12619 | We have no successful definitions, because they all use indefinable words [Fodor] |
Full Idea: There are practically no defensible examples of definitions; for all the examples we've got, practically all the words (/concepts) are undefinable. | |
From: Jerry A. Fodor (Concepts:where cogn.science went wrong [1998], Ch.3) | |
A reaction: I don't think a definition has to be defined all the way down. Aristotle is perfectly happy if you can get a concept you don't understand down to concepts you do. Understanding is the test, not further definitions. |
15063 | Some sentences depend for their truth on worldly circumstances, and others do not [Fine,K] |
Full Idea: There is a distinction between worldly and unworldly sentences, between sentences that depend for their truth upon the worldly circumstances and those that do not. | |
From: Kit Fine (Necessity and Non-Existence [2005], Intro) | |
A reaction: Fine is fishing around in the area between the necessary, the a priori, truthmakers, and truth-conditions. He appears to be attempting a singlehanded reconstruction of the concepts of metaphysics. Is he major, or very marginal? |
12620 | If 'exist' is ambiguous in 'chairs and numbers exist', that mirrors the difference between chairs and numbers [Fodor] |
Full Idea: People say 'exist' is ambiguous, because of the difference between 'chairs exist' and 'numbers exist'. A reply goes: the difference between the existence of chairs and the existence of numbers is strikingly like the difference between chairs and numbers. | |
From: Jerry A. Fodor (Concepts:where cogn.science went wrong [1998], Ch.3) | |
A reaction: To say 'numbers are objects which exist' is, to me, either a funny use of 'exist' or a funny use of 'object'. I think I will now vote for the latter. Just as 'real number' was a funny use of 'number', but we seem to have got used to it. |
15078 | There are levels of existence, as well as reality; objects exist at the lowest level in which they can function [Fine,K] |
Full Idea: Just as we recognise different levels of reality, so we should recognise different levels of existence. Each object will exist at the lowest level at which it can enjoy its characteristic form of life. | |
From: Kit Fine (Necessity and Non-Existence [2005], 10) | |
A reaction: I'm struggling with this claim, despite my sympathy for much of Fine's picture. I'm not sure that the so-called 'levels' of reality have different degrees of reality. |
15072 | Bottom level facts are subject to time and world, middle to world but not time, and top to neither [Fine,K] |
Full Idea: At the bottom are tensed or temporal facts, subject to the vicissitudes of time and hence of the world. Then come the timeless though worldly facts, subject to the world but not to time. Top are transcendental facts, subject to neither world nor time. | |
From: Kit Fine (Necessity and Non-Existence [2005], 08) | |
A reaction: For all of Fine's awesome grasp of logic and semantics, when he divides reality up as boldly as this I start to side a bit with the sceptics about modern metaphysics (like Ladyman and Ross). I daresay Fine acknowledges that it is 'speculative'. |
15071 | Tensed and tenseless sentences state two sorts of fact, which belong to two different 'realms' of reality [Fine,K] |
Full Idea: A tensed fact is stated by a tensed sentence while a tenseless fact is stated by a tenseless sentence, and they belong to two 'realms' of reality. That Socrates drank hemlock is in the temporal realm, while 2+2=4 is presumably in the timeless realm. | |
From: Kit Fine (Necessity and Non-Existence [2005], 07) | |
A reaction: Put so strongly, I suddenly find sales resistance to his proposal. All my instincts favour one realm, and I take 2+2=4 to be a highly general truth about that realm. It may be a truth of any possible realm, which would distinguish it. |
12613 | Empiricists use dispositions reductively, as 'possibility of sensation' or 'possibility of experimental result' [Fodor] |
Full Idea: Using dispositional analyses in aid of ontological reductions is what empiricism taught us. If you are down on cats, reduce them to permanent possibilities of sensation; if you are down on electrons, reduce them to possibilities of experimental outcome. | |
From: Jerry A. Fodor (Concepts:where cogn.science went wrong [1998], Ch.1) | |
A reaction: The cats line is phenomenalism; the electrons line is instrumentalism. I like this as a serious warning about dispositions, even where they seem most plausible, as in the disposition of glass to break when struck. Why is it thus disposed? |
