 Hartshorne’s dispute with traditional or classical philosophical theism concerns not so much the existence of God, but rather its assumption that the actuality of God (i.e., how God exists) could be described in the same terms as the existence of God. A God who exists necessarily is not necessary or unchanging in every other respect (e.g., in terms of divine responsiveness to creaturely changes), he thinks. Although Hartshorne believes that the medieval thinkers were correct in trying to think through the logic of perfection, he also thinks that this logic has traditionally been misapplied in the effort to articulate the attributes of a being called “God,” roughly defined as the greatest conceivable being. The traditional or classical theistic logic of perfection sees God as monopolar in that regarding various contrasts (permanence-change, one-many, activity-passivity, etc.) the traditional or classical philosophical theist has chosen one element in each pair as a divine attribute (the former element of each pair) and denigrated the other.
