Abstract
In this thoughtful, rich, and extremely ambitious book, Norton Nelkin develops a "Scientific Cartesian" theory of sensation and perception, consciousness, conceptual content, and concept formation. The theory is Cartesian primarily because its account of mental states is realist, individualist, and internalist; Nelkin also holds, with Descartes, that perceptions are spontaneous judgments and that at least some of our concepts are innate. But, unlike Descartes, Nelkin rejects dualism and treats the mind as something that can be studied by the same methods as other natural phenomena; indeed, Nelkin goes further than many contemporary theorists in attempting to make his views consistent with, and informed by, studies in the cognitive sciences.