15075 | Modal features are not part of entities, because they are accounted for by the entity [Fine,K] |
Full Idea: It is natural to suggest that to be a man is to have certain kind of temporal-modal profile. ...but it seems natural that being a man accounts for the profile, ...so one should not appeal to an object's modal features in stating what the object is. | |
From: Kit Fine (Necessity and Non-Existence [2005], 09) | |
A reaction: This strikes me as a correct and very helpful point, as I am tempted to think that the modal dispositions of a thing are intrinsic to its identity. If we accept 'powers', must they be modal in character? Fine backs a sortal approach. That's ideology. |
15065 | What it is is fixed prior to existence or the object's worldly features [Fine,K] |
Full Idea: The identity of an object - what it is - is not a worldly matter; essence will precede existence in that the identity of an object may be fixed by its unworldly features even before any question of its existence or other worldly features is considered. | |
From: Kit Fine (Necessity and Non-Existence [2005], Intro) | |
A reaction: I'm not clear how this cashes out. If I remove the 'worldly features' of an object, what is there left which establishes identity? Fine carefully avoids talk of 'a priori' knowledge of identity. |
15076 | Essential features of an object have no relation to how things actually are [Fine,K] |
Full Idea: It is the core essential features of the object that will be independent of how things turn out, and they will be independent in the sense of holding regardless of circumstances, not whatever the circumstances. | |
From: Kit Fine (Necessity and Non-Existence [2005], 09) | |
A reaction: The distinction at the end seems to be that 'regardless' pays no attention to circumstances, whereas 'whatever' pays attention to all circumstances. In other words, essence has no relationship to how things are. Plausible. Nice to see 'core'. |
15073 | Self-identity should have two components, its existence, and its neutral identity with itself [Fine,K] |
Full Idea: The existential identity of an object with itself needs analysis into two components, one the neutral identity of the object with itself, and the other its existence. The existence of the object appears to be merely a gratuitous addition to its identity. | |
From: Kit Fine (Necessity and Non-Existence [2005], 08) | |
A reaction: This is at least a step towards clarification of the notion, which might be seen as just a way of asserting that something 'has an identity'. Fine likes the modern Fregean way of expressing this, as an equality relation. |
15074 | We would understand identity between objects, even if their existence was impossible [Fine,K] |
Full Idea: If there were impossible objects, ones that do not possibly exist, we would have no difficulty in understanding what it is for such objects to be identical or distinct than in the case of possible objects. | |
From: Kit Fine (Necessity and Non-Existence [2005], 08) | |
A reaction: Thus, a 'circular square' seems to be the same as a 'square circle'. Fine is arguing for identity to be independent of any questions of existence. |
15064 | Proper necessary truths hold whatever the circumstances; transcendent truths regardless of circumstances [Fine,K] |
Full Idea: We distinguish between the necessary truths proper, those that hold whatever the circumstances, and the transcendent truths, those that hold regardless of the circumstances. | |
From: Kit Fine (Necessity and Non-Existence [2005], Intro) | |
A reaction: Fine's project seems to be dividing the necessities which derive from essence from the necessities which tended to be branded in essentialist discussions as 'trivial'. |
15070 | It is the nature of Socrates to be a man, so necessarily he is a man [Fine,K] |
Full Idea: It is of the nature of Socrates to be a man; and from this it appears to follow that necessarily he is a man. | |
From: Kit Fine (Necessity and Non-Existence [2005], 04) | |
A reaction: I'm always puzzled by this line of thought, because it is only the intrinsic nature of beings like Socrates which decides in the first place what a 'man' is. How can something help to create a category, and then necessarily belong to that category? |
15069 | Possible worlds may be more limited, to how things might actually turn out [Fine,K] |
