18487 | We want to know what makes sentences true, rather than defining 'true' [McFetridge] |
Full Idea: The generalisation 'What makes a (any) sentence true?' is not a request for definitions of 'true' (the concept), but rather requests for (partial) explanations of why certain particular sentences are true. | |
From: Ian McFetridge (Truth, Correspondence, Explanation and Knowledge [1977], II) | |
A reaction: McFetridge is responding to the shortcomings of Tarski's account of truth. The mystery seems to be why some of our representations of the world are 'successful', and others are not. |
18488 | We normally explain natural events by citing further facts [McFetridge] |
Full Idea: If one were asked 'What makes salt soluble in water?', the most natural answer would be something of the style 'The fact that it has such-and-such structure'. | |
From: Ian McFetridge (Truth, Correspondence, Explanation and Knowledge [1977], II) | |
A reaction: Personally I would want to talk about its 'powers' (dispositional properties), rather than its 'structure' (categorical properties). This defends facts, but you could easily paraphrase 'fact' out of this reply (as McFetridge realised). |
23900 | Chance is compatible with necessity, and the two occur together [Weil] |
Full Idea: Chance is not the contrary of necessity; it is not incompatible with necessity. On the contrary, it never appears except at the same time as necessity. | |
From: Simone Weil (The Scientific Image [1941], p.175) | |
A reaction: She illustrates it with the six terminating results of a die throw, and the innumerabe ways the throw can occur. This thought strikes me as relevant to discussions of free will. …But I'm not sure I fully understand it. |
9591 | The human intellect has not been, and cannot be, fully formalized [Nagel/Newman] |
Full Idea: The resources of the human intellect have not been, and cannot be, fully formalized. | |
From: E Nagel / JR Newman (Gödel's Proof [1958], VIII) | |
A reaction: This conclusion derives from Gödel's Theorem. Some people (e.g. Penrose) get over-excited by this discovery, and conclude that the human mind is supernatural. Imagination is the key - it is a feature of rationality that escapes mechanization. |
23899 | The secret of art is that beauty is a just blend of unity and its opposite [Weil] |
Full Idea: A just blend of unity and that which opposes it is the condition of the beautiful, and it is the secret of art. | |
From: Simone Weil (The Scientific Image [1941], p.169) | |
A reaction: Rather sweeping, but the observation strikes me as fairly accurate. It seems to work for most novels, paintings and music, though more recent art may provide counterexamples. |
