Many of the problems of philosophy are of such broad relevance to human concerns, and so complex in their ramifications, that they are in one form or another perennially present. In the course of time, they yield to philosophical study and may be reexamined by each age in the light of its broader scientific knowledge and deepened ethical and religious experience. Thus, one who approaches the study of philosophy in the hope of understanding the best of what it affords will look for both fundamental interpretations and contemporary achievements. Written by a group of distinguished philosophers, the Foundations of Philosophy Series aims to exhibit some of the main problems in the various fields of philosophy as they stand at the present stage of philosophical inquiry.
