Only in the West does science exist at a stage of development which we recognize to-day as valid. Empirical knowledge, reflection on problems of the cosmos and of life, philosophical and theological wisdom of the most profound sort, are not confined to it, though in the case of the last the full development of a systematic theology must be credited to Christianity under the influence of Hellenism, since there were only fragments in Islam and in a few Indian sects.

The Indian natural sciences, though well developed in observation, lacked the method of experiment, which was, apart from beginnings in antiquity, essentially a product of the Renaissance, as was the modern laboratory. Hence medicine, especially in India, though highly developed
