10792 | The substitutional quantifier is not in competition with the standard interpretation [Kripke, by Marcus (Barcan)] |
Full Idea: Kripke proposes that the substitutional quantifier is not a replacement for, or in competition with, the standard interpretation. | |
From: report of Saul A. Kripke (A Problem about Substitutional Quantification? [1976]) by Ruth Barcan Marcus - Nominalism and Substitutional Quantifiers p.165 |
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. |
6624 | Dennett denies the existence of qualia [Dennett, by Lowe] |
Full Idea: Dennett goes to the extreme of denying the existence of qualia altogether. | |
From: report of Daniel C. Dennett (Quining Qualia [1988]) by E.J. Lowe - Introduction to the Philosophy of Mind Ch.3 | |
A reaction: I sympathise with Dennett. Once you know how physically complex and rapid a quale is (about nine billion connections, all firing continuously), the notion that it seems to be some new 'thing', while just being a process, seems fine. Like a waterfall. |
