The work before us is an extremely valuable contribution to the history of mediæval philosophy, and Mandonnet has the good fortune to treat one of the most interesting periods in this history. The word Averroism at once suggests the excellent treatise of that master, Renan, Averroës et l’Averroïsme. In broad outline the subject is there laid down in masterly fashion once for all.
