In this lecture, Professor Kozlowski transitions from Ancient to Medieval philosophy, discussing the thousand years of history that transpires to contextualize this period, as well as the key arguments of Anselm and Thomas Aquinas about the existence and nature of God, the connection between reason and revelation, and the medieval notion of God's simplicity. For his next lecture he will explain quantum mechanics, the history of alchemy, and Hegelian metaphysics, all while gargling salt water and spinning plates on his nose.
