THE pervasive role of causality in the development of Galileo's science has been obscured largely by two factors. Philosophers who address the problem usually exhibit an anti-causal bias traceable to David Hume, and this disposes them to concentrate on passages in Galileo's writings that can be given a positivist interpretation. Historians are likewise selective in their treatment of his texts, for they tend to enforce sharp dichotomies between Galileo's earlier Latin compositions and his treatises in Italian, especially the two dialogues (...) of his later years for which he is justly famous. With this twofold reinforcement from philosophers and historians of science, one might think that the problem of causality in Galileo's science is whether or not the Italian physicist actually reasoned in causal terms such as those explained in Aristotle's Posterior Analytics. A large and influential school at the moment would say that this is the question, and that it is best answered in the negative: causal analysis played little or no role in the development of Galileo's science, and certainly less and less in his later years. Indeed, it was his rejection of Aristotle precisely on these grounds that merits for him the title, "Father of Modern Science," the canons of which science are almost diametrically opposite those of the science advocated by Greek peripatetics and medieval scholastics, before the onset of the modern era.

The aim of this paper is to report some little-known aspects of sixteenth-century physics as these relate to the development of mechanics in the seventeenth century. The research herein reported grew out of a study on the mechanics of Domingo de Soto, a sixteenth-century Spanish scholastic,1 which has been concerned, in part, with examining critically Pierre Duhem's thesis that the English “Calculatores” of the fourteenth century were a primary source for Galileo's science.2 The conclusion to which this has come, thus (...) far, is that Duhem had important insights into the late medieval preparation for the modern science of mechanics, but that he left out many of the steps. And the steps are important, whether one holds for a continuity theory or a discontinuity theory vis-à-vis the connection between late medieval and early modern science. (shrink)
Contemporary thinkers who address the problem of causal relations generally favor Hume’s analysis, although some periodically manifest interest in Aristotle’s exposition as an important and viable alternative. Few, however, find among the many philosophers who came between Aristotle and Hume any worthwhile contributor to the development of this problematic. Some might note, for example, Nicholas of Autrecourt as a medieval precursor of Hume, but this merely keeps the discussion fluctuating between the same two poles. This essay aims to call attention (...) to a different and intermediate view, not hitherto noted, that was proposed in the High Middle Ages by Thomas Aquinas. It argues that Aquinas made a significant advance beyond Aristotle in his analysis of antecedent causation, and thereby made possible the certification of some elements in Hume’s analysis, without subscribing to its more extreme results. In so doing, moreover, Aquinas adumbrated some problems in contemporary analytic discussions of the causal relationships between events, and consequently may shed light on their solution. (shrink)
This edition, with translation and notes, by an outstanding historian of medieval optics, should serve to make Roger Bacon better understood and appreciated by those interested in the history of Western thought. Some time ago Bacon was lauded as a precursor of modern science, as an inventor, an innovator in the use of experimental and mathematical methods, a man ahead of his time whose genius went unnoticed by his contemporaries. Then a reaction set in, and the claim was made that (...) his results were all anticipated by others, especially by Robert Grosseteste, and that he had really contributed little to the advance of scientific knowledge. Lindberg sets the record straight in his careful and documented study of these seminal writings. As he notes in summary: "[T]his work did not foreshadow the science of subsequent ages...; rather, it represents an intelligent and creative response to a variety of ancient traditions. Bacon did not possess a seventeenth-century or twentieth-century mind, but a very good thirteenth-century one; and there is no possibility of understanding his achievement unless we view it in medieval context".

This ambitious study, by a professor of rhetoric, proposes itself as "intellectual history in a traditional sense" and not as philosophical discourse. Though philosophy does not appear in its title, however, much of its content will appear to philosophers as pertaining to their discipline, and the thesis it develops surely commends itself to philosophical critique. The author's aim, at least in part, is to challenge "the commonly held view" that the scientific revolution created or intensified the modern division between the (...) humanities and the sciences. In the early Renaissance, she argues, rhetoric and philosophy were seen as "pursuing different goals by different means," with rhetoric assigned to the humanities and concerned with opinion and probability and science assigned to philosophy and concerned with truth and certainty. Such a dichotomy was broken down at the onset of the modern period, she holds, particularly in seventeenth-century England, where a sceptical approach to knowledge made for common ground between humanists and scientists. The weakening of knowledge claims in the probabilistic empiricism of the period is thus, for her, the key to understanding its intellectual life and the climate of opinion in which it flourished. To make the point she devotes successive chapters to natural philosophy and empirical science; religion; history; law; witchcraft; and language, communication, and literature. The presentation is scholarly throughout and well documented in an abundance of notes at the end of the volume. Considering the difficulty of her thesis and its extremely broad range the author argues her case well; yet there are problems with it that make one wonder whether her generalization can claim validity in anything more than a trivial sense.
