only alternative about concept possession is Cartesianism. That is, it's the thesis that having concept C is being able to think about Cs (as such). | |
From: Jerry A. Fodor (LOT 2 [2008], Ch.2.2) | |
A reaction: I like this. It is very hard to pick out from Fodor the bits where he is clearly right, but this seems to be one of them. I don't like the pragmatic or Wittgensteinian line that having concepts is all about abilities and uses (like sorting or inferring). |
12652 | Concepts have two sides; they are files that face thought, and also face subject-matter [Fodor] |
Full Idea: We think in file names, and file names are Janus-faced: one face turned towards thinking and the other face turned towards what is thought about. I do think that is rather satisfactory. | |
From: Jerry A. Fodor (LOT 2 [2008], Ch.3 App) | |
A reaction: So do I. I do hope the philosophical community take up this idea (which they probably won't, simply because Fodor is in the late stages of his career!). |
2438 | In the information view, concepts are potentials for making distinctions [Fodor] |
Full Idea: Semantics, according to the informational view, is mostly about counterfactuals; what counts for the identity of my concepts is not what I do distinguish but what I could distinguish if I cared to (even using instruments and experts). | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §2.I) | |
A reaction: We all differ in our discriminations (and awareness of expertise), so our concepts would differ, which is bad news for communication (see Idea 223). The view has some plausibility, though. |
12614 | I prefer psychological atomism - that concepts are independent of epistemic capacities [Fodor] |
Full Idea: I argue for a very strong version of psychological atomism; one according to which what concepts you have is conceptually and metaphysically independent of what epistemic capacities you have. | |
From: Jerry A. Fodor (Concepts:where cogn.science went wrong [1998], Ch.1) | |
A reaction: This is a frontal assault on the tradition of Frege, Dummett and Peacocke. I immediately find Fodor's approach more congenial, because he wants to say what a concept IS, rather than just place it within some larger scheme of things. |
2471 | Are concepts best seen as capacities? [Fodor] |
Full Idea: Virtually all modern theorists about philosophy, mind or language tend to agree that concepts are capacities, in particular concepts are epistemic capacities. | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 3) | |
A reaction: This view seems to describe concepts in functional terms, which generates my perennial question: what is it about concepts that enables them to fulfil that particular role? |
2472 | For Pragmatists having a concept means being able to do something [Fodor] |
Full Idea: It's a paradigmatically Pragmatist idea that having a concept consists in being able to do something. | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 3) | |
A reaction: If you defined a bicycle simply by what you could do with it, you wouldn't explain much. I wonder if pragmatism and functionalism come from the same intellectual stable? |
12626 | Cartesians put concept individuation before concept possession [Fodor] |
Full Idea: Cartesians think that concept individuation is prior, in order of analysis, to concept possession. | |
From: Jerry A. Fodor (LOT 2 [2008], Ch.12) | |
A reaction: Peacocke is someone who seems to put possession first, to the point where individuation is thereby achieved. The background influence there is Wittgenstein. I think I am more with Fodor, that concepts are entities, which need to be understood. |
12637 | Frege's puzzles suggest to many that concepts have sense as well as reference [Fodor] |
Full Idea: Philosophers in droves have held that Frege cases are convincing arguments that concepts have not just referents but also senses. | |
From: Jerry A. Fodor (LOT 2 [2008], Ch.3.2) | |
A reaction: [Frege cases are puzzles where simple reference seems to lead to confusion] I take the Fregean approach to concepts (of Dummett, Peacocke) to attempt to give an account of the sense, once the reference is decided. Idea 12629 gives Fodor's view. |
12638 | If concepts have sense, we can't see the connection to their causal powers [Fodor] |
Full Idea: How are we to understand the connection between the identity of a concept and its causal powers if concepts are (or have) senses? Answer: I haven't a clue. | |
From: Jerry A. Fodor (LOT 2 [2008], Ch.3.3) | |
A reaction: This seems to be the key to Fodor's attack on Peacocke and other Fregeans - that while they pay lip-service to the project of naturalising thought, they are actually committing us to some sort of neo-platonism, by losing the causal links. See Idea 12636. |
12639 | Belief in 'senses' may explain intentionality, but not mental processes [Fodor] |
Full Idea: Supposing the mind to be conversant with senses can, maybe, provide for a theory of the intentionality of mental states; but it seems to shed no light at all on the nature of mental processes (i.e. of mental state transitions). | |
From: Jerry A. Fodor (LOT 2 [2008], Ch.3.3) | |
A reaction: I would track this back to Frege's hostility to 'psychologism'. That is, Fregeans don't care about Fodor's problem, because all their accounts (of mathematics, of logic, and of concepts) treat the subject-matter as self-contained sui generis. |
12654 | You can't think 'brown dog' without thinking 'brown' and 'dog' [Fodor] |
Full Idea: You can think 'brown dog' without thinking 'cat', but you can't think 'brown dog' without thinking 'brown' and 'dog'. | |
From: Jerry A. Fodor (LOT 2 [2008], Ch.4.3) | |
A reaction: Fodor is talking about concepts in thought, not about words. The claim is that such concepts have to be compositional, and it is hard to disagree. |
12621 | Definable concepts have constituents, which are necessary, individuate them, and demonstrate possession [Fodor] |
Full Idea: The definition theory says that concepts are complex structures which entail their constituents. By saying this, it guarantees both the connection between content and necessity, and the connection between concept individuation and concept possession. | |
From: Jerry A. Fodor (Concepts:where cogn.science went wrong [1998], Ch.5) | |