Full Idea: An alternative conception of a possible world says it is constituted, not by the totality of facts, or of how things might be, but by the totality of circumstances, or how things might turn out. | |
From: Kit Fine (Necessity and Non-Existence [2005], 02) | |
A reaction: The general idea is to make a possible world more limited than in Idea 15068. It only contains properties arising from 'engagement with the world', and won't include timeless sentences. It is a bunch of possibilities, not of actualities? |
15068 | The actual world is a totality of facts, so we also think of possible worlds as totalities [Fine,K] |
Full Idea: We are accustomed think of the actual world as the totality of facts, and so we think of any possible world as being like the actual world in settling the truth-value of every single proposition. | |
From: Kit Fine (Necessity and Non-Existence [2005], 02) | |
A reaction: Hence it is normal to refer to a possible world as a 'maximal' set of of propositions (sentences, etc). See Idea 15069 for his proposed alternative view. |
12617 | Associationism can't explain how truth is preserved [Fodor] |
Full Idea: The essential problem is to explain how thinking manages reliably to preserve truth; and Associationism, as Kant rightly pointed out to Hume, hasn't the resources to do so. | |
From: Jerry A. Fodor (Concepts:where cogn.science went wrong [1998], Ch.1) | |
A reaction: One might be able to give an associationist account of truth-preservation if one became a bit more externalist about it, so that the normal association patterns track their connections with the external world. |
3158 | Theories of intentionality presuppose rationality, so can't explain it [Dennett] |
Full Idea: Intentional theory is vacuous as psychology because it presupposes and does not explain rationality or intelligence. | |
From: Daniel C. Dennett (Brainstorms:Essays on Mind and Psychology [1978], p.15?) | |
A reaction: Virtually every philosophical theory seems to founder because it presupposes something like the thing it is meant to explain. I agree that 'intentionality' is a slightly airy concept that would probably reduce to something better. |
3159 | Beliefs and desires aren't real; they are prediction techniques [Dennett] |
Full Idea: Intentional systems don't really have beliefs and desires, but one can explain and predict their behaviour by ascribing beliefs and desires to them. This strategy is pragmatic, not right or wrong. | |
From: Daniel C. Dennett (Brainstorms:Essays on Mind and Psychology [1978], p.7?) | |
A reaction: If the ascription of beliefs and desires explains behaviour, then that is good grounds for thinking they might be real features of the brain, and even if that is not so, they are real enough as abstractions from brain events, like the 'economic climate'. |
12615 | Mental representations are the old 'Ideas', but without images [Fodor] |
Full Idea: The idea that there are mental representations is the idea that there are Ideas minus the idea that Ideas are images. | |
From: Jerry A. Fodor (Concepts:where cogn.science went wrong [1998], Ch.1) | |
A reaction: Good for you, Fodor. I've always thought that the vociferous contempt with which modern philosphers refer to the old notion of 'Ideas' was grossly exaggerated. At last someone puts a clear finger on what seems to be the difficulty. |
6650 | Fodor is now less keen on the innateness of concepts [Fodor, by Lowe] |
Full Idea: Fodor has recently changed his mind about the innateness of concepts, which he formerly championed. | |
From: report of Jerry A. Fodor (Concepts:where cogn.science went wrong [1998]) by E.J. Lowe - Introduction to the Philosophy of Mind Ch.7 n25 | |
A reaction: There is some sensible middle road to be charted here. We presumably do not have an innate idea of a screwdriver, but there are plenty of basic concepts in logic and perception that are plausibly thought of as innate. |
12618 | It is essential to the concept CAT that it be satisfied by cats [Fodor] |
Full Idea: Nothing in any mental life could be the concept CAT unless it is satisfied by cats. If you haven't got a concept that applies to cats, that entails that you haven't got the CAT concept. | |
From: Jerry A. Fodor (Concepts:where cogn.science went wrong [1998], Ch.2) | |
A reaction: Of course, having a concept that applies to cats doesn't entail that you have the CAT concept. Quine's 'gavagai', for example. I think Fodor is right in this idea. |
12614 | I prefer psychological atomism - that concepts are independent of epistemic capacities [Fodor] |
