An edited text of the teaching of Adam of Bockenfield, a key figure in the history of the introduction of Aristotle's natural philosophy in England. It offers an edition of three early Latin commentaries on the tract On memory and recollection, all of them produced in the nascent Faculty of Arts at the University of Oxford.The book consists of three main sections. The introduction to the critical edition enlightens the complex history of the manuscripts and the scientific method followed by the editors. The historical and doctrinal introduction tries to illustrate the difficult reception of Aristotelian theories of memory in a context where other competing theories pre-existed and where natural philosophy as a university discipline was in the process of being built at Oxford. The last section consists of the critical edition of the Latin text of three commentaries on the De memoria et reminiscentia by Aristotle, two anonymous and one by Adam of Bockenfield, as well as in the English translation of the latter.