A reaction: He cites Pinker as a spokesman for the definitional view. This is the view Fodor attacks, in favour of his atomistic account. He adds in a note that his view also offered to reduce conceptual truth to logical truth. |
12622 | Many concepts lack prototypes, and complex prototypes aren't built from simple ones [Fodor] |
Full Idea: Many concepts have no prototypes; and there are many complex concepts whose prototypes aren't related to the prototypes of their constituents in the way compositional explanation of productivity and systematicity requires. | |
From: Jerry A. Fodor (Concepts:where cogn.science went wrong [1998], Ch.5) | |
A reaction: His favourite example of the latter is 'pet fish', where the prototype of 'pet' is hardly ever a fish, and the prototype of 'fish' is usually much bigger than goldfish. Fodor is arguing that concepts are atomic. |
12659 | Maybe stereotypes are a stage in concept acquisition (rather than a by-product) [Fodor] |
Full Idea: We needn't say that learning a stereotype is just a by-product of acquiring the concept; it could rather be a stage in concept acquisition. | |
From: Jerry A. Fodor (LOT 2 [2008], Ch.5.4) | |
A reaction: He rejects stereotypes because they don't give concepts the necessary compositionality in thought. But this idea would mean that children were incapable of compositionality until they had transcended the primitive stereotype stage. |
12660 | One stereotype might be a paradigm for two difference concepts [Fodor] |
Full Idea: The same stereotype can give difference concepts; chickens are paradigmatic instances both of FOOD and of BARNYARD FOWL. | |
From: Jerry A. Fodor (LOT 2 [2008], Ch.5.4) | |
A reaction: And I'm guessing that lots of concepts could have two equally plausible stereotypes, even within a single mind. Stereotypes are interesting, but they don't seem to be the key to our understanding of concepts. |
12623 | The theory theory can't actually tell us what concepts are [Fodor] |
Full Idea: If the theory theory has a distinctive and coherent answer to the 'What's a concept?' question on offer, it's a well-kept secret. | |
From: Jerry A. Fodor (Concepts:where cogn.science went wrong [1998], Ch.5) | |
A reaction: Not an argument, but worth recording as an attitude. I certainly agree that accounts which offer some sort of answer to 'What is a concept?' have an immediate head's start on those which don't. |
12629 | For the referential view of thought, the content of a concept is just its reference [Fodor] |
Full Idea: Pure referentialism is the kind of semantics RTM requires (reference is the only primitive mind-world semantic property). ...So the content of a concept is its reference. | |
From: Jerry A. Fodor (LOT 2 [2008], Ch.1) | |
A reaction: This seems to say that the meaning of a concept is (typically) a physical object, which seems to be the 'Fido'-Fido view of meaning. It seems to me to be a category mistake to say that a meaning can be a cat. |
12631 | Compositionality requires that concepts be atomic [Fodor] |
Full Idea: Atomism must be right about the individuation of concepts because compositionality demands it. | |
From: Jerry A. Fodor (LOT 2 [2008], Ch1) | |
A reaction: I suppose this seems right, though Fodor's own example of 'pet fish' is interesting. What is supposed to happen when you take a concept like 'pet' and put it with 'fish', given that both components shift their atomic (?) meaning in the process? |
10503 | We abstract forms from appearances, and acquire knowledge of immaterial things [Aquinas] |
Full Idea: To cognize that which is in individual matter, not as it is in such matter, is to abstract the form from the individual matter that the phantasms represents. Thus we come to a degree of cognition of immaterial things. | |
From: Thomas Aquinas (Summa Theologicae [1265], Q85 1 Reply) | |
A reaction: This offers abstraction as a kind of inference to best explanation which takes us beyond immediate empirical experience to what is behind it. Aquinas thinks the concepts and explanation are spiritual, but they may be generalities and essences. |
10509 | Understanding consists entirely of grasping abstracted species [Aquinas] |
Full Idea: Of the thing understood all that is within the actually understanding intellect is the abstracted intelligible species. | |
From: Thomas Aquinas (Summa Theologicae [1265], Q85 Art2) | |
A reaction: Abstraction is never supposed to be a luxury bolt-on, but is always seen (in this tradition, and presumably in the modern one), as essential to the intellect, and its way of coming to understand the world. Aristotelian definition is behind this idea. |
10506 | Mathematics can be abstracted from sensible matter, and from individual intelligible matter [Aquinas] |
Full Idea: Intellect can abstract mathematical species from sensible matter, both individual and common. Yet it cannot abstract such species from common intelligible matter, but only from individual intelligible matter. | |
From: Thomas Aquinas (Summa Theologicae [1265], Q85 Ad2) | |
A reaction: The idea is that common intelligible matter lacks underlying substance, which is where quantity is to be found. |
12657 | Abstractionism claims that instances provide criteria for what is shared [Fodor] |
Full Idea: In the idea of learning concepts by 'abstraction', experiences of the instances provide evidence about which of the shared properties of things in a concept's extension are 'criterial' for being in the concept's extension. | |
From: Jerry A. Fodor (LOT 2 [2008], Ch.5.2 n6) | |
A reaction: Fodor is fairly sceptical of this approach, and his doubts are seen in the scare-quotes around 'criterial'. He is defending the idea that only a certain degree of innateness in the concepts can get such a procedure off the ground. |
9094 | Mathematical objects abstract both from perceived matter, and from particular substance [Aquinas] |
Full Idea: Objects of mathematics abstract from perceived matter both in particular and in general, though from thought matter (substance as underlying quality) only in particular and not in general. | |
From: Thomas Aquinas (Summa Theologicae [1265], Ch.5 Q85.1) | |
A reaction: This appears to be a thoroughly abstractionist view of the way in which humans create mathematics. Aquinas explicitly denies the Platonic view that the numbers already have abstract existence, awaiting our discovery. |
