 The question of the metaphysical relation of God and creativity is a watershed between process theism and more traditional forms of theism. Process philosophy, modifying a statement from Plato’s Sophist (247e), affirms that the most concrete real beings—in Whitehead’s language, actual entities—are characterized by the power to act and to be acted upon (Plato says real beings act or are acted upon). In process metaphysics no actual entity is wholly determined by the activity of another; or phrased positively, every actual entity retains some power of self-determination, however minimal or slight it may be. According to this view, to have power in relation to others is to have power in relation to other entities with some degree of power. This is process philosophy’s doctrine of universal creativity. Hartshorne says, “To be is to create” (Hartshorne 1970, 1, 272). The logic of the matter does not change if God is included in the metaphysical scheme. For process theism, God is the supreme or eminent creative power, but not the only creative power. Thus, process theists speak of God and the creatures as co-creators (Hartshorne and Reese 1953 [2000, 140]; Hartshorne 1967a, 113).
