 It is certain that things conform to the idea that God has of them. For since God created them, He can only have made them according to the idea that He has of them. Now according to the opinion that I maintain, the idea that I have of extension in length, breadth, and depth is not a modification of my soul: it is eternal, immutable, necessary, common to God and all intelligences, and this idea is the model of created extension from which all bodies are formed. I can thus affirm with truth of created extension what I see contained in this uncreated idea. (OCM 9:925–6)
