We apply Benacerraf’s distinction between mathematical ontology and mathematical practice to examine contrasting interpretations of infinitesimal mathematics of the seventeenth and eighteenth century, in the work of Bos, Ferraro, Laugwitz, and others. We detect Weierstrass’s ghost behind some of the received historiography on Euler’s infinitesimal mathematics, as when Ferraro proposes to understand Euler in terms of a Weierstrassian notion of limit and Fraser declares classical analysis to be a “primary point of reference for understanding the eighteenth-century theories.” Meanwhile, scholars like (...) Bos and Laugwitz seek to explore Eulerian methodology, practice, and procedures in a way more faithful to Euler’s own. Euler’s use of infinite integers and the associated infinite products are analyzed in the context of his infinite product decomposition for the sine function. Euler’s principle of cancellation is compared to the Leibnizian transcendental law of homogeneity. The Leibnizian law of continuity similarly finds echoes in Euler. We argue that Ferraro’s assumption that Euler worked with a classical notion of quantity is symptomatic of a post-Weierstrassian placement of Euler in the Archimedean track for the development of analysis, as well as a blurring of the distinction between the dual tracks noted by Bos. Interpreting Euler in an Archimedean conceptual framework obscures important aspects of Euler’s work. Such a framework is profitably replaced by a syntactically more versatile modern infinitesimal framework that provides better proxies for his inferential moves. (shrink)

Cauchy's sum theorem is a prototype of what is today a basic result on the convergence of a series of functions in undergraduate analysis. We seek to interpret Cauchy’s proof, and discuss the related epistemological questions involved in comparing distinct interpretive paradigms. Cauchy’s proof is often interpreted in the modern framework of a Weierstrassian paradigm. We analyze Cauchy’s proof closely and show that it finds closer proxies in a different modern framework.

Thomas Aquinas produced a voluminous body of work on moral theory, and much of that work is on virtue, particularly the status and value of the virtues as principles of virtuous acts, and the way in which a moral life can be organized around them schematically. Thomas Osborne presents Aquinas's account of virtue in its historical, philosophical and theological contexts, to show the reader what Aquinas himself wished to teach about virtue. His discussion makes the complexities of Aquinas's (...) moral thought accessible to readers despite the differences between Thomas's texts themselves, and the distance between our background assumptions and his. The book will be valuable for scholars and students in ethics, medieval philosophy, and theology. (shrink)

Thomas Aquinas, John Duns Scotus, and William of Ockham disagree over how and whether virtues are specified by their objects. For Thomas, habits and acts are specified by their formal objects. For instance, the object of theft is something that belongs to someone else, and more particularly theft is distinct from robbery because theft is the open taking of another’s good, whereas robbery is open and violent. A habit such as a virtue or a vice shares or takes (...) the act’s object. For Scotus, although the same virtue or act cannot have objects which differ formally, different virtues and acts can have an object which is identical according to its formal ratio, in the way that the different theological virtues might even formally have God as their object. Ockham accepts Scotus’s view that charity and hope are two kinds of love, we will see how, unlike Scotus, he argues that these theological virtues differ on account of their immediate complex objects. The disagreement between these three figures raises important difficulties concerning what it even means to be a formal object. (shrink)

Contemporary Philosophy in Focus offers a series of introductory volumes to many of the dominant philosophical thinkers of the current age. Thomas Kuhn, the author of The Structure of Scientific Revolutions, is probably the best-known and most influential historian and philosopher of science of the last 25 years, and has become something of a cultural icon. His concepts of paradigm, paradigm change and incommensurability have changed the way we think about science. This volume offers an introduction to Kuhn's life (...) and work and then considers the implications of Kuhn's work for philosophy, cognitive psychology, social studies of science and feminism. The volume is more than a retrospective on Kuhn, exploring future developments of cognitive and information services along Kuhnian lines. Outside of philosophy the volume will be of particular interest to professionals and students in cognitive science, history of science, science studies and cultural studies. (shrink)

The past few years have seen a revival of interest in Thomas Reid's philosophy. His moral theory has been studied by D. D. Raphael (The Moral Sense) and his entire philosophical position by S. A. Grave (The Scottish Philosophy of Common Sense). Prior to both, A. D. Woozley gave us the first modern reprint of Reid's Essays on the Intellectual Powers of Man - in fact the first edition of any work by Reid to appear in print since the (...) Philosophical Works was edited in the nineteenth century by Sir William Hamilton. But Reid's aesthetic philosophy has not received its due. Woozley, in abridging the Essays, omitted the whole final essay, "On Taste," which is the only extended work on aesthetic theory that Reid ever published. Raphael, being interested primarily in Reid's moral theory, understand ably, treated aesthetics only as it was related to morality. And Grave, although he did present a short and very cogent resume of Reid's aes thetic position, obviously found himself drawn to other elements of Reid's philosophy. There are, of course, some accounts of Reid's aes thetic theory to be found in the various studies of eighteenth-century British aesthetics and criticism. None, however, appears to me to do any kind of justice to the philosophical questions which Reid treats in his aesthetics and philosophy of art. (shrink)

