JOHN E. MURDOCH AND EDITH DUDLEY SYLLA INTRODUCTION Conferences and colloquia are held and their results often published, but very rarely is any account ...

In a long question, "Whether there is motion to quality," which became part of his Oxford Expositio omnium librorum Physicorum cum questionibus optime disputatis, composed before 1310, Walter Burley supported the succession-of-forms theory of qualitative change. After commenting on Peter Lombard's Sentences at Paris, Burley took part in disputations on controversial questions in the early 1320s, resulting in his De primo et ultimo instanti and his Tractatus Primus and Tractatus Secundus de intensione et remissione formarum. In these independent controversial works, (...) Burley advanced and defended the succession-of-forms theory with greater detail and precision. This paper examines the treatment of the mathematics of alteration in Burley's final Parisian Expositio in libros octo de physico auditu in light of this earlier controversial work. (shrink)

As its modern edition appears in the Synthese Historical Library, Adam WodehamThis book is an important contribution to the history of philosophy.It will be of interest to all medievalists, particularly to those concerned with medieval science, philosophy, and logic. Theologians and historians of mathematics will also find it useful.Whether charity or [any] other incorruptible form is composed of indivisible forms.Because this difficulty is the same for all composite divisible things, whether intensive or extensive, which are of one and the same (...) species or homogeneous, therefore I will briefly inquire indifferently concerning the former and the latter.” 3 The solutions Wodeham then proposes to the questions he asks rely nearly always on logic.

In his De primo et ultimo instanti, Walter Burley paid careful attention to continuity, assuming that continua included and were limited by indivisibles such as instants, points, ubi, degrees of quality, or mutata esse. In his Tractatus primus, Burley applied the logic of first and last instants to reach novel conclusions about qualities and qualitative change. At the end of his Quaestiones in libros Physicorum Aristotelis, William of Ockham used long passages from Burley’s Tractatus primus, sometimes agreeing with Burley and (...) sometimes disagreeing. How may this interaction between Burley and Ockham be understood within its historical context? (shrink)

The core Oxford Calculators developed a science of kinematics in which the key concept was the "latitude of velocity." Based upon the concept of "latitude," the Calculators developed parts of a mathematical physics in deductive format that could be applied to quite various situations.

Ibn Rushd (1126-1198), or Averroes, is widely known as the unrivalled commentator on virtually all works by Aristotle. His commentaries and treatises were used as manuals for understanding Aristotelian philosophy until the Age of the Enlightenment. Both Averroes and the movement commonly known as 'Latin Averroism' have attracted considerable attention from historians of philosophy and science. Whereas most studies focus on Averroes' psychology, particularly on his doctrine of the 'unity of the intellect', Averroes' natural philosophy as a whole and its (...) influence still remain largely unexplored. This volume aims to fill the gap by studying various aspects of Averroes' natural philosophical thought, in order to evaluate its impact on the history of philosophy and science between the late Middle Ages and the Early Modern Period.

Aristotelian philosophy is generally regarded as incompatible with the mathematical methods and principles that form the basis of modern science. This book offers an entirely new perspective on this presumed incompatibility. 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 the Calculators' techniques of quantification expanded the conceptual and methodological limits of Aristotelianism. In the process, it examines a large number of authors, (...) some of them never studied in this context. Exploring the relationship between various late medieval disciplines, the book sheds new light on the problem of continuity vs. discontinuity between scholasticism and modern science. Beyond its historiographical purpose, this book also hopes to be a source of inspiration for present-day philosophers of science. (shrink)
