"It has been 140 years since a full biography of William of Auvergne (1180?-1249), which may come as a surprise, given that William was an important gateway of Greek and Arabic thought and philosophy to western Europe in the thirteenth century, and one of the earliest writers in the medieval Latin west on demonology. Lesley Smith's aims in this book are two-fold: first, to take a closer look at William, the human being, how he saw the world and his place in it; and to uncover William's interactions with his Parisian congregation through the nearly 600 sermons he left after his death. Smith has mined these writings, unremarked in previous scholarship, to give us a different perspective on the schoolmaster, bishop of Paris, and strict theologian we have come to know: a preacher who spoke and ministered not just to the powerful and elite, but also to commoners, to the poor, and to the less fortunate. Through a study of the sermons, Smith creates a broader landscape of William's thought and life, highlighting his attention to the importance--and limits--of language, and his attempts to find a way to address the concerns of the larger populace. In his preaching, we get a sense of the balance William achieved, in the way he communicated religious teachings, in his understanding of the concerns of ordinary Parisians, and in his awareness of the ebb and flow of daily life in a medieval city. The book will interest scholars of intellectual history and philosophy, religion, and literary studies more broadly for Smith's innovative method of excavating the sermons in pursuit of William the person, and his humanity. An altogether "new" William for the twenty-first century"--
