ABSTRACT
The point of Berkeley's major criticism of Locke pertains to his view of primary qualities and the substratum in which they supposedly inhere. I shall begin with what he said about primary qualities. His remarks on these qualities were based partly on his conception of a secondary quality, and I shall have to refer to the latter in the course of my discussion. To make things easier for myself, I shall use the term "secondary quality" as Berkeley did - to refer to the mind-dependent qualities produced by the powers that Locke called secondary qualities. The difference in their terminology here will not be confusing if it is carefully noted. Evidently, Berkeley did not regard secondary qualities as Lockean powers because he did not believe that such things existed. In his view all genuine qualities are mind-dependent.
