Abstract
For the first time a complete medieval logical textbook has now been translated into English, accompanied by a lengthy introduction and very full notes. The original Latin text is not presented, but key sections of it are added in brackets at appropriate points. In general, the contents of this volume would serve quite well as an initiation into the style, topics and history of medieval logic, as well as into some of the discussions which currently centre around that logic. They would have served even better had the translation been accompanied by the Latin text, since anyone interested enough to pursue the notes would surely have some acquaintance with the Latin which is essential for study in this field. It is hence rather difficult to imagine the exact type of student for whom the book as it stands is intended.
