This volume brings together Professor Cranz's published studies on Nicholas of Cusa with a set of seven papers left unpublished at the time of his death. Their subjects are the speculative thought of Cusanus and his relationship with the broader themes of the Renaissance. Particular attention is given to patterns of development in Cusanus' thought as he wrestled with problems of divine transcendence and the limits of human capacities. Overall, these studies also reveal Professor Cranz's interest in the larger changes in Western modes of thought during the Middle Ages and the Renaissance, which define our ways of thinking as different from those of Antiquity.