10505 | We can just think of an apple's colour, because the apple is not part of the colour's nature [Aquinas] |
Full Idea: The apple is not part of the nature of the colour, and so nothing prevents one from understanding the colour while understanding nothing of the apple. | |
From: Thomas Aquinas (Summa Theologicae [1265], Q85 1 Ad 1) | |
A reaction: This helps to clarify why the procedure of 'ignoring' features is possible. It suggests that some features might be too entangled with the substance (too essential?) to be thus ignored. I can't think of an example, though. Why not?! |
10504 | Abstracting either treats something as separate, or thinks of it separately [Aquinas] |
Full Idea: Abstracting takes place in two ways: by composition and division, understanding something to be not in another or to be separated from it; and by a simple and unconditioned consideration, understanding one thing while not considering the other at all. | |
From: Thomas Aquinas (Summa Theologicae [1265], Q85 1 Ad 1) | |
A reaction: The second way is by 'ignoring', which he says cannot contain error. The first seems to be considering some mode of a thing to be actually separate from the thing, which could clearly be erroneous. Ignoring makes to commitment to a unity. |
10507 | Numbers and shapes are abstracted by ignoring their sensible qualities [Aquinas] |
Full Idea: Quantities such as numbers and dimensions, and also shapes (which are the limits of quantities) can be considered without their sensible qualities, which is for them to be abstracted from sensible matter. | |
From: Thomas Aquinas (Summa Theologicae [1265], Q85 Ad2) | |
A reaction: His account relies on underlying substance, which is where quantity is to be found (presumably because a substance is the epitome of a unit). |
9096 | The mind must produce by its own power an image of the individual species [Aquinas] |
Full Idea: The agent mind must itself turn to images, and produce by its own power in the receptive mind a representation as to species of whatever the images represent as individual. | |
From: Thomas Aquinas (Summa Theologicae [1265], Ch.5 Q85.1) | |
A reaction: Unlike much of this section, this sentence supports Geach's claim that Aquinas agrees with him - that the mind creates its concepts, rather than 'abstracting' them from experience. |
2439 | Semantic externalism says the concept 'elm' needs no further beliefs or inferences [Fodor] |
Full Idea: It is the essence of semantic externalism that there is nothing that you have to believe, there are no inferences that you have to accept, to have the concept 'elm'. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §2.I) | |
A reaction: [REMINDER: broad content is filed in 18.C.7, under 'Thought' rather than under language. That is because I am a philospher of thought, rather than of language. |
2457 | If meaning is information, that establishes the causal link between the state of the world and our beliefs [Fodor] |
Full Idea: It is the causal connection between the state of the world and the contents of beliefs that the reduction of meaning to information is designed to insure. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §4) | |
A reaction: I'm not clear why characterising the contents of a belief in terms of its information has to amount to a 'reduction'. A cup of tea isn't reduced to tea. Connections imply duality. |
2998 | Grice thinks meaning is inherited from the propositional attitudes which sentences express [Fodor] |
Full Idea: According to Gricean theories of meaning, the meaning of a sentence is inherited from the propositional attitudes that the sentence is conventionally used to express. | |
From: Jerry A. Fodor (Psychosemantics [1987], p. 50) | |
A reaction: Since the propositional attitudes contain propositions, this seems like a very plausible idea. If an indexical like 'I' is involved, the meaning of the sentence is not the same as its 'conventional' use. |
2482 | It seems unlikely that meaning can be reduced to communicative intentions, or any mental states [Fodor] |
Full Idea: Nobody now thinks that the reduction of the meaning of English sentences to facts about the communicative intentions of English speakers - or to any facts about mental states - is likely to go through. | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 6) | |
A reaction: Most attempts at 'reduction' of meaning seem to go rather badly. I assume it would be very difficult to characterise 'intentions' without implicit reference to meaning. |
3006 | Whatever in the mind delivers falsehood is parasitic on what delivers truth [Fodor] |
Full Idea: The mechanisms that deliver falsehoods are somehow parasitic on the ones that deliver truths. | |
From: Jerry A. Fodor (Psychosemantics [1987], p.107) | |
A reaction: In the case of a sentence and its negation it is not clear which one is 'parasitic', because that can usually be reversed by paraphrasing. Historically, I very much hope that truth-speaking came first. |
2451 | To know the content of a thought is to know what would make it true [Fodor] |
Full Idea: If you know the content of a thought, you thereby know what would make the thought true. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §4) | |
A reaction: The truthmaker might by physically impossible, and careful thought might show it to be contradictory - but that wouldn't destroy the meaning. |
3007 | Many different verification procedures can reach 'star', but it only has one semantic value [Fodor] |
Full Idea: Verification procedures connect terms with their denotations in too many ways. Different routes to 'star' do not determine different semantic values for 'star'. | |
From: Jerry A. Fodor (Psychosemantics [1987], p.125) | |
A reaction: This fairly conclusively shows that meaning is not 'the method of verification' - but that wasn't a difficult target to hit. |
3004 | The meaning of a sentence derives from its use in expressing an attitude [Fodor] |
Full Idea: The meaning of a sentence derives from its use in expressing an attitude. | |
From: Jerry A. Fodor (Psychosemantics [1987], p. 79) | |
A reaction: Among other things. It can also arrive from a desire to remember something. A sentence can also acquire meaning compositionally (by assembling) with no use or aim. |
2433 | For holists no two thoughts are ever quite the same, which destroys faith in meaning [Fodor] |
