The volume offers a critical edition of a text by Richard FitzRalph, one of the most original 14th-century Oxonian thinkers. FitzRalph's philosophical and theological ideas were enthusiastically adopted or fiercely challenged, consolidating his recognition at the universities of Oxford, Paris, and Italy. For all this, his work remains relatively little-known today, an obscurity this book redresses by making a question on the will from FitzRalph's Lectura in Sententias available to a large readership. Besides, FitzRalph's strongly voluntaristic position and analytical techniques derived from the natural sciences and logic are shown to place him close to the Oxford Calculators.