Although Thomas, Scotus, and Ockham are all broadly Aristotelian, their different Aristotelian accounts reflect underlying disagreements in these three areas. These trends may represent a shift from an earlier to a later medieval intellectual culture, but they also reflect views that continued to exist in different schools. Thomists continued to exist alongside Scotists through the end of the eighteenth century, and Ockham’s views had a more varied but continued influence through the modern period. The different views of Thomas, (...) Scotus, and Ockham are not only in themselves plausible attempts at understanding human action, but they formed the background to late medieval and early modern descriptions of human action.

INTRODUCTION Although the writings of Thomas Reid are very fertile and interesting, his life is biographically barren in comparison to such seventeenth - and ...

The Essays on the Active Powers of Man was Thomas Reid's last major work. It was conceived as part of one large work, intended as a final synoptic statement of his philosophy. The first and larger part was published three years earlier as Essays on the Intellectual Powers of Man. These two works are united by Reid's basic philosophy of common sense, which sets out native principles by which the mind operates in both its intellectual and active aspects. The (...) Active Powers shows how these principles are involved in volition, action, and the ability to judge morally. Reid gives an original twist to a libertarian and realist tradition that was prominently represented in eighteenth-century British thought by such thinkers as Samuel Clarke and Richard Price.

Thomas Reid saw the three subjects of logic, rhetoric, and the fine arts as closely cohering aspects of one endeavor that he called the culture of the mind. This was a topic on which Reid lectured for many years in Glasgow, and this volume presents as near a reconstruction of these lectures as is now possible. Though virtually unknown today, this material in fact relates closely to Reid's published works and in particular to the late Essays on the Intellectual (...) Powers of Man and Essays on the Active Powers of Man. When composing these works, Reid drew primarily on his lectures on "pneumatology," which presented a theory of the mental powers, broadly conceived. These lectures were basic to the course on the culture of the mind that explained the cultivation of the mental powers. Although the Essays also included some elements from the material on the culture of the mind, the bulk of the latter was left in manuscript form, and Alexander Broadie's edition restores this important extension of Reid's overall work. In addition, this volume continues the attractive combination of manuscript material and published work, in this case Reid's important and well-known essay on Aristotle's logic. This text was corrupted in earlier editions of Reid's works and is now restored to the state in which Reid left it. This volume underscores Reid's great and growing significance, viewed both as a historical figure and as a philosopher. At the same time, it is of great interdisciplinary importance. While the material emerges directly from the core of Reid's philosophy, as now understood, it will appeal widely to people in literary, cultural, historical, and communications studies. In this regard, the present volume is a true fruit of the Scottish Enlightenment. (shrink)

Thomas Jefferson is among the most important and controversial of American political thinkers: his influence (libertarian, democratic, participatory, and agrarian-republican) is still felt today. A prolific writer, Jefferson left 18,000 letters, Notes on the State of Virginia, an Autobiography, and numerous other papers. Joyce Appleby and Terence Ball have selected the most important of these for presentation in the Cambridge Texts series: Jefferson's views on topics such as revolution, self-government, the role of women and African-American and Native Americans emerge (...) to give a fascinating insight into a man who owned slaves, yet advocated the abolition of slavery. The texts are supported by a concise introduction, suggestions for further reading and short biographies of key figures, all providing invaluable assistance to the student encountering the breadth and richness of Jefferson's thought for the first time.

Is it possible for an individual that has gone out of being to come back into being again? The English Aristotelian, Thomas White, argued that it is not. Thomas Hobbes disagreed, and used the case of the Ship of Theseus to argue that individuals that have gone out of being may come back into being again. This paper provides the first systematic account of their arguments. It is doubtful that Hobbes has a consistent case against White. Still his (...) criticism may have prompted White to clarify his views on identity over time in his later work. (shrink)