Full Idea: If what you are thinking depends on all of what you believe, then nobody ever thinks the same thing twice. …That is why so many semantic holists (Quine, Putnam, Rorty, Churchland, probably Wittgenstein) end up being semantic eliminativists. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §1.2b) | |
A reaction: If linguistic holism is nonsense, this is easily settled. What I say about breakfast is not changed by reading some Gibbon yesterday. |
2477 | If to understand "fish" you must know facts about them, where does that end? [Fodor] |
Full Idea: If learning that fish typically live in streams is part of learning "fish", typical utterances of "pet fish" (living in bowls) are counterexamples. This argument iterates (e.g "big pet fish"). So learning where they live can't be part of learning "fish". | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 5) | |
A reaction: Using 'typical' twice is rather misleading here. Town folk can learn 'fish' as typically living in bowls. There is no one way to learn a word meaning. |
3000 | Meaning holism is a crazy doctrine [Fodor] |
Full Idea: Meaning holism really is a crazy doctrine. | |
From: Jerry A. Fodor (Psychosemantics [1987], p. 60) | |
A reaction: Yes. What is not crazy is a contextualist account of utterances, and a recognition of the contextual and relational ingredient in the meanings of most of our sentences. |
3003 | Very different mental states can share their contents, so content doesn't seem to be constructed from functional role [Fodor] |
Full Idea: It's an embarrassment for attempts to construct content from functional role that quite different sorts of mental states can nevertheless share their contents. | |
From: Jerry A. Fodor (Psychosemantics [1987], p. 70) | |
A reaction: That is, presumably, one content having two different roles. Two contents with the same role is 'multiple realisability'. Pain can tell me I'm damaged, or reveal that my damaged nerves are healing. Problem? |
12634 | 'Inferential-role semantics' says meaning is determined by role in inference [Fodor] |
Full Idea: 'Inferential-role semantics' claims that the meaning of a word (/the content of a concept) is determined by its role in inference. | |
From: Jerry A. Fodor (LOT 2 [2008], Ch.2.1.2 n14) | |
A reaction: Fodor is deeply opposed to this view. At first blush it sounds wrong to me, since there seems to be plenty of thought that can go on before inference takes place. Daydreamy speculation, for example. |
2996 | Mental states may have the same content but different extensions [Fodor] |
Full Idea: The identity of the content of mental states does not ensure the identity of their extensions. | |
From: Jerry A. Fodor (Psychosemantics [1987], p. 45) | |
A reaction: Obviously if I am thinking each day about 'my sheep', that won't change if I am unaware that one of them died this morning. …Because I didn’t have the precise number of sheep in mind. |
12642 | Co-referring terms differ if they have different causal powers [Fodor] |
Full Idea: The representation of 'morning star' must be different from 'evening star' because their tokens differ in their causal powers. | |
From: Jerry A. Fodor (LOT 2 [2008], Ch.3.3) | |
A reaction: This is Fodor trying to avoid the standard Fregean move of proposing that there are 'senses' as well as references. See Idea 12629. If these two terms have the same extension, they are the same concept? They 'seem' to have two referents. |
12663 | We refer to individuals and to properties, and we use singular terms and predicates [Fodor] |
Full Idea: I assume that there are two kinds of reference: reference to individuals and to properties. This means, from the syntactic point of view, that the vehicles of reference are exhaustively singular terms and predicates. | |
From: Jerry A. Fodor (LOT 2 [2008], Ch.7) | |
A reaction: The immediate possibility that comes to mind is plural quantification. See George Boolos, who confidently says that he can refer to 'some Cheerios' in his breakfast bowl, and communicate very well. He then looks to formalise such talk. |
2436 | It is claimed that reference doesn't fix sense (Jocasta), and sense doesn't fix reference (Twin Earth) [Fodor] |
Full Idea: The standard view is that Frege cases [knowing Jocasta but not mother] show that reference doesn't determine sense, and Twin cases [knowing water but not H2O] show that sense doesn't determine reference. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §1.3) | |
A reaction: How about 'references don't contain much information', and 'descriptions may not fix what they are referring to'? Simple really. |
12616 | English has no semantic theory, just associations between sentences and thoughts [Fodor] |
Full Idea: English has no semantics. Learning English isn't learning a theory about what its sentences mean, it's learning how to associate its sentences with the corresponding thoughts. | |
From: Jerry A. Fodor (Concepts:where cogn.science went wrong [1998], Ch.1) | |
A reaction: This sounds remarkably close to John Locke's account of language (which I always thought was seriously underrated). Presumably we can then say that the 'thought' (or Locke's 'idea') is the meaning, which is old-fashioned real meanings. |
12645 | Semantics (esp. referential semantics) allows inferences from utterances to the world [Fodor] |
Full Idea: All you need for inferring from John's utterance to the world is the sort of thing that a semantics (i.e. referential semantics) provides. | |
From: Jerry A. Fodor (LOT 2 [2008], Ch.3.5) | |
A reaction: Fodor is very good at saying nice simple things like that. But it is not enough to infer what objects are being discussed. All the hard cases must be covered (denials of existence, reference to non-existence, intentional contexts, modal claims). |
12646 | Semantics relates to the world, so it is never just psychological [Fodor] |
Full Idea: Semantics is about constitutive relations between representations and the world. There is, as a matter of principle, no such thing as a psychological theory of meaning. | |
From: Jerry A. Fodor (LOT 2 [2008], Ch.3.5) | |
A reaction: The second sentence is in capital letters, but I am still not convinced. The classic difficulty seems to be that you have to use language to pick out the things in the world that are being referred to. Of course, at some point you just see the objects. |
