CHAPTER XV
PHILOSOPHYThe beginnings of Indian philosophy, which are to be found in the latest hymns of the Rigveda and in the Atharvaveda, are concerned with speculations on the origin of the world and on the eternal principle by which it is created and maintained. The Yajurveda further contains fantastic cosmogonic legends describing how the Creator produces all things by means of the omnipotent sacrifice. With these Vedic ideas are intimately connected, and indeed largely identical, those of the earlier Upanishads. This philosophy is essentially pantheistic and idealistic. By the side of it grew up an atheistic and empirical school of thought, which in the sixth century B.C. furnished the foundation of the two great unorthodox religious systems of Buddhism and Jainism.
The Upanishad philosophy is in a chaotic condition, but the speculations of this and of other schools of thought were gradually reduced to order and systematised in manuals from about the first century of our era onwards. Altogether nine systems may be distinguished, some of which must in their origin go back to the beginning of the sixth century B.C. at least. Of the six systems which are accounted orthodox no less than four were originally atheistic, and one remained so throughout. The strangeness of this fact disappears
