By the side of this wisdom there was found everywhere the Magic of the sorcerer,—a knowledge which was authenticated by command over outward things. But it was only in the priestly circles of ancient Babylonia,—under what influences and to what extent we do not precisely know,—that men rose to a more scientific consideration of the world. Their eyes were turned from the confusion of earthly existence to the order of the heavens. They were not like the Hebrews, who never got beyond the wondering stage [5], or who saw merely an emblem of their own posterity in the countless stars [6]; they resembled rather the Greeks who came to understand the Many and the Manifold in their sublunary forms, only after they had discovered the harmony of the All in the unity and steadiness of the movement of the heavens. The only drawback was that much mythological by-play and astrological pretence was interwoven with what was good, as in fact was the case also in Hellenism. This Chaldaean wisdom, from the time of Alexander the Great, became pervaded, in Babylonia and Syria, with Hellenistic and later with Hellenistic-Christian ideas, or else was supplanted by them. In the Syrian city of Harran only, up to the time of Islam, the old heathenism held its ground, little affected by Christian influences. (Cf. I, 3, § 4). 2. Of more importance than any Semitic tradition, was the contribution made to Islam by Persian and Indian wisdom. We do not need to enter here upon the question as to whether Oriental wisdom was originally influenced by Greek philosophy, or Greek philosophy by Oriental wisdom. What Islam carried away directly from Persians and Indians may be learned with tolerable certainty from Arabic sources, and to this we may confine ourselves. Persia is the land of Dualism, and it is not improbable that its dualistic religious teaching exercised an influence upon theological controversy in Islam, either directly or through the Manichaeans and other Gnostic sects. But much greater, in worldly circles, was the influence wielded by that system which, according to tradition, came to be even publicly recognized, under the Sasanid Yezdegerd II (438/9–457), viz. Zrwanism (Cf. III, 1, § 6). In this system the dualistic view of the world was superseded by setting up endless Time, (zrwan, Arab. dahr) as the paramount principle, and identifying it with Fate, the outermost heavenly sphere or the movement of the heavens. This doctrine, pleasing to philosophic intellects, has secured, with or without the guise of Islam, a prominent place for itself in Persian literature and in the views of the people, up to our own day. By theologians, however, and no less by philosophers of the Idealistic schools, it was disavowed as Materialism, Atheism and so forth.
