| 10245 | One geometry cannot be more true than another [Poincaré] |
| Full Idea: One geometry cannot be more true than another; it can only be more convenient. | |
| From: Henri Poincaré (Science and Method [1908], p.65), quoted by Stewart Shapiro - Philosophy of Mathematics | |
| A reaction: This is the culminating view after new geometries were developed by tinkering with Euclid's parallels postulate. |
| 8478 | Dewey argued long before Wittgenstein that there could not seriously be a private language [Dewey, by Orenstein] |
| Full Idea: Dewey argued in the twenties that there could not be, in any serious sense, a private language. Wittgenstein also, years later, came to appreciate this point. | |
| From: report of John Dewey (works [1926]) by Alex Orenstein - W.V. Quine Ch.6 | |
| A reaction: A nice historical footnote to perhaps the most famous argument in twentieth century philosophy. Can anyone send me the Dewey reference? |
| 2685 | The Greek 'philia' covers all good and fruitful relationships [Cooper,JM] |
| Full Idea: The Greek 'philia' is much wider than our "friendship"; it includes family relationships, and business relationships and membership of institutions. | |
| From: John M. Cooper (Aristotle on Friendship [1977], p.301) |
