For Augustin, the possibility of knowledge requires the fundamental reality of one for whom knowledge is perfectly complete. Human knowledge depends on this prior foundational truth. As the human mind is illumined by the divine mind (his theory of illumination), it becomes possible to understand not only something of God's reality, but also the nature of the world in which we find ourselves.
This wide ranging course starts with the pre-Socratic philosophers of the ancient world, and traces the history of philosophical speculation across the ages up to the present. Included along the way is special attention to the greatest Christian thinkers in history, including Augustine, Anselm, Aquinas, Luther, Calvin and many others.
