100 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. |
12027 | There must be a plausible epistemological theory alongside any metaphysical theory [Forbes,G] |
Full Idea: No metaphysical account which renders it impossible to give a plausible epistemological theory is to be countenanced. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 9.1) | |
A reaction: It is hard to object to this principle, though we certainly don't want to go verificationist, and thus rule out speculations about metaphysics which are beyond any possible knowledge. Some have tried to prove that something must exist (e.g. Jacquette). |
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]. |
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. |
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. |
18335 | There are five problems which the truth-maker theory might solve [Rami] |
Full Idea: It is claimed that truth-makers explain universals, or ontological commitment, or commitment to realism, or to the correspondence theory of truth, or to falsify behaviourism or phenomenalism. | |
From: Adolph Rami (Introduction: Truth and Truth-Making [2009], 04) | |
A reaction: [compressed] This expands the view that truth-making is based on its explanatory power, rather than on its intuitive correctness. I take the theory to presuppose realism. I don't believe in universals. It marginalises correspondence. Commitment is good! |
18334 | The truth-maker idea is usually justified by its explanatory power, or intuitive appeal [Rami] |
Full Idea: The two strategies for justifying the truth-maker principle are that it has an explanatory role (for certain philosophical problems and theses), or that it captures the best philosophical intuition of the situation. | |
From: Adolph Rami (Introduction: Truth and Truth-Making [2009], 04) | |
A reaction: I would go for 'intuitive', but not in the sense of a pure intuition, but with 'intuitive' as a shorthand for overall coherence. To me the appeal of truth-maker is its place in a naturalistic view of reality. I love explanation, but not here. |
18339 | The truth-making relation can be one-to-one, or many-to-many [Rami] |
Full Idea: The truth-making relation can be one-to-one, or many-many. In the latter case, different truths may have the same truth-maker, and one truth may have different truth-makers. | |
From: Adolph Rami (Introduction: Truth and Truth-Making [2009], 05) | |
A reaction: 'There is at least one cat' obviously has many possible truth-makers. Many statements will be made true by the mere existence of a particular cat (such as 'there is an animal in the room' and 'there is a cat in the room'). Many-many wins? |
18333 | Central idea: truths need truthmakers; and possibly all truths have them, and makers entail truths [Rami] |
Full Idea: The main full-blooded truth-maker principle is that x is true iff there is a y that is its truth-maker. This implies the principles that if x is true x has a truth-maker, and the principle that if x has a truth-maker then x is true. | |
From: Adolph Rami (Introduction: Truth and Truth-Making [2009], 03) | |
A reaction: [compressed] Rami calls the second principle 'maximalism' and the third principle 'purism'. To reject maximalism is to hold a more restricted version of truth-makers. That is, the claim is that lots of truths have truth-makers. |
18342 | Most theorists say that truth-makers necessitate their truths [Rami] |
Full Idea: Most truth-maker theorists regard the necessitation of a truth by a truth-maker as a necessary condition of truth-making. | |
From: Adolph Rami (Introduction: Truth and Truth-Making [2009], 07) | |
A reaction: It seems to me that reality is crammed full of potential truth-makers, but not crammed full of truths. If there is no thinking in the universe, then there are no truths. If that is false, then what sort of weird beast is a 'truth'? |
18340 | It seems best to assume different kinds of truth-maker, such as objects, facts, tropes, or events [Rami] |
Full Idea: Truthmaker anti-monism holds the view that there are truth-makers of different kinds. For example, objects, facts, tropes or events can all be regarded as truthmakers. Objects seem right for existential truths but not others, so anti-monism seems best. | |
From: Adolph Rami (Introduction: Truth and Truth-Making [2009], 05) | |
A reaction: Presumably we need to identify the different types of truth (analytic, synthetic, general, particular...), and only then ask what truth-makers there are for the different types. To presuppose one type of truthmaker would be crazy. |
18341 | Truth-makers seem to be states of affairs (plus optional individuals), or individuals and properties [Rami] |
Full Idea: As truth-makers, some theorists only accept states of affairs, some only accept individuals and states of affairs, and some only accept individuals and particular properties. | |
From: Adolph Rami (Introduction: Truth and Truth-Making [2009], 06) | |
A reaction: It seems to me rash to opt for one of these. Truths come in wide-ranging and subtly different types, and the truth-makers probably have a similar range. Any one of these theories will almost certainly quickly succumb to a counterexample. |
18346 | 'Truth supervenes on being' only gives necessary (not sufficient) conditions for contingent truths [Rami] |
