The papers in this volume fall into four sections. The first part deals more generally with heresy, religious movements and the Church, while the second focuses on Wyclif, covering his path to dissent, his religious doctrines, and a doctrinal comparison with Hus. Philosophical themes come to the fore in the third section, which has papers on the decline of scholasticism in the 14th century and on the trivium, and also includes hitherto unpublished essays on the theology of Augustine's two cities and on Ockham and nominalism. The final part, with another two papers published here for the first time, discusses Christian, Augustinian and Franciscan concepts of man, and the concepts of natural rights according to Ockham and the Franciscans.
