145 ideas
| 22659 | It is wisdom to believe what you desire, because belief is needed to achieve it [James] |
| Full Idea: Clearly it is often the part of wisdom to believe what one desires; for the belief is one of indispensable preliminary conditions of the realisation of its object. | |
| From: William James (The Sentiment of Rationality [1882], p.43) | |
| A reaction: Roughly, action is impossible without optimism about possible success. This may count as instinct, rather than 'wisdom'. |
| 22657 | All good philosophers start from a dumb conviction about which truths can be revealed [James] |
| Full Idea: Every philosopher whose initiative counts for anything in the evolution of thought has taken his stand on a sort of dumb conviction that the truth must lie in one direction rather than another, and a preliminary assurance that this can be made to work. | |
| From: William James (The Sentiment of Rationality [1882], p.40) | |
| A reaction: I would refer to this as 'intuition', which I think of as reasons (probably good reasons) which cannot yet be articulated. Hence I like this idea very much, except for the word 'dumb'. It is more like a rational vision, yet to be filled in. |
| 22647 | A complete system is just a classification of the whole world's ingredients [James] |
| Full Idea: A completed theoretic philosophy can never be anything more than a completed classification of the world's ingredients. | |
| From: William James (The Sentiment of Rationality [1882], p.23) | |
| A reaction: I assume this is not just the physical ingredients, but must also include our conceptual scheme - but then we must first decide which is the best conceptual scheme to classify, and that's where the real action is. [He scorns such classifation later]. |
| 14092 | Philosophers are often too fussy about words, dismissing perfectly useful ordinary terms [Rosen] |
| Full Idea: Philosophers can sometimes be too fussy about the words they use, dismissing as 'unintelligible' or 'obscure' certain forms of language that are perfectly meaningful by ordinary standards, and which may be of some real use. | |
| From: Gideon Rosen (Metaphysical Dependence [2010], 01) | |
| A reaction: Analytic philosophers are inclined to drop terms they can't formalise, but there is more to every concept than its formalisation (Frege's 'direction' for example). I want to rescue 'abstraction' and 'essence'. Rosen says distinguish, don't formalise. |
| 22648 | A single explanation must have a single point of view [James] |
| Full Idea: A single explanation of a fact only explains it from a single point of view. | |
| From: William James (The Sentiment of Rationality [1882], p.23) | |
| A reaction: I take this to imply that multiple viewpoints lead us towards objectivity. The single viewpoint of an expert is of much greater value than that of a novice, on the whole. |
| 22642 | Man has an intense natural interest in the consistency of his own thinking [James] |
| Full Idea: After man's interest in breathing freely, the greatest of all his interests (because it never fluctuates or remits….) is his interest in consistency, in feeling that what he now thinks goes with what he thinks on other occasions. | |
| From: William James (The Pragmatist Account of Truth [1908], 'Seventh') | |
| A reaction: People notoriously contradict themselves all the time, but I suspect that it is when they get out of their depth in complexities such as politics. They probably achieve great consistency within their own expertise, and in common knowledge. |
| 22644 | Our greatest pleasure is the economy of reducing chaotic facts to one single fact [James] |
| Full Idea: Our pleasure at finding that a chaos of facts is the expression of single underlying fact is like a musician's relief at discovering harmony. …The passion for economy of means in thought is the philosophic passion par excellence. | |
| From: William James (The Sentiment of Rationality [1882], p.21) | |
| A reaction: We do, though, possess an inner klaxon warning against stupid simplistic reductions. Reducing all the miseries of life to the workings of the Devil is not satisfactory, even it it is economical. Simplicities are dangerously tempting. |
| 14100 | Figuring in the definition of a thing doesn't make it a part of that thing [Rosen] |
| Full Idea: From the simple fact that '1' figures in the definition of '2', it does not follow that 1 is part of 2. | |
| From: Gideon Rosen (Metaphysical Dependence [2010], 10) | |
| A reaction: He observes that quite independent things can be mentioned on the two sides of a definition, with no parthood relation. You begin to wonder what a definition really is. A causal chain? |
| 6710 | You can only define a statement that something is 'true' by referring to its functional possibilities [James] |
| Full Idea: Pragmatism insists that statements and beliefs are inertly and statically true only by courtesy: they practically pass for true; but you cannot define what you mean by calling them true without referring to their functional possibilities. | |
| From: William James (The Meaning of the Word "Truth" [1907], p.2) | |
| A reaction: I think this clarifies an objection to pragmatism, because all functional definitions (e.g. of the mind, or of moral behaviour) are preceded by the question of WHY this thing is able to function in this way. What special quality makes this possible? |
| 18986 | Truth is just a name for verification-processes [James] |
| Full Idea: Truth for us is simply a collective name for verification-processes, just as 'health' is a name for other processes in life. | |
| From: William James (Pragmatism - eight lectures [1907], Lec 6) | |
| A reaction: So the slogan is 'truth is success in belief'? Suicide and racist genocide can be 'successful'. I would have thought that truth was the end of a process, rather than the process itself. |
| 18983 | In many cases there is no obvious way in which ideas can agree with their object [James] |
| Full Idea: When you speak of the 'time-keeping function' of a clock, it is hard to see exactly what your ideas can copy. ...Where our ideas cannot copy definitely their object, what does agreement with that object mean? | |
| From: William James (Pragmatism - eight lectures [1907], Lec 6) | |
| A reaction: This is a very good criticism of the correspondence theory of truth. It looks a lovely theory when you can map components of a sentence (like 'the pen is in the drawer') onto components of reality - but it has to cover the hard cases. |
| 18972 | Ideas are true in so far as they co-ordinate our experiences [James] |
| Full Idea: Pragmatists say that ideas (which themselves are but parts of our experience) become true just in so far as they help us to get into satisfactory relation with other parts of our experience. | |
| From: William James (Pragmatism - eight lectures [1907], Lec 2) | |
| A reaction: I'm struck by the close similarity (at least in James) of the pragmatic view of truth and the coherence theory of truth (associated later with Blanshard). Perhaps the coherence theory is one version of the pragmatic account |
| 18973 | New opinions count as 'true' if they are assimilated to an individual's current beliefs [James] |
| Full Idea: A new opinion counts as 'true' just in proportion as it gratifies the individual's desire to assimilate the novel in his experience to his beliefs in stock. | |
| From: William James (Pragmatism - eight lectures [1907], Lec 2) | |
| A reaction: Note the tell-tale locution 'counts as' true, rather than 'is' true. The obvious problem is that someone with a big stock of foolish beliefs will 'count as' true some bad interpretation which is gratifyingly assimilated to their current confusions. |
| 18984 | True ideas are those we can assimilate, validate, corroborate and verify (and false otherwise) [James] |
| Full Idea: True ideas are those that we can assimilate, validate, corroborate and verify. False ideas are those that we cannot. | |
| From: William James (Pragmatism - eight lectures [1907], Lec 6) | |
| A reaction: The immediate question is why you should label something as 'false' simply on the grounds that you can't corroborate it. Proving the falsity is a stronger position than the ignorance James seems happy with. 'Assimilate' implies coherence. |
| 22305 | If the hypothesis of God is widely successful, it is true [James] |
| Full Idea: On pragmatistic principles, if the hypothesis of God works satisfactorily in the widest sense of the word, it is true. | |
| From: William James (The Meaning of the Word "Truth" [1907], p.299), quoted by Michael Potter - The Rise of Analytic Philosophy 1879-1930 35 'Prag' | |
| A reaction: How you get from 'widely satisfactory' to 'true' is beyond my comprehension. This is dangerous nonsense. This view of truth seems to be a commonplace in American culture. Peirce hurray! James boo! James accepted verification, where possible. |
| 18851 | Pairing (with Extensionality) guarantees an infinity of sets, just from a single element [Rosen] |
| Full Idea: In conjunction with Extensionality, Pairing entails that given a single non-set, infinitely many sets exist. | |
| From: Gideon Rosen (The Limits of Contingency [2006], 04) |
| 3137 | Varieties of singular terms are used to designate token particulars [Rey] |
| Full Idea: We designate token particulars with singular terms, such as: proper names, numerals, definite descriptions, demonstratives, pronouns or variables. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 1.1.1) |
| 14096 | Explanations fail to be monotonic [Rosen] |
| Full Idea: The failure of monotonicity is a general feature of explanatory relations. | |
| From: Gideon Rosen (Metaphysical Dependence [2010], 05) | |
| A reaction: In other words, explanations can always shift in the light of new evidence. In principle this is right, but some explanations just seem permanent, like plate-tectonics as explanation for earthquakes. |
| 3143 | Physics requires the existence of properties, and also the abstract objects of arithmetic [Rey] |
| Full Idea: Physics is committed to arithmetic, which seems committed to abstract objects such as numbers, and its causal explanations seem to appeal to properties, such as mass and charge. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 2.3) |
