“Human knowledge as human activity has its ultimate ground in God. Such knowledge involves at once a knowledge of God, of the universe, and of human selves. Since man is by creation a psychosomatic entity, his knowledge involves intuition, religious faith, psycho-introspection and -extrospection, as well as sense perception. But what makes human knowledge ultimately possible is God’s revelation of himself and of the universe he orders and in and through which he also make himself known.”
—God, Revelation & Authority, vol. 5, 384.
