Bøker av Guillelmus de Aragonia

Working in a renewed Aristotelian tradition, Guillelmus de Aragonia wrote De nobilitate animi, "On Nobility of Mind," around 1280-1290 and taught that true nobility is an acquired, not inborn, quality. This edition, based in part on hitherto unknown manuscripts, presents the Latin text with an English translation, an introduction, and appendix.
