"Klima has produced an impressive volume, with texts on a wide variety of medieval philosophical discussion points that show the range of views and, broadly speaking, the trajectory of historical development on the individual issues. The translations themselves are first rate, several appear for the first time in this volume, and they are accompanied by expert introductions and annotations, as well as by a guide to further reading.... Klima's anthology of medieval philosophical texts will serve well as a course textbook or for a reader interested in getting an idea of some main issues in medieval philosophy and some important medieval views on those issues."
