Philosophy can be intriguing--and at times baffling. It deals with the central problems of the human condition--with important questions of free will, morality, life after death, the limits of logic and reason--though often in rather esoteric terms. Now, in The Oxford Companion to Philosophy, readers have the most authoritative and engaging one-volume reference work on philosophy available, offering clear and reliable guidance to the ideas of all notable philosophers from antiquity to the present day, and to the major philosophical systems around the globe, from Confucianism to phenomenology.