| 14097 | Things could be true 'in virtue of' others as relations between truths, or between truths and items [Rosen] |
| Full Idea: Our relation of 'in virtue of' is among facts or truths, whereas Fine's relation (if it is a relation at all) is a relation between a given truth and items whose natures ground that truth. | |
| From: Gideon Rosen (Metaphysical Dependence [2010], 07 n10) | |
| A reaction: This disagreement between two key players in the current debate on grounding looks rather significant. I think I favour Fine's view, as it seems more naturalistic, and less likely to succumb to conventionalism. |
| 14095 | Facts are structures of worldly items, rather like sentences, individuated by their ingredients [Rosen] |
| Full Idea: Facts are structured entities built up from worldly items rather as sentences are built up from words. They might be identified with Russellian propositions. They are individuated by their constituents and composition, and are fine-grained. | |
| From: Gideon Rosen (Metaphysical Dependence [2010], 04) | |
| A reaction: I'm a little cautious about the emphasis on being sentence-like. We have Russell's continual warnings against imposing subject-predicate structure on things. I think we should happily talk about 'facts' in metaphysics. |
| 22641 | Realities just are, and beliefs are true of them [James] |
| Full Idea: Realities are not true, they are; and beliefs are true of them. | |
| From: William James (The Pragmatist Account of Truth [1908], 'Fourth') | |
| A reaction: At last, a remark by James about truth which I really like. For 'realities' I would use the word 'facts'. |
| 22649 | Classification can only ever be for a particular purpose [James] |
| Full Idea: Every way of classifying a thing is but a way of handling it for some particular purpose. Conceptions, 'kinds', are teleological instruments. | |
| From: William James (The Sentiment of Rationality [1882], p.24) | |
| A reaction: Could there not be ways of classifying which suit all of our purposes? If there were a naturally correct way to classifying things, then any pragmatist would probably welcome that. (I don't say there is such a way). |
| 14093 | An 'intrinsic' property is one that depends on a thing and its parts, and not on its relations [Rosen] |
| Full Idea: One intuitive gloss on 'intrinsic' property is that a property is intrinsic iff whether or not a thing has it depends entirely on how things stand with it and its parts, and not on its relation to some distinct thing. | |
| From: Gideon Rosen (Metaphysical Dependence [2010], 02) | |
| A reaction: He offers this as a useful reward for reviving 'depends on' in metaphysical talk. The problem here would be to explain the 'thing' and its 'parts' without mentioning the target property. The thing certainly can't be a bundle of tropes. |
| 8915 | How we refer to abstractions is much less clear than how we refer to other things [Rosen] |
| Full Idea: It is unclear how we manage to refer determinately to abstract entities in a sense in which it is not unclear how we manage to refer determinately to other things. | |
| From: Gideon Rosen (Abstract Objects [2001], 'Way of Ex') | |
| A reaction: This is where problems of abstraction overlap with problems about reference in language. Can we have a 'baptism' account of each abstraction (even very large numbers)? Will descriptions do it? Do abstractions collapse into particulars when we refer? |
| 18852 | A Meinongian principle might say that there is an object for any modest class of properties [Rosen] |
| Full Idea: Meinongian abstraction principles say that for any (suitably restricted) class of properties, there exists an abstract entity (arbitrary object, subsistent entity) that possesses just those properties. | |
| From: Gideon Rosen (The Limits of Contingency [2006], 04) | |
| A reaction: This is 'Meinongian' because there will be an object which is circular and square. The nub of the idea presumably resides in what is meant by 'restricted'. An object possessing every conceivable property is, I guess, a step too far. |
| 18987 | A 'thing' is simply carved out of reality for human purposes [James] |
| Full Idea: What shall we call a 'thing' anyhow? It seems quite arbitrary, for we carve out everything, just as we carve out constellations, to suit our human purposes. | |
| From: William James (Pragmatism - eight lectures [1907], Lec 7) | |
| A reaction: James wrote just before the discovery of galaxies, which are much more obviously 'things' than constellations like the Plough are! This idea suggests a connection between pragmatism and the nihilist view of objects of Van Inwagen and co. |
| 18981 | 'Substance' is just a word for groupings and structures in experience [James] |
| Full Idea: 'Substance' appears now only as another name for the fact that phenomena as they come are actually grouped and given in coherent forms. | |
| From: William James (Pragmatism - eight lectures [1907], Lec 4) | |
| A reaction: This is the strongly empirical strain in James's empiricism. This sounds like a David Lewis comment on the Humean mosaic of experience. We Aristotelians at least believe that the groups run much deeper than the surface of experience. |
| 3145 | The Indiscernibility of Identicals is a truism; but the Identity of Indiscernibles depends on possible identical worlds [Rey] |
| Full Idea: Leibniz's Law, the indiscernibility of identicals, is a truism which should not be confused with the more controversial identity of indiscernibles, which depends on the possibility of perfectly replicated universes. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 2.4) |
| 18849 | Metaphysical necessity is absolute and universal; metaphysical possibility is very tolerant [Rosen] |
| Full Idea: If P is metaphysically necessary, then it is absolutely necessary, and necessary in every real (non-epistemic) sense; and if P is possible in any sense, then it's possible in the metaphysical sense. | |
| From: Gideon Rosen (The Limits of Contingency [2006], 02) | |
| A reaction: Rosen's shot at defining metaphysical necessity and possibility, and it looks pretty good to me. In my terms (drawing from Kit Fine) it is what is necessitated or permitted 'by everything'. So if it is necessitated by logic or nature, that's included. |
| 18850 | 'Metaphysical' modality is the one that makes the necessity or contingency of laws of nature interesting [Rosen] |
| Full Idea: 'Metaphysical' modality is the sort of modality relative to which it is an interesting question whether the laws of nature are necessary or contingent. | |
| From: Gideon Rosen (The Limits of Contingency [2006], 02) | |
| A reaction: Being an essentialist here, I take it that the stuff of the universe necessitates the so-called 'laws'. The metaphysically interesting question is whether the stuff might have been different. Search me! A nice test of metaphysical modality though. |
| 18858 | Sets, universals and aggregates may be metaphysically necessary in one sense, but not another [Rosen] |
| Full Idea: It may be metaphysically necessary in one sense that sets or universals or mereological aggregates exist, while in another sense existence is always a contingent matter. | |
| From: Gideon Rosen (The Limits of Contingency [2006], 10) | |
| A reaction: This idea depends on Idea 18856 and 18857. Personally I only think mereological aggregates and sets exist when people decide that they exist, so I don't see how they could ever be necessary. I'm unconvinced about his two concepts. |
| 14094 | The excellent notion of metaphysical 'necessity' cannot be defined [Rosen] |
| Full Idea: Many of our best words in philosophy do not admit of definition, the notion of metaphysical 'necessity' being one pertinent example. | |
| From: Gideon Rosen (Metaphysical Dependence [2010], 03) | |
| A reaction: Rosen is busy defending words in metaphysics which cannot be pinned down with logical rigour. We are allowed to write □ for 'necessary', and it is accepted by logicians as being stable in a language. |
| 18857 | Standard Metaphysical Necessity: P holds wherever the actual form of the world holds [Rosen] |
| Full Idea: According to the Standard Conception of Metaphysical Necessity, P is metaphysically necessary when it holds in every possible world in which the laws of metaphysics (about the form or structure of the actual world) hold | |
| From: Gideon Rosen (The Limits of Contingency [2006], 10) | |
| A reaction: Rosen has a second meaning, in Idea 18856. He thinks it is crucial to see that there are two senses, because many things come out as metaphysically necessary on one concept, but contingent on the other. Interesting.... |
| 18856 | Non-Standard Metaphysical Necessity: when ¬P is incompatible with the nature of things [Rosen] |
| Full Idea: According to the Non-Standard conception of Metaphysical Necessity, P is metaphysically necessary when its negation is logically incompatible with the nature of things. | |
| From: Gideon Rosen (The Limits of Contingency [2006], 10) | |
| A reaction: Rosen's new second meaning of the term. My immediate problem is with it resting on being 'logically' incompatible. Are squares 'logically' incompatible with circles? I like the idea that it rests on 'the nature of things'. (Psst! natures = essences) |
| 18848 | Something may be necessary because of logic, but is that therefore a special sort of necessity? [Rosen] |
| Full Idea: It is one thing to say that P is necessary in some generic sense because it is a truth of logic (true in all models of a language, perhaps). It is something else to say that P therefore enjoys a special sort of necessity. | |
| From: Gideon Rosen (The Limits of Contingency [2006], 02) | |
| A reaction: This encourages my thought that there is only one sort of necessity (what must be), and the variety comes from the different types of necessity makers (everything there could be, nature, duties, promises, logics, concepts...). |
| 18855 | Combinatorial theories of possibility assume the principles of combination don't change across worlds [Rosen] |
