Descartes is always concerned about knowledge. However, the Galileo affair in 1633, the reactions to his Discourse on method, and later his need to reply to objections to his Meditations provoked crises in Descartes’s intellectual development the import of which has not been sufficiently recognized. These events are the major reasons why Descartes’s philosophical position concerning how we know and what we may know is radically different at the end of his life from what it was when he began. We (...) call this later position Descartes’s epistemic stance and contrast it with his earlier methodological, metaphysical realism. Yet Descartes’s epistemic views cannot be separated from other aspects of his work, for example, his views concerning God, causality, metaphysics, and the nature of science. A further meta-implication is that serious errors await any scholar who cites early Cartesian texts in support of late Cartesian positions, or who uses later texts in conjunction with early ones to support a reading of Descartes’s philosophy.Keywords: René Descartes; Nature; Motion; Method; Knowledge.

Between the years 1643 and 1649, Princess Elisabeth of Bohemia and René Descartes exchanged fifty-eight letters—thirty-two from Descartes and twenty-six from Elisabeth. Their correspondence contains the only known extant philosophical writings by Elisabeth, revealing her mastery of metaphysics, analytic geometry, and moral philosophy, as well as her keen interest in natural philosophy. The letters are essential reading for anyone interested in Descartes’s philosophy, in particular his account of the human being as a union of mind and body, as well as (...) his ethics. They also provide a unique insight into the character of their authors and the way ideas develop through intellectual collaboration. Philosophers have long been familiar with Descartes’s side of the correspondence. Now Elisabeth’s letters—never before available in translation in their entirety—emerge this volume, adding much-needed context and depth both to Descartes’s ideas and the legacy of the princess. Lisa Shapiro’s annotated edition—which also includes Elisabeth’s correspondence with the Quakers William Penn and Robert Barclay—will be heralded by students of philosophy, feminist theorists, and historians of the early modern period.

‘God needs no instruments to act,’ Malebranche writes in Search 6.2.3; “it suffices that He wills in order that a thing be, because it is a contradiction that He should will and that what He wills should not happen. Therefore, His power is His will”. After nearly identical language in Treatise 1.12, Malebranche writes that “[God's] wills are necessarily efficacious … His power differs not at all from His will”. God exercises His causal power, here, via His volitions; what He (...) causes depends not merely on the fact that He wills, but specifically on the content of His volitions, on “what He wills.” Yet despite the obviously key role the ordinary notion of volitional content plays for Malebranche, recent writers have paid surprisingly little attention either to it or its exegetical implications. I hope partly to rectify this situation here.The plan of this paper is this: to borrow current work in the philosophy of mind to sketch the notion of an incomplete volition, i.e. one whose content is ‘incomplete’ in a sense to be explained; to note that Malebranche accepts and uses something like this notion.

This paper is the first of a two-part reexamination of causation in Descartes's physics. Some scholars ? including Gary Hatfield and Daniel Garber ? take Descartes to be a `partial' Occasionalist, who thinks that God alone is the cause of all natural motion. Contra this interpretation, I agree with literature that links Descartes to the Thomistic theory of divine concurrence. This paper surveys this literature, and argues that it has failed to provide an interpretation of Descartes's view that both distinguishes (...) his position from that of his later, Occasionalist followers and is consistent with his broader metaphysical commitments. I provide an analysis that tries to address these problems with earlier `Concurentist' readings of Descartes. On my analysis, Occasionalism entails that created substances do not have intrinsic active causal powers. As I read him, Descartes thinks that bodies have active causal powers that are partly grounded in their intrinsic natures. But I argue ? pace a recent account by Tad Schmaltz ? that Descartes also thinks that God immediately causes all motion in the created world. On the picture that emerges, Descartes's position is both continuous with, and a subtle departure from, the Thomisitic theory of divine concurrence. (shrink)

Le présent ouvrage esquisse une histoire de la notion de causalité, telle qu'elle s'est problématisée à la jointure de la philosophie et de la science aux XVIIè et XVIIIè siècles. La philosophie a toujours pensé la rationalité scientifique à partir de l'idée d'un rapport causal. Toutefois, avec l'avènement de la science nouvelle, il se produit une profonde mutation dans la sémantique de la causalité. Cette remise en cause, d'abord imperceptible, devient explicite, chez Hume notamment. De fait, elle est à l'origine (...) des difficultés et des doutes que connaîtra par la suite la philosophie quant à la cohérence et à la validité de la notion de cause. (shrink)

My topic is God's activity in the ordinary course of nature. The precise mode of this activity has been the subject of prolonged debates within every major theistic intellectual tradition, though it is within the Catholic tradition that the discussion has been carried on with the most philosophical sophistication. The problem, in its simplest form, is this: Given the fundamental theistic tenet that God is the provident Lord of nature, the First Efficient Cause who creates the universe, sustains it in (...) being, and exists in all things by His essence, presence, and power,1 how exactly do the actions of secondary (i.e., created) causes fit in with God's own activity in the ordinary course of nature? Or, to put it a bit more neutrally, how exactly is God's own action as the First Cause in nature related to the causal activity, if any , of His creatures? (shrink)

It is well known that the French Cartesian Nicolas Malebranche (1638–1715) was both an occasionalist in metaphysics and a mechanist in physics. He consistently argued that God is the only true caus...

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. (shrink)
