En comparant les deux auteurs que cite Malebranche Iorsqu'il met en place sa doctrine de la vision en Dieu, on montre ce qu'il y a d'irréconciliable avec l'exemplarisme augustinien et thomasien. Aucun de ces deux auteurs n'avait dit en effet que nous voyons les corps en Dieu. De plus, l'influence de l'exemplarisme sur la noétique thomasienne suppose l'efficacité des causes secondes que la notion de cause occasionnelle récuse. La vision en Dieu est pourtant une tentative pour appliquer l'exemplarisme à la nouvelle conception de la matière et de la connaissance, en vue de conserver une doctrine plus classique de la création que ne l'était celle de Descartes. This paper compares the affirmation of Malebranche that we see everything in God with the medieval doctrine of exemplarism, particularly the one of augustine and Aquinas that he cites. None of these authors has said that we see the bodies in God. Moreover, the role of exemplarism in the noetic of Aquinas implies the efficacity of the secondary cause that the notion of occasionnai cause in Malebranche refutes. The doctrine of vision in God is nevertheless an attempt to apply exemplarism to the new conception of matter and knowledge which purpose is to preserve a more classical conception of creation that the one of Descartes.

In this paper, I argue that commentators have missed a significant clue given by Descartes in coming to understand his 'ontological' proof for the existence of God. In both the analytic and synthetic presentations of the proof throughout his writings, Descartes notes that the proof works 'in the same way' as a particular geometrical proof. I explore the significance of such a parallel, and conclude that Descartes could not have intended readers to think that the argument consists of some kind of intuition. I argue that for Descartes the attribute of existence is a 'second-order' attribute that is demonstrated to belong to the idea of God on the basis of 'first-order' attributes. The proof, properly understood, is in fact a demonstration. Having brought to light the geometrical parallels between the ontological and geometrical proofs, we have new evidence to resolve the 'intuition versus demonstration' controversy that has characterized much of the discussion of Descartes's ontological argument.

Abstract:  Contrary to received opinion, Descartes' view on the merits of the ontological proof may actually agree with that of Thomas Aquinas, whose rejection of the a priori existence proof has stocked the armories of anti-Anselmians ever since. In a rarely noted passage of the First Replies, Descartes claims not to differ in any respect from Thomas on the proof, a claim that gains sense in light of recent work on the Fifth Meditation. That work in turn reveals a well-founded, if surprising, understanding of the Cartesian proof and of Cartesianism's true relation to Thomism.

The French philosopher and theologian Nicolas Malebranche was one of the most important thinkers of the early modern period. A bold and unorthodox thinker, he tried to synthesize the new philosophy of Descartes with religious Platonism. This is the first collection of essays to address Malebranche's thought comprehensively and systematically. There are chapters devoted to Malebranche's metaphysics, his doctrine of the soul, his epistemology, the celebrated debate with Arnauld, his philosophical method, his occasionalism and theory of causality, his philosophical theology, his account of freedom, his moral philosophy, and his intellectual legacy.

In this paper we argue that the primary issue in Descartes’ Principles of Philosophy, Part II, articles 1-40, is the problem of individuating bodies. We demonstrate that Descartes departs from the traditional quest for a principle of individuation, moving to a different strategy with the more modest aim of constructing bodies adequate to the needs of his cosmology. In doing this he meets with a series of difficulties, and this is precisely the challenge that Newton took up. We show that Descartes’ questions and his strategy influenced not only Newton’s account of physical bodies, but also the structure of his mechanics.

Nicolas Malebranche is one of the most important philosophers of the 17th Century after Descartes. A pioneer of Rationalism, he was one of the first to champion and to further Cartesian ideas. Andrew Pyle places Malebranche's work in the context of Descartes and other philosophers, and also in its relation to ideas about faith and reason. He examines the entirety of Malebranche's writings, including the famous The Search After Truth , which was admired and criticized by both Leibniz and Locke. Pyle presents an integrated account of Malebranche's central theses, occasionalism and 'vision in God', before exploring and assessing Malebranche's contribution to debates on physics and biology, and his views on the soul, self-knowledge, grace, and the freedom of the will. This penetrating and wide-ranging study will be of interest to not only philosophers, but also to historians of science and philosophy, theologians, and students of the Enlightenment or 17th Century thought.

: Malebranche famously objects to Descartes' argument that the nature of the mind is better known than the nature of body as follows: if we had an idea of the mind's nature we would know the possible range of modes of the mind, including the sensory modes, but we do not know those modes and thus can't have an idea of the mind's nature. I argue that Malebranche's objections are readily answerable from within the Cartesian system. This argument involves examining the status of sensations in Descartes, innate ideas, and Malebranche's occasionalism.

The rich connections between metaphysics and natural philosophy in the early modern period have been widely acknowledged and productively mined, thanks in no small part to the work of Margaret Wilson, whose book, Descartes, served as an inspirational example for a generation of scholars. The task of this paper is to investigate one particular such connection, namely, the relation between occasionalist metaphysics and strict mechanism. My focus will be on the work of Nicholas Malebranche, the most influential Cartesian philosopher after Descartes himself. I begin with two crucial facts about Malebranche’s philosophy: (1) Malebranche was an occasionalist, that is, he held that God was the only true cause, that all modifications of bodies and of minds can be produced by God alone. (2) Malebranche adhered firmly to strict mechanism. By strict mechanism, I mean the view, found most prominently in Descartes and in Boyle’s more ideological writings, that the qualities of bodies are exhausted by a very short list (size, shape, motion, and perhaps solidity) and that, most importantly, bodies interact only at contact by impact. Another way of describing this “contact action” requirement is as the thesis that the only fundamental laws of physics are laws of inertial motion and laws of the communication of motion at impact.