| Full Idea: Combinatorial theories of possibility take it for granted ....that possible worlds in general share a syntax, as it were, differing only in the constituents from which they are generated, or in the particular manner of their arrangements. | |
| From: Gideon Rosen (The Limits of Contingency [2006], 08) | |
| A reaction: For instance, it might assume that every world has 'objects', to which 'properties' and 'relations' can be attached, or to which 'functions' can apply. |
| 14101 | Are necessary truths rooted in essences, or also in basic grounding laws? [Rosen] |
| Full Idea: Fine says a truth is necessary when it is a logical consequence of the essential truths, but maybe it is a consequence of the essential truths together with the basic grounding laws (the 'Moorean connections'). | |
| From: Gideon Rosen (Metaphysical Dependence [2010], 13) | |
| A reaction: I'm with Fine all the way here, as we really don't need to clog nature up with things called 'grounding laws', which are both obscure and inexplicable. Fine's story is the one for naturalistically inclined philosophers. |
| 18853 | A proposition is 'correctly' conceivable if an ominiscient being could conceive it [Rosen] |
| Full Idea: To a first approximation, P is correctly conceivable iff it would be conceivable for a logically ominiscient being who was fully informed about the nature of things. | |
| From: Gideon Rosen (The Limits of Contingency [2006], 05) | |
| A reaction: Isn't the last bit covered by 'ominiscient'? Ah, I think the 'logically' only means they have a perfect grasp of what is consistent. This is to meet the standard problem, of ill-informed people 'conceiving' of things which are actually impossible. |
| 18974 | Truth is a species of good, being whatever proves itself good in the way of belief [James] |
| Full Idea: Truth is one species of good, and not, as is usually supposed, a category distinct from good, and co-ordinate with it. The true is whatever proves itself to be good in the way of belief, and good, too, for definite, assignable reasons. | |
| From: William James (Pragmatism - eight lectures [1907], Lec 2) | |
| A reaction: The trouble is that false optimism can often often be what is 'good in the way of belief'. That said, I think quite a good way to specify 'truth' is 'success in belief', but I mean intrinsically successful, not pragmatically successful. |
| 20298 | The traditional a priori is justified without experience; post-Quine it became unrevisable by experience [Rey] |
| Full Idea: Where Kant and others had traditionally assumed that the a priori concerned beliefs 'justifiable independently of experience', Quine and others of the time came to regard it as beliefs 'unrevisable in the light of experience'. | |
| From: Georges Rey (The Analytic/Synthetic Distinction [2013], 3.7) | |
| A reaction: That throws a rather striking light on Quine's project. Of course, if the a priori is also necessary, then it has to be unrevisable. But is a bachelor necessarily an unmarried man? It is not necessary that 'bachelor' has a fixed meaning. |
| 3172 | Empiricism says experience is both origin and justification of all knowledge [Rey] |
| Full Idea: Two of the key claims of empiricism are that all knowledge must be justified on the basis of experience, and that all knowledge in fact originates in experience. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 4.3) |
| 18989 | Pragmatism accepts any hypothesis which has useful consequences [James] |
| Full Idea: On pragmatic principles we cannot reject any hypothesis if consequences useful to life flow from it. | |
| From: William James (Pragmatism - eight lectures [1907], Lec 8) | |
| A reaction: Most governments seem to find lies more useful than the truth. Maybe most children are better off not knowing the truth about their parents. It might be disastrous to know the truth about what other people are thinking. Is 'useful but false' meaningful? |
| 22640 | We find satisfaction in consistency of all of our beliefs, perceptions and mental connections [James] |
| Full Idea: We find satisfaction in consistency between the present idea and the entire rest of our mental equipment, including the whole order of our sensations, and that of our intuitions of likeness and difference, and our whole stock previously acquired truths. | |
| From: William James (The Pragmatist Account of Truth [1908], 'Fourth') | |
| A reaction: I like this, apart from the idea that the criterion of good coherence seems to be subjective 'satisfaction'. We should ask why some large set of beliefs is coherent. I assume nature is coherent, and truth is the best explanation of our coherence about it. |
| 3166 | Animal learning is separate from their behaviour [Rey] |
| Full Idea: Rats and monkeys exhibit 'latent learning' (learning just for fun) which is later beneficial. They learn with no consequences, and then can't learn when the good consequences are available. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 4.1.1) | |
| A reaction: This looks like a bit of a setback for naturalised epistemology and cognitive science, if learning can't be brought within a stimulus-response framework. |
| 22655 | Scientific genius extracts more than other people from the same evidence [James] |
| Full Idea: What is the use of being a genius, unless with the same scientific evidence as other men, one can reach more truth than they? | |
| From: William James (The Sentiment of Rationality [1882], p.40) | |
| A reaction: This is aimed at Clifford's famous principle. He isn't actually contraverting the principle, but it is a nice point about evidence. Simple empiricists think detectives only have to stare at the evidence and the solution creates itself. |
| 22658 | Experimenters assume the theory is true, and stick to it as long as result don't disappoint [James] |
| Full Idea: Each tester of the truth of a theory …acts as if it were true, and expects the result to disappoint him if his assumption is false. The longer disappointment is delayed, the stronger grows his faith in his theory. | |
| From: William James (The Sentiment of Rationality [1882], p.42) | |
| A reaction: This is almost exactly Popper's falsificationist proposal for science, which interestingly shows the close relationship of his view to pragmatism. Believe it as long as it is still working. |
| 18971 | Theories are practical tools for progress, not answers to enigmas [James] |
| Full Idea: Theories are instruments, not answers to enigmas, in which we can rest. We don't lie back upon them, we move forward, and, on occasion, make nature over again by their aid. Pragmatism unstiffens all our theories, limbers them up and sets each one to work. | |
| From: William James (Pragmatism - eight lectures [1907], Lec 2) | |
| A reaction: This follows his criticism of the quest for 'solving names' - big words that give bogus solutions to problems. James's view is not the same as 'instrumentalism', though he would probably sympathise with that view. The defines theories badly. |
| 18985 | True thoughts are just valuable instruments of action [James] |
| Full Idea: The possession of true thoughts means everywhere the possession of invaluable instruments of action. | |
| From: William James (Pragmatism - eight lectures [1907], Lec 6) | |
| A reaction: It looks to me like we should distinguish 'active' and 'passive' instrumentalism. The passive version says there is no more to theories and truth than what instruments record. James's active version says truth is an instrument for doing things well. |
| 18982 | Pragmatism says all theories are instrumental - that is, mental modes of adaptation to reality [James] |
| Full Idea: The pragmatist view is that all our theories are instrumental, are mental modes of adaptation to reality, rather than revelations or gnostic answers to some divinely instituted world enigma. | |
| From: William James (Pragmatism - eight lectures [1907], Lec 5) | |
| A reaction: This treats instrumentalism as the pragmatic idea of theories as what works (and nothing more), with, presumably, no interest in grasping something called 'reality'. Presumably instrumentalism might have other motivations - such as fun. |
| 22654 | We can't know if the laws of nature are stable, but we must postulate it or assume it [James] |
| Full Idea: That nature will follow tomorrow the same laws that she follows today is a truth which no man can know; but in the interests of cognition as well as of action we must postulate or assume it. | |
| From: William James (The Sentiment of Rationality [1882], p.39) | |
| A reaction: The stability of nature is something to be assessed, not something taken for granted. If you arrive in a new city and it all seems quiet, you keep your fingers crossed and treat it as stable. But revolution or coup could be just round the corner. |
| 22656 | Trying to assess probabilities by mere calculation is absurd and impossible [James] |
| Full Idea: The absurd abstraction of an intellect verbally formulating all its evidence and carefully estimating the probability thereof solely by the size of a vulgar fraction, is as ideally inept as it is practically impossible. | |
| From: William James (The Sentiment of Rationality [1882], p.40) | |
| A reaction: James probably didn't know about Bayes, but this is directed at the Bayesian approach. My view is that full rational assessment of coherence is a much better bet than a Bayesian calculation. Factors must be weighted. |
| 22646 | We have a passion for knowing the parts of something, rather than the whole [James] |
| Full Idea: Alongside the passion for simplification …is the passion for distinguishing; it is the passion to be acquainted with the parts rather than to comprehend the whole. | |
| From: William James (The Sentiment of Rationality [1882], p.22) | |
| A reaction: As I child I dismantled almost every toy I was given. This seems to be the motivation for a lot of analytic philosophy, but Aristotle also tended to think that way. |
| 3232 | Abduction could have true data and a false conclusion, and may include data not originally mentioned [Rey] |
