This collection of six essays centers on Professor Koyre's great theme: the relative importance of metaphysics and observation, with controlled experiment a kind of marriage between the two. Professor Koyre's thesis might be summed up as a claim that when one is seeking to explain the scientific revolution, attention must be concentrated on the philosophical outlook of the scientist and away from speculative theories.

The problem of Galileo's logical methodology has long interested scholars. In this volume William A. Wallace offers a solution that is completely unexpected, yet backed by convincing documentary evidence. His analysis starts with an early notebook Galileo wrote at Pisa, appropriating a Jesuit professor's exposition of the Posterior Analystics of Aristotle, and ends with one of the last letters Galileo wrote, stating that in logic he has been a Peripatetic all his life. Wallace's detective work unearths the complete logic course (...) from which the notebook was excerpted, then proceeds to show how its terminology and methodology continue to surface in Galileo's later writings in which he founds his new sciences of the heavens and of local motion. The result is a tour de force that commends itself not only to Galileo's scholars and to logicians, philosophers, and historians, but to anyone interested in the epistemic roots of modern science.

Medieval epistemology begins as ideal theory: when is one ideally situated with regard to one's grasp of the way things are? Taking as their starting point Aristotle's Posterior Analytics, scholastic authors conceive of the goal of cognitive inquiry as the achievement of scientia, a systematic body of beliefs, grasped as certain, and grounded in demonstrative reasons that show the reason why things are so. Obviously, however, there is not much we know in this way. The very strictness of this ideal (...) in fact gives rise to a body of literature on how Aristotle's framework might be relaxed in various ways, for certain specific purposes. In asking such questions, scholastic authors are in effect pursuing the project of social epistemology, by trying to adapt their ideal theory to the circumstances of everyday life. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Notes and Discussions GALILEO AND THE SCHOOL OF PADUA The first issue of the Journal of the History of Ideas, appearing in 1940, contained an article on the development of scientific method in northern Italy during the Renaissance and its significance for the growth of modern science. It is no exaggeration to say that this article, by John H. Randall, Jr., has been one of the most important and (...) influential contributions to the history of ideas in recent years, casting new light on a much-neglected tradition (Italian Aristotelianism) and suggesting an entirely different picture of Galileo's relations to the school philosophy of his day. Randall's thesis has won wide acceptance, by such competent and careful scholars as Crombie, Dijksterhuis, Butterfield, and the Kneales. Giacomo Zabarella (1532-1589) has been restored to the high esteem in which he was held in the Renaissance, and has been hailed as the thinker who "summed up the collective wisdom of the Padua school" and "formulated the classic version of their teaching method, in the terms and with the distinctions so fruitfully employed and consciously expressed by Galileo." Now the article has been reprinted (John H. Randall, Jr., The School of Padua and the Emergence of Modern Science [Padua, 1961], 141 pp.) with several other provocative articles reassessing the thought of Pomponazzi and Leonardo Da Vinci, as the first in a series of monographs sponsored jointly by the universities of Padua and Columbia. It has also been incorporated in a chapter of Randall's admirable Career of Philosophy, but without the Latin texts that make the present edition definitive. In the face of the almost universal acceptance of Randall's thesis, I find it an uncongenial task to express a dissenting opinion with regard to its crucial point, namely, the presumed debt of Galileo to Zabarella. Uncongenial, because much of what Randall has urged seems well taken, and because there is an initial attractiveness about the view that philosophical discussions at Padua could have contributed to the birth of the new science. Historians of science are usually so unfair to philosophy that it is refreshing to be able to entertain the view that scientific research may even have received some encouragement from philosophers. And it is prima facie plausible that this encouragement should have come to a focus at Padua in the sixteenth century, for here if anywhere the new science was born. Unfortunately, the resulting picture of Galileo leaves us with some puz- [zz3] 224 HISTORY OF PHILOSOPHY zling facts, or more precisely, non-facts: if we accept it, we are left wondering why there is so little tangible evidence of Zabarella's influence on Galileo. It may well be that there is evidence that I have missed, and for the sake of the reputation and prestige of Italian Aristotelianism, I hope there is. But I should like to present some of the difficulties I have with Professor Randall's thesis, in the hopes that some defender of his view will be inspired to allay my misgivings. Anyone who has ever read a page of Galileo's writings knows how often and violently he expressed his opposition to "the Aristotelians" and with what withering scorn he treated the contemporary representatives of the Peripatetic tradition. He often concedes that Aristotle would have been more flexible than his so-called followers, and would have yielded to new evidence in natural philosophy. But Galileo never admits that Aristotle's followers have developed anything of scientific value in the way of methodology. The methodology of the Aristotelians relied exclusively on the syllogism ; but Galileo specifically insists that the syllogism has no value in scientific discovery, whatever its other uses may be. In the face of these stronglyexpressed and consistently-held attitudes, it is hard to see how Zabarella, a loyal Aristotelian who relied exclusively on the syllogism as the "instrument of science," could have escaped Galileo's general condemnation. This point would lose its force if Galileo had ever expressly singled Zabarella out as a shining exception among the run-of-the-mill Aristotelians. Unfortunately, there is no mention of Zabarella in the whole mass of Galileo 's writings, and there is no evidence that... (shrink)

This paper argues that early modern experimental philosophy emerged as the dominant member of a pair of methods in natural philosophy, the speculative versus the experimental, and that this pairing derives from an overarching distinction between speculative and operative philosophy that can be ultimately traced back to Aristotle. The paper examines the traditional classification of natural philosophy as a speculative discipline from the Stagirite to the seventeenth century; medieval and early modern attempts to articulate a scientia experimentalis; and the tensions (...) in the classification of natural magic and mechanics that led to the introduction of an operative part of natural philosophy in the writings of Francis Bacon and John Johnston. The paper concludes with a summary of the salient discontinuities between the experimental/speculative distinction of the mid-seventeenth century and its predecessors and a statement of the developments that led to the ascendance of experimental philosophy from the 1660s.

Imre Lakatos' philosophical and scientific papers are published here in two volumes. Volume I brings together his very influential but scattered papers on the philosophy of the physical sciences, and includes one important unpublished essay on the effect of Newton's scientific achievement. Volume 2 presents his work on the philosophy of mathematics (much of it unpublished), together with some critical essays on contemporary philosophers of science and some famous polemical writings on political and educational issues.

Natural philosophy encompassed all natural phenomena of the physical world. It sought to discover the physical causes of all natural effects and was little concerned with mathematics. By contrast, the exact mathematical sciences were narrowly confined to various computations that did not involve physical causes, functioning totally independently of natural philosophy. Although this began slowly to change in the late Middle Ages, a much more thoroughgoing union of natural philosophy and mathematics occurred in the seventeenth century and thereby made the (...) Scientific Revolution possible. The title of Isaac Newton's great work, The Mathematical Principles of Natural Philosophy, perfectly reflects the new relationship. Natural philosophy became the 'Great Mother of the Sciences', which by the nineteenth century had nourished the manifold chemical, physical, and biological sciences to maturity, thus enabling them to leave the 'Great Mother' and emerge as the multiplicity of independent sciences we know today.