2434 | Broad semantics holds that the basic semantic properties are truth and denotation [Fodor] |
Full Idea: Broad semantic theories generally hold that the basic semantic properties of thoughts are truth and denotation. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §1.2b) | |
A reaction: I think truth and denotation are the basic semantic properties, but I am dubious about whole-hearted broad semantic theories, so I seem to have gone horribly wrong somewhere. |
11206 | The mind constructs complete attributions, based on the unified elements of the real world [Aquinas] |
Full Idea: Attribution is something mind brings to completion by constructing propositional connections and disconnections, basing itself on real-world unity possessed by the things being attributed to one another. | |
From: Thomas Aquinas (De Ente et Essentia (Being and Essence) [1267], p.102) | |
A reaction: This compromise story seems to me to be exactly right. I take it that we respond to the real joints of nature, but using thought and language which is riddled with convention. |
2459 | Externalist semantics are necessary to connect the contents of beliefs with how the world is [Fodor] |
Full Idea: You need an externalist semantics to explain why the contents of beliefs should have anything to do with how the world is. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §4) | |
A reaction: Since externalist semantics only emerged in the 1970s, that implies that no previous theory had any notion that language had some connection to how the world is. Eh? |
2473 | Analysis is impossible without the analytic/synthetic distinction [Fodor] |
Full Idea: If there is no analytic/synthetic distinction then there are no analyses. | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 3) | |
A reaction: There are no precise analyses. I see no reason why a holistic view of language prohibits the careful elucidation of key concepts in the system. It's just a bit fluid. |
2484 | The theory of the content of thought as 'Mentalese' explains why the Private Language Argument doesn't work [Fodor] |
Full Idea: If the Mentalese story about the content of thought is true, then there couldn't be a Private Language Argument. Good. That explains why there isn't one. | |
From: Jerry A. Fodor (In a Critical Condition [2000], Ch. 6) | |
A reaction: Presumably Mentalese implies that all language is, in the first instance, intrinsically private. Dogs, for example, need Mentalese, since they self-evidently think. |
1857 | We don't have to will even perfect good, because we can choose not to think of it [Aquinas] |
Full Idea: The will can avoid actually willing something by avoiding thinking of it, since mental activity is subject to will. In this respect we aren't compelled to will even total happiness, which is the only perfect good. | |
From: Thomas Aquinas (Quaestiones Disputatae de Malo [1271], Q6.h to 07) |
23180 | The will is the rational appetite [Aquinas] |
Full Idea: The will is the rational appetite. | |
From: Thomas Aquinas (Summa Theologicae [1265], II-II Q58 4) | |
A reaction: Defining the will in terms of reason sounds more like an Enlightenment optimist than a medieval theologian. I suspect that for him it is tautological the reason is involved, if only the reason can make decisions. Hobbes prefers to ruling appetite. |
1846 | The will can only want what it thinks is good [Aquinas] |
Full Idea: Will's object is what is good, and so it cannot will anything but what is good. | |
From: Thomas Aquinas (Quaestiones Disputatae de Malo [1271], Q6.06) |
1847 | The will must aim at happiness, but can choose the means [Aquinas] |
Full Idea: The will is compelled by its ultimate goal (to achieve happiness), but not by the means to achieve it. | |
From: Thomas Aquinas (Quaestiones Disputatae de Malo [1271], Q6.07) |
12627 | Before you can plan action, you must decide on the truth of your estimate of success [Fodor] |
Full Idea: You can't think a plan of action unless you can think how the world would be if the action were to succeed; and thinking the world will be such and such if all goes well is thinking the kind of thing that can be true or false. | |
From: Jerry A. Fodor (LOT 2 [2008], Ch.1) | |
A reaction: This is part of Fodor's attack on the pragmatic view of concepts (that they should be fully understood in terms of action, rather than of thought). I take Fodor to be blatantly correct. This is counterfactual thinking. |
1850 | Without free will not only is ethical action meaningless, but also planning, commanding, praising and blaming [Aquinas] |
Full Idea: If we are not free to will in any way, but are compelled, everything that makes up ethics vanishes: pondering action, exhorting, commanding, punishing, praising, condemning. | |
From: Thomas Aquinas (Quaestiones Disputatae de Malo [1271], Q6.reply) | |
A reaction: If doesn't require some magical 'free will' to avoid compulsions. All that is needed is freedom to enact your own willing, rather than someone else's. |
22112 | For humans good is accordance with reason, and bad is contrary to reason [Aquinas] |
Full Idea: A human being's good is existing in accordance with reason, while what is bad for a human being is whatever is contrary to reason. | |
From: Thomas Aquinas (Summa Theologicae [1265], Ia IIae.Q18.5c), quoted by Kretzmann/Stump - Aquinas, Thomas 13 | |
A reaction: For anyone who thought Kant invented the idea that morality derives from reason. This idea of Aquinas is a fairly precise echo of the stoic view (which influenced Kant). Is there a circularity? Is it irrational because bad, or bad because irrational? |
22494 | We must know the end, know that it is the end, and know how to attain it [Aquinas] |
Full Idea: Perfect knowledge of the end consists in not only apprehending the thing which is the end but also knowing it under the aspect of the end and the relation of the means to that end. | |
From: Thomas Aquinas (Summa Theologicae [1265], II-I.Q132), quoted by Philippa Foot - Natural Goodness 4 | |
A reaction: We don't talk much now about 'perfect' knowledge of something, but I suppose this is the necessary and sufficient conditions. If you complete the checklist, your knowledge should be perfect (if the list is right). |
1851 | Good applies to goals, just as truth applies to ideas in the mind [Aquinas] |
