We may consider first of all the Sâṅkhya.[740] Tradition ascribes its invention to Kapila, but he is a mere name unconnected with any date or other circumstance. It is probable that the principal ideas of the Sâṅkhya germinated several centuries before our era but we have no evidence whatever as to when they were first formulated in Sûtras. The name was current as the designation of a philosophical system fairly early[741] but the accepted text-books are all late. The most respected is the Sâṅkhya-pravacana,[742] attributed to Kapila but generally assigned by European critics to the fourteenth century A.D. Considerably more ancient, but still clearly a metrical epitome of a system already existing, is the Sâṅkhya-Kârikâ, a poem of seventy verses which was translated into Chinese about 560 A.D. and may be a few centuries older. Max Müller regarded the Tattva-samâsa, a short tract consisting chiefly of an enumeration of topics, as the most ancient Sâṅkhya formulary, but the opinion of scholars as to its age is not unanimous. The name Sâṅkhya is best interpreted as signifying enumeration in allusion to the predilection of the school for numbered lists, a predilection equally noticeable in early Buddhism. The object of the system set forth in these works is strictly practical. In the first words of the Sâṅkhya-pravacana, the complete cessation of suffering is the end of man, and the Sâṅkhya is devised to enable him to attain it. Another formula divides the contents of the Sâṅkhya into four topics--(_a_) that from which man must liberate himself, or suffering, (_b_) liberation, or the cessation of suffering, (_c_) the cause of suffering, or the failure to discriminate between the soul and matter, (_d_) the means of liberation, or discriminating knowledge. This division obviously resembles the four Truths of Buddhism. The object proposed is the same and the method analogous, though not identical, for Buddhism speaks as a religion and lays greater stress on conduct. The theory of the Sâṅkhya, briefly stated, is this. There exist, uncreated and from all eternity, on the one side matter and on the other individual souls. The world, as we know it, is due entirely to the evolution of matter. Suffering is the result of souls being in bondage to matter, but this bondage does not affect the nature of the soul and in one sense is not real, for when souls acquire discriminating knowledge and see that they are not matter, then the bondage ceases and they attain to eternal peace.
