RésuméDans sa présentation récente de la «dialectique de la création» dans la philosophie du XVIIe siècle, Thomas Lennon suggère que les hypothèses de Descartes concernant la causalité conduisent à un dilemme : Descartes doit accepter soit une certaine sorte d'émanationnisme panthéiste, soit l'émergence de la réalité ex. nihilo. Dans cet article, je défends en détail cette suggestion de Lennon. Au cœur de la question se trouve la notion cartesienne de la possession éminente. Si cette notion est interprétée dans ce que (...) j'appelle un sens «réaliste», ainsi que Descartes lui-mêmesemble l'avoir fait, alors il n'y a pas moyen d'éviter l'émanationnisme panthéiste. Si la possession est interprétée dans ce que j'appelle un sens «réductionniste», comme l'ont fait la plupart des commentateurs récents, alors le principe causal fundamental de Descartes se révèle soit arbitraire soit trivial.

In his recent survey of the “dialectic of creation” in seventeenth-century philosophy, Thomas Lennon has suggested that Descartes’s assumptions about causality encourage a kind of “pantheistic emanationism”. Lennon notes that Descartes regularly invokes the principle that there is nothing in the effect which was not previously present, either formally or eminently, in the cause. Descartes also believes that God is the continuous, total, and efficient cause of everything. From these assumptions it should follow that everything that exists in the created (...) world is previously present in God. Indeed, Descartes embraces the emanationist doctrine explicitly when, at the end of his replies to the Second Set of Objections, he arranges the arguments of the Meditations in “geometrical fashion.” The demonstration of Proposition III includes a sub-proof of the proposition that “he who preserves me has within himself, either formally or eminently, whatever is in me”. Since God preserves the entire universe, it follows that everything is in him, either formally or eminently. While far from the radical Spinozistic view that God and the world are identical, the notion that everything in creation is also in God would seem to have its own unwelcome theological consequences, at least from a Cartesian point of view. In particular, it implies that extension, and hence divisibility, are in God. But, as Descartes himself cautions, “being divisible is an imperfection” and so completely foreign to God. (shrink)

After a brief analysis of the nature of occasional causation, distinguishing it from both efficient causation and the doctrine of occasionalism, it is argued that this model of causation informs Descartes' account of the generation of sensory ideas in the mind. It is further argued that, consequently, Descartes is not an occasionalist on this matter.

Descartes maintained that sensations of color and the like misrepresent the material world in normal circumstances. Some prominent scholars have argued that, to explain this Cartesian view, we must attribute to Descartes a causal account of sensory representation. I contend that neither the arguments motivating this reading nor the textual evidence offered in its support is sufficient to justify such attribution. Both textual and theoretical reasons point in the direction of an (at least partial) internalist account of Descartes' views on (...) sensory representation. (shrink)
