Of God and His Creatures

Taken by itself, this chapter might seem to argue that God wills the existence of all things that He understands as possible, and that He necessarily wills the existence of things outside Himself, and so necessarily creates them. These conclusions are rejected in Chap. LXXXI. Though God understands all things possible, He does not will them all. If He willed them all, they would all be, which is absurd. It is impossible for all things severally possible ever to come to be conjunctively realised in actuality.
