Saint Anselm,
Monologium — On the Being of God
“ Still, it is apparent that this love can neither be said, in accordance with the usage of common speech, to be unbegotten, nor can it so properly be said to be begotten, as the Word is said to be begotten. For we often say of a thing that it is begotten of that from which it derives existence, as when we say that light or heat is begotten of fire, or any effect of its cause. ”