| Full Idea: Abduction moves from some data to a 'best explanation'. It is not deduction because the data could be true but the conclusion false, and it is not induction because the conclusion may involve data not mentioned in the premises. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], p.322) |
| 3128 | It's not at all clear that explanation needs to stop anywhere [Rey] |
| Full Idea: It's not at all clear that explanation needs to stop anywhere. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], Int.2) |
| 22652 | The mind has evolved entirely for practical interests, seen in our reflex actions [James] |
| Full Idea: It is far too little recognised how entirely the intellect is built up of practical interests. The theory of evolution is beginning to do very good service by its reduction of all mentality to the type of reflex action. | |
| From: William James (The Sentiment of Rationality [1882], p.34) | |
| A reaction: Hands evolved for manipulating tools end up playing the piano. Minds evolved for action can be afflicted with boredom. He's not wrong, but he is risking the etymological fallacy (origin = purpose). I take navigation to be the original purpose of mind. |
| 3136 | The three theories are reduction, dualism, eliminativism [Rey] |
| Full Idea: There are three main views regarding the ontology of mental phenomena: reductionism, dualism and eliminativism. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 1.1) | |
| A reaction: It is precisely this picture which is rejected by Davidson and co, who want something called 'property dualism', with a unique relationship which is labelled 'supervenient'. Unfortunately there is no analogy for it. Not even beauty and a statue. |
| 22651 | Dogs' curiosity only concerns what will happen next [James] |
| Full Idea: A dog's curiosity about the movements of his master or a strange object only extends as far as the point of what is going to happen next. | |
| From: William James (The Sentiment of Rationality [1882], p.31) | |
| A reaction: Good. A nice corrective to people like myself who are tempted to inflate animal rationality, in order to emphasise human evolutionary continuity with them. It is hard to disagree with his observation. But dogs do make judgements! True/false! |
| 9286 | Consciousness is not a stuff, but is explained by the relations between experiences [James] |
| Full Idea: Consciousness connotes a kind of external relation, and not a special stuff or way of being. The peculiarity of our experiences, that they not only are, but are known, is best explained by their relations to one another, the relations being experiences. | |
| From: William James (Does Consciousness Exist? [1904], §3) | |
| A reaction: This view has suddenly caught people's interest. It might be better than the higher/lower relationship, which seems to leave the basic problem untouched. Does a whole network of relations between experiences gradually 'add up' to consciousness? |
| 3141 | Is consciousness 40Hz oscillations in layers 5 and 6 of the visual cortex? [Rey] |
| Full Idea: Crick and Koch claim that visual consciousness is correlated with a 40Hz oscillation in layers five and six of the primary visual cortex. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 2.1) | |
| A reaction: Not many people seem to have been enthused by their proposal. The target is the NCC (Neural Correlate of Consciousness), but we would only accept that location if the 'oscillations' seemed in some way special. |
| 3148 | Dualist privacy is seen as too deep for even telepathy to reach [Rey] |
| Full Idea: The privacy that is a serious issue for the dualist is a peculiarly epistemic privacy that not even telepathy or brain fusions would seem to overcome. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 2.5.4) | |
| A reaction: This is a key idea in the traditional defence of dualism. I'm inclined to think that we are faced with deep privacy not because the mind is so hidden, but because the observer is trapped in NOT being the thing observed. In that sense, rocks are private. |
| 3164 | Intentional explanations are always circular [Rey] |
| Full Idea: There can seem to be no escape from the "intentional circle" - the use of one intentional idiom always seems to presuppose the use of another. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 3.3) | |
| A reaction: The best explanation of this is Conceptual Dualism (Papineau: Thinking about Consciousness). We are locked into dualist concepts because of our long-term ignorance about the brain. |
| 3138 | Arithmetic and unconscious attitudes have no qualia [Rey] |
| Full Idea: The contents of thoughts, beliefs and desires seem quite distinct from qualia. Arithmetic has no particular feeling attached to it, and Freud showed that many propositional attitudes have no feeling at all, as they are unconscious. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 1.1.2) | |
| A reaction: I don't think we should rule out 'pre-conscious' qualia. The fact that advanced human mental capacities like arithmetic have thinned out their qualia doesn't count against qualia being essential to normal mental life. |
| 3142 | Why qualia, and why this particular quale? [Rey] |
| Full Idea: If we allow as a brute fact that certain mental states possess conscious qualitative content, there is still the problem of explaining why they possess one content rather than another (why does this stimulus look RED?). | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 2.1) | |
| A reaction: This strikes me as the Really Hard Question. The Hard Question is merely 'why are creatures aware of their thoughts?' Personally I don't rule out finding a physical answer to the RHQ, and it is certainly not grounds for drifting into neo-dualism. |
| 3224 | If qualia have no function, their attachment to thoughts is accidental [Rey] |
| Full Idea: If qualia are non-functionally defined objects, then their attachment to their role in my thought would seem to be metaphysically accidental. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 11.4.2) | |
| A reaction: A rock at sea can cause a shipwreck without being defined as 'a shipwrecker'. It is, of course, tautological that if qualia have a 'role' in my thoughts, they must have causal powers, but 'function' is a much trickier concept. |
| 3227 | Are qualia a type of propositional attitude? [Rey] |
| Full Idea: Qualitative experience is just a particular species of propositional attitude. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 11.6.1) | |
| A reaction: This sounds very implausible. If I hear a loud and baffling noise, is a proposition instantly involved? When a subtle change of colour occurs in the sky at sunset, is that 'propositional'? Do slugs formulate propositions when they taste garlic? |
| 3226 | Are qualia irrelevant to explaining the mind? [Rey] |
| Full Idea: Phenomenal objects and properties are no more needed to explain the workings of our mind than are angels needed to explain the motion of the planets. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 11.6.1) | |
| A reaction: The question would be whether 'phenomenal properties' contained unique information, which could therefore influence behaviour. It is also a matter of exactly what you are trying to explain. |
| 3229 | If colour fits a cone mapping hue, brightness and saturation, rotating the cone could give spectrum inversion [Rey] |
| Full Idea: If colour can be modelled as a cone, with points mapped by hue, brightness and saturation, then a rotation could be isomorphic with the hues switched, so we may all experience different hues. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 11.7.1) | |
| A reaction: from Levine |
| 3223 | Self-consciousness may just be nested intentionality [Rey] |
| Full Idea: It is tempting to think that if a system has concepts for nested intentionality and first-person reflection, it has all that's needed for self-consciousness. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 11.2.2) | |
| A reaction: If there nothing more than nested intentionality in complex minds like ours, the top level of the nesting would still have a special status. And if the top level always seemed to stay the same while the lower levels changed, I'd probably call it the Self |
| 3162 | Experiments prove that people are often unaware of their motives [Rey] |
| Full Idea: Experiments have shown (Nisbett and Wilson 1977) that people's introspective knowledge is a lot less reliable than they suppose. People are sensitive to but entirely unaware of many factors that influence their social behaviour. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 3.2.2) | |
| A reaction: This type of observation rests on an overemphasis on the conscious mind. We are not conscious of liver events, or of deep buried brain events, both of which motivate us. We should only expect introspection to reveal what is fully conscious. |
| 3163 | Brain damage makes the unreliability of introspection obvious [Rey] |
| Full Idea: The most dramatic phenomena undermining the absolute reliability of introspection are those of blindsight and "anosognosia" (unawareness of one's own brain damage). | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 3.2.2) | |
| A reaction: It might depend on what you expected introspection to reveal. If you only expected it to tell you about your consciousness, it would be unreasonable to expect knowledge of blindsight information by introspection. |
| 3195 | If reason could be explained in computational terms, there would be no need for the concept of 'free will' [Rey] |
| Full Idea: If a computational account of reasoning processes could be given, then there is no need to settle the issue of "free will", as reason could get along without it. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 8.6) |
| 3196 | Free will isn't evidence against a theory of thought if there is no evidence for free will [Rey] |
| Full Idea: We don't need arguments to show that if there were free will then computational accounts of the mind would be inadequate; what is needed is good evidence that there actually exists such free will in the first place. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 8.6) |
