In this study of Robert Boyle’s epistemology, Jan W. Wojcik reveals the theological context within which Boyle developed his views on reason’s limits. After arguing that a correct interpretation of his views on ‘things above reason’ depends upon reading his works in the context of theological controversies in seventeenth-century England, Professor Wojcik details exactly how Boyle’s three specific categories of things which transcend reason - the incomprehensible, the inexplicable, and the unsociable - affected his conception of what a natural philosopher could hope to know. Also covered in detail is Boyle’s belief that God had deliberately limited the human intellect in order to reserve a full knowledge of both theology and natural philosophy for the afterlife.
