The Philosophy of Religion of G.W.F Hegel begins with the thought of God, which is the result, he says, of the other parts of his philosophy. But God is at the same time the Prius that eternally manifests itself. He is the result only in the sense of being the goal of philosophy. There are three stages in the movement of philosophy towards truth: first, the logical, or stage of pure thinking; second, nature; third, finite spirit. From finite spirit we move upward to God, who is the last result of philosophy. The result is the absolute truth. The last becomes the first. God is thus at once the presupposition and the goal of all Hegel's thinking. A reason-derived knowledge of God is the highest problem of philosophy. God is for him the self-conditioning, self-centered totality of all that is, i.e., the ultimate unity. But philosophy must not remain standing with the bare assertion that God is the ultimate unity. It must specify this unity and exhibit it as a concrete system of differences. Philosophy knows God essentially as concrete, spiritual, real universality, that is not grudging but communicates himself. The different parts of Hegel's system are expositions of different aspects of God's existence. Taken together they exhibit the development in that process of concretion or specification which it is the task of philosophy to show forth, as Hegel is always telling us.
