With the exception of the one case to be mentioned immediately, we are forced to take the same position in regard to the similarity between other forms of early Greek and Hindu philosophy. Both Thales and Parmenides were indeed anticipated by Hindu sages, and the Eleatic school seems to be but a reflexion of the Upanishads. The doctrines of Anaximander and Heraclitus are, perhaps, not known first in Greece, but there is no evidence that they were not original to Greece, or that they were borrowed from India, however much older may be the parallel trains of thought on Indic soil.
Quite as decidedly, however, as we deny all appearance of borrowing on the part of the founders of other early Grecian schools, must we claim the thought of India to be the archetype of Pythagorean philosophy. After a careful review of the points of contact, and weighing as dispassionately as possible the historical evidence for and against the originality of Pythagoras, we are unable to come to any other conclusion than that the Greek philosopher took his whole system indirectly from India. His ‘numbers,’ indeed, are the S[=a]nkhya only in appearances.[28] But his theory of metempsychosis is the Indic sams[=a]ra, and Plato is full of Sankhyan thought, worked out by him but taken from Pythagoras. Before the sixth century B.C. all the religious-philosophical ideas of Pythagoras are current in India (L. von Schroeder, Pythagoras). If there were but one or two of these cases, they might be set aside as accidental coincidences, but such coincidences are too numerous to be the result of chance. Even in details the transmigration theory of Pythagoras harmonizes with that of India. Further (after Schroeder und Garbe) may be mentioned the curious prohibition against eating beans; the Hesiodic-Pythagorean [Greek: pros elion me omichein]; the vow of silence, like that taken by the Hindu muni; the doctrine of five elements (aether as fifth); above all, the so-called Pythagorean Theorem, developed in the mathematical Culvas[=u]tras[29] of India; the irrrational number [square root symbol]2; then the whole character of
