"This book is quite simply the most important, intellectually ambitious, and far-reaching endeavor in recent years."-Stephen G. Nichols, Johns Hopkins University "An invaluable resource not only for students of French medieval literature but for any reader interested in the conjunction of philosophy and poetry."-Speculum "In Kay's book we discover an extraordinary piece of scholarship that refuses to be contained, much like the philosophical inquiry she examines, and that demands a complete shift both in the way we approach late-medieval didactic literature and in literary scholarship as practiced today."-The French Review
