In this edited series of lectures, von Hügel examines the inter-connectedness between finite aspects of human existence (reason) and the reality of the existence of God. Von Hügel aims to offer an analysis of this tension as examined by different historical philosophers and theologians, addressing the issue from different angles, namely epistemology, ethics, and institutional religion.  The lectures, intended for a religious audience, do not attempt to prove the existence of God; much rather, they seek to reveal the link between belief in God and patterns of the mind.
