The Modeling of Nature provides an excellent introduction to the fundamentals of natural philosophy, psychology, logic, and epistemology.

v. 1. Medieval and early classical science.--v. 2. Classical and contemporary science.

A summary of basics for student and seminarian.

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.

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)

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)

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 use of mathematical models to support decision making is proliferating in both the public and private sectors. Advances in computer technology and greater opportunities to learn the appropriate techniques are extending modeling capabilities to more and more people. As powerful decision aids, models can be both beneficial or harmful. At present, few safeguards exist to prevent model builders or users from deliberately, carelessly, or recklessly manipulating data to further their own ends. Perhaps more importantly, few people understand or appreciate (...) that harm can be caused when builders or users fail to recognize the values and assumptions on which a model is based or fail to take into account all the groups who would be affected by a model's results. This volume provides a setting for a dialogue about ethics and shows the need to continue and define a vocabulary for exploring ethical concerns. It will become increasingly important for model builders and users to have a clear and strong code of ethics to guide them in making the ethical decisions they surely will have to face. (shrink)

In his review of my Prelude to Galileo, Ernan McMullin rejects my emendation of Pierre Duhem's “continuity thesis” wherein I develop the case for a pronounced medieval-scholastic influence on Galileo's science based on parallels between Galileo's early Latin compositions and lectures given by contemporary Jesuits at the Collegio Romano. He does so on two grounds: that the evidence of derivation I provide, using textual parallels, is so strong that it refutes the claim for any intellectual influence, being a better instance (...) of mindless copying than one of personal appropriation; and that, in any event, the logical structure of the argument which I attribute to Galileo's mature work is not that of demonstration ex suppositione as understood by Aquinas, and so the example I provide of Galileo's use of suppositio “does not link him in any significant way to the specifically Thomist tradition of natural science”. An adequate reply to this critique would require the introduction of more historical evidence than would be appropriate for the pages of this journal. A few remarks, however, may be in order concerning such evidence which bears directly on McMullin's first ground, and concerning the implications of this evidence for contemporary philosophy of science, which bear on his second.
