Samkhya is one of India's oldest philosophical systems, and this volume of the Encyclopedia of Indian Philosophies, coedited by Gernald James Larson and Ram Shankar Bhattacharya, and under the general editorship of Karl H. Potter, traces the history of the system from its beginnings in the third or fourth century B.C.E. up through the twentieth century. The volume includes a lengthy Introduction (written by G.J. Larsen) which discusses the history of the system and its philosophical contours overall.
