In the third intermède of Le Malade Imaginaire, Molière imagines a sort of medical convention in which "the wisest experts and professors of Medicine" examine whether a bachelor candidate can be deemed to enter the medical profession. As the first question in this examination, the "Chief physician" asks, "What is the cause and reason [causam et rationem] why opium induces sleep?" The candidate answers without the least hesitation: "Because it contains a sleeping virtue [virtus dormitiva], whose nature is to put (...) the senses to sleep." The answer is followed by a jubilant reaction by the choir: "Good, good, good, he answers well, he is worthy of entering in our wise gild."1The scene is intended to be a... (shrink)

In this book Han Thomas Adriaenssen offers the first comparative exploration of the sceptical reception of representationalism in medieval and early modern philosophy. Descartes is traditionally credited with inaugurating a new kind of scepticism by saying that the direct objects of perception are images in the mind, not external objects, but Adriaenssen shows that as early as the thirteenth century, critics had already found similar problems in Aquinas's theory of representation. He charts the attempts of philosophers in both periods to (...) grapple with these problems, and shows how in order to address the challenges of scepticism and representation, modern philosophers in the wake of Descartes often breathed new life into old ideas, remoulding them in ways that we are just beginning to understand. His book will be valuable for historians interested in the medieval background to early modern thought, and to medievalists looking at continuity with the early modern period. -/- . (shrink)

As far as treatments of causation are concerned, the pre-Kantian 18th century German context has long been dismissed as a period of uniform and unrepentant Leibnizian dogmatism. While there is no question that discussions of issues relating to causation in this period inevitably took Leibniz as their point of departure, it is certainly not the case that the resulting positions were in most cases dogmatically, or in some cases even recognizably, Leibnizian. Instead, German theorists explored a range of positions regarding (...) the nature of causal powers, the appropriate systems to explain the observed agreement between the states of substances, and the ground of free actions, or so I will argue in this chapter. Focusing on these three issues, I will here sketch the development of the debates relating to causation and trace the evolution of positions among the philosophers within the so-called Leibnizian-Wolffian philosophy as well as among its many opponents.

Of Malebranche's many famous doctrines, his “Vision in God” (VIG) surely ranks among the most interesting. Inspired by Augustine and Descartes, he argues for it vigorously and gives it a prominent place in his system of thought. And although it won no converts it did win many critics, who, in criticizing, were compelled to clarify their own theories of cognition. Thus VIG is of interest for its own sake, for its role in Malebranche's philosophy, and for its general influence in (...) the early modern period. (shrink)

"The French philosopher Nicolas Malebranche popularized the doctrine of occasionalism in the late seventeenth century. Occasionalism is the thesis that God alone is the true cause of everything that happens in the world, and created substances are merely "occasional causes." This doctrine was originally developed in medieval Islamic theology, and was widely rejected in the works of Christian authors in medieval Europe. Yet despite its heterodoxy, occasionalism was revived starting in the 1660s by French and Dutch followers of the philosophy (...) of René Descartes. Since the 1970s, there has been a growing body of literature on Malebranche and occasionalism. There has also been new work on the Cartesian occasionalists before Malebranche - including Arnold Geulincx, Geraud de Cordemoy and Louis de la Forge. But to date there has not been a systematic, book-length study of the reasoning that led Cartesian thinkers to adopt occasionalism, and the relationship of their arguments to Descartes' own views. This book expands on recent scholarship, to provide the first comprehensive account of seventeenth century occasionalism. Part I contrasts occasionalism with a theory of divine providence developed by Thomas Aquinas, in response to medieval occasionalists; it shows that Descartes' philosophy is compatible with Aquinas' theory, on which God "concurs" in all the actions of created beings. Part 2 reconstructs the arguments of Cartesians - such as Cordemoy and a Forge - who used Cartesian physics to argue for occasionalism. Finally, it shows how Malebranche's case for occasionalism combines philosophical theology with Cartesian metaphysics and mechanistic science"--. (shrink)

Johann Christoph Sturm’s natural philosophy, with which Leibniz engages in “De ipsa natura”, as well as Petrus van Musschenbroek’s epistemology, constitute important steps in the process of the speciation of physics. In this case, speciation is understood as the process through which the explanation of natural phenomena via empirical regularities comes to define the whole domain of the newly established niche of physics, to the exclusion both of teleology and efficient causality.

There is a general sense that the philosophy of Descartes was a dominant force in early modern thought. Since the work in the nineteenth century of French historians of Cartesian philosophy, however, there has been no fully contextualized comparative examination of the various receptions of Descartes in different portions of early modern Europe. This study addresses the need for a more current understanding of these receptions by considering the different constructions of Descartes's thought that emerged in the Calvinist United Provinces (...) and Catholic France, the two main centers for early modern Cartesianism, during the period dating from the last decades of his life to the century or so following his death in 1650. It turns out that we must speak not of a single early modern Cartesianism rigidly defined in terms of Descartes's own authorial intentions, but rather of a loose collection of early modern Cartesianisms that involve a range of different positions on various sets of issues. Though more or less rooted in Descartes's somewhat open-ended views, these Cartesianisms evolved in different ways over time in response to different intellectual and social pressures. Chapters of this study are devoted to: the early modern Catholic and Calvinist condemnations of Descartes and the incompatible Cartesian responses to these; conflicting attitudes among early modern Cartesians toward ancient thought and modernity; competing early modern attempts to combine Descartes's views with those of Augustine; the different occasionalist accounts of causation within early modern Cartesianism; and the impact of various forms of early modern Cartesianism on both Dutch medicine and French physics.
