Garber (philosophy, Princeton U.) was invited to deliver the 2009 Aquinas Lecture, an annual event sponsored by the Wisconsin-Alpha chapter of Phi Sigma Tau at Marquette University. He explores the consequences of French philosopher Blaise Pascal's (1623-62) famous conclusion that believing in a God that did not exist was safer than not believing in one that did. Among the aspects he ponders are self-deception and deciding to believe, non-cognitivity and contingency, and rationality and history.