Full Idea: I argue for a very strong version of psychological atomism; one according to which what concepts you have is conceptually and metaphysically independent of what epistemic capacities you have. | |
From: Jerry A. Fodor (Concepts:where cogn.science went wrong [1998], Ch.1) | |
A reaction: This is a frontal assault on the tradition of Frege, Dummett and Peacocke. I immediately find Fodor's approach more congenial, because he wants to say what a concept IS, rather than just place it within some larger scheme of things. |
12621 | Definable concepts have constituents, which are necessary, individuate them, and demonstrate possession [Fodor] |
Full Idea: The definition theory says that concepts are complex structures which entail their constituents. By saying this, it guarantees both the connection between content and necessity, and the connection between concept individuation and concept possession. | |
From: Jerry A. Fodor (Concepts:where cogn.science went wrong [1998], Ch.5) | |
A reaction: He cites Pinker as a spokesman for the definitional view. This is the view Fodor attacks, in favour of his atomistic account. He adds in a note that his view also offered to reduce conceptual truth to logical truth. |
12622 | Many concepts lack prototypes, and complex prototypes aren't built from simple ones [Fodor] |
Full Idea: Many concepts have no prototypes; and there are many complex concepts whose prototypes aren't related to the prototypes of their constituents in the way compositional explanation of productivity and systematicity requires. | |
From: Jerry A. Fodor (Concepts:where cogn.science went wrong [1998], Ch.5) | |
A reaction: His favourite example of the latter is 'pet fish', where the prototype of 'pet' is hardly ever a fish, and the prototype of 'fish' is usually much bigger than goldfish. Fodor is arguing that concepts are atomic. |
12623 | The theory theory can't actually tell us what concepts are [Fodor] |
Full Idea: If the theory theory has a distinctive and coherent answer to the 'What's a concept?' question on offer, it's a well-kept secret. | |
From: Jerry A. Fodor (Concepts:where cogn.science went wrong [1998], Ch.5) | |
A reaction: Not an argument, but worth recording as an attitude. I certainly agree that accounts which offer some sort of answer to 'What is a concept?' have an immediate head's start on those which don't. |
12616 | English has no semantic theory, just associations between sentences and thoughts [Fodor] |
Full Idea: English has no semantics. Learning English isn't learning a theory about what its sentences mean, it's learning how to associate its sentences with the corresponding thoughts. | |
From: Jerry A. Fodor (Concepts:where cogn.science went wrong [1998], Ch.1) | |
A reaction: This sounds remarkably close to John Locke's account of language (which I always thought was seriously underrated). Presumably we can then say that the 'thought' (or Locke's 'idea') is the meaning, which is old-fashioned real meanings. |
15077 | It is said that in the A-theory, all existents and objects must be tensed, as well as the sentences [Fine,K] |
Full Idea: It is said that there is no room in the A-theorists' ontology for a realm of timeless existents. Just as there is a tendency to think that every sentence is tensed, so there is a tendency to think that every object must enjoy a tensed form of existence. | |
From: Kit Fine (Necessity and Non-Existence [2005], 10) | |
A reaction: Fine is arguing for certain things to exist or be true independently of time (such as arithmetic, or essential identities). I struggle with the notion of timeless existence. |
15067 | A-theorists tend to reject the tensed/tenseless distinction [Fine,K] |
Full Idea: Most A-theorists have been inclined to reject the tensed/tenseless distinction. | |
From: Kit Fine (Necessity and Non-Existence [2005], 01) | |
A reaction: Presumably this is because they reject the notion of 'tenseless' truths. But sentences like 'two and two make four' seem not to be very tensy. |
15066 | B-theorists say tensed sentences have an unfilled argument-place for a time [Fine,K] |
Full Idea: B-theorists regard tensed sentences as incomplete expressions, implicitly containing an unfilled argument-place for the time at which they are to be evaluated. | |
From: Kit Fine (Necessity and Non-Existence [2005], 01) | |
A reaction: To distinguish past from future it looks as if you would need two argument-places, not one. Then there are 'used to be' and 'had been' to evaluate. |
