Abstract

My purpose herein is to demonstrate that Berkeley's only use of the argument from perceptual relativity (APR), in both of his major works, is ad hominem, that he uses it to undermine what he calls materialism. Specifically, I show that Berkeley does not use APR to conclude that sensible qualities are mind-dependent; rather he uses APR only to conclude that they are not in material substances; and that his real argument for the former is a quite different one: the heat-pain identification argument
