8188 | Davidson takes truth to attach to individual sentences [Davidson, by Dummett] |
Full Idea: Davidson, by contrast to Frege, has taken truth as attaching to linguistic items, that is, to actual or hypothetical token sentences. | |
From: report of Donald Davidson (True to the Facts [1969]) by Michael Dummett - Truth and the Past 1 | |
A reaction: My personal notion of truth is potentially applicable to animals, so this doesn't appeal to me. I am happy to think of animals as believing simple propositions that never get as far as language, and being right or wrong about them. |
3597 | Foundations need not precede other beliefs [Wittgenstein] |
Full Idea: I do not explicitly learn the propositions that stand fast for me. I can discover them subsequently like the axis around which a body rotates. | |
From: Ludwig Wittgenstein (On Certainty [1951], §152), quoted by Michael Williams - Problems of Knowledge Ch.14 | |
A reaction: A nice metaphor for the way in which axioms are derived. It is also close to Quine's metaphor of the 'net' of understanding, with the centre area 'standing fast'. Not neat and tidy, though. |
3596 | Total doubt can't even get started [Wittgenstein, by Williams,M] |
Full Idea: Wittgenstein remarked that if you tried to doubt everything, you would not get as far as doubting anything. | |
From: report of Ludwig Wittgenstein (On Certainty [1951]) by Michael Williams - Problems of Knowledge Ch.14 |
4721 | If you are not certain of any fact, you cannot be certain of the meaning of your words either [Wittgenstein] |
Full Idea: If you are not certain of any fact, you cannot be certain of the meaning of your words either. | |
From: Ludwig Wittgenstein (On Certainty [1951], §114) | |
A reaction: A wonderfully challenging aphorism. I suspect that it is true, but not really a problem. We all know the meaning of 'Loch Ness Monster', as long as we don't get too fussy. And for local objects I am happy that I know the facts. |
7825 | The politics of Leibniz was the reunification of Christianity [Stewart,M] |
Full Idea: The politics of Leibniz may be summed up in one word: theocracy. The specific agenda motivating much of his work was to reunite the Protestant and Catholic churches | |
From: Matthew Stewart (The Courtier and the Heretic [2007], Ch. 5) | |
A reaction: This would be a typical project for a rationalist philosopher, who thinks that good reasoning will gradually converge on the one truth. |
