 God is a “nothingness” (nihilum) whose real essence is unknown to all created beings, including the angels (447c). Indeed, Eriugena argues in a radical manner, following Maximus Confessor, that God’s nature is infinite and uncircumscribable, such that He is unknown even to Himself, since He is the “infinity of infinities” and beyond all comprehension and circumscription. In the Periphyseon, Eriugena repeats the position of the De Praedestinatione that God does not know evil, and, in a genuine sense, God may be said not to know anything; his ignorance is the highest wisdom.
