This book provides a detailed and critical account of Schopenhauer's central philosophical achievement; his account of the self and its relation to the world of objects. The author's historical approach is designed to show the philosophical interest of the theme, and explores in unusual depth Schopenhauer's often ambivalent relation to Kant. It also highlights his view of self and world in Wittgenstein and Nietzsche, and traces the many points of contact between Schopenhauer's thought and current philosophical debates about the self.
