1 Will is only a particular mode of thinking, like 2 intellect; therefore (by Prop. xxviii.) no volition can exist, 3 nor be conditioned to act, unless it be conditioned by some cause 4 other than itself, which cause is conditioned by a third cause, 5 and so on to infinity. But if will be supposed infinite, it must 6 also be conditioned to exist and act by God, not by virtue of his 7 being substance absolutely infinite, but by virtue of his 8 possessing an attribute which expresses the infinite and eternal 9 essence of thought (by Prop. xxiii.). Thus, however it be 10 conceived, whether as finite or infinite, it requires a cause by 11 which it should be conditioned to exist and act. Thus (Def. 12 vii.) it cannot be called a free cause, but only a necessary or 13 constrained cause. Q.E.D. 14 15
