Abstract

In a well known paper, “Mind and Ideas in Berkeley” George Pitcher has argued that Berkeley's account of how minds are related to sensible ideas must be incoherent. Douglas Odegard has already criticized Pitcher's treatment of Berkeley, but the criticisms pertain to other questions. No one appears to have challenged Pitcher's most important argument. I hope to show that, while it is well worth analyzing, the argument fails to provide any effective reductio ad absurdum of Berkeley's real position.Pitcher's argument trades on two logically independent versions of the adverbial analysis of ideas. The first is what I shall call “the identity version”. Its proponent asserts that the ideas are identical with sensings, with mental acts or states of sensing which are adverbially describable. The philosopher who follows the second or “constitutive” version asserts that ideas are sensa and exist as constituents of sensing states. For him ideas are not mental states but are constituents of such states. A sponsor of either version will hold that sensings are qualities of the mind.