| 3180 | Maybe behaviourists should define mental states as a group [Rey] |
| Full Idea: Defining most mental states seems to requiring citing other mental states - but perhaps behaviourists can define them all simultaneously | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 5.3) | |
| A reaction: This is an interesting strategy for trying to avoid the well known circularity of attempting to define mental states in behavioural terms. Behaviourism won't go away. |
| 3165 | Behaviourism is eliminative, or reductionist, or methodological [Rey] |
| Full Idea: There are three different views concerning behaviourism - the 'radical' view, which aims at eliminativism, the 'analytical' view, which is a reductionist enterprise, and the 'methodological' view, somewhere between the two. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 4) | |
| A reaction: The first appears to be ontological, the second about relationships between areas of our language, and the third epistemological. You could attempt language reduction because we can only know behaviour, because that's all there is. |
| 3167 | Animals don't just respond to stimuli, they experiment [Rey] |
| Full Idea: Animals exhibit 'spontaneous alteration' in their behaviour (e.g. varying the route to the food), or improvisation (finding short cuts instead of following training). They use mental maps, or dead reckoning, not just conditioned responses. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 4.1.4) | |
| A reaction: If we can't even get a decent behaviourist account of animal behaviour, presumably the chances for humans look even less good. 'Black box' behaviourism, rather than the eliminativist version, might allow internal mechanisms to modify responses. |
| 3173 | How are stimuli and responses 'similar'? [Rey] |
| Full Idea: Radical behaviourists say animals emit "similar" responses to "similar" reinforcements, but that is empty without specifying in what respect there is a similarity. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 4.3) | |
| A reaction: The point is that when you try to specify the similarity you are (supposedly) forced to use mental language to make the distinctions, thus contradicting behaviourism. It is not, though, self-evidently impossible to give a behaviourist specification. |
| 3179 | Behaviour is too contingent and irrelevant to be the mind [Rey] |
| Full Idea: The two main anti-behaviourist intuitions are that mind and behaviour only relate contingently, and that for much mental life (thinking, emotion) the resulting behaviour seems unimportant. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 5.3) | |
| A reaction: Attractive intuitions, but not unquestionable. Since no two states of mind are ever fully identical, we can never test whether the resulting behaviour arises contingently or necessarily. The second point underestimates the physicality of mental life. |
| 3186 | If a normal person lacked a brain, would you say they had no mind? [Rey] |
| Full Idea: If many otherwise ordinary people turned out to have skulls which were empty or filled with oatmeal, would that mean that they didn't have minds? | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 7.1.4) | |
| A reaction: That's a John Locke sort of question, implying that 'persons' are logically independent of their implementation. Personally I would search for a radio receiver, because oatmeal is implausible as a thinker. |
| 3127 | Dualism and physicalism explain nothing, and don't suggest any research [Rey] |
| Full Idea: Neither dualism nor physicalism provides much serious explanation of any mental phenomena, or even much in the way of a program of research. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], Int.2) | |
| A reaction: I'm not sure if people who demand an "explanation of mental phenomena" are quite clear about what it is they want. God might just say "Mental phenomena are just brain events from the brain's point of view". |
| 3188 | Homuncular functionalism (e.g. Freud) could be based on simpler mechanical processes [Rey] |
| Full Idea: So-called 'homuncular functionalism' (such as Freud's or Plato's internal struggles of the soul) needn't lead to an infinite regress if eventually the homunculi become so stupid they could be replaced by a machine. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 7.2.2) | |
| A reaction: from Fodor |
| 3216 | Is the room functionally the same as a Chinese speaker? [Rey] |
| Full Idea: The question for a computational-representation theory about the Chinese Room is: is what is happening inside the room functionally equivalent to what is happening inside a normal Chinese speaker? | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 10.2.1) | |
| A reaction: Certainly the Room lacks morality ('how can I torture my sister?'). It won't spot connections between recent questions. It won't ask itself questions. It will take years to spot absurd questions. |
| 3220 | Searle is guilty of the fallacy of division - attributing a property of the whole to a part [Rey] |
| Full Idea: You should no more attribute understanding of Chinese to this one part of the system than you should ascribe the properties of the entire British Empire to Queen Victoria. This is the fallacy of division. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 10.2.3) | |
| A reaction: This very nicely pinpoints what is wrong with the Chinese Room argument (nice analogy, too). If you carefully introspect what is involved when you 'understand' something, it is immensely complex, though it feels instant and simple. |
| 3206 | One computer program could either play chess or fight a war [Rey] |
| Full Idea: It is always possible to provide incompatible interpretations of formal theories, so that a computer could use the same program one day to play chess, the next to fight a war. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 9.1.3) | |
| A reaction: This seems to present a huge gulf between human chess players (who 'understand' what they are doing) and machines, but I don't accept it. Giving the machine cameras and multi-level software would fix it. |
| 9285 | 'Consciousness' is a nonentity, a mere echo of the disappearing 'soul' [James] |
| Full Idea: 'Consciousness' is the name of a nonentity. ..Those who cling to it are clinging to a mere echo, the faint rumour left behind by the disappearing 'soul' upon the air of philosophy. ..I deny that it stands for an entity, but it does stand for a function. | |
| From: William James (Does Consciousness Exist? [1904], Intro) | |
| A reaction: This kind of view is often treated as being preposterous, but I think it is correct. No one is denying the phenomenology, but it is the ontology which is at stake. Either you are a substance dualist, or mind must be eliminated as an 'entity'. |
| 3140 | If you explain water as H2O, you have reduced water, but not eliminated it [Rey] |
| Full Idea: Reduction is not the same as elimination; if chemists reduce water to H2O, or biologists reduce life to a complex chemical process, they have not shown that they don't exist. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 1.2.1) | |
| A reaction: Depends what you mean by 'elimination'. It is important to be clear whether you are eliminating something from life, or from strict philosophical ontology. Ontologists never mention mountains. |
| 3134 | Human behaviour can show law-like regularity, which eliminativism can't explain [Rey] |
| Full Idea: There is clear evidence against eliminative materialism in the law-like correlations found among millions of answers in standardised school tests, for which it can give no explanation. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], Int.3) | |
| A reaction: Not very persuasive. If neural networks got involved in complex competitions with one another, you would expect them to evolve similar tactics. |
| 3200 | Pattern recognition is puzzling for computation, but makes sense for connectionism [Rey] |
| Full Idea: Connectionism is a way of capturing the holism of pattern recognition, as stressed by many critics of computational theories of mind. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 8.8) | |
| A reaction: I am drawn to the idea that arithmetic derives from pattern recognition, and the latter is basic to all minds (a kind of instant unthinking induction), so this seems to me a win for connectionism. |
| 3201 | Connectionism explains well speed of perception and 'graceful degradation' [Rey] |
| Full Idea: Connectionism is better than other AI strategies at capturing the extraordinary swiftness of perception, and of degrading in a 'graceful' way. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 8.8) | |
| A reaction: A good theory had better capture the extraordinary swiftness of perception. Also the swiftness of recognition. Compare seeing a surprising old friend in a crowd, and recognising the person you are looking for. |
| 3202 | Connectionism explains irrationality (such as the Gamblers' Fallacy) quite well [Rey] |
| Full Idea: Connectionism offers promising accounts of irrational behaviour, such as people's bias towards positive instances, and their tendency to fall for the gamblers' fallacy. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 8.8) | |
| A reaction: That is strong support, because the chances of a computational robot having such tendencies is virtually nil, but all humans have the biases referred to (even philosophers). |
| 3199 | Connectionism assigns numbers to nodes and branches, and plots the outcomes [Rey] |
| Full Idea: In connectionism, each node is given an activation level, and each branch a weight, according to possible degree of effect. This results in 'excitatory' and 'inhibitory' connections. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 8.8) | |
| A reaction: Whether such a system could ever be 'conscious' is not the only interesting question. What could such a system do? Could it ever be good at philosophy? |
| 3150 | Can identity explain reason, free will, non-extension, intentionality, subjectivity, experience? [Rey] |
