Brenda Deen Schildgen takes a new path in Chaucer studies by examining the Canterbury Tales set outside a Christian-dominated world -- tales that pit Christian teleological ethics and history against the imagined beliefs and practices of Moslems, Jews, pagans, and Chaucer's contemporaries, the Tartars.Schildgen contends that these tales -- for example, the Knight's, Squire's, and Wife of Bath's -- deliberate on the grand rifts between the Christian or pagan past and Chaucer's present and between other cultural worlds and the Latin Christian world. They offer philosophical views about what constitutes "wisdom" and "lawe" while exploring alternative moral attitudes to the Christian mainstream of Chaucer's time. She argues that their presence in the Canterbury Tales testifies to Chaucer's literary secularism and reveals his expansive narrative interest in the intellectual and cultural worlds outside Christianity.Making impressive use of medieval intellectual history, Schildgen shows that Chaucer framed his tales with the diverse philosophies, religions, and ethics that coexisted with Christian ideology in the late Middle Ages, a framework that emerges as political and not metaphysical, putting these beliefs deliberatively in the context of literary discourse, where their validity can be accepted or dismissed and, most important, debated.
