Augustine used neoplatonism selectively. He used both the neoplatonic Nous, and the Platonic Form of the Good (or "The Idea of the Good") as equivalent terms for the Christian God, or at least for one particular aspect of God. For example, God, nous, can act directly upon matter, and not only through souls, and concerning the souls through which it works upon the world experienced by humanity, some are treated as angels.[32]
