3695 | Philosophy is a priori if it is anything [Bonjour] |
Full Idea: My conviction is that philosophy is a priori if it is anything. | |
From: Laurence Bonjour (In Defence of Pure Reason [1998], Pref) | |
A reaction: How about knowledge of a posteriori necessities, such as the length of a metre, known by observation of the standard metre in Paris? |
3651 | Perceiving necessary connections is the essence of reasoning [Bonjour] |
Full Idea: If one never in fact grasps any necessary connections between anything, it is hard to see what reasoning could possible amount to. | |
From: Laurence Bonjour (In Defence of Pure Reason [1998], §4.3) |
3700 | Coherence can't be validated by appeal to coherence [Bonjour] |
Full Idea: The epistemic authority of coherence cannot itself be established by appeal to coherence. | |
From: Laurence Bonjour (In Defence of Pure Reason [1998], §3.7 n50) | |
A reaction: The standard approach amongs modern philosophers (following, I think, Kripke) is to insist on 'intuition' as basic, despite all its problems. I have no better suggestion. |
2463 | A standard naturalist view is realist, externalist, and computationalist, and believes in rationality [Fodor] |
Full Idea: There seems to be an emerging naturalist consensus that is Realist in ontology and epistemology, externalist in semantics, and computationalist in cognitive psychology, which nicely allows us to retain our understanding of ourselves as rational creatures. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §4) |
2435 | Psychology has to include the idea that mental processes are typically truth-preserving [Fodor] |
Full Idea: A psychology that can't make sense of such facts as that mental processes are typically truth-preserving is ipso facto dead in the water. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §1.3) |
2442 | Inferences are surely part of the causal structure of the world [Fodor] |
Full Idea: Inferences are surely part of the causal structure of the world. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §3) |
3697 | The concept of possibility is prior to that of necessity [Bonjour] |
Full Idea: While necessity and possibility are interdefinable concepts, it is the idea of a possible world or situation which is intuitively primary. | |
From: Laurence Bonjour (In Defence of Pure Reason [1998], §1.3) |
3704 | Moderate rationalists believe in fallible a priori justification [Bonjour] |
Full Idea: Moderate rationalism preserves a priori justification, but rejects the idea that it is infallible. | |
From: Laurence Bonjour (In Defence of Pure Reason [1998], §4.1) |
3707 | Our rules of thought can only be judged by pure rational insight [Bonjour] |
Full Idea: Criteria or rules do not somehow apply to themselves. They must be judged by the sort of rational insight or intuition that the rationalist is advocating. | |
From: Laurence Bonjour (In Defence of Pure Reason [1998], §5.2) |
3696 | A priori justification requires understanding but no experience [Bonjour] |
Full Idea: A proposition will count as being justified a priori as long as no appeal to experience is needed for the proposition to be justified - once it is understood. | |
From: Laurence Bonjour (In Defence of Pure Reason [1998], §1.2) | |
A reaction: Could you 'understand' that a square cannot be circular without appeal to experience? I'm losing faith in the pure a priori. |
3703 | You can't explain away a priori justification as analyticity, and you can't totally give it up [Bonjour] |
Full Idea: Moderate empiricists try unsuccessfully to explain a priori justification by means of analyticity, and radical empiricist attempts to dispense with a priori justification end in nearly total scepticism. | |
From: Laurence Bonjour (In Defence of Pure Reason [1998], §4.1) | |
A reaction: My working theory is neither of the above. Because we can abstract from the physical world, we can directly see/experience generalised (and even necessary) truths about it. |
3706 | A priori justification can vary in degree [Bonjour] |
Full Idea: A priori justification can vary in degree. | |
From: Laurence Bonjour (In Defence of Pure Reason [1998], §4.5) | |
A reaction: This idea, which I trace back at least to Russell, seems to me one of breakthrough ideas in modern thought. It means that a priori knowledge can be reconnected with a posteriori knowledge. |
3699 | The induction problem blocks any attempted proof of physical statements [Bonjour] |
Full Idea: The attempt to prove physical statements on the basis of sensory evidence is defeated by the problem of induction. | |
From: Laurence Bonjour (In Defence of Pure Reason [1998], §3.6) | |
A reaction: This sounds like a logician's use of the word 'prove', which would be a pretty forlorn hope. Insofar as experience proves anything, fully sensing a chair proves its existence. |
3701 | Externalist theories of justification don't require believers to have reasons for their beliefs [Bonjour] |
Full Idea: An externalist theory of epistemic justification or warrant need not involve the possession by the believer of anything like a reason for thinking that their belief is true. | |
From: Laurence Bonjour (In Defence of Pure Reason [1998], §3.7) | |
A reaction: That is the problem with externalism. If the believer does not have a reason, then why would they believe? Externalists are interesting on justification, but daft about belief. Why do I believe I know something, when I can't recall how I learnt it? |
