Rights, Laws and Infallibility in Medieval Thought

Book excerpt: The papers collected in this volume fall into three main groups. Those in the first group are concerned with the origin and early development of the idea of natural rights. The author argues here that the idea first grew into existence in the writings of the 12th-century canonists. The articles in the second group discuss miscellaneous aspects of medieval law and political thought. They include an overview of modern work on late medieval canon law. The final group of articles is concerned with the history of papal infallibility, with especial reference to the tradition of Franciscan ecclesiology and the contributions of John Peter Olivi and William of Ockham.
