Thomas Williams presents the most extensive collection of John Duns Scotus's work on ethics and moral psychology available in English. John Duns Selected Writings on Ethics includes extended discussions-and as far as possible, complete questions-on divine and human freedom, the moral attributes of God, the relationship between will and intellect, moral and intellectual virtue, practical reasoning, charity, the metaphysics of goodness and rightness, the various acts, affections, and passions of the will, justice, the natural law, sin, marriage and divorce, the justification for private property, and lying and perjury.
Relying on the recently completed critical edition of the Ordinatio and other critically edited texts, this collection presents the most reliable and up-to-date versions of Scotus's work in an accessible and philosophically informed translation.
John Duns, commonly called Duns Scotus (c. 1266 – 1308), is generally considered to be one of the three most important philosopher-theologians of the High Middle Ages. Scotus has had considerable influence on both Catholic and secular thought. The doctrines for which he is best known are the "univocity of being," that existence is the most abstract concept we have, applicable to everything that exists; the formal distinction, a way of distinguishing between different aspects of the same thing; and the idea of haecceity, the property supposed to be in each individual thing that makes it an individual. Scotus also developed a complex argument for the existence of God, and argued for the Immaculate Conception of Mary.
Duns Scotus was given the scholastic accolade Doctor Subtilis (Subtle Doctor) for his penetrating and subtle manner of thought. He was beatified by Pope John Paul II in 1993.