Full Idea: The thesis that 'truth supervenes on being' (with or without possible worlds) offers only a necessary condition for the truth of contingent propositions, whereas the standard truth-maker theory offers necessary and sufficient conditions. | |
From: Adolph Rami (Introduction: Truth and Truth-Making [2009], 09) | |
A reaction: The point, I suppose, is that the change in being might be irrelevant to the proposition in question, so any old change in being will not ensure a change in the truth of the proposition. Again we ask - but what is this truth about? |
18345 | 'Truth supervenes on being' avoids entities as truth-makers for negative truths [Rami] |
Full Idea: The important advantage of 'truth supervenes on being' is that it can be applied to positive and negative contingent truths, without postulating any entities that are responsible for the truth of negative truths. | |
From: Adolph Rami (Introduction: Truth and Truth-Making [2009], 09) | |
A reaction: [For this reason, Lewis favours a possible worlds version of the theory] I fear that it solves that problem by making the truth-maker theory so broad-brush that it not longer says very much, apart from committing it to naturalism. |
18343 | Maybe a truth-maker also works for the entailments of the given truth [Rami] |
Full Idea: The 'entailment principle' for truth-makers says that if x is a truth-maker for y, and y entails z, then x is a truth-maker for z. | |
From: Adolph Rami (Introduction: Truth and Truth-Making [2009], 08) | |
A reaction: I think the correct locution is that 'x is a potential truth-maker for z' (should anyone every formulate z, which in most cases they never will, since the entailments of y are probably infinite). Merricks would ask 'but are y and z about the same thing?'. |
18338 | Truth-making is usually internalist, but the correspondence theory is externalist [Rami] |
Full Idea: Most truth-maker theorists are internalists about the truth-maker relation. ...But the correspondence theory makes truth an external relation to some portion of reality. So a truth-maker internalist should not claim to be a narrow correspondence theorist. | |
From: Adolph Rami (Introduction: Truth and Truth-Making [2009], 05) | |
A reaction: [wording rearranged] Like many of Rami's distinctions in this article, this feels simplistic. Sharp distinctions can only be made using sharp vocabulary, and there isn't much of that around in philosophy! |
18337 | Correspondence theories assume that truth is a representation relation [Rami] |
Full Idea: One guiding intuition concerning a correspondence theory of truth says that the relation that accounts for the truth of a truth-bearer is some kind of representation relation. | |
From: Adolph Rami (Introduction: Truth and Truth-Making [2009], 05) | |
A reaction: I unfashionably cling on to some sort of correspondence theory. The paradigm case is of a non-linguistic animal which forms correct or incorrect views about its environment. Truth is a relation, not a property. I see the truth in a bad representation. |
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. |
18347 | Deflationist truth is an infinitely disjunctive property [Rami] |
Full Idea: According to the moderate deflationist truth is an infinitely disjunctive property. | |
From: Adolph Rami (Introduction: Truth and Truth-Making [2009], 10) | |
A reaction: [He cites Horwich 1998] That is, I presume, that truth is embodied in an infinity of propositions of the form '"p" is true iff p'. |
12005 | The symbol 'ι' forms definite descriptions; (ιx)F(x) says 'the x which is such that F(x)' [Forbes,G] |
Full Idea: We use the symbol 'ι' (Greek 'iota') to form definite descriptions, reading (ιx)F(x) as 'the x which is such that F(x)', or simply as 'the F'. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 4.1) | |
A reaction: Compare the lambda operator in modal logic, which picks out predicates from similar formulae. |
18350 | Truth-maker theorists should probably reject the converse Barcan formula [Rami] |
Full Idea: There are good reasons for the truth-maker theorist to reject the converse Barcan formula. | |
From: Adolph Rami (Introduction: Truth and Truth-Making [2009], note 16) | |
A reaction: In the text (p.15) Rami cites the inference from 'necessarily everything exists' to 'everything exists necessarily'. [See Williamson 1999] |
12010 | Is the meaning of 'and' given by its truth table, or by its introduction and elimination rules? [Forbes,G] |
Full Idea: The typical semantic account of validity for propositional connectives like 'and' presupposes that meaning is given by truth-tables. On the natural deduction view, the meaning of 'and' is given by its introduction and elimination rules. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 4.4) |
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'. |
12023 | Vagueness problems arise from applying sharp semantics to vague languages [Forbes,G] |
Full Idea: It is very plausible that the sorites paradoxes arose from the application of a semantic apparatus appropriate only for sharp predicates to languages containing vague predicates (rather than from deficiency of meaning, or from incoherence). | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 7.3) | |
A reaction: Sounds wrong. Of course, logic has been designed for sharp predicates, and natural languages are awash with vagueness. But the problems of vagueness bothered lawyers long before logicians like Russell began to worry about it. |