| Full Idea: Eight properties of mind are problems for the identity theory: rationality, free will, spatiality, privacy, intentionality, essential mentality, subjective content, and the explanatory gap. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 2.7) | |
| A reaction: The list could go on: poetry, creativity, love, normativity... Actually, these are problems for every theory. |
| 3129 | Physicalism offers something called "complexity" instead of mental substance [Rey] |
| Full Idea: In physicalism the "ghost in the machine" is merely replaced by the "complexity" in it. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], Int.2) | |
| A reaction: This is nonsense. No one thinks that mere complexity generates consciousness. The assumption is that we would begin to understand the mind only if we could somehow map the connections of the brain. |
| 3139 | Some attitudes are information (belief), others motivate (hatred) [Rey] |
| Full Idea: Propositional attitudes divide into two broad types: neutral informational ones (belief, suspicion, imagining), and directional ones which motivate an agent (preference, desire, hate). | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 1.1.2) | |
| A reaction: Since suspicions are motivating, and preferences are informational, this is not a very sharp distinction. An alternative would be to say that there is one type, and sometimes the will gets involved. |
| 23981 | Rage is inconceivable without bodily responses; so there are no disembodied emotions [James] |
| Full Idea: Can one fancy a state of rage and picture no flushing of the face, no dilation of the nostrils, no clenching of the teeth, no impulse to vigorous action? …A purely disembodied human emotion is a nonentity. | |
| From: William James (What is an Emotion? [1884], p.194), quoted by Peter Goldie - The Emotions 3 'Bodily' | |
| A reaction: Plausible for rage, but less so for irritation or admiration. Goldie thinks James is wrong. James says if intellectual feelings don't become bodily then they don't qualify as emotions. No True Scotsman! |
| 22650 | How can the ground of rationality be itself rational? [James] |
| Full Idea: Can that which is the ground of rationality in all else be itself properly called rational? | |
| From: William James (The Sentiment of Rationality [1882], p.25) | |
| A reaction: This is the perennial problem in deciding grounds, and in deciding what to treat as primitive. The stoics see the whole of nature as rational. Cf how can the ground of what is physical be itself physical? |
| 22643 | It seems that we feel rational when we detect no irrationality [James] |
| Full Idea: I think there are very good grounds for upholding the view that the feeling of rationality is constituted merely by the absence of any feelings of irrationality. | |
| From: William James (The Sentiment of Rationality [1882], p.20) | |
| A reaction: A very interesting proposal. Nothing is more basic to logic (well, plausible versions of logic) than the principle of non-contradiction - perhaps because it is the foundation of our natural intellectual equipment. |
| 3171 | Children speak 90% good grammar [Rey] |
| Full Idea: Ninety percent of most young children's utterances are grammatical. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 4.2.4) | |
| A reaction: This is good evidence for some sort of innate element in the grammar of language. But the accurate grammar is not in a particular language. Good communication must be the driving force in all this. |
| 3174 | Good grammar can't come simply from stimuli [Rey] |
| Full Idea: Grammatical sensitivity is in no way a physical property of the stimulus, and we can't imagine how to build a device which would produce grammatical structures in response to the environment. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 4.3) | |
| A reaction: You could try to program it with a set of (say) Aristotelian categories, and mechanisms to sort the environment accordingly. It then has to query its database, in response to practical needs. A doddle. |
| 3213 | Animals may also use a language of thought [Rey] |
| Full Idea: The language of thought need not only be confined to creatures which speak a natural language. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 10.1.1) | |
| A reaction: I take it as axiomatic that our brains are no different in principles and fundamental mechanics from the lowliest of creatures. See Idea 7509. |
| 3170 | We train children in truth, not in grammar [Rey] |
| Full Idea: Very young children have been shown (Brown and Halon 1970) to be 'reinforced' not for their grammar but for the informational content of what they say. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 4.2.1) | |
| A reaction: This is what you would expect. It doesn't follow that the grammar comes from innate mechanisms, because the pressure to get the information right could impose increasing accuracy in grammar. |
| 3215 | Images can't replace computation, as they need it [Rey] |
| Full Idea: Processing of images and mental models seems to require, and therefore is unlikely to replace, computation and representation. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 10.1.2) | |
| A reaction: A good point. If you are a fan of mental imagery, you still have to explain how we can hold an image, or recall it, or manipulate it. I always, I don't know why, wince at the thought of 'computations' among neurons. |
| 3194 | CRTT is good on deduction, but not so hot on induction, abduction and practical reason [Rey] |
| Full Idea: The computational/representational theory of thought has given a good account of deduction, but mechanical theories of induction, abduction and practical reason are needed in order to make a machine which could reason. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 8.5) | |
| A reaction: This is the best analysis of rationality that I have found (four components: deduction, induction, abduction, practical reason). I can think of nothing to add, and certainly none of these should be omitted. |
| 3147 | Problem-solving clearly involves manipulating images [Rey] |
| Full Idea: Recent experiments (Shepard 1982) suggest people have imagistic representations they inspect when solving problems. In comparing two rotated images, the time for comparison varies with the angle of rotation. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 2.5.3) | |
| A reaction: This doesn't prove that they are slowly rotating something. It may just be harder to make the leap to the new shape, when it is 'further away'. Picturing a 20-sided figure, we don't add sides one-by-one. |
| 3175 | Animals map things over time as well as over space [Rey] |
| Full Idea: To map things like food over time, animals must somehow represent events as having temporal properties, and somehow store those representations ready for later use. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 4.3) | |
| A reaction: If the mechanisms for doing this are basic, then so is the ontology. Objects must be categorised, properties spotted, time-spans correlated etc. 'Represent' needs to be sharp to be useful. |
| 3207 | Simple externalism is that the meaning just is the object [Rey] |
| Full Idea: The oldest version of the externalist theory of meaning is the Fido/Fido theory, according to which the meaning of a representation is the object for which it stands. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 9.2) | |
| A reaction: Modern baptismal theories of reference seem to have taken us back to this, for distinct individuals such as Aristotle, or natural kinds like gold. What, though, does 'Fido' mean to me? Asthma! |
| 18975 | We return to experience with concepts, where they show us differences [James] |
| Full Idea: Concepts for the pragmatist are things to come back into experience with, things to make us look for differences. | |
| From: William James (Pragmatism - eight lectures [1907], Lec 3) | |
| A reaction: That's good. I like both halves of this. Experience gives us the concepts, but then we 'come back' into experience equipped with them. Presumably animals can look for differences, but concepts enhance that hugely. Know the names of the flowers. |
| 3176 | Anything bears a family resemblance to a game, but obviously not anything counts as one [Rey] |
| Full Idea: Anything bears a family resemblance to a game, but obviously not anything counts as one. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 4.3) |
| 8917 | The Way of Abstraction used to say an abstraction is an idea that was formed by abstracting [Rosen] |
| Full Idea: The simplest version of the Way of Abstraction would be to say that an object is abstract if it is a referent of an idea that was formed by abstraction, but this is wedded to an outmoded philosophy of mind. | |
| From: Gideon Rosen (Abstract Objects [2001], 'Way of Abs') | |
| A reaction: This presumably refers to Locke, who wields the highly ambiguous term 'idea'. But if we sort out that ambiguity (by using modern talk of mental events, concepts and content?) we might reclaim the view. But do we have a 'genetic fallacy' here? |
| 8912 | Nowadays abstractions are defined as non-spatial, causally inert things [Rosen] |
| Full Idea: If any characterization of the abstract deserves to be regarded as the modern standard one, it is this: an abstract entity is a non-spatial (or non-spatiotemporal) causally inert thing. This view presents a number of perplexities... | |
| From: Gideon Rosen (Abstract Objects [2001], 'Non-spat') | |
| A reaction: As indicated in other ideas, the problem is that some abstractions do seem to be located somewhere in space-time, and to have come into existence, and to pass away. I like 'to exist is to have causal powers'. See Ideas 5992 and 8300. |
| 8913 | Chess may be abstract, but it has existed in specific space and time [Rosen] |
| Full Idea: The natural view of chess is not that it is a non-spatiotemporal mathematical object, but that it was invented at a certain time and place, that it has changed over the years, and so on. | |
| From: Gideon Rosen (Abstract Objects [2001], 'Non-spat') | |
