This book offers an introduction to the thought of Robert Holcot, a great and influential but often underappreciated medieval thinker. Holcot was a Dominican friar who flourished in the 1330's and produced a diverse body of work including scholastic treatises, biblical commentaries, and sermons. By viewing the whole of Holcot's corpus, John T. Slotemaker and Jeffrey C. Witt provide a comprehensive account of his thought. Challenging established characterizations of him as a skeptic or radical, they show Holcot to be primarily concerned with affirming and supporting the faith of the pious believer. At times, this manifests itself as a cautious attitude toward absolutist claims about the power of natural reason. At other times Holcot reaffirms, in Anselmian fashion, the importance of rational effort in the attempt to understand and live out one's faith. Over the course of this introduction the authors unpack Holcot's views on faith and heresy, the divine nature and divine foreknowledge, the sacraments, Christ, and political philosophy. They also examine Holcot's approach to several important medieval literary genres, including the development of his unique "picture method," biblical commentaries, and sermons. In so doing, Slotemaker and Witt restore Holcot to his rightful place as one of the most important thinkers of his time.
