Proslogion

The supreme Spirit loves himself.

BUT, while I am here considering with interest the individual properties and the common attributes of Father and Son, I find none in them more pleasurable to contemplate than the feeling of mutual love. For how absurd it would be to deny that the supreme Spirit loves himself, just as he remembers himself, and conceives of himself! since even the rational human mind is convinced that it can love both itself and him, because it can remember itself and him, and can conceive of itself and of him; for idle and almost useless is the memory and conception of any object, unless, so far as reason requires, the object itself is loved or condemned. The supreme Spirit, then, loves himself, just as he remembers himself and conceives of himself.