| A reaction: This strikes me as being undeniable, and being an incredibly important point. Logicians seem to want to subsume things like games into the highly abstract world of logic and numbers. In fact the direction of explanation should be reversed. |
| 8914 | Sets are said to be abstract and non-spatial, but a set of books can be on a shelf [Rosen] |
| Full Idea: It is thought that sets are abstract, abstract objects do not exist in space, so sets must not exist in space. But it is not unnatural to say that a set of books is located on a certain shelf in the library. | |
| From: Gideon Rosen (Abstract Objects [2001], 'Non-spat') | |
| A reaction: The arguments against non-spatiality of abstractions seem to me to be conclusive. Not being able to assign a location to the cosine function is on a par with not knowing where my thoughts are located in my brain. |
| 8916 | Conflating abstractions with either sets or universals is a big claim, needing a big defence [Rosen] |
| Full Idea: The Way of Conflation account of abstractions (identifying them sets or with universals) is now relatively rare. The claim sets or universals are the only abstract objects would amount to a substantive metaphysical thesis, in need of defence. | |
| From: Gideon Rosen (Abstract Objects [2001], 'Way of Con') | |
| A reaction: If you produce a concept like 'mammal' by psychological abstraction, you do seem to end up with a set of things with shared properties, so this approach is not silly. I can't think of any examples of abstractions which are not sets or universals. |
| 8918 | Functional terms can pick out abstractions by asserting an equivalence relation [Rosen] |
| Full Idea: On Frege's suggestion, functional terms that pick out abstract expressions (such as 'direction' or 'equinumeral') have a typical form of f(a) = f(b) iff aRb, where R is an equivalence relation, a relation which is reflexive, symmetric and transitive. | |
| From: Gideon Rosen (Abstract Objects [2001], 'Way of Abs') | |
| A reaction: [Wright and Hale are credited with the details] This has become the modern orthodoxy among the logically-minded. Examples of R are 'parallel' or 'just as many as'. It picks out an 'aspect', which isn't far from the old view. |
| 8919 | Abstraction by equivalence relationships might prove that a train is an abstract entity [Rosen] |
| Full Idea: It seems possible to define a train in terms of its carriages and the connection relationship, which would meet the equivalence account of abstraction, but demonstrate that trains are actually abstract. | |
| From: Gideon Rosen (Abstract Objects [2001], 'Way of Abs') | |
| A reaction: [Compressed. See article for more detail] A tricky example, but a suggestive line of criticism. If you find two physical objects which relate to one another reflexively, symmetrically and transitively, they may turn out to be abstract. |
| 3181 | A one hour gap in time might be indirectly verified, but then almost anything could be [Rey] |
| Full Idea: You couldn't directly verify that the whole universe had stopped for one hour, but you might indirectly verify it (by prediction) - but then almost anything could be very indirectly verified. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 5.4) | |
| A reaction: Does indirect verification include time travel? Or perfect knowledge of quantum theory, and total knowledge of quantum states. Laplace's Hypothesis. |
| 3204 | The meaning of "and" may be its use, but not of "animal" [Rey] |
| Full Idea: The view that the meaning of language of thought expressions is based on their conceptual role (derived from Wittgenstein's idea of meaning as use), is most plausible for the logical connectives like "and", but implausible for, say, "animal". | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 9.1.2) | |
| A reaction: It was the logical connectives that got LW started on this track. If it doesn't work for 'animal' then does that mean we need two different theories? |
| 3205 | Semantic holism means new evidence for a belief changes the belief, and we can't agree on concepts [Rey] |
| Full Idea: Semantic holism is a desperate measure. Belief content would be continually changed by new beliefs, evidence for a belief would change the target belief, and no two people would ever agree on concepts. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 9.1.2) | |
| A reaction: It is far more plausible to say language is a bit on the holistic side. Total holism is mad. |
| 20300 | Externalist synonymy is there being a correct link to the same external phenomena [Rey] |
| Full Idea: Externalists are typically committed to counting expressions as 'synonymous' if they happen to be linked in the right way to the same external phenomena, even if a thinker couldn't realise that they are by reflection alone. | |
| From: Georges Rey (The Analytic/Synthetic Distinction [2013], 4.2) | |
| A reaction: [He cites Fodor] Externalists always try to link to concrete things in the world, but most of our talk is full of generalities, abstractions and fiction which don't link directly to anything. |
| 3209 | Causal theories of reference (by 'dubbing') don't eliminate meanings in the heads of dubbers [Rey] |
| Full Idea: Causal histories may have some role to play in a theory of reference, but the chain of causation requires internal characterisations at each stage, and the original dubber had one thing rather than another in mind when dubbing. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 9.2.1) | |
| A reaction: The modern view of direct reference seems to prefer social context rather than a complete causal chain. |
| 3210 | If meaning and reference are based on causation, then virtually everything has meaning [Rey] |
| Full Idea: What is special about meaning? If meaning and reference are just the result of causal chains, almost everything will mean something, since almost everything is reliably caused by something. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 9.2.2) | |
| A reaction: It would be insane to think that all causal events produced meanings. It is probably better not to mention causation at all when discussing meaning. |
| 3149 | Referential Opacity says truth is lost when you substitute one referring term ('mother') for another ('Jocasta') [Rey] |
| Full Idea: Referential Opacity says you cannot preserve truth if you substitute one referring term for another ('Oedipus desires Jocasta', 'Oedipus desires his mother'). | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 2.5.6) | |
| A reaction: ….That is, in the context of expressing a propositional attitude. 'Oedipus desired his mother' was true. This idea requires some ignorance on the part of the person expressing the thought. |
| 20294 | 'Married' does not 'contain' its symmetry, nor 'bigger than' its transitivity [Rey] |
| Full Idea: If Bob is married to Sue, then Sue is married to Bob. If x bigger than y, and y bigger than z, x is bigger than z. The symmetry of 'marriage' or transitivity of 'bigger than' are not obviously 'contained in' the corresponding thoughts. | |
| From: Georges Rey (The Analytic/Synthetic Distinction [2013], 1.2) | |
| A reaction: [Also 'if something is red, then it is coloured'] This is a Fregean criticism of Kant. It is not so much that Kant was wrong, as that the concept of analyticity is seen to have a much wider application than Kant realised. Especially in mathematics. |
| 20293 | Analytic judgements can't be explained by contradiction, since that is what is assumed [Rey] |
| Full Idea: Rejecting 'a married bachelor' as contradictory would seem to have no justification other than the claim that 'All bachelors are unmarried is analytic, and so cannot serve to justify or explain that claim. | |
| From: Georges Rey (The Analytic/Synthetic Distinction [2013], 1.2) | |
| A reaction: Rey is discussing Frege's objection to Kant (who tried to prove the necessity of analytic judgements, on the basis of the denial being a contradiction). |
| 20297 | Analytic statements are undeniable (because of meaning), rather than unrevisable [Rey] |
| Full Idea: What's peculiar about the analytic is that denying it seem unintelligible. Far from unrevisability explaining analyticity, it seems to be analyticitiy that explains unrevisability; we only balk at denying unmarried bachelors because that's what it means! | |
| From: Georges Rey (The Analytic/Synthetic Distinction [2013], 3.7) | |
| A reaction: This is a criticism of Quine, who attacked analyticity when it is understood as unrevisability. Obviously we could revise the concept of 'bachelor', if our marriage customs changed a lot. Rey seems right here. |
| 20301 | The meaning properties of a term are those which explain how the term is typically used [Rey] |
| Full Idea: It may be that the meaning properties of a term are the ones that play a basic explanatory role with regard to the use of the term generally, the ones in virtue ultimately of which a term is used with that meaning. | |
| From: Georges Rey (The Analytic/Synthetic Distinction [2013], 4.3) | |
| A reaction: [He cites Devitt 1996, 2002, and Horwich 1998, 2005) I spring to philosophical life whenever I see the word 'explanatory', because that is the point of the whole game. They are pointing to the essence of the concept (which is explanatory, say I). |
| 20302 | An intrinsic language faculty may fix what is meaningful (as well as grammatical) [Rey] |
| Full Idea: The existence of a separate language faculty may be an odd but psychologically real fact about us, and it may thereby supply a real basis for commitments about not only what is or is not grammatical, but about what is a matter of natural language meaning. | |
| From: Georges Rey (The Analytic/Synthetic Distinction [2013], 4.4) | |
| A reaction: This is the Chomskyan view of analytic sentences. An example from Chomsky (1977:142) is the semantic relationships of persuade, intend and believe. It's hard to see how the secret faculty on its own could do the job. Consensus is needed. |
| 20303 | Research throws doubts on the claimed intuitions which support analyticity [Rey] |
| Full Idea: The movement of 'experimental philosophy' has pointed to evidence of considerable malleability of subject's 'intuitions' with regard to the standard kinds of thought experiments on which defenses of analytic claims typically rely. | |
