Philosophical Commentary on the Words of the Gospel 'Compel Them to Come In', written by the Protestant philosopher Pierre Bayle in 1686-88, was a classic statement of the case for toleration at a time of extreme persecution. This collection of Kilcullen's writings on Bayle's work examines a wide range of 17th-century religious and philosophical issues, including Bayle's arguments, Arnauld's attack on Jesuit moral theories similar to Bayle's, the uses and limitations of "reciprocity" arguments, the "ethics of belief," and questions of moral responsibility and free will.
