This volume explores the relationship between individuals and institutions in scholastic thought and practice across the twelfth and fifteenth centuries, taking a broad approach to scholasticism in its inclusion of ethics, history, heresy, law, inquisition, metaphysics, pastoral care, poetry, religious orders, saints' cults and theology. It addresses two major questions: what was the relationship between particular intellectuals and their wider networks; and how did individuals alter their institutions, and likewise, these institutions shape these individuals? This book is of major importance to intellectual, religious and cultural historians as well as historians of knowledge and science.
