14712 | A sentence is a priori if no possible way the world might actually be could make it false [Chalmers] |
Full Idea: The Core Thesis for rationalist 2D semantics is that for any sentence S, S is apriori iff S has a necessary 1-intension. (That is, there is no possible way the world might be that, if it actually obtained, would make S false). | |
From: David J.Chalmers (Epistemic Two-Dimensional Semantics [2004], p.165), quoted by Laura Schroeter - Two-Dimensional Semantics 2.3.2 | |
A reaction: [The parenthesis is by Schroeter] A '1-intension' is defined by a diagonal on a 2D semantic matrix. Chalmers defends conceivability as the guide to possibility. This is a very traditional view of the a priori, expressed in modern terms. |
2397 | 'Perception' means either an action or a mental state [Chalmers] |
Full Idea: 'Perception' can be used to refer either to the act of perceiving, or the internal state that arises as a result. | |
From: David J.Chalmers (The Conscious Mind [1996], 1.2.2) |
2422 | The structure of the retina has already simplified the colour information which hits it [Chalmers] |
Full Idea: In vision three varieties of cones abstract out information according to the amount of light present in various overlapping wavelength ranges. Immediately, many distinctions present in the original light wave are lost. | |
From: David J.Chalmers (The Conscious Mind [1996], 3.8.3) |