2462 | Control of belief is possible if you know truth conditions and what causes beliefs [Fodor] |
Full Idea: Premeditated cognitive management is possible if knowing the contents of one's thoughts would tell you what would make them true and what would cause you to have them. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §4) | |
A reaction: I love the idea of 'cognitive management'. Since belief is fairly involuntary, I subject myself to the newspapers, books, TV and conversation which will create the style of beliefs to which I aspire. Why? |
3702 | Externalism means we have no reason to believe, which is strong scepticism [Bonjour] |
Full Idea: If externalism is the final story, we have no reason to think that any of our beliefs are true, which amounts to a very strong and intuitively implausible version of scepticism. | |
From: Laurence Bonjour (In Defence of Pure Reason [1998], §3.7) | |
A reaction: A very good point. I may, like a cat, know many things, with good external support, but as soon as I ask sceptical questions, I sink without trace if I lack internal reasons. |
2454 | We can deliberately cause ourselves to have true thoughts - hence the value of experiments [Fodor] |
Full Idea: A creature that knows what makes its thoughts true and what would cause it to have them, could therefore cause itself to have true thoughts. …This would explain why experimentation is so close to the heart of our cognitive style. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §4) |
2455 | Interrogation and experiment submit us to having beliefs caused [Fodor] |
Full Idea: You can put yourself into a situation where you may be caused to believe that P. Putting a question to someone who is in the know is one species of this behaviour, and putting a question to Nature (an experiment) is another. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §4) |
2460 | Participation in an experiment requires agreement about what the outcome will mean [Fodor] |
Full Idea: To be in the audience for an experiment you have to believe what the experimenter believes about what the outcome would mean, but not necessarily what the outcome will be. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §4) |
2461 | An experiment is a deliberate version of what informal thinking does all the time [Fodor] |
Full Idea: Experimentation is an occasional and more or less self-conscious exercise in what informal thinking does all the time without thinking about it. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §4) |
2458 | Theories are links in the causal chain between the environment and our beliefs [Fodor] |
Full Idea: Theories function as links in the causal chains that run from environmental outcomes to the beliefs that they cause the inquirer to have. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §4) |
3709 | Induction must go beyond the evidence, in order to explain why the evidence occurred [Bonjour] |
Full Idea: Inductive explanations must be conceived of as something stronger than mere Humean constant conjunction; …anything less than this will not explain why the inductive evidence occurred in the first place. | |
From: Laurence Bonjour (In Defence of Pure Reason [1998], §7.7) |
2443 | I say psychology is intentional, semantics is informational, and thinking is computation [Fodor] |
Full Idea: I hold that psychological laws are intentional, that semantics is purely informational, and that thinking is computation (and that it is possible to hold all of these assumptions at once). | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §4) | |
A reaction: When he puts it baldly like that, it doesn't sound terribly persuasive. Thinking is 'computation'? Raw experience is irrelevant? What is it 'like' to spot an interesting connection between two propositions or concepts? It's not like adding 7 and 5. |
2453 | We are probably the only creatures that can think about our own thoughts [Fodor] |
Full Idea: I think it is likely that we are the only creatures that can think about the contents of our thoughts. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §4) | |
A reaction: I think this is a major idea. If you ask me the traditional question - what is the essential difference between us and other animals? - this is my answer (not language, or reason). We are the metathinkers. |
2445 | Semantics v syntax is the interaction problem all over again [Fodor] |
Full Idea: The question how mental representations could be both semantic, like propositions, and causal, like rocks, trees, and neural firings, is arguably just the interaction problem all over again. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §4) | |
A reaction: Interesting way of presenting the problem. If you seem to be confronting the interaction problem, you have probably drifted into a bogus dualist way of thinking. Retreat, and reformulate you questions and conceptual apparatus, till the question vanishes. |
2446 | Cartesians consider interaction to be a miracle [Fodor] |
Full Idea: The Cartesian view is that the interaction problem does arise, but is unsolvable because interaction is miraculous. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §4) | |
A reaction: A rather unsympathetic statement of the position. Cartesians might think that God could explain to us how interaction works. Cartesians are not mysterians, I think, but they see no sign of any theory of interaction. |
