"Invaluable for those who are concerned with the teaching of medieval philosophy or for those who are interested in research in medieval philosophy. Scholarship of a very high order is revealed everywhere in this work but the manner in which the author transcends mere scholarship and captures in a comprehensive grasp the grand perspectives of the medieval tradition in philosophy is the work of philosophical genius."
~Franciscan Studies
"A comprehensive analysis of philosophical thought from the second century to the fifteenth century, from the Greek apologists through Nicholas of Cusa. This work is Gilson's magnum opus."
~Jounral of the History of Ideas
"The title conveys precisely how Professor Gilson approaches his material. This is a history of philosophy, but of the philosophy of Christians who employ and adapted the ideas of classical philosophy in constructing a rational view of the world in harmony with Christian thought."
