| 22140 | The greatest philosophers are methodical; it is what makes them great [Grice] |
| Full Idea: The greatest philosophers have been the greatest, and most self-conscious, methodologists; indeed, I am tempted to regard the fact as primarily accounting for their greatness as philosophers. | |
| From: H. Paul Grice (Reply to Richards [1986], p.66), quoted by Stephen Boulter - Why Medieval Philosophy Matters 3 | |
| A reaction: I agree. Philosophy is nothing if it is not devoted to the attempt to be fully rational, and that implies consistency and coherence. If a thinker doesn't even try to be systematic, I would not consider them to be a philosopher. |
| 5035 | The two basics of reasoning are contradiction and sufficient reason [Leibniz] |
| Full Idea: The two first principles of reasoning are: the principle of contradiction, and the principle of the need for giving a reason. | |
| From: Gottfried Leibniz (A Specimen of Discoveries [1686], p.75) | |
| A reaction: Could animals have any reasoning ability (say, in solving a physical problem)? Leibniz's criteria both require language. Note the overlapping of the principle of sufficient reason (there IS a reason) with the contractual idea of GIVING reasons. |
| 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? |
| 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. |
| 5038 | Assume that mind and body follow their own laws, but God has harmonised them [Leibniz] |
| Full Idea: Why not assume that God initially created the soul and body with so much ingenuity that, whilst each follows its own laws and properties and operations, all thing agree most beautifull among themselves? This is the 'hypothesis of concomitance'. | |
| From: Gottfried Leibniz (A Specimen of Discoveries [1686], p.80) | |
| A reaction: They may be in beautifully planned harmony, but how do we know that they are in harmony? Presumably their actions must be compared, and God would even have to harmonise the comparison. Parallelism seems to imply epiphenomenalism or idealism. |
| 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. |
| 5037 | God doesn't decide that Adam will sin, but that sinful Adam's existence is to be preferred [Leibniz] |
| Full Idea: God does not decide whether Adam should sin, but whether that series of things in which there is an Adam whose perfect individual notion involves sin should nevertheless be preferred to others. | |
| From: Gottfried Leibniz (A Specimen of Discoveries [1686], p.78) | |
| A reaction: Compare whether the person responsible for setting a road speed limit is responsible for subsequent accidents. Leibniz's belief that the world could have been made no better than it is (by an omnipotent being) strikes me as blind faith, not an argument. |