2464 | Type physicalism equates mental kinds with physical kinds [Fodor] |
Full Idea: Type physicalism is, roughly, the doctrine that psychological kinds are identical to neurological kinds. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], App A n.1) | |
A reaction: This gets my general support, leaving open the nature of 'kinds'. Presumably the identity is strict, as in 'Hesperus is identical to Phosphorus'. It seems unlikely that if you and I think the 'same' thought, that we have strictly identical brain states. |
2447 | Hume has no theory of the co-ordination of the mind [Fodor] |
Full Idea: What Hume didn't see was that the causal and representational properties of mental symbols have somehow to be coordinated if the coherence of mental life is to be accounted for. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §4) | |
A reaction: Certainly the idea that it all somehow becomes magic at the point where the brain represents the world is incoherent - but it is a bit magical. How can the whole of my garden be in my brain? Weird. |
2440 | Propositional attitudes are propositions presented in a certain way [Fodor] |
Full Idea: Propositional attitudes are really three-place relations, between a creature, a proposition, and a mode of presentation (which are sentences of Mentalese). | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §2.II) | |
A reaction: I'm not sure about 'really'! Why do we need a creature? Isn't 'hoping it will rain' a propositional attitude which some creature may or may not have? Fodor wants it to be physical, but it's abstract? |
2450 | Rationality has mental properties - autonomy, productivity, experiment [Fodor] |
Full Idea: Mentalism isn't gratuitous; you need it to explain rationality. Mental causation buys you behaviours that are unlike reflexes in at least three ways: they're autonomous, they're productive, and they're experimental. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §4) | |
A reaction: He makes his three ways sound all-or-nothing, which is (I believe) the single biggest danger when thinking about the mind. "Either you are conscious, or you are not..." |
3708 | All thought represents either properties or indexicals [Bonjour] |
Full Idea: I assume that the contents of thought can be accounted for by appeal to just two general sorts of ingredient - properties (including relations) and indexicals. | |
From: Laurence Bonjour (In Defence of Pure Reason [1998], §6.7) | |
A reaction: I don't accept that relations are a type of properties. Since he does not include objects or substances, I take it that he considers objects to be bundles of properties. |
2437 | XYZ (Twin Earth 'water') is an impossibility [Fodor] |
Full Idea: There isn't any XYZ, and there couldn't be any, and so we don't have to worry about it. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §2.I) | |
A reaction: Jadeite and Nephrite are real enough, which are virtually indistinguishable variants of jade. You just need Twin Jewellers instead of Twin Earths. We could build them, and employ twins to work there. |
2441 | Truth conditions require a broad concept of content [Fodor] |
Full Idea: We need the idea of broad content to make sense of the fact that thoughts have the truth-conditions that they do. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §2.II) | |
A reaction: There seems to be (as Dummett points out) a potential circularity here, as you can hardly know the truth-conditions of something if you don't already know its content. |
3114 | Concepts aren't linked to stuff; they are what is caused by stuff [Fodor] |
Full Idea: If the words of 'Swamp Man' (spontaneously created, with concepts) are about XYZ on Twin Earth, it is not because he's causally connected to the stuff, but because XYZ would cause his 'water' tokens (in the absence of H2O). | |
From: Jerry A. Fodor (The Elm and the Expert [1993], App B) | |
A reaction: The sight of the Eiffel tower causes my 'France' tokens, so is my word "France" about the Eiffel Tower? What would cause my 'nothing' tokens? |
2452 | Knowing the cause of a thought is almost knowing its content [Fodor] |
Full Idea: If you know the content of a thought, you know quite a lot about what would cause you to have it. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §4) | |
A reaction: I'm not sure where this fits into the great jigsaw of the mind, but it strikes me as an acute and important observation. The truth of a thought is not essential to make you have it. Ask Othello. |
2432 | Is content basically information, fixed externally? [Fodor] |
Full Idea: I assume intentional content reduces (in some way) to information. …The content of a thought depends on its external relations; on the way that the thought is related to the world, not the way that it is related to other thoughts. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §1.2) | |
A reaction: Does this make Fodor a 'weak' functionalist? The 'strong' version would say a thought is merely a location in a flow diagram, but Fodor's 'mentalism' includes a further 'content' in each diagram box. |
2438 | In the information view, concepts are potentials for making distinctions [Fodor] |
Full Idea: Semantics, according to the informational view, is mostly about counterfactuals; what counts for the identity of my concepts is not what I do distinguish but what I could distinguish if I cared to (even using instruments and experts). | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §2.I) | |