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). |
18336 | Internal relations depend either on the existence of the relata, or on their properties [Rami] |
Full Idea: An internal relation is 'existential' if x and y relate in that way whenever they both exist. An internal relation is 'qualitative' if x and y relate in that way whenever they have certain intrinsic properties. | |
From: Adolph Rami (Introduction: Truth and Truth-Making [2009], 05) | |
A reaction: [compressed - Rami likes to write these things in fashionable quasi-algebra, but I have a strong prejudice in this database for expressing ideas in English; call me old-fashioned] The distinction strikes me as simplistic. I would involve dispositions. |
12017 | In all instances of identity, there must be some facts to ensure the identity [Forbes,G] |
Full Idea: For each instance of identity or failure of identity, there must be facts in virtue of which that instance obtains. ..Enough has been said to lend this doctrine some plausibility. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 5.5) | |
A reaction: Penelope Mackie picks this out from Forbes as a key principle. It sounds to be in danger of circularity, unless the 'facts' can be cited without referring to, or implicitly making use of, identities - which seems unlikely. |
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. |
12024 | If we combined two clocks, it seems that two clocks may have become one clock. [Forbes,G] |
Full Idea: If we imagine a possible world in which two clocks in a room make one clock from half the parts of each, the judgement 'these two actual clocks could have been a single clock' does not seem wholly false. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 7.4) | |
A reaction: You would, of course, have sufficient parts left over to make a second clock, so they look like a destroyed clock, so I don't think I find Forbes's intuition on this one very persuasive. |
10938 | The extremes of essentialism are that all properties are essential, or only very trivial ones [Rami] |
Full Idea: It would be natural to label one extreme view 'maximal essentialism' - that all of an object's properties are essential - and the other extreme 'minimal' - that only trivial properties such as self-identity of being either F or not-F are essential. | |
From: Adolph Rami (Essential vs Accidental Properties [2008]) | |
A reaction: Personally I don't accept the trivial ones as being in any way describable as 'properties'. The maximal view destroys any useful notion of essence. Leibniz is a minority holder of the maximal view. I would defend a middle way. |
11885 | Only individual essences will ground identities across worlds in other properties [Forbes,G, by Mackie,P] |
Full Idea: Forbes argues that, unless we posit individual essences, we cannot guarantee that identities across possible worlds will be appropriately grounded in other properties. | |
From: report of Graeme Forbes (The Metaphysics of Modality [1985]) by Penelope Mackie - How Things Might Have Been 2.4 | |
A reaction: There is a confrontation between Wiggins, who says identity is primitive, and Forbes, who says identity must be grounded in other properties. I think I side with Forbes. |
12014 | An individual essence is a set of essential properties which only that object can have [Forbes,G] |
Full Idea: An individual essence of an object x is a set of properties I which satisfies the following conditions: i. every property P in I is an essential property of x; ii. it is not possible that some object y distinct from x has every member of I. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 5.1) | |
A reaction: I am coming to the view that stable natural kinds (like electrons or gold) do not have individual essences, but complex kinds (like tigers or tables) do. The view is based on the idea that explanatory power is what individuates an essence. |
12015 | Non-trivial individual essence is properties other than de dicto, or universal, or relational [Forbes,G] |
Full Idea: A non-trivial individual essence is properties other than a) those following from a de dicto truth, b) properties of existence and self-identity (or their cognates), c) properties derived from necessities in some other category. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 5.1) | |
A reaction: [I have compressed Forbes] Rather than adding all these qualificational clauses to our concept, we could just tighten up on the notion of a property, saying it is something which is causally efficacious, and hence explanatory. |
10940 | An 'individual essence' is possessed uniquely by a particular object [Rami] |
Full Idea: An 'individual essence' is a property that in addition to being essential is also unique to the object, in the sense that it is not possible that something distinct from that object possesses that property. | |
From: Adolph Rami (Essential vs Accidental Properties [2008], §5) | |
A reaction: She cites a 'haecceity' (or mere bare identity) as a trivial example of an individual essence. |
12013 | Essential properties depend on a category, and perhaps also on particular facts [Forbes,G] |
Full Idea: The essential properties of a thing will typically depend upon what category of thing it is, and perhaps also on some more particular facts about the thing itself. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 5.1) | |
