In this much-anticipated work, distinguished authors Mary Beth Ingham and Mechthild Dreyer present an accessible introduction to the philosophy of the thirteenth century Franciscan John Duns Scotus

John Duns Scotus is arguably one of the most significant philosopher theologians of the middle ages who has often been overlooked. This book serves to recover his rightful place in the history of Western philosophy revealing that he is in fact one of the great masters of our philosophical heritage. Among the fields to which Scotus has made an immense contribution are logic, metaphysics, philosophy of mind and action, and ethical theory.The Philosophy of John Duns Scotus provides a formidable yet comprehensive overview of the life and works of this Scottish-born philosopher. Vos has successfully combined his lifetime of dedicated study with the significant body of biographical literature, resulting in a unique look at the life and works of this philosopher theologian.

Scotus - unlike Thomas Aquinas - never commented on Aristotle's Politics nor did he write any significant political tracts like Ockham. Nevertheless, despite his primary philosophical reputation as a metaphysician, Scotus did have certain definitive ideas about both politics and the morality of the marketplace.

The Franciscan John Duns Scotus (c. 1266-1308) is the philosopher's theologian par excellence: more than any of his contemporaries, he is interested in arguments for their own sake. Making use of the tools of modern philosophy, Richard Cross presents a thorough account of Duns Scotus's arguments on God and the Trinity. Providing extensive commentary on central passages from Scotus, many of which are presented in translation in this book, Cross offers clear expositions of Scotus's sometimes elliptical writing. Cross's account shows that, in addition to being a philosopher of note, Scotus is a creative and original theologian who offers new insights into many old problems.

The Singular Voice of Being reconsiders John Duns Scotus’s well-studied theory of the univocity of being in light of his less explored discussions of ultimate difference. Ultimate difference is a notion introduced by Aristotle and known by the Aristotelian tradition, but one that, this book argues, Scotus radically retrofits to buttress his doctrine of univocity. Scotus broadens ultimate difference to include not only specific differences, but also intrinsic modes of being (e.g., finite/infinite) and principles of individuation (i.e., haecceitates). Furthermore, he deepens it by divorcing it from anything with categorical classification, such as substantial form. Scotus uses his revamped notion of ultimate difference as a means of dividing being, despite the longstanding Parmenidean arguments against such division. The book highlights the unique role of difference in Scotus’s thought, which conceives of difference not as a fall from the perfect unity of being but rather as a perfective determination of an otherwise indifferent concept. The division of being culminates in individuation as the final degree of perfection, which constitutes indivisible (i.e., singular) degrees of being. This systematic study of ultimate difference opens new dimensions for understanding Scotus’s dense thought with respect to not only univocity, but also to individuation, cognition, and acts of the will.

This book sets out a thematic presentation of human action, especially as it relates to morality, in the three most significant figures in Medieval Scholastic thought: Thomas Aquinas, John Duns Scotus, and William of Ockham
