 Process theism provides an account of the mechanics of omniscience—that is, an account of how God knows the world—that fits well with analogies drawn from experience. Apart from complications introduced by quantum physics, events do not occur because we know about them; we know about them, in part, because they occur. Process theism applies the same logic to God. This account differs from traditional views in two important ways. First, many theists follow Aquinas in reversing the cognitive relation in God. For Aquinas, God knows events in the world because God is their cause (Summa Theologica I, Q. 14, a. 11). This allows Aquinas to affirm omniscience while denying real relations in God; however, it also makes an unambiguous affirmation of the contingency of creaturely decisions difficult if not impossible, as we have already seen in our discussion of God and creativity. Second, the process view contradicts the Boethian concept of eternity as a non-temporal viewpoint on temporal events. For Boethius (and for Aquinas) events in time are related to God as the points on the circumference of a circle are related to its center (Consolation of Philosophy, bk 5, prose 6; Summa Contra Gentiles I, ch. 66, para. 7). For process thought, time is more like a line being added to from moment to moment, but never complete, so there is no vantage from which it can be taken in all at once (Hartshorne 1945, 284).
