Since the cognitive revolution of the 1960s, there has been a resurgence of interest in the study of the philosophical assumptions and implications of psychology. Several significant themes, such as the foundations of knowledge, behaviorism, rationality, emotion, and cognitive science span both philosophy and psychology, and are covered here along with a wide range of issues in the fields of folk psychology, clinical psychology, neurophysiology, and professional ethics. The Philosophy of Psychology will be essential reading for students and academics in theoretical issues in psychology, philosophy of psychology, cognitive science, philosophy of mind and related courses.
