Originally published in 1990, this was the first ever translation or edition of obscure fourteenth-century philosopher Richard Kilvington's work.

Latin text edition of the 14th century product of the philsophers known as the Oxford Calculators - a sophisma being a paradoxical sentence which brings an abstract issue into focus.

Among the commentaries on Aristotle’s Nicomachean Ethics produced in the Middle Ages, that of Richard Kilvington is one of the most thought-provoking. Kilvington adopts a unique perspective of argumentation in which he applies concepts and terminology from the fields of logic and physics to ethical dilemmas. This unprecedented approach allows him to formulate original solutions to various ethical problems. He concentrates on the will, moral weakness, the relationship between the will and prudence, the change of virtues and vices, and the nature of ethical objects. The presented commentary is a valuable record of the philosophical debates at Oxford in the 14th century.

This book offers an entirely new perspective on the alleged incompatibility between Aristotelian philosophy and the mathematical methods and principles that form the basis of modern science. It surveys the tradition of the Oxford Calculators from its beginnings in the fourteenth century until Leibniz and the philosophy of the seventeenth century and explores how their various techniques of quantification expanded the conceptual and methodological limits of Aristotelianism.

This is the first reference ever devoted to medieval philosophy. It covers all areas of the field from 500-1500 including philosophers, philosophies, key terms and concepts. It also provides analyses of particular theories plus cultural and social contexts.

This volume deals with corpuscular matter theory that was to emerge as the dominant model in the seventeenth century. By retracing atomist and corpuscularian ideas to a variety of mutually independent medieval and Renaissance sources in natural philosophy, medicine, alchemy, mathematics, and theology, this volume shows the debt of early modern matter theory to previous traditions and thereby explains its bewildering heterogeneity. The book assembles nineteen carefully selected contributions by some of the most notable historians of medieval and early modern philosophy and science. All chapters present new research results and will therefore be of interest to historians of philosophy, science, and medicine between 1150 and 1750.
