1 This proposition is evident from Prop. iii. of this 2 Part. We there drew the conclusion, that God can form the idea 3 of his essence, and of all things which follow necessarily 4 therefrom, solely because he is a thinking thing, and not because 5 he is the object of his own idea. Wherefore the actual being of 6 ideas owns for cause God, in so far as he is a thinking thing. 7 It may be differently proved as follows: the actual being of 8 ideas is (obviously) a mode of thought, that is (Part i., Prop. 9 xxv., Coroll.) a mode which expresses in a certain manner the 10 nature of God, in so far as he is a thinking thing, and therefore 11 (Part i., Prop. x.) involves the conception of no other attribute 12 of God, and consequently (by Part i., Ax. iv.) is not the effect 13 of any attribute save thought. Therefore the actual being of 14 ideas owns God as its cause, in so far as he is considered as a 15 thinking thing, &c. Q.E.D. 16 17
