This article considers Descartes's famous claim that mind and body are distinct substances from the unusual perspective of Nicolas Malebranche. In particular, it focuses on Malebranche's argument that since Cartesians feel compelled to support such a claim by appealing to their clear idea of body, they must lack access to a clear idea of soul. The main conclusion is that while such an argument does not apply directly to Descartes's discussion in the "Meditations" of mind- body distinctness, this discussion nonetheless renders Descartes vulnerable to Malebranche's central charge that the nature of body is for Cartesians better known than the nature of the soul

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.

This book is a systematic study of Descartes' theory of causation and its relation to the medieval and early modern scholastic philosophy that provides its proper historical context. The argument presented here is that even though Descartes offered a dualistic ontology that differs radically from what we find in scholasticism, his views on causation were profoundly influenced by scholastic thought on this issue. This influence is evident not only in his affirmation in the Meditations of the abstract scholastic axioms that a cause must contain the reality of its effects and that conservation does not differ in reality from creation, but also in the details of the accounts of body-body interaction in his physics, of mind-body interaction in his psychology, and of the causation that he took to be involved in free human action. In contrast to those who have read Descartes as endorsing the "occasionalist" conclusion that God is the only real cause, a central thesis of this study is that he accepted what in the context of scholastic debates regarding causation is the antipode of occasionalism, namely, the view that creatures rather than God are the causal source of natural change. What emerges from the defense of this interpretation of Descartes is a new understanding of his contribution to modern thought on causation.
