702pp. Two volume, seven quodlibet edition of a major philosophical work of medieval times. Bright, tightly bound and unmarked, condition as new with minor shelfwear to the spines of both books (see photo). Blurb reads: 'William of Ockham (c.1285-1347) was the preeminent Franciscan thinker of the 14th century and is generally acknowledged to be a pivotal figure in the transition from the high Aristotelianism of the 13th century to the revolutions in philosophy, theology, and science which mark the Renaissance. Though Ockham was born in England and educated at Oxford, only a small fraction of his corpus has been hitherto translated into English. This two-volume set, the first English translation of "Quodlibetal Questions", is based on the new critical edition of Ockham's theological and philosophical works. The work, most likely written in the early 1320s when Ockham was living in London, comprises mature discussions of many of his favourite topics in logic, ontology, natural philosophy, philosophical psychology, moral theory, and theology. It serves as an introduction to his philosophical method as well as to his characteristic doctrines.;The "Yale Library of Medieval Philosophy" series makes available works of the Middle Ages in accurate English translations. Each volume provides a brief introduction, notes and a detailed index.'