Full Idea: Good applies to all goals, just as truth applies to all forms mind takes in. | |
From: Thomas Aquinas (Quaestiones Disputatae de Malo [1271], Q6.reply) | |
A reaction: In danger of being tautological, if good is understood as no more than the goal of actions. It seems perfectly possibly to pursue a wicked end, and perhaps feel guilty about it. |
23181 | All acts of virtue relate to justice, which is directed towards the common good [Aquinas] |
Full Idea: The good of any virtue …is referable to the common good, to which justice directs, so that all acts of virtue can pertain to justice insofar as it directs man to the common good. | |
From: Thomas Aquinas (Summa Theologicae [1265], II-II Q58 5) | |
A reaction: Michael Sandel has recently lamented to fading of the concept of 'the common good' from our moral and political life. In which case this thought of Aquinas takes on great importance. I certainly like it. It seems to apply to courage, for example. |
8009 | Aquinas wanted, not to escape desire, but to transform it for moral ends [Aquinas, by MacIntyre] |
Full Idea: The Aristotelianism of Thomas Aquinas (unlike St Augustine's Platonism) is not concerned with escaping from the snares of the world and of desire, but with transforming desire for moral ends. | |
From: report of Thomas Aquinas (Summa Theologicae [1265]) by Alasdair MacIntyre - A Short History of Ethics Ch.9 | |
A reaction: This is very close to Aristotle himself, for whom education of the feelings (into good habits, and then true virtues) was central. Education of feelings should be central to all education (though young psychopaths may show resistance). |
23182 | Legal justice is supreme, because it directs the other virtues to the common good [Aquinas] |
Full Idea: There must be one supreme virtue essentially distinct from every other virtue, which directs all the virtues to the common good, and this virtue is legal justice. | |
From: Thomas Aquinas (Summa Theologicae [1265], II-II Q58 6) | |
A reaction: This concept of legal justice is underpinned, for Aquinas, by the concept of natural law, which has divine backing. Positive law could hardly fulfil such a major role, given that it could be corrupt. |
22399 | Temperance prevents our passions from acting against reason [Aquinas] |
Full Idea: The passions may incite us to something against reason, and so we need a curb, which we name 'temperance'. | |
From: Thomas Aquinas (Summa Theologicae [1265], Ia 2ae Q61 a.3), quoted by Philippa Foot - Virtues and Vices II | |
A reaction: I am increasingly unclear what 'reason' means in contexts like these. It seems to mean no more than the awareness of greater goods than the indulgence of passion. Without that awareness, high intelligence couldn't produce temperance. |
23177 | Justice directs our relations with others, because it denotes a kind of equality [Aquinas] |
Full Idea: It is proper to justice, as compared with the other virtues, to direct man in his relations with others, because it denotes a kind of equality, as its very name implies; indeed we are wont to say that things are 'adjusted' when they are made equal. | |
From: Thomas Aquinas (Summa Theologicae [1265], II-II Q57 1) | |
A reaction: Even if you say justice is giving people what they deserve, rather than mere equality, they must still be equal in receiving like for like. Legal justice implies equality before the law (except for monarchs?). |
23179 | People differ in their social degrees, and a particular type of right applies to each [Aquinas] |
Full Idea: There are many differences of degrees among men, for instance, some are soldiers, some are priests, some are princes. Therefore some special kind of right should be alloted to them. | |
From: Thomas Aquinas (Summa Theologicae [1265], II-II Q57 4) | |
A reaction: An objection (3), but Aquinas endorses it in his reply. In 58.10 he says striking a prince is worse that striking a commoner. The shift to the idea that everyone is supposed to be equal before the law has been slow, and we are not quite there yet. |
22114 | Tyrannical laws are irrational, and so not really laws [Aquinas] |
Full Idea: A tyrannical law, since it is not in accord with reason, is not unconditionally a law, but is rather a perversion of law. | |
From: Thomas Aquinas (Summa Theologicae [1265], Ia IIae.Q92.1, ad 4), quoted by Kretzmann/Stump - Aquinas, Thomas 13 | |
A reaction: Only a belief in natural law can give a basis for such a claim. Positivists will say a tyrannical law is unconditionally a law like any other, but a bad one. |
23174 | Natural law is a rational creature's participation in eternal law [Aquinas] |
Full Idea: It is evident that the natural law is nothing else than the rational creature's participation of the eternal law. | |
From: Thomas Aquinas (Summa Theologicae [1265], I-II Q91 2) | |
A reaction: It is not enough merely that God decrees eternal laws. It is also necessary for us to use reason in order to participate. I'm not sure what reasoning process is involved. |
22113 | Right and wrong actions pertain to natural law, as perceived by practical reason [Aquinas] |
Full Idea: All things to be done or to be avoided pertain to the precepts of natural law, which practical reasoning apprehends naturally as being human goods. | |
From: Thomas Aquinas (Summa Theologicae [1265], Ia IIae.Q94.2c), quoted by Kretzmann/Stump - Aquinas, Thomas 13 | |
A reaction: No mention of God, but you feel the divine presence in the background. He also cites 'eternal law'. No coincidence that the atheist Hobbes rejected natural law. Personally I would offer an atheistic defence of natural law, based on human nature. |
7291 | For Aquinas a war must be in a just cause, have proper authority, and aim at good [Aquinas, by Grayling] |
Full Idea: Aquinas argued that on three conditions war can be justified: first, that there is a just cause; second, that it is begun on proper authority; and third, that it is waged with right intention, for 'the advancement of good, or the avoidance of evil'. | |
From: report of Thomas Aquinas (Summa Theologicae [1265], II) by A.C. Grayling - Among the Dead Cities Ch.6 | |
A reaction: But see also Idea 7292. Nowadays we are rightly suspicious of all three conditions. Evil people seem to think their cause is just; authority has often been seized by violence, or is being abused; and people seem confused about what is good or evil. |
