Manichæism

Manichæism, the creed which ascribes the created universe to two antagonistic principles, the one essentially good—God, spirit, light; the other essentially evil—the devil, matter, darkness; and this name is applied to every system founded on the like dualism. Mani, the founder of it, appears to have borrowed his system in great part from Zoroaster.
