“All creatures depend no less on God than lines on the point; they have no beauty nor anything agreeable except that which they receive from the presence of God, who creates them perpetually, just as nothing is perfect in creatures except for God. Hence the greater the beauty in creatures, the more assistance God gives to them; and the greater the quantity of light which he dispenses to them and with which he illuminates them; just as numbers are greater according to the greater multitude of rays which unity sends out to them, and to which it communicates itself more fully; just as one can say that all possible numbers are nothing other than unity made common, or the love, perfection, and communication of unity without which no number can exist.

        Now consonances depend on the unison as lines on the point, numbers on unity, and creatures on God: this is why they are sweeter as they approach closer to it, for they have nothing sweet or agreeable but what they borrow from the union of their sounds, which is the greater as it tends more toward the unison…..

        …..when one knows the art and practice of meditation on true pleasure, one will soon discover that the eternal ideas are its only true object, and consequently that we err in believing that Beauty has her seat in the existence of creatures distinct or separate from the existence of the Creator. For beauty, and that which we call agreeable in sensible or intelligible things, depends on the uncreated Being, just as numbers depend on unity, lines on the point, time on the moment, movement on the motionless, and consonances on the unison.”