| From: Georges Rey (The Analytic/Synthetic Distinction [2013], 4.4) | |
| A reaction: See Cappelen's interesting attack on the idea that philosophy relies on intuitions, and hence his attack on experimental philosophy. Our consensus on ordinary English usage hardly qualifies as somewhat vague 'intuitions'. |
| 14099 | 'Bachelor' consists in or reduces to 'unmarried' male, but not the other way around [Rosen] |
| Full Idea: It sounds right to say that Fred's being a bachelor consists in (reduces to) being an unmarried male, but slightly off to say that Fred's being an unmarried male consists in (or reduces to) being a bachelor. There is a corresponding explanatory asymmetry. | |
| From: Gideon Rosen (Metaphysical Dependence [2010], 10) | |
| A reaction: This emerging understanding of the asymmetry of the idea shows that we are not just dealing with a simple semantic identity. Our concepts are richer than our language. He adds that a ball could be blue in virtue of being cerulean. |
| 20299 | If we claim direct insight to what is analytic, how do we know it is not sub-consciously empirical? [Rey] |
| Full Idea: How in the end are we going to distinguish claims or the analytic as 'rational insight', 'primitive compulsion', inferential practice or folk belief from merely some deeply held empirical conviction, indeed, from mere dogma. | |
| From: Georges Rey (The Analytic/Synthetic Distinction [2013], 4.1) | |
| A reaction: This is Rey's summary of the persisting Quinean challenge to analytic truths, in the face of a set of replies, summarised by the various phrases here. So do we reject a dogma of empiricism, by asserting dogmatic empiricism? |
| 3169 | A simple chaining device can't build sentences containing 'either..or', or 'if..then' [Rey] |
| Full Idea: Bifurcated logical particles (either/or, if/then) are in principle beyond the power of any local chaining device to build sentences. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 4.2.1) | |
| A reaction: True in natural languages, but not in formal ones? If P then either if-Q-then-R or if-S-then-T. Is that chaining? If rain, then if light then puddles, or if heavy then floods. Hm. |
| 22660 | Evolution suggests prevailing or survival as a new criterion of right and wrong [James] |
| Full Idea: The philosophy of evolution offers us today a new criterion, which is objective and fixed, as an ethical test between right and wrong: That is to be called good which is destined to prevail or survive. | |
| From: William James (The Sentiment of Rationality [1882], p.44) | |
| A reaction: Perceptive for its time. Herbert Spencer may have suggested the idea. James dismisses it, because it implies a sort of fatalism, whereas genuine moral choices are involved in what survives. |
| 3221 | Our desires become important when we have desires about desires [Rey] |
| Full Idea: What gives people's desires certain moral importance is the fact that they have desires about those desires. | |
| From: Georges Rey (Contemporary Philosophy of Mind [1997], 11.1) | |
| A reaction: from Frankfurt |
| 6570 | Imagine millions made happy on condition that one person suffers endless lonely torture [James] |
| Full Idea: Consider a case in which millions could be made permanently happy on the one simple condition that a certain lost soul on the far-off edge of things should lead a life of lonely torture. | |
| From: William James (The Will to Believe [1896], p.188), quoted by Robert Fogelin - Walking the Tightrope of Reason Ch.2 | |
| A reaction: This seems to be one of the earliest pinpointings of a key problem with utilitiarianism, which is that other values than happiness (in this case, fairness) seem to be utterly overruled. If we ignore fairness, why shouldn't we ignore happiness? |
| 22645 | Understanding by means of causes is useless if they are not reduced to a minimum number [James] |
| Full Idea: The knowledge of things by their causes, which is often given as a definition of rational knowledge, is useless unless the causes converge to a minimum number, while still producing the maximum number of effects. | |
| From: William James (The Sentiment of Rationality [1882], p.21) | |
| A reaction: This is certainly the psychological motivation for trying to identify 'the' cause of something, but James always tries to sell such things as subjective. 'Useless' to one person is a subjective criterion; useless to anyone is much more objective. |
| 18854 | The MRL view says laws are the theorems of the simplest and strongest account of the world [Rosen] |
| Full Idea: According to the Mill-Ramsey-Lewis account of the laws of nature, a generalisation is a law just in case it is a theorem of every true account of the actual world that achieves the best overall balance of simplicity and strength. | |
| From: Gideon Rosen (The Limits of Contingency [2006], 08) | |
| A reaction: The obvious objection is that many of the theorems will be utterly trivial, and that is one thing that the laws of nature are not. Unless you are including 'metaphysical laws' about very very fundamental things, like objects, properties, relations. |
| 14098 | An acid is just a proton donor [Rosen] |
| Full Idea: To be an acid just is to be a proton donor. | |
| From: Gideon Rosen (Metaphysical Dependence [2010], 10) | |
| A reaction: My interest here is in whether we can say that we have found the 'essence' of an acid - so we want to know whether something 'deeper' explains the proton-donation. I suspect not. Being a proton donor happens to have a group of related consequences. |
| 18980 | If there is a 'greatest knower', it doesn't follow that they know absolutely everything [James] |
| Full Idea: The greatest knower of them all may yet not know the whole of everything, or even know what he does know at one single stroke: - he may be liable to forget. | |
| From: William James (Pragmatism - eight lectures [1907], Lec 4) | |
| A reaction: And that's before you get to the problem of how the greatest knower could possibly know whether or not they knew absolutely everything, or whether there might be some fact which was irremediably hidden from them. |
| 18978 | It is hard to grasp a cosmic mind which produces such a mixture of goods and evils [James] |
| Full Idea: We can with difficulty comprehend the character of a cosmic mind whose purposes are fully revealed by the strange mixture of good and evils that we find in this actual world's particulars. | |
| From: William James (Pragmatism - eight lectures [1907], Lec 3) | |
| A reaction: And, of course, what counts as 'goods' or 'evils' seems to have a highly relative aspect to it. To claim that really it is all good is massive hope based on flimsy evidence. |
| 18991 | If the God hypothesis works well, then it is true [James] |
| Full Idea: On pragmatistic principles, if the hypothesis of God works satisfactorily in the widest sense of the word, it is true. | |
| From: William James (Pragmatism - eight lectures [1907], Lec 8) | |
| A reaction: The truth of God's existence certainly is a challenging test case for the pragmatic theory of truth, and James really bites the bullet here. Pragmatism may ultimately founder on the impossibility of specifying what 'works satisfactorily' means. |
| 18977 | The wonderful design of a woodpecker looks diabolical to its victims [James] |
| Full Idea: To the grub under the bark the exquisite fitness of the woodpecker's organism to extract him would certainly argue a diabolical designer. | |
| From: William James (Pragmatism - eight lectures [1907], Lec 3) | |
| A reaction: What an elegant sentence! The huge problem for religious people who accept (probably reluctantly) evolution by natural selection is the moral nature of the divine being who could use such a ruthless method of design. |
| 18979 | Things with parts always have some structure, so they always appear to be designed [James] |
| Full Idea: The parts of things must always make some definite resultant, be it chaotic or harmonious. When we look at what has actually come, the conditions must always appear perfectly designed to ensure it. | |
| From: William James (Pragmatism - eight lectures [1907], Lec 3) | |
| A reaction: In so far as the design argument is an analogy with human affairs, we can't deny that high levels of order suggest an organising mind, and mere chaos suggests a coincidence of unco-ordinated forces. |
| 18976 | Private experience is the main evidence for God [James] |
| Full Idea: I myself believe that the evidence for God lies primarily in inner personal experience. | |
| From: William James (Pragmatism - eight lectures [1907], Lec 3) | |
| A reaction: There is not much you can say to someone who claims incontrovertible evidence which is utterly private to themselves. Does total absence of private religious experience count as evidence on the subject? |
| 22653 | Early Christianity says God recognises the neglected weak and tender impulses [James] |
| Full Idea: In what did the emancipating message of primitive Christianity consist but in the announcement that God recognizes those weak and tender impulses which paganism had so rudely overlooked. | |
| From: William James (The Sentiment of Rationality [1882], p.36) | |
| A reaction: Nietzsche says these are the virtues of a good slave. Previous virtues were dominated by military needs, but the new virtues are those of large cities, where communal living with strangers is the challenge. |
| 18990 | Nirvana means safety from sense experience, and hindus and buddhists are just afraid of life [James] |
| Full Idea: Nirvana means safety from the everlasting round of adventures of which the world of sense consists. The hindoo and the buddhist for this is essentially their attitude, are simply afraid, afraid of more experience, afraid of life. | |
| From: William James (Pragmatism - eight lectures [1907], Lec 8) | |
| A reaction: Wonderfully American! From what I have seen of eastern thought, including Taoism, I agree with James, in general. There is a rejection of knowledge and of human life which I find shocking. I suspect it is a defence mechanism for downtrodden people. |