A reaction: I see no way of dispensing with the second requirement, in the cases of complex entities like animals. If all samples are the same, then of course we can define a sample's essence through its kind, but not if samples differ in any way. |
10939 | 'Sortal essentialism' says being a particular kind is what is essential [Rami] |
Full Idea: According to 'sortal essentialism', an object could not have been of a radically different kind than it in fact is. | |
From: Adolph Rami (Essential vs Accidental Properties [2008], §4) | |
A reaction: This strikes me as thoroughly wrong. Things belong in kinds because of their properties. Could you remove all the contingent features of a tiger, leaving it as merely 'a tiger', despite being totally unrecognisable? |
13804 | A property is essential iff the object would not exist if it lacked that property [Forbes,G] |
Full Idea: A property P is an essential property of an object x iff x could not exist and lack P, that is, as they say, iff x has P at every world at which x exists. | |
From: Graeme Forbes (In Defense of Absolute Essentialism [1986], 1) | |
A reaction: This immediately places the existence of x outside the normal range of its properties, so presumably 'existence is not a predicate', but that dictum may be doubted. As it stands this definition will include trivial and vacuous properties. |
13805 | Properties are trivially essential if they are not grounded in a thing's specific nature [Forbes,G] |
Full Idea: Essential properties may be trivial or nontrivial. It is characteristic of P's being trivially essential to x that x's possession of P is not grounded in the specific nature of x. | |
From: Graeme Forbes (In Defense of Absolute Essentialism [1986], 2) | |
A reaction: This is where my objection to the modal view of essence arises. How is he going to explain 'grounded' and 'specific nature' without supplying an entirely different account of essence? |
12012 | Essential properties are those without which an object could not exist [Forbes,G] |
Full Idea: An essential property of an object x is a property without possessing which x could not exist. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 5.1) | |
A reaction: This is certainly open to question. See Joan Kung's account of Aristotle on essence. I am necessarily more than eight years old (now), and couldn't exist without that property, but is the property part of my essence? |
13808 | A relation is essential to two items if it holds in every world where they exist [Forbes,G] |
Full Idea: A relation R is essential to x and y (in that order) iff Rxy holds at every world where x and y both exist. | |
From: Graeme Forbes (In Defense of Absolute Essentialism [1986], 2) | |
A reaction: I find this bizarre. Not only does this seem to me to have nothing whatever to do with essence, but also the relation might hold even though it is a purely contingent matter. All rabbits are a reasonable distance from the local star. Essence of rabbit? |
10934 | Unlosable properties are not the same as essential properties [Rami] |
Full Idea: It is easy to confuse the notion of an essential property that a thing could not lack, with a property it could not lose. My having spent Christmas 2007 in Tennessee is a non-essential property I could not lose. | |
From: Adolph Rami (Essential vs Accidental Properties [2008], §1) | |
A reaction: The idea that having spent Christmas in Tennessee is a property I find quite bewildering. Is my not having spent my Christmas in Tennessee one of my properties? I suspect that real unlosable properties are essential ones. |
13806 | Trivially essential properties are existence, self-identity, and de dicto necessities [Forbes,G] |
Full Idea: The main groups of trivially essential properties are (a) existence, self-identity, or their consequences in S5; and (b) properties possessed in virtue of some de dicto necessary truth. | |
From: Graeme Forbes (In Defense of Absolute Essentialism [1986], 2) | |
A reaction: He adds 'extraneously essential' properties, which also strike me as being trivial, involving relations. 'Is such that 2+2=4' or 'is such that something exists' might be necessary, but they don't, I would say, have anything to do with essence. |
13807 | A property is 'extraneously essential' if it is had only because of the properties of other objects [Forbes,G] |
Full Idea: P is 'extraneously essential' to x iff it is possessed by x at any world w only in virtue of the possession at w of certain properties by other objects. | |
From: Graeme Forbes (In Defense of Absolute Essentialism [1986], 2) | |
A reaction: I would say that these are the sorts of properties which have nothing to do with being essential, even if they are deemed to be necessary. |
12022 | Same parts does not ensure same artefact, if those parts could constitute a different artefact [Forbes,G] |
Full Idea: Sameness of parts is not sufficient for identity of artefacts at a world, since the very same parts may turn up at different times as the parts of artefacts with different designs and functions. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 7.2) | |
A reaction: Thus the Ship of Theseus could be dismantled and turned into a barn (as happened with the 'Mayflower'). They could then be reconstituted as the ship, which would then have two beginnings (as Chris Hughes has pointed out). |
