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'. |
6900 | A prior understanding of beauty is needed to assert that the Form of the Beautiful is beautiful [Westaway] |
Full Idea: If it were asserted that the Form of the Beautiful was itself beautiful, such a statement would require a prior understanding of the concept of beauty, so would immediately lead to an infinite regress, so the Forms can't be self-predicating. | |
From: Luke Westaway (talk [2005]), quoted by PG - Db (ideas) | |
A reaction: This is a nice clear statement of the mess that Plato gets himself into if he wants the Forms to be self-predicating. Clearly the Form of the Beautiful can't be beautiful, but must be that which gives other things their beauty. |
6956 | At what point does an object become 'whole'? [Westaway] |
Full Idea: At what point does an object become 'whole'? | |
From: Luke Westaway (talk [2005]), quoted by PG - Db (ideas) | |
A reaction: This nice question strikes me as the central one in mereology. It is tempting to reply that the matter is entirely conventional, but there seems an obvious fact about something missing if one piece is absent from a jigsaw, or a cube is chipped. |
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. |
7335 | The Chinese Room should be able to ask itself questions in Mandarin [Westaway] |
Full Idea: If the Chinese Room is functionally equivalent to a Mandarin speaker, it ought to be able to ask itself questions in Mandarin (and it can't). | |
From: Luke Westaway (talk [2005]), quoted by PG - Db (ideas) | |
A reaction: Searle might triumphantly say that this proves there is no understanding in the room, but the objection won't go away, because the room is presumably functionally equivalent to a speaker, and not just a mere translator (who might use mechanical tricks). |
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'. |
1748 | Archelaus was the first person to say that the universe is boundless [Archelaus, by Diog. Laertius] |
Full Idea: Archelaus was the first person to say that the universe is boundless. | |
From: report of Archelaus (fragments/reports [c.450 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 02.Ar.3 |
5989 | Archelaus said life began in a primeval slime [Archelaus, by Schofield] |
Full Idea: Archelaus wrote that life on Earth began in a primeval slime. | |
From: report of Archelaus (fragments/reports [c.450 BCE]) by Malcolm Schofield - Archelaus | |
A reaction: This sounds like a fairly clearcut assertion of the production of life by evolution. Darwin's contribution was to propose the mechanism for achieving it. We should honour the name of Archelaus for this idea. |
