One of the most pressing philosophical problems in early modern Europe concerned how the soul and body could form a unity, or, as many understood it, how these two substances could work together. It was widely believed that there were three (and only three) hypotheses regarding the union of soul and body: (1) physical influence, (2) occasionalism, and (3) pre-established harmony. However, in 1763, a fourth hypothesis was put forward by the French thinker André-Pierre Le Guay de Prémontval (1716–1764). Prémontval’s (...) hypothesis, given the grand name of “psychocracy” (i.e., the dominion or the rule of the soul), held that there was a real influence between soul and body, but that this was an immaterial kind of influence as opposed to the physical kind that had been entertained heretofore. Prémontval’s hypothesis is the focus of this paper. I shall begin by sketching out the details of Prémontval’s hypothesis (Section 1), then proceed to consider its claims to constitute a true fourth hypothesis distinct from the other three (Section 2), before closing by briefly considering two objections and the responses either that Prémontval himself made or that may be made on his behalf (Section 3).

The usual reading of Descartes' “anthropological” perspective classifies it as a radical dualism with a distinction between two substances, mind and body, which experience major interaction difficulties. Through a contextualization of Descartes' physiological and psychological thought as well as through a less fragmented reading of his work, we intend to review this traditional interpretation, thereby showing its distorted character. When we pay attention to passion, a new Descartes’ image as a sort of phenomenal monism appears, which is markedly different from (...) the legendary image typically associated with him, even today.

This paper examines Aquinas's theory of dualist mental causation, that is, his theory of how human beings can efficiently cause changes in their bodies in virtue of two non-physical mental states of theirs, specifically an act of the intellect and an act of the will. It is first shown that Aquinas's hylomorphism does not lie at the heart of this theory. Rather, a relation that he calls “contact of power” (tactus virtutis) does. The remainder of the paper then investigates the (...) nature of this relation. Since Aquinas discusses key marks of it by contrasting it with physical contact, the paper focuses on this contrast. It is argued that, for Aquinas, the human soul stands in a relation of contact of power to the body or, more precisely, a certain part of the body when it causes a change in it and is holenmerically co-located with it.

While Descartes’s Passions of the Soul has been taken to hold a place in the history to human physiology, until recently philosophers have neglected the work. In this research summary, I set Descartes’s last published work in context and then sketch out its philosophical significance. From it, we gain further insight into Descartes’s solution to the Mind--Body Problem -- that is, to the problem of the ontological status of the mind--body union in a human being, to the nature of body--mind (...) causation, and to the way body-caused thoughts represent the world. In addition, the work contains Descartes’s developed ethics, in his account of virtue and of the passion of générosité in particular. Through his taxonomy of the passions and the account of their regulation, we also learn more about his moral psychology. (shrink)

At the heart of Descartes’s theory of cognition is the act of perceiving an idea. However, it remains unclear what precisely an idea is, what the act of perceiving ideas amounts to, and how that act contributes to the formation of cognition under Descartes’s view. In this paper, I provide an account of perceiving ideas that clarifies Descartes’s notion of an idea and explains the fundamental role that the perceiving of ideas occupies in his theory of cognition. At the end (...) of the paper, I will address an issue that arises regarding the objective reality of ideas and the unity of mind. (shrink)

Descartes endorses the two prima facie inconsistent claims that sensory ideas are innate and caused in us by bodies. Most scholars believe that Claims A and B can be reconciled by appealing to the notion of occasional or triggering causation. I claim that this notion does not solve the theoretical problems it is introduced to solve and it generates additional difficulties. I argue that these difficulties result from conflating two questions that need to be kept distinct while inquiring about the (...) origin of ideas: the psychological question of the mechanisms by which we acquire ideas and the metaphysical question of how the content of these ideas is determined. I conclude by proposing a new way of reconciling Descartes's Claims A and B in light of this distinction. On my account, Descartes's very views on innateness explain why bodily states must be causes of sensory ideas. (shrink)

It is a common view that Descartes' causal principle is to be understood in light of a similarity condition that accounts for how finite causes contribute to an explanation of their effects. This paper challenges this common view and offers a sui generis reading of Descartes' views on causation that has also the advantage of solving the two exegetical issues of whether Descartes thought of the body-to-mind relation in occasionalist or causal terms and of whether Descartes regarded sensory ideas innate (...) or caused by bodies.

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)

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)

Consider the distinctive qualitative property grass visually appears to have when it visually appears to be green. This property is an example of what I call sensuous color. Whereas early modern mechanists typically argue that bodies are not sensuously colored, Margaret Cavendish (1623–73) disagrees. In cases of veridical perception, she holds that grass is green in precisely the way it visually appears to be. In defense of her realist approach to sensuous colors, Cavendish argues that (i) it is impossible to (...) conceive of colorless bodies, (ii) the very possibility of color experience requires that bodies are sensuously colored, and (iii) the attribution of sensuous colors to bodies provides the best explanation of color constancy. Although some passages might suggest that Cavendish endorses a reductive account of sensuous color, according to which sensuous color reduces to a body's microscopic surface texture (or some other mechanistically respectable property), I argue that she accepts a nonreductive account, on which sensuous color is not thus reducible.

Mary Astell (1666-1731) relies on a Cartesian account of the self to argue that both men and women are essentially thinking things and, hence, that both should perfect their minds or intellects. This account of the self might seem to ignore the inescapable fact that we have bodies. I argue that Astell accommodates the self’s embodiment along three dimensions. First, she tempers her sharp distinction between mind and body by insisting on their union. Second, she argues that the mind-body union (...) is good, at least when the body obeys the mind. Third, though Astell identifies the self with the mind, she identifies the person with the combination of mind and body. (shrink)
