This accessible and lively introduction considers the main problems and debates in contemporary philosophy of mind. The central theme of the book is that intentionality, or the mind's direction upon its objects - sometimes described as the mind's power to represent or be 'about' things - isthe essential feature of all mental phenomena. Crane engages in a subsidiary theme, the mind-body problem, asking to what extent a physicalist reductive account of mental phenomena is possible, or even necessary. Proposing an original and unified theory of all the phenomena of mind, Crane opposesthose currently popular conceptions of the mind which divide mental phenomena into two very different kinds, the intentional and the qualitative. In the light of his theory, Crane gives an account of the main problems of the philosophy of mind: the mind-body problem, the problem of intentionality(or mental representation), the problem of consciousness, and the problem of perception. He also attempts to give solutions to these problems. This book provides an fresh and engaging exploration of those questions at the centre of the philosophy of mind in an accessible and lucid style which will appeal to all students, including those new to the subject.
