1 All things which are, are in God, and must be 2 conceived through God (by Prop. xv.), therefore (by Prop. xvi., 3 Coroll. i.) God is the cause of those things which are in him. 4 This is our first point. Further, besides God there can be no 5 substance (by Prop. xiv.), that is nothing in itself external to 6 God. This is our second point. God, therefore, is the 7 indwelling and not the transient cause of all things. Q.E.D. 8 9