5508 | Aquinas says a fertilized egg is not human, and has no immortal soul [Aquinas, by Martin/Barresi] |
Full Idea: In Aquinas's view the fertilized egg is not, either at the moment of conception or for quite a while afterwards, endowed with an immortal soul. In fact, technically speaking, it is not even human. | |
From: report of Thomas Aquinas (Summa Theologicae [1265]) by R Martin / J Barresi - Introduction to 'Personal Identity' p.20 | |
A reaction: It is pointed at that therefore Aquinas does not give good support for modern Catholic views on abortion. There is certainly no reason why a human zygote should be ensouled from the start, as God may do this whenever He wishes. |
16687 | Bodies are three-dimensional substances [Aquinas] |
Full Idea: Bodies are those substances in which one finds three dimensions. | |
From: Thomas Aquinas (Summa Theologicae [1265], Ia Q18.2c), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 16.2 | |
A reaction: Pasnau points out that this extensional view of physical bodies was a commonplace long before Descartes. Presumably there are also non-dimensional substances (such as angels?). |
11207 | A cause can exist without its effect, but the effect cannot exist without its cause [Aquinas] |
Full Idea: When things are so related that one causes the other to exist, the cause can exist without what it causes but not vice versa. | |
From: Thomas Aquinas (De Ente et Essentia (Being and Essence) [1267], p.103) | |
A reaction: This is open to question, if causes are supposed to be sufficient for effects. Presumably Aquinas would support the view that if the cause had not been, the effect would not have happened. But the current idea indicates the priority relation. |
1859 | Even a sufficient cause doesn't compel its effect, because interference could interrupt the process [Aquinas] |
Full Idea: Even a sufficient cause doesn't always compel its effect, since it can sometimes be interfered with so that its effect doesn't happen | |
From: Thomas Aquinas (Quaestiones Disputatae de Malo [1271], Q6.h to 15) |
3977 | Laws are true generalisations which support counterfactuals and are confirmed by instances [Fodor] |
Full Idea: Laws are true generalisations that support counterfactuals and are confirmed by their instances. | |
From: Jerry A. Fodor (Jerry A. Fodor on himself [1994], p.293) | |
A reaction: This seems correct, but it doesn't disentangle laws as mental states from laws as features of nature |
15202 | Eternity coexists with passing time, as the centre of a circle coexists with its circumference [Aquinas] |
Full Idea: The centre of a circle is directly opposite any designated point on the circumference. In this way, whatever is in any part of time coexists with what is eternal as being present to it even though past or future with respect to another part of time. | |
From: Thomas Aquinas (Summa Contra Gentiles [1268], I.66), quoted by Robin Le Poidevin - Past, Present and Future of Debate about Tense 2 c | |
A reaction: A nice example of a really cool analogy which almost gets you to accept something which is actually completely incomprehensible. |
23178 | Divine law commands some things because they are good, while others are good because commanded [Aquinas] |
Full Idea: The divine law commands certain things because they are good and forbids others because they are evil, while others are good because they are prescribed, and others evil because they are forbidden. | |
From: Thomas Aquinas (Summa Theologicae [1265], II-II Q57 2) | |
A reaction: This is a fifty-fifty response to the Euthyphro dilemma, but it seems to leave the theological puzzle of the source of the goodness which is prescribed because it is in fact good. |
21251 | We can't know God's essence, so his existence can't be self-evident for us [Aquinas] |
Full Idea: Because we do not know the essence of God, the proposition 'God exists' is not self-evident to us, but needs to be demonstrated by things that are more known to us. | |
From: Thomas Aquinas (Summa Theologicae [1265], Art 1, Obj 3) | |
A reaction: Depends on his definition of self-evidence (Idea 21250), which needs knowledge of the essence of the subject. Anselm required 'understanding' of the concept. One might understand the existence criteria without knowing the whole essence. Anselm wins. |
5614 | If you assume that there must be a necessary being, you can't say which being has this quality [Kant on Aquinas] |
Full Idea: To those who assume the existence of a necessary being, and would only know which among all things had to be regarded as such a thing, one could not answer: This thing here is the necessary being | |
From: comment on Thomas Aquinas (Summa Theologicae [1265]) by Immanuel Kant - Critique of Pure Reason A612/B640 | |
A reaction: See Aquinas in Idea 1431. Kant makes a nice point. You might turn out to be the necessary being? How could you tell? You only know that there must be one lurking somewhere. I could be a slug. Aquinas makes a huge leap to God. |
21269 | Way 1: the infinite chain of potential-to-actual movement has to have a first mover [Aquinas] |
Full Idea: A thing can only be reduced from potentiality to actuality by something actual. A thing can never be in actuality and potentiality in the same respect. So what is moved must be moved by another. But this cannot go on to infinity, with no first mover. | |
From: Thomas Aquinas (Summa Theologicae [1265], Ia,Q02,Art3,Reply) | |
A reaction: [compressed] This relies on the Aristotelian ideas of potentiality and actuality. We might talk about things moving, but lacking the 'power' to move. This is almost identical to Plato in 'The Laws' (which I guess Aquinas knew nothing of). |
21271 | Way 3: contingent beings eventually vanish, so continuity needs a necessary being [Aquinas] |
Full Idea: That which can not-be at some time is not. So if everything can not-be, then once there was nothing in existence. If so, it would have been impossible for anything to have begun to exist. So there must be some being having of itself its own necessity. | |
From: Thomas Aquinas (Summa Theologicae [1265], Ia,Q02,Art3,Reply) | |
A reaction: [compressed] Why can't things take it in turns to not-be, so that something is always on duty? Maybe it is a feature of things that they bring other things into existence (e.g. virtual particles)? |