The distinction between Thomas and Scotus on threefold referral is superficially similar in that both use the same terminology of actual, virtual, and habitual referral. For Scotus, an act is virtually referred to the ultimate end through an agent’s somehow explicitly thinking about the end and some sort of causal connection between the virtually intended act and the actually intended act. For Thomas, someone with charity virtually refers his acts to God as the ultimate end not because the (...) act has been caused by an actually intended act, but because the act is the kind of act that can be referred to God as the ultimate end, and the agent himself is ordered to that end. Similarly, For Scotus a good act might be only habitually referred to God because the agent does not think about him. For Thomas, the fact that someone with charity would only habitually order an act to God can only be explained by a defect in the act. The act lacks a virtual order to God because it is the kind of act which cannot be so ordered. The difference between Scotus and Thomas on this issue expresses a fundamental difference over the relationship between individual acts and the ultimate end. For Thomas, every good act is orderable and this order is made virtual merely by an agent’s possession of charity. The virtual order requires an actually ordered act only to the extent that the possession of charity does. For Scotus, the order requires some sort of additional act by the agent. (shrink)

Although Thomas Aquinas and John Duns Scotus disagree over how the acquired moral virtues are connected, the nature of their disagreement is difficult to determine. They and their contemporaries reject the Stoic understanding of this connection, according to which someone either possesses all the acquired moral virtues in the highest degree or none of these virtues at all. Both Thomas and Scotus hold that someone might generally perform just actions and yet be unchaste. Moreover, although they interpret Aristotle (...) differently, both accept the Aristotelian view that a good person is free from vice and that his virtues are connected through prudence. They agree that the just but unchaste person is not a good person. But a major difference between the two is in their understanding of the way in which the virtues are so connected and their manner of describing that imperfect or partial prudence which is possessed by such a person who does not have each of the major virtues.

The work of Thomas White represents a systematic attempt to combine the best of the new science of the seventeenth century with the best of Aristotelian tradition. This attempt earned him the criticism of Hobbes and the praise of Leibniz, but today, most of his attempts to navigate between traditions remain to be explored in detail. This paper does so for his ontology of accidents. It argues that his criticism of accidents in the category of location as entities over (...) and above substances was likely aimed at Francisco Suárez, and shows how White’s worries about the analysis of location were linked with his broader cosmological views. White rejects real qualities, but holds that the quantity of a substance is somehow distinct from its bearer. This reveals a common ground with some of his scholastic interlocutors, but lays bare a deep disagreement with thinkers like Descartes on the nature of matter. (shrink)

Thomas Reid is now recognized as one of the towering figures of the Enlightenment. Best known for his published writings on epistemology and moral theory, he was also an accomplished mathematician and natural philosopher, as an earlier volume of his manuscripts edited by Paul Wood for the Edinburgh Reid Edition, Thomas Reid on the Animate Creation, has shown. The Correspondence of Thomas Reid collects all of the known letters to and from Reid in a fully annotated form. (...) Letters already published by Sir William Hamilton and others have been reedited, and roughly half of the letters included appear in print for the first time. Writing in 1802, Reid's disciple and biographer Dugald Stewart doubted that Reid's correspondence &"would be generally interesting.&" This collection proves otherwise, for the letters illuminate virtually every aspect of Reid's life and career and, in some instances, provide us with invaluable evidence about activities otherwise undocumented in his manuscripts or published works. Through his correspondence we can trace Reid's relations with contemporaries such as David Hume and his colleagues at both King's College, Aberdeen, and the University of Glasgow, as well as his engagement with the most controversial philosophical, scientific, and political issues of his day. If anything, the letters assembled here serve as the starting point for understanding Reid and his place in the Enlightenment. (shrink)

The great medieval philosopher Thomas Aquinas was Dominican regent master in theology at the University of Paris, where he presided over a series of questions - academic debates - on ethical topics. This volume offers translations of disputed questions on the nature of virtues in general, the fundamental or 'cardinal' virtues of practical wisdom, justice, courage, and temperateness, the divinely bestowed virtues of hope and charity, and the practical question of how, when and why one should rebuke a 'brother' (...) for wrongdoing. The introduction explains how Aquinas's theory of virtue fits into his ethics as a whole, and it illuminates Aquinas's views by explaining the institutional and intellectual context in which these disputed questions were debated.

During the last fifteen years some theologians during have supported their understanding of how unbelievers might be saved by appealing to Thomas Aquinas and the development of his thought in by sixteenth-century Dominicans at Salamanca. These Salamancan Dominicans applied Thomas’ thought in the context of the New World’s discovery. These recent theologians attribute two claims to this tradition: first, that not every unbeliever is guilty of unbelief, and second, that unbelievers can perform good acts which in some strong (...) manner enable them to receive grace. I shall argue that although the first claim about the culpability of unbelief is held by the Thomist tradition, it has no historical or logical connection to the salvation of unbelievers. I shall argue that the second claim was not held by the tradition and that the contemporary misinterpretation results from a confusion over the relationship between moral goodness and merit. Whereas the first claim is historically accurate but irrelevant to the contemporary views for which it is invoked, the second claim is historically false if attributed to Thomas Aquinas or the Dominican tradition at Salamanca.
