Theology lost its undisputed control and became dependent on philosophy. Consequently, it experienced the influence of Descartes and Wolff, of Kant and Fichte, and of Hegel and Schelling.

One could almost say that the study of philosophy is as essential for understanding the principles of contemporary theology as that of the theology itself.