12025 | Artefacts have fuzzy essences [Forbes,G] |
Full Idea: Artefacts can be ascribed fuzzy essences. ...We might say that it is essential to an artefact to have 'most' of its parts. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 7.6) | |
A reaction: I think I prefer to accept the idea that essences are unstable things, in all cases. For all we know, electrons might subtly change their general character, or cease to be uniform, tomorrow. Essences explain, and what needs explaining changes. |
13809 | One might be essentialist about the original bronze from which a statue was made [Forbes,G] |
Full Idea: In the case of artefacts, there is an essentialism about original matter; for instance, it would be said of any particular bronze statue that it could not have been cast from a totally different quantity of bronze. | |
From: Graeme Forbes (In Defense of Absolute Essentialism [1986], 3) | |
A reaction: Forbes isn't endorsing this, and it doesn't sound convincing. He quotes the thought 'I wish I had made this pot from a different piece of clay'. We might corrupt a statue by switching bronze, but I don't think the sculptor could do so. |
12020 | An individual might change their sex in a world, but couldn't have differed in sex at origin [Forbes,G] |
Full Idea: In the time of a single world, the same individual can undergo a change of sex, but it is less clear that an individual of one sex could have been, from the outset, an individual of another. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 6.5) | |
A reaction: I don't find this support for essentiality of origin very persuasive. I struggle with these ideas. Given my sex yesterday, then presumably I couldn't have had a different sex yesterday. Given that pigs can fly, pigs can fly. What am I missing? |
11888 | Identities must hold because of other facts, which must be instrinsic [Forbes,G, by Mackie,P] |
Full Idea: Forbes has two principles of identity, which we can call the No Bare Identities Principle (identities hold in virtue of other facts), and the No Extrinsic Determination Principle (that only intrinsic facts of a thing establish identity). | |
From: report of Graeme Forbes (The Metaphysics of Modality [1985], 127-8) by Penelope Mackie - How Things Might Have Been 2.7 | |
A reaction: The job of the philosopher is to prise apart the real identities of things from the way in which we conceive of identities. I take these principles to apply to real identities, not conceptual identities. |
10933 | Physical possibility is part of metaphysical possibility which is part of logical possibility [Rami] |
Full Idea: The usual view is that 'physical possibilities' are a natural subset of the 'metaphysical possibilities', which in turn are a subset of the 'logical possibilities'. | |
From: Adolph Rami (Essential vs Accidental Properties [2008], §1) | |
A reaction: [She cites Fine 2002 for an opposing view] I prefer 'natural' to 'physical', leaving it open where the borders of the natural lie. I take 'metaphysical' possibility to be 'in all naturally possible worlds'. So is a round square a logical possibility? |
12003 | De re modal formulae, unlike de dicto, are sensitive to transworld identities [Forbes,G] |
Full Idea: The difference between de re and de dicto formulae is a difference between formulae which are, and formulae which are not, sensitive to the identities of objects at various worlds. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 3.1) |
10932 | If it is possible 'for all I know' then it is 'epistemically possible' [Rami] |
Full Idea: There is 'epistemic possibility' when it is 'for all I know'. That is, P is epistemically possible for agent A just in case P is consistent with what A knows. | |
From: Adolph Rami (Essential vs Accidental Properties [2008], §1) | |
A reaction: Two problems: maybe 'we' know, and A knows we know, but A doesn't know. And maybe someone knows, but we are not sure about that, which seems to introduce a modal element into the knowing. If someone knows it's impossible, it's impossible. |
12028 | De re necessity is a form of conceptual necessity, just as de dicto necessity is [Forbes,G] |
Full Idea: De re necessity does not differ from de dicto necessity in respect of how it arises: it is still a form of conceptual necessity. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 9.4) | |
A reaction: [Forbes proceeds to argue for this claim] Forbes defends a form of essentialism, but takes the necessity to arise from a posteriori truths because of the a priori involvement of other concepts (rather as Kripke argues). |
13810 | The source of de dicto necessity is not concepts, but the actual properties of the thing [Forbes,G] |
Full Idea: It is widely held that the source of de dicto necessity is in concepts, ..but I deny this... even with simple de dicto necessities, the source of the necessity is to be found in the properties to which the predicates of the de dicto truth refer. | |
From: Graeme Forbes (In Defense of Absolute Essentialism [1986], 3) | |
A reaction: It is normal nowadays to say this about de re necessities, but this is more unusual. |
12008 | Unlike places and times, we cannot separate possible worlds from what is true at them [Forbes,G] |
