Nicolas Malebranche was the first Cartesian philosopher to challenge Descartes’ claim that we are capable of possessing a clear and distinct understanding of the soul's nature. Other Cartesians, including Clauberg, La Forge, and Cordemoy, accepted without question the conclusion of the Second Meditation that the nature of the soul is better known than is the nature of body. After presenting an overview of Malebranche's argument, this note turns to the Cartesian philosopher Pierre-Sylvain Régis. Régis, like the Cartesians before Malebranche, sides with Descartes in this debate over the question of whether we can have knowledge of our soul's nature, but unlike his predecessors, he provides an original argument defending his position. This argument is, I argue, a direct response to the argument Malebranche had used in his case against Descartes.

While there has been a resurgence in Malebranche scholarship in the anglophone world over the last twenty years, most of it has focused on Malebranche’s theory of ideas, and little attention has been paid to his philosophy of mind. Schmaltz’s book thus comes as a welcome addition to the Malebranche literature; that he has given us such a well-researched and carefully argued study is even more welcome. The focus of this work is Malebranche’s split with Descartes on the question of our knowledge of the nature of the mind; the book concentrates specifically on Malebranche’s rejection of the claim that we know the nature of the mind better than we know the nature of body. Schmaltz maintains that Malebranche’s arguments for his position are, for the most part, successful against the Cartesians who opposed him, though he claims—and this is perhaps the central claim of the book—that “Malebranche took his negative thesis concerning our knowledge of the soul to involve not so much a rejection of Cartesianism as an internal correction of it”. While acknowledging that Augustine was “the primary inspiration for [Malebranche’s] view of the ideas that are the objects of perception”, Schmaltz’s interpretation of Malebranche’s theory of the soul “presents it as fundamentally Cartesian”. According to Schmaltz, not only is Malebranche closer to Descartes in this regard than is generally thought, he is closer to him than are many other Cartesians. Part 1 of the book examines Malebranche’s position that while we have certain knowledge of the soul’s existence, we have only confused knowledge of its nature. Part 2 focuses on Arnauld’s objection that if in fact we had no clear idea of the soul, we could not, despite Malebranche’s claims to the contrary, know anything of its immortality, spirituality, or freedom.

Descartes’s First Meditation employs a series of arguments designed to generate the worry that the senses might not provide sufficient evidence to justify one’staking as certain one’s beliefs about the way the world is. As the meditator considers what principle describes the conditions under which it is possible to attain certain knowledge, one after another doubt-generating device is ushered in, until at last he finds himself like someone caught in a whirlpool, able neither to stand firm nor to swim out. In this paper, I examine one of those devices, namely, what is often referred to as the Madness Argument. In particular, I want to discuss its relation to the Dream Argument and its function in the Meditations as a whole. My position stands in contrast to the interpretations of Anthony Kenny, Margaret Wilson, Michael Williams, and, more recently, Janet Broughton and Catherine Wilson.

In my essay I look at the specifics of the dispute between the Scottish metaphysician Andrew Baxter and the mathematician Colin MacLaurin in an attempt to identify the source or sources of their contradictory, yet in both cases Newtonian, positions regarding occasionalism. After some general introductory remarks about each thinker, I examine the metaphysical implications that Baxter sees as following from Newton's concept of vis inertiæ. Following this, I look at MacLaurin's commitment to the role of sense experience in natural philosophy. Finally, I discuss the different passages from Newton's Opticks on which the two thinkers focus.

The answer which Joseph Almog gives to the question which serves as the title of his recent book What Am I? (subtitled: Descartes and the Mind-Body Problem) is based upon his interpretation of (1) and objection to Descartes' argument for the distinction of the mind and the body raised by Antoine Arnauld, as well as Descartes' response to it, and (2) Descartes' letters of 9 February 1645 to Denis Mesland. I will argue that both of these interpretations are incorrect, and as such do not support the conclusions which Almog claims to draw from them. The answer, then to the question of what I am which Almog provides is, I believe, not one Descartes would have held, nor one which his writings support. (Published Online October 13 2005).
