7331 | A theory of meaning comes down to translating sentences into Fregean symbolic logic [Davidson, by Macey] |
Full Idea: For a theory of meaning for a fragment of natural language, what Davidson requires, in effect, is that the sentences be translatable into the language of Frege's symbolic logic. | |
From: report of Donald Davidson (In Defence of Convention T [1973]) by David Macey - Penguin Dictionary of Critical Theory | |
A reaction: This assumes the adequacy of Fregean logic, which seems unlikely. Is this the culmination of Leibniz's dream of a fully logical language - so that anything that won't fit into our logical form is ruled (logical positivist style) as meaningless? |
4398 | An event causes another just if the second event would not have happened without the first [Lewis, by Psillos] |
Full Idea: Lewis gives an account of causation in terms of counterfactual conditionals (roughly, an event c causes an event e iff if c had not happened then e would not have happened either). | |
From: report of David Lewis (works [1973]) by Stathis Psillos - Causation and Explanation Intro | |
A reaction: This feels wrong to me. It is a version of Humean constant conjunction, but counterfactuals are too much a feature of our minds, and not sufficiently a feature of the world, to do this job. Tricky. |
16689 | The schools said spirits lack extension, and wonder how many could dance on a needle's point [More,H] |
Full Idea: Many, not without reason, laugh at those ridiculous fancies of the schools, that rashly take away all extensions from spirits, whether souls or angels, and then dispute how many of them booted and spurred may dance on a needle's point at once. | |
From: Henry More (Immortality of the Soul [1659], III.2.1), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 17.3 | |
A reaction: This famous idea originated with William Chillingworth. More's version is the classic one. Pasnau cites Aquinas Summa 1a 52.3 as discussing the actual question (and says this couldn't happen). |
