15130 | If a property is possible, there is something which can have it [Williamson] |
Full Idea: Barcan's axiom says if there can be something that has a certain property, then there is something that can have that property. It and its converse are not obviously correct or incorrect. They claim that it is non-contingent what individuals there are. | |
From: Timothy Williamson (Laudatio: Prof Ruth Barcan Marcus [2011], p.1) | |
A reaction: Williamson defends the two Barcan formulas, but the more I understand them the less plausible they sound to me. |
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. |
21227 | The Cogito demands a bridge to the world, and ends in isolating the ego [Velarde-Mayol] |
Full Idea: All philosophies inspired in the Cogito have the problem of building a bridge from the starting point of consciousness to the external world. The result of this is the isolation and solitude of the very ego. | |
From: Victor Velarde-Mayol (On Husserl [2000], 4.7.2) | |
A reaction: This strikes me as a pretty good reason not to develop a philosophy which is inspired by the Cogito. |
21215 | The representation may not be a likeness [Velarde-Mayol] |
Full Idea: Representationalism is the doctrine that maintains that the object is represented in consciousness by means of an image. ...One should not confuse an image with a likeness. | |
From: Victor Velarde-Mayol (On Husserl [2000], 2.4.3) | |
A reaction: Helpful reminder that sense-data or whatever may not be a likeness. But then how do they represent? Symbolic representation needs massive interpretation. |
21219 | Find the essence by varying an object, to see what remains invariable [Velarde-Mayol] |
Full Idea: Eidetic Reduction consists of producing variations in the individual object until we see what is invariable in it. What is invariable is its essence or Eidos. | |
From: Victor Velarde-Mayol (On Husserl [2000], 3.2.2) | |
A reaction: This strikes me as an excellent idea. It more or less describes the method of science. Chemical atoms were thought to be unsplittable, until someone tried a new variation for dealing with them. |
