6396 | A sentence is held true because of a combination of meaning and belief [Davidson] |
Full Idea: A sentence is held true because of two factors: what the holder takes the sentence to mean, and what he believes. | |
From: Donald Davidson (Thought and Talk [1975], p.20) | |
A reaction: A key question is whether a belief (e.g. an imagistic one, or one held by an animal) could be true, even though no sentence is involved. Linguistic philosophers tend to avoid this question, or assume the answer is 'no'. |
11145 | Having a belief involves the possibility of being mistaken [Davidson] |
Full Idea: Someone cannot have a belief unless he understands the possibility of being mistaken. | |
From: Donald Davidson (Thought and Talk [1975], p.170) | |
A reaction: If you pretend to throw a ball for a dog, but don't release it, the dog experiences being mistaken very dramatically. |
6397 | The concept of belief can only derive from relationship to a speech community [Davidson] |
Full Idea: We have the idea of belief from its role in the interpretation of language; as a private attitude it is not intelligible except in relation to public language. So a creature must be a member of a speech community to have the concept of belief. | |
From: Donald Davidson (Thought and Talk [1975], p.22) | |
A reaction: This shows how Wittgenstein's Private Language Argument (e.g. Idea 4152) hovers behind Davidson's philosophy. The idea is quite persuasive. A solitary creature just follows its mental states. The question of whether it believes them is a meta-thought. |
9807 | In pursuing truth, anything less certain than mathematics is a waste of time [Descartes] |
Full Idea: In our search for the direct road towards truth we should busy ourselves with no object about which we cannot attain a certitude equal to that of the demonstrations of Arithmetic and Geometry. | |
From: René Descartes (Rules for the Direction of the Mind [1628], Rule II), quoted by Alain Badiou - Mathematics and Philosophy: grand and little p.8 | |
A reaction: A beautiful statement of the way in which rationalist philosophy was founded on the model of mathematics (esp. Euclid), with all its concomitant problems. The most important concept of the last hundred years may well be fallibilist rationalism. |
12893 | Contextualism says sceptical arguments are true, relative to their strict context [Cohen,S] |
Full Idea: Contextualism explains the appeal of sceptical arguments by allowing that the claims of the sceptic are true, relative to the very strict context in which they are made. | |
From: Stewart Cohen (Contextualism Defended [2005], p.57) | |
A reaction: This strikes me a right. I've always thought that global scepticism must be conceded if we are being very strict indeed about justification, but also that it is ridiculous to be that strict. So the epistemological question is 'How strict should we be?' |
12896 | Knowledge is context-sensitive, because justification is [Cohen,S] |
Full Idea: The context-sensitivity of knowledge is inherited from one of its components, i.e. justification. | |
From: Stewart Cohen (Contextualism Defended [2005], p.68) | |
A reaction: I think this is exactly right - that there is nothing relative or contextual about what is actually true, or what someone believes, but knowleddge is wholly relative because it rests on shifting standards of justification. |
12894 | There aren't invariant high standards for knowledge, because even those can be raised [Cohen,S] |
Full Idea: The problem for invariantism is that competent speakers, under sceptical pressure, tend to deny that we know even the most conspicuous facts of perception, the clearest memories etc. | |
From: Stewart Cohen (Contextualism Defended [2005], p.58) | |
A reaction: This is aimed at Idea 12892. This seems to me a strong response to the rather weak invariantist case (that there is 'really and truly' only one invariant standard for knowledge). Full strength scepticism about everything demolishes all knowledge. |
6392 | Thought depends on speech [Davidson] |
Full Idea: The thesis I want to refine and then argue for is that thought depends on speech. | |
From: Donald Davidson (Thought and Talk [1975], p.8) | |
A reaction: This has the instant and rather implausible implication that animals don't think. He is not, of course, saying that all thought is speech, which would leave out thinking in images. You can't do much proper thought without concepts and propositions. |
6393 | A creature doesn't think unless it interprets another's speech [Davidson] |
Full Idea: A creature cannot have a thought unless it is an interpreter of the speech of another. | |
From: Donald Davidson (Thought and Talk [1975], p.9) | |
A reaction: His use of the word 'creature' shows that he is perfectly aware of the issue of whether animals think, and he is, presumably, denying it. At first glance this sounds silly, but maybe animals don't really 'think', in our sense of the word. |
11144 | Concepts are only possible in a language community [Davidson] |
Full Idea: A private attitude is not intelligible except as an adjustment to the public norms provided by language. It follows that a creature must be a member of speech community if it is to have the concept of belief. | |
From: Donald Davidson (Thought and Talk [1975], p.170) | |
A reaction: This obviously draws on Wittgenstein's private language argument, and strikes me as blatantly wrong, because I take higher animals to have concepts without language. Pure vision gives rise to concepts. I don't even think they are necessarily conscious. |
6395 | An understood sentence can be used for almost anything; it isn't language if it has only one use [Davidson] |
Full Idea: Once a sentence is understood, an utterance of it may be used to serve almost any extra-linguistic purpose; an instrument that could be put to only one use would lack autonomy of meaning, which means it should not be counted as language. | |
From: Donald Davidson (Thought and Talk [1975], p.17) | |
A reaction: I find this point very appealing, in opposition to the Wittgenstein view of meaning as use. Passwords seem to me a striking case of the separation of meaning and use. I like the phrase 'autonomy of meaning'. Random sticks can form a word. |
6394 | The pattern of sentences held true gives sentences their meaning [Davidson] |
Full Idea: Although most utterances are not concerned with truth, it is the pattern of sentences held true that gives sentences their meaning. | |
From: Donald Davidson (Thought and Talk [1975], p.14) | |
A reaction: Davidson's distinctive version of meaning holism, as opposed to Quine's rather behaviouristic version. I agree that we relate to people through the pattern of sentences they hold true, but I am unconvinced that this 'gives sentences their meaning'. |