Full Idea: There is no means by which we might distinguish a possible world from what is true at it. ...Whereas our ability to separate a place, or a time, from its occupier is crucial to realism about places and times, as is a distance relation. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 4.2) | |
A reaction: He is objecting to Lewis's modal realism. I'm not fully convinced. It depends whether we are discussing real ontology or conceptual space. In the latter I see no difference between times and possible worlds. In ontology, a 'time' is weird. |
12009 | The problem with possible worlds realism is epistemological; we can't know properties of possible objects [Forbes,G] |
Full Idea: The main objection to realism about worlds is from epistemology. Knowledge of properties of objects requires experience of these objects, which must be within the range of our sensory faculties, but only concrete actual objects achieve that. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 4.2) | |
A reaction: This pinpoints my dislike of the whole possible worlds framework, ontologically speaking. I seem to be an actualist. I take possibilities to be inferences to the best explanation from the powers we know of in the actual world. We experience potentiality. |
12007 | Possible worlds are points of logical space, rather like other times than our own [Forbes,G] |
Full Idea: Someone impressed by the parallel between tense and modal operators ...might suggest that just as we can speak of places and times forming their own manifolds or spaces, so we can say that worlds are the points of logical space. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 4.2) | |
A reaction: I particularly like the notion of worlds being "points of logical space", and am inclined to remove it from this context and embrace it as the correct way to understand possible worlds. We must understand logical or conceptual space. |
12011 | Transworld identity concerns the limits of possibility for ordinary things [Forbes,G] |
Full Idea: An elucidation of transworld identity can be regarded as an elucidation of the boundaries of possibility for ordinary things. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 5.1) | |
A reaction: I presume that if we don't search for some such criterion, we just have to face the possibility that Aristotle could have been a poached egg in some possible world. To know the bounds of possibility, study the powers of actual objects. |
12016 | The problem of transworld identity can be solved by individual essences [Forbes,G] |
Full Idea: The motivation for investigating individual essences should be obvious, since if every object has such an essence, the problem of elucidating transworld identity can be solved. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 5.1) | |
A reaction: It is important that, if necessary, the identities be 'individual', and not just generic, by sortal, or natural kind. We want to reason about (and explain) truths at the fine-grained level of the individual, not just at the broad level of generalisation. |
12004 | Counterpart theory is not good at handling the logic of identity [Forbes,G] |
Full Idea: The outstanding technical objection to counterpart-theoretic semantics concerns its handling of the logic of identity. In quantified S5 (the orthodox semantics) a = b → □(a = b) is valid, but 'a' must not attach to two objects. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 3.5) |
12021 | Haecceitism attributes to each individual a primitive identity or thisness [Forbes,G] |
Full Idea: Haecceitism attributes to each individual a primitive identity or thisness, as opposed to the sort of essentialism that gives non-trivial conditions sufficient for transworld identity. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 6.6) | |
A reaction: 'Haecceitism' is the doctrine that things have primitive identity. A 'haecceity' is a postulated property which actually does the job. The key point of the view is that whatever it is is 'primitive', and not complex, or analysable. I don't believe it. |
12029 | We believe in thisnesses, because we reject bizarre possibilities as not being about that individual [Forbes,G] |
Full Idea: The natural response to an unreasonable hypothesis of possibility for an object x, that in such a state of affairs it would not be x which satisfies the conditions, is evidence that we do possess concepts of thisness for individuals. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 9.4) | |
A reaction: We may have a 'concept' of thisness, but we needn't be committed to the 'existence' of a thisness. There is a fairly universal intuition that cessation of existence of an entity when it starts to change can be a very vague matter. |
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. |
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. |
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. |
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. |
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? |
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'. |
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. |
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. |
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. |
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. |
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. |
