honor of William Wainwright, this article takes up his interest in interreligious dialogue. It pursues two goals simultaneously: One is to provide a better model for understanding philosophy of religion. Terrence Tilley claims that there is the standard model which is mistaken in that it takes arguing for religious beliefs to be equivalent to justifying commitment to a religion. He promotes a practical model , which has its ancestry in the writings of Michel de Montaigne and Blaise Pascal. This model begins with the lived practices of religion and justifies its intellectual content as explanation for the rightness of this way of life. Wainwright’s work fits into the practical model, but Tilley provides a description and a stronger basis for it. The second goal is to provide much more adequate epistemological resources than those used by the standard model, with contributions from Catholic modernist theologian George Tyrrell, recent philosopher of science Imre Lakatos, and Alasdair MacIntyre, who became interested in evaluating traditions, in science, in moral reasoning, and finally what he came to call large-scale traditions. The problem he needed to overcome is the fact that such traditions carry their own, often different, concepts of reasoning. The possibility of fruitful rational conversation between religions is illustrated here by an account of dialogue between Christianity and Shi’ia Islam, as exemplified in David Burrell’s ability to use conversation with Islamic thought to clarify for Christians their own doctrines of the Trinity, the mediation of Christ, and original sin.
