 Since its inception, Manichaean dualism has been criticized for providing little empirical support for its extravagant cosmology. A second problem is that, for a theist, it is hard to accept that God is not an all-powerful sole creator. For these reasons influential, early Christian philosophers such as Saint Augustine, who initially accepted the Manichaean theory of evil, eventually rejected it in favor of the Neoplatonist approach. (See Augustine, Confessions; On the Morals of the Manichaeans; Reply to Manichaeus; Burt, Augustine’s World.)
