But if God is the ultimate source of all concrete, individual things and events, then God Himself must be concrete, and individual in the highest degree. Unless the origin of all other things were itself concrete and individual, nothing else could be so; for there is no conceivable means whereby what is abstract or general could itself produce concrete reality. . . . If anything is to exist at all, then the Original Thing must be, not a principle nor a generality, much less an “ideal” or a “value,” but an utterly concrete fact. (C. S. Lewis, Miracles)
