doubt true that more definite chronological information would be a very desirable thing, yet I am of opinion that the little chronological data we have give us a fair amount of help in forming a general notion about the growth and development of the different systems by mutual association and conflict. If the condition of the development of philosophy in India had been the same as in Europe, definite chronological knowledge would be considered much more indispensable. For, when one system supersedes another, it is indispensably necessary that we should know which preceded and which succeeded. But when the systems are developing side by side, and when we are getting them in their richer and better forms, the interest with regard to the conditions, nature and environment of their early origin has rather a historical than a philosophical interest. I have tried as best I could to form certain general notions as regards the earlier stages of some of the systems, but though the various features of these systems at these stages in detail may not be ascertainable, yet this, I think, could never be considered as invalidating the whole programme. Moreover, even if we knew definitely the correct dates of the thinkers of the same system we could not treat them separately, as is done in European philosophy, without unnecessarily repeating the same thing twenty times over; for they all dealt with the same system, and tried to bring out the same type of thought in more and more determinate forms. The earliest literature of India is the Vedas. These consist mostly of hymns in praise of nature gods, such as fire, wind, etc. Excepting in some of the hymns of the later parts of the work (probably about 1000 B.C.), there is not much philosophy in them in our sense of the term. It is here that we first find intensely interesting philosophical questions of a more or less cosmological character expressed in terms of poetry and imagination. In the later Vedic works called the Brâhmaf@nas and the Âra@nyakas written mostly in prose, which followed the Vedic hymns, there are two tendencies, viz. one that sought to establish the magical forms of ritualistic worship, and the other which indulged in speculative thinking through crude generalizations. This latter tendency was indeed much feebler than the former, and it might appear that the ritualistic tendency had actually swallowed up what little of philosophy the later parts of the Vedic hymns were trying to express, but there are unmistakable marks that this tendency 7
