In the _Meditations_ and related texts from the early 1640s, Descartes argues that the self can be correctly considered as either a mind or a human being, and that the self’s properties vary accordingly. For example, the self is simple considered as a mind, whereas the self is composite considered as a human being. Someone might object that it is unclear how merely considering the self in different ways blocks the conclusion that a single subject of predication—the self—is both simple (...) and composite, which is contradictory. In response to this objection, this paper develops a reading of Descartes’s various ways of considering the self. I argue that the best reading of Descartes’s qualified claims about the self, i.e., about the self _qua_ mind or the self qua human being, presupposes an account of the unqualified self, that is, of the self _simpliciter_. I argue that the self _simpliciter_ is not a mind, and that it is not a human being either. This result might suggest the pessimistic conclusion that Descartes’s view of the self is incoherent. To avoid this result, I introduce a new metaphysical account of the Cartesian self. On my view, the self is individuated by a unified mental life. The self is constituted by the beings that jointly produce this mental life, and derives its unity from it. (shrink)

Descartes argues that the mind and body are really distinct substances. He also insists that minds and bodies compose human beings. But how are mind and body united to compose a human? This question is crucial to understanding the place of human beings in Descartes’s ontology. Many scholars argue that Descartes has no solution to the unity problem, and they call into question the ontological status of mind-body composites. On some views, Cartesian humans are mere aggregates, like stacks of pancakes; (...) on other views, Descartes is not entitled to the view that humans exist at all. I argue that Descartes has a solution to the unity problem, and that he appropriates this solution from contemporaneous Jesuit discussions of soul-body unity—discussions that remain mostly unknown to contemporary scholars. The upshot is that Descartes has the metaphysical machinery to account for mind-body unity and doesn’t have to say that a human being is like a stack of pancakes. (shrink)
