13750 | Analysis aims at the structure of facts, which are needed to give a rationale to analysis [Urmson, by Schaffer,J] |
Full Idea: Urmson explains the direction of analysis as 'towards a structure...more nearly similar to the structure of the fact', adding that this metaphysical picture is needed as a 'rationale of the practice of analysis'. | |
From: report of J.O. Urmson (Philosophical Analysis [1956], p.24-5) by Jonathan Schaffer - On What Grounds What n30 | |
A reaction: In other words, only realists can be truly motivated to keep going with analysis. Merely analysing language-games is doable, but hardly exciting. |
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. |
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. |
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? |
19553 | Commitment to 'I have a hand' only makes sense in a context where it has been doubted [Hawthorne] |
Full Idea: If I utter 'I know I have a hand' then I can only be reckoned a cooperative conversant by my interlocutors on the assumption that there was a real question as to whether I have a hand. | |
From: John Hawthorne (The Case for Closure [2005], 2) | |
A reaction: This seems to point to the contextualist approach to global scepticism, which concerns whether we are setting the bar high or low for 'knowledge'. |
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. |
19551 | How can we know the heavyweight implications of normal knowledge? Must we distort 'knowledge'? [Hawthorne] |
Full Idea: Those who deny skepticism but accept closure will have to explain how we know the various 'heavyweight' skeptical hypotheses to be false. Do we then twist the concept of knowledge to fit the twin desiderata of closue and anti-skepticism? | |
From: John Hawthorne (The Case for Closure [2005], Intro) | |
A reaction: [He is giving Dretske's view; Dretske says we do twist knowledge] Thus if I remember yesterday, that has the heavyweight implication that the past is real. Hawthorne nicely summarises why closure produces a philosophical problem. |
19552 | We wouldn't know the logical implications of our knowledge if small risks added up to big risks [Hawthorne] |
Full Idea: Maybe one cannot know the logical consequences of the proposition that one knows, on account of the fact that small risks add up to big risks. | |
From: John Hawthorne (The Case for Closure [2005], 1) | |
A reaction: The idea of closure is that the new knowledge has the certainty of logic, and each step is accepted. An array of receding propositions can lose reliability, but that shouldn't apply to logic implications. Assuming monotonic logic, of course. |
19554 | Denying closure is denying we know P when we know P and Q, which is absurd in simple cases [Hawthorne] |
Full Idea: How could we know that P and Q but not be in a position to know that P (as deniers of closure must say)? If my glass is full of wine, we know 'g is full of wine, and not full of non-wine'. How can we deny that we know it is not full of non-wine? | |
From: John Hawthorne (The Case for Closure [2005], 2) | |
A reaction: Hawthorne merely raises this doubt. Dretske is concerned with heavyweight implications, but how do you accept lightweight implications like this one, and then suddenly reject them when they become too heavy? [see p.49] |
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. |
