This volume presents the Latin critical edition, with English translation on facing pages, of six questions from Robert Greystones's Sentences commentary. Greystones's discussions provide an excellent window onto debates concerning the will at Oxford in the early 1320s, since he works out his solutions in critical dialogue with contemporaries such as William of Ockham, William of Alnwick, Robert Cowton, Richard Conington, Henry of Harclay, and Peter Aureol. In order to show the cut and thrust of these debates, the editors include many ample quotations from these thinkers, including material found only in manuscript. A clear and extensive introduction describes Greystones's life and doctrine of the will. The editors also provide a complete list of Greystones's numerous questions in the four books of his commentary, found only in Westminster Abbey MS 13.
