First Published in 1939 The Philosophy of Courage talks about Philip Leon's personal experience of God in the language of philosophy. It is a book on philosophy but also a book based on personal experience. Leon was the first philosopher to attempt to talk about some of the most important principles of the Oxford Group, and hence the first philosopher to attempt to discuss some of the most important ideas underlying the twelve-step program. He discusses themes like true religion; undeniable facts; demonstration by experiment; spreading the world revolution; sin of depersonalisation; sex and marriage; and philosophy and art. This is an interesting read for scholars of religion, philosophy and theology.
