The essays in The Intellectual Dynamism of the High Middle Agespay tribute to the work and impact of Constant J. Mews, in spirit and in content, revealing a nuanced and integrated vision of the intellectual history of the medieval West. Mews's groundbreaking work has revealed the wide world of medieval letters: looking beyond the cathedral and the cloister for his investigations, and taking a broad view of intellectual practice in the Middle Ages, Mews has demanded that we expand our horizons as we explore the history of ideas. Alongside his cutting-edge work on Abelard, he has been a leader in the study of medieval women writers, paying heed to Hildegard and Heloise in particular. In Mews' Middle Ages, the world of ideas always belongs to a larger world: one that is cultural, gendered, and politicized.