A reaction: We all differ in our discriminations (and awareness of expertise), so our concepts would differ, which is bad news for communication (see Idea 223). The view has some plausibility, though. |
2439 | Semantic externalism says the concept 'elm' needs no further beliefs or inferences [Fodor] |
Full Idea: It is the essence of semantic externalism that there is nothing that you have to believe, there are no inferences that you have to accept, to have the concept 'elm'. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §2.I) | |
A reaction: [REMINDER: broad content is filed in 18.C.7, under 'Thought' rather than under language. That is because I am a philospher of thought, rather than of language. |
2457 | If meaning is information, that establishes the causal link between the state of the world and our beliefs [Fodor] |
Full Idea: It is the causal connection between the state of the world and the contents of beliefs that the reduction of meaning to information is designed to insure. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §4) | |
A reaction: I'm not clear why characterising the contents of a belief in terms of its information has to amount to a 'reduction'. A cup of tea isn't reduced to tea. Connections imply duality. |
2451 | To know the content of a thought is to know what would make it true [Fodor] |
Full Idea: If you know the content of a thought, you thereby know what would make the thought true. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §4) | |
A reaction: The truthmaker might by physically impossible, and careful thought might show it to be contradictory - but that wouldn't destroy the meaning. |
2433 | For holists no two thoughts are ever quite the same, which destroys faith in meaning [Fodor] |
Full Idea: If what you are thinking depends on all of what you believe, then nobody ever thinks the same thing twice. …That is why so many semantic holists (Quine, Putnam, Rorty, Churchland, probably Wittgenstein) end up being semantic eliminativists. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §1.2b) | |
A reaction: If linguistic holism is nonsense, this is easily settled. What I say about breakfast is not changed by reading some Gibbon yesterday. |
1757 | The Electra: she knows this man, but not that he is her brother [Eucleides, by Diog. Laertius] |
Full Idea: The 'Electra': Electra knows that Orestes is her brother, but not that this man is Orestes, so she knows and does not know her brother simultaneously. | |
From: report of Eucleides (fragments/reports [c.410 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 02.Eu.4 | |
A reaction: Hence we distinguish 'know of', 'know that' and 'know how'. Hence Russell makes 'knowledge by acquaintance' fundamental, and descriptions come later. |
2436 | It is claimed that reference doesn't fix sense (Jocasta), and sense doesn't fix reference (Twin Earth) [Fodor] |
Full Idea: The standard view is that Frege cases [knowing Jocasta but not mother] show that reference doesn't determine sense, and Twin cases [knowing water but not H2O] show that sense doesn't determine reference. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §1.3) | |
A reaction: How about 'references don't contain much information', and 'descriptions may not fix what they are referring to'? Simple really. |
2434 | Broad semantics holds that the basic semantic properties are truth and denotation [Fodor] |
Full Idea: Broad semantic theories generally hold that the basic semantic properties of thoughts are truth and denotation. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §1.2b) | |
A reaction: I think truth and denotation are the basic semantic properties, but I am dubious about whole-hearted broad semantic theories, so I seem to have gone horribly wrong somewhere. |
2459 | Externalist semantics are necessary to connect the contents of beliefs with how the world is [Fodor] |
Full Idea: You need an externalist semantics to explain why the contents of beliefs should have anything to do with how the world is. | |
From: Jerry A. Fodor (The Elm and the Expert [1993], §4) | |
A reaction: Since externalist semantics only emerged in the 1970s, that implies that no previous theory had any notion that language had some connection to how the world is. Eh? |
3698 | Indeterminacy of translation is actually indeterminacy of meaning and belief [Bonjour] |
Full Idea: The thesis of the indeterminacy of translation would be better described as the thesis of the indeterminacy of meaning and belief. | |
From: Laurence Bonjour (In Defence of Pure Reason [1998], §3.5) | |
A reaction: Not necessarily. It is not incoherent to believe that the target people have a coherent and stable system of meaning and belief, but finding its translation indeterminate because it is holistic, and rooted in a way of life. |
3028 | The chief good is unity, sometimes seen as prudence, or God, or intellect [Eucleides] |
Full Idea: The chief good is unity, which is known by several names, for at one time people call it prudence, at another time God, at another intellect, and so on. | |
From: Eucleides (fragments/reports [c.410 BCE]), quoted by Diogenes Laertius - Lives of Eminent Philosophers 02.9.2 | |
A reaction: So the chief good is what unites and focuses our moral actions. Kant calls that 'the will'. |
