“How then, Lord, are you all these things? Are they parts of you? Or rather, is not each of them all that you are? For whatever composed of parts is not completely one. ... Therefore there are no parts in you, Lord, and you are not a plurality. Instead, you are so much a unity, so much identical with yourself, that you are in no respect dissimilar to yourself”
(Anselm, Proslogion, ch.18).
