Sheldon, Ch. Hist., 1:206—“The Syrians were in general more dualistic than the Alexandrians. Some, after the fashion of the Hindu pantheists, regarded the material realm as the region of emptiness and illusion, the void opposite of the Pleroma, that world of spiritual reality and fulness; others assigned a more positive nature to the material, and regarded it as capable of an evil aggressiveness even apart from any quickening by the incoming of life from above.” Mansel, Gnostic Heresies, 139—“Like Saturninus, Bardesanes is said to have combined the doctrine of the malignity of matter with that of an active principle of evil; and he connected together these two usually antagonistic theories by maintaining that the inert matter was co-eternal with God, while Satan as the active principle of evil was produced from matter (or, according to another statement, co-eternal with it), and acted in conjunction with it. 142—The feature which is usually selected as characteristic of the Syrian Gnosis is the doctrine of dualism; that is to say, the assumption of the existence of two active and independent principles, the one of good, the other of evil. This assumption was distinctly held by Saturninus and Bardesanes ... in contradistinction to the Platonic theory of an inert semi-existent matter, which was adopted by the Gnosis of Egypt. The former principle found its logical development in the next century in Manichæaism; the latter leads with almost equal certainty to Pantheism.”
