Moreover, Lewiss long journey to Christianity was essentially philosophical passing through seven different stages. This journey, as well as every philosophical topic Lewis discussed, including metaphysics, natural theology, epistemology, logic, psychology, ethics, socio-political philosophy, and aesthetics are explained here in detail. Barkman incorporates previously unexplored treasures from Lewiss unpublished philosophy lecture notes, lost philosophical essays, and hand-written annotations from copies of his philosophical books, such as Aristotles Ethics and Augustines City of God. _._._._._ Indispensable ~ Dr. James Como, author of Remembering C.S.
