This course will be a critical examination of a method known as Perfect Being Theology. Most associated with Anselm of Canterbury, Perfect Being Theology attempts to determine the attributes of a divine being from the supposition of its absolute perfection. Common in all of the Abrahamic faiths, it is increasingly popular among philosophers of religion. The course asks questions: what kinds of inference do practitioners of perfect being theology make? What presuppositions underlie the method, and do they face challenges from the facts of religious diversity? Are there alternative theological methods that have been overlooked or ignored?
