(b) It decreases by a factor of two. (c) It increases by a factor of four. (d) It decreases by a factor of four. (e) Nothing happens to it.
Phil 7 Lecture 1 What are the minimal conditions for being a mind 1. Beliefs and pain are mental 2. R. Rorty thinks there is no category distinction before descrates 3.