21270 | Way 2: no effect without a cause, and this cannot go back to infinity, so there is First Cause [Aquinas] |
Full Idea: If there is no first cause among efficient causes, there is no ultimate or intermediate cause. That in efficient causes it is possible to go on to infinity is plainly false. So it is necessary to admit a first efficient cause, which everyone calls God. | |
From: Thomas Aquinas (Summa Theologicae [1265], Ia,Q02,Art3,Reply) | |
A reaction: [compressed] It doesn't seem to follow at all that the First Cause is God. There could be a single thing like the Phoenix, with unique self-causing properties. Or a quantum fluctuation. |
21272 | Way 4: the source of all qualities is their maximum, so something (God) causes all perfections [Aquinas] |
Full Idea: More and less are predicated of different things according as they resemble in their different ways something which is the maximum. The maximum of a genus is the cause of all in that genus. So there must be something causing the perfections of all beings. | |
From: Thomas Aquinas (Summa Theologicae [1265], Ia,Q02,Art3,Reply) | |
A reaction: [compressed] The argument makes a startling jump from each quality (like heat or nobility) having a maximum, to their being a single entity (a 'being' at that) which is the sole source of all human perfections. |
21273 | Way 5: mindless things act towards an obvious end, so there is an intelligent director [Aquinas] |
Full Idea: Things which lack knowledge, such as natural bodies, act for an end, which is usually in the same way, to obtain the best result. Hence they achieve their end designedly. Hence some intelligent being exists by whom all natural things are directed. | |
From: Thomas Aquinas (Summa Theologicae [1265], Ia,Q02,Art3,Reply) | |
A reaction: [compressed] This is Greek teleology with a vengeance. Plants probably illustrate best what he has in mind. There is obvious teleology in human affairs, and there is a sort of teleology in living things, but we take the end to be reinforced by success. |
20211 | Life aims at the Beatific Vision - of perfect happiness, and revealed truth [Aquinas, by Zagzebski] |
Full Idea: Aquinas describes the ultimate end of human life as the Beatific Vision, a state that is simultaneously the enjoyment of perfect happiness and a perfect revelation of truth. | |
From: report of Thomas Aquinas (Summa Theologicae [1265]) by Linda Trinkaus Zagzebski - Virtues of the Mind II 4.2 | |
A reaction: I like that a lot, even though my idea of the revelation of truth is very distant from that of Aquinas. Ignorant happiness is not much of an aspiration. |
22106 | Aquinas saw angels as separated forms, rather than as made of 'spiritual matter' [Aquinas, by Kretzmann/Stump] |
Full Idea: Unlike some of his contemporaries, Aquinas does not think that there is a 'spiritual matter' that angels or disembodied souls have as one of their components, but rather that they are separated forms that configure no matter at all. | |
From: report of Thomas Aquinas (Summa Theologicae [1265]) by Kretzmann/Stump - Aquinas, Thomas 10 | |
A reaction: 'Separated forms' sounds like the modern concept of abstract entities, meaning that souls and angels exist in the way that platonists believe numbers exist. How else might Aquinas have understood them? |
16711 | Heretics should be eradicated like wolves [Aquinas] |
Full Idea: Heretics are wolves …and therefore ought to be eradicated. | |
From: Thomas Aquinas (Sentences [1264], IV.13.2.3sc), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 20.2 |
23306 | Humans have a non-physical faculty of reason, so they can be immortal [Aquinas, by Sorabji] |
Full Idea: Aquinas infers from Aristotle that intellectual understanding is the only operation of the soul that is performed without a physical organ, so that only human souls, and not animal ones, can be immortal. | |
From: report of Thomas Aquinas (Summa Theologicae [1265], I, q75, a3, resp) by Richard Sorabji - Rationality 'Reason' | |
A reaction: This shows why so many thinkers are desperate to hang on to dualism, of some sort. Interesting that he only claims partial dualism. |
1863 | If the soul achieves well-being in another life, it doesn't follow that I do [Aquinas] |
Full Idea: Even if soul achieves well-being in another life, that doesn't mean I do or any other human being does. | |
From: Thomas Aquinas (Super Epistolam Pauli Apostoli [1272]) |
4412 | Those in bliss have their happiness increased by seeing the damned punished [Aquinas] |
Full Idea: In order that the bliss of the saints may be more delightful for them, and they may render more copious thanks to God for it, it is given to them to see perfectly the punishment of the damned. | |
From: Thomas Aquinas (Summa Theologicae [1265], III Supp Q94,1), quoted by Friedrich Nietzsche - On the Genealogy of Morals I.§15 | |
A reaction: This has probably been repudiated by the Church of England. Justice should be seen to be done. Presumably you mustn't gloat, or you join them. |
21266 | God does not exist, because He is infinite and good, and so no evil should be discoverable [Aquinas] |
Full Idea: If one of two contraries be infinite, the other would be altogether destroyed. But the name God means that He is infinite goodness. If therefore God existed there would be no evil discoverable; but there is evil in the world. Therefore God does not exist. | |
From: Thomas Aquinas (Summa Theologicae [1265], Ia,Q02,Art3,Ob1) | |
A reaction: This is not, of course, the opinion of Aquinas. I love the way he states the opposition's arguments so lucidly. The modern problem usually talks of God's omnipotence, rather than infinity. His formulation allows that there might be undiscoverable evil. |
21274 | It is part of God's supreme goodness that He brings good even out of evil [Aquinas] |
Full Idea: As Augustine says, God would not allow any evil to exist in his works, unless he were to bring good even out of evil. It is part of the infinite goodness of God, that He allows evil to exist and out of it produces good. | |
From: Thomas Aquinas (Summa Theologicae [1265], Ia,Q02,Art3,Ob1rep) | |
A reaction: Are God's powers so limited that He could not have achieved an equal amount of good without having to indulge in some evil first? |
