After majoring in philosophy at Harvard, Tom Cathcart pursued the usual philosophical career. He was a probation officer, worked with street gangs in Chicago, did similar work with doctors for Blue Cross and Blue Shield, and was COO of a hospital, all the while going to and dropping out of various divinity schools. His essay, "The Ontological Argument Works! (sort of)" appeared recently in Theology Today. In addition to "Heidegger and a Hippo Walk through Those Pearly Gates," Tom and Daniel Klein have written the New York Times bestseller, "Plato and a Platypus Walk into a Bar," "Aristotle and an Aardvark Go to Washington," and the politically-incorrect book of daily affirmations, "Macho Meditations."
