Historians of fourteenth-century science have long recognized the extraordinary work at both Oxford and Paris in which natural philosophy was becoming highly mathematical. The movement to subject natural philosophy to a mathematical analysis and to quantify such qualities as heat, color, and of course speed surely stands as one of the most significant aspects of late medieval science. Yet as Edith Sylla has observed, because qualities and quantities pertain to different categories in Aristotelian theory, one might expect Aristotelian theorists to (...) avoid quantifying qualities. Even more serious still, the very task of quantifying physical qualities exposes a tension in the nature of science that was discussed first by Aristotle in his Posterior Analytics. (shrink)

Both Pierre Duhem and his successors emphasized that medieval scholastics created a science of mechanics by bringing both observation and mathematical techniques to bear on natural effects. Recent research into medieval and early modern science has suggested that Aristotle's subalternate sciences also were used in this program, although the degree to which the theory of subalternation had been modified is still not entirely clear. This paper focuses on the English tradition of subalternation between 1310 and 1350, and concludes with a (...) discussion of the theory advanced by Thomas Claxton early in the fifteenth century.

From the early thirteenth century, when Alexander of Hales began to use his lectures on Peter Lombard’s Sentences as a vehicle that provided a comprehensive treatment of theological doctrine to his Parisian students, commentaries on the Sentences began a gradual metamorphosis that transformed their use within the theological faculty. By the 1320s, commentaries on the Sentences had ceased to provide a comprehensive treatment of all four books, at the same time they were becoming ever longer. Part of the transformation included (...) an increasing injection of philosophical content into the commentaries, which in turn altered both the theological enterprise and the philosophical foundation on which it rested. This paper provides a preliminary picture of this transformation by looking at some of the issues that excited late-medieval lecturers on the Sentences. (shrink)

The publication of this volume appears to be the most recent in a group of works whose appearance marks renewed interest in Duhem. Over the past ten years, attention has been focused on Duhem's life (Jaki 1984), his physics (Jaki 1984; Nye 1986, 208–23), his philosophy of science (Jaki 1984, chap. 9; Paul 1979, chap. 5; Ariew 1984),' and his history of science (Jaki 1984, chap. 10; Martin 1976). But the significance of this translation is that - leaving asideTo Save (...) the Phenomena– for the first time we have a partial translation into English of one of the two great historical works that revitalized the study of medieval science.
