Emanationism

Of course emanationism assumes the existence of two coeternal realities, one spiritual and the other material. This, Aristotle would allow, for he regarded matter as immortal, without beginning or end. He also accepted the eternity of spirit. The existence of two eternal principles endeared Aristotle to the Churchmen because they found in his doctrine the comfort they sought for their own belief in the eternity of good and evil and the endless warfare between God and the Devil..Apparently Manly P. Hall in his own book, "The Wisdom of the Knowing Ones: Gnosticism: The Key to Esoteric Christianity".
