Book excerpt: Consciousness emerges as the key topic in this second edition of Owen Flanagan's popular introduction to cognitive science and the philosophy of psychology. in a new chapter Flanagan develops a neurophilosophical theory of subjective mental life. He brings recent developments in the theory of neuronal group selection and connectionism to bear on the problems of the evolution of consciousness, qualia, the unique first-personal aspects of consciousness, the causal role of consciousness, and the function and development of the sense of personal identity. He has also substantially revised the chapter on cognitive psychology and artificial intelligence to incorporate recent discussions of connectionism and parallel distributed processing.
