THREE:When the power and value of these primitive speculations can no longer be denied, their originality is sometimes questioned by the systematic detractors of everything Hellenic. Thales and the rest, we are told, simply borrowed their theories without acknowledgment from a storehouse of Oriental wisdom on which the Greeks are supposed to have drawn as freely as Coleridge drew on German philosophy. Sometimes each system is affiliated to one of the great Asiatic religions; sometimes they are all traced back to the schools of Hindostan. It is natural that no two critics should agree, when the rival explanations are based on nothing stronger than superficial analogies and accidental coincidences. Dr. Zeller in his wonderfully learned, clear, and sagacious work on Greek philosophy, has carefully sifted some of the hypotheses referred to, and shown how destitute they are of internal or external evidence, and how utterly they fail to account for the facts. The oldest and best authorities, Plato and Aristotle, knew nothing about such a derivation of Greek thought from Eastern sources. Isocrates does, indeed, mention that Pythagoras borrowed his philosophy7 from Egypt, but Isocrates did not even pretend to be a truthful narrator. No Greek of the early period except those regularly domiciled in Susa seems to have been acquainted with any language but his own. Few travelled very far into Asia, and of those few, only one or two were philosophers. Democritus, who visited more foreign countries than any man of his time, speaks only of having discussed mathematical problems with the wise men whom he encountered; and even in mathematics he was at least their equal.9 It was precisely at the greatest distance from Asia, in Italy and Sicily, that the systems arose which seem to have most analogy with Asiatic modes of thought. Can we suppose that the traders of those times were in any way qualified to transport the speculations of Confucius and the Vedas to such a distance from their native homes? With far better reason might one expect a German merchant to carry a knowledge of Kants philosophy from K?nigsberg to Canton. But a more convincing argument than any is to show that Greek philosophy in its historical evolution exhibits a perfectly natural and spontaneous progress from simpler to more complex forms, and that system grew out of system by a strictly logical process of extension, analysis, and combination. This is what, chiefly under the guidance of Zeller, we shall now attempt to do.
