This paper examines Descartes's third primary notion and the distinction between different kinds of knowledge based on different and mutually irreducible primary notions. It discusses the application of the notions of clearness and distinctness to the domain of knowledge based on that of mind-body union. It argues that the consequences of the distinctions Descartes is making with regard to our knowledge of the human mind and nature are rather different from those that have been attributed to Descartes due to the (...) influential Rylean picture of Cartesian mind-body dualism.

Throughout their life Ibn Sînâ and Descartes firmly believed that the soul or mind of a human being was essentially incorporeal. In his ‘On the Soul’ (De anima), the psychological part of his vast...

In this work I argue that Descartes was not a trialist by showing that the main tenets of trialist interpretations of Descartes's theory of substance are either not supported by the text or are not sufficient for establishing the trialist interpretation.

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 article analyses recent English publications in Cartesian studies that deal with two problems: the problem of the intrinsic coherence of Descartes’s doctrine of the real distinction and interaction between mind and body and the problem of the consistency of this doctrine with the causal principle formulated in the Third Meditation. The principle at issue is alternatively interpreted by different Cartesian scholars either as the Hierarchy Principle, that the cause should be at least as perfect as its effects, or the (...) Containment Principle, that the cause should contain all there is in its effects. The author argues that Descartes’s claim that it is inconceivable how things of different natures can interact does not conflict with the acknowledgement of interaction between things of different natures in the case of soul and body. The case is made that Cartesian mind-body interaction can agree with both the Hierarchy Principle and the Containment Principle, because the Principle is about total and efficient cause, whereas in the interaction, mental and brain states are only partial causes. In particular, in the case of the causality in the brain-to-mind direction, the mind is conditioned by brain states to form the corresponding specific ideas on the basis of its innate general ideas of movements, forms, colours, etc. Eventually, for Descartes, the most natural way to deal with worries about the possibility of mind-brain interaction is to rely on God’s omnipotence, which certainly enables Him to arrange for such interaction.

The author argues for the reductive interpretation of Descartes’ notion of the substantial union of soul and body, according to which the union is reduced to causal interactions. The opponents countered the reductive approach with the claims that Descartes (1) attributed sensations to the union rather than the soul; (2) held that the soul is the substantial form of the body; (3) identified some special conditions of the human body’s self-identity. In the article, the case is made that (a) these (...) claims lack clear textual evidence: if their context is properly considered, Descartes’ corresponding statements are consistent with the reductive interpretation; (b) they do not give proper weight to other Descartes’ statements (in particular, his numerous unambiguous statements that sensations are the soul’s states). The author argues that the reductive interpretation is consistent with other Descartes’ statements to which its opponents appeal - that sensations arise from the union of mind and body and that the causal interactions between the soul and the body are explained with the reference to their union. The consistency is achieved if we interpret these statements in the sense that the enduring union between a soul and a body is an ontological prerequisite and, hence, an explanation, of all interactions between the soul and the body and their effects (such as sensations): these interactions and effects would not take place without the union between this particular soul and this particular body. Such explanation is similar to the explanation of certain natural events by the laws of nature: just as the gist of a law of nature can be reduced to a set of causal dispositions, so the content of the notion of the union can be reduced to the emergence and maintenance of a set of causal dispositions between a certain soul and a certain body.

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.

‘God needs no instruments to act,’ Malebranche writes in Search 6.2.3; “it suffices that He wills in order that a thing be, because it is a contradiction that He should will and that what He wills should not happen. Therefore, His power is His will”. After nearly identical language in Treatise 1.12, Malebranche writes that “[God's] wills are necessarily efficacious … His power differs not at all from His will”. God exercises His causal power, here, via His volitions; what He (...) causes depends not merely on the fact that He wills, but specifically on the content of His volitions, on “what He wills.” Yet despite the obviously key role the ordinary notion of volitional content plays for Malebranche, recent writers have paid surprisingly little attention either to it or its exegetical implications. I hope partly to rectify this situation here.The plan of this paper is this: to borrow current work in the philosophy of mind to sketch the notion of an incomplete volition, i.e. one whose content is ‘incomplete’ in a sense to be explained; to note that Malebranche accepts and uses something like this notion.

As a tenacious and rigorous reader of the Cartesian corpus, Merleau-Ponty payed special attention to its ambiguities. On the one hand, the intellectualism of the Cartesian theory of perception (Dioptrique) goes along with a mechanistic physiology (Traité de l’Homme) and also with the substantial dualism of the first Méditations Métaphysiques. On the other, Descartes always insisted on hylomorphism, composition, permixtio and even substantial union. Thereby, the human body becomes endowed with such peculiar properties as its inner binding, indivisibility and a (...) biological self-interest, instilling a certain teleology into a part of extension.

Resumen En este artículo se examina el Darwinismo Neural en su explicación de la evolución de la conciencia humana, contrastando su metodología con la utilizada por Richard Lewontin, Richard Levins y Steven Rose, quienes han hecho importantes aportaciones en el estudio de los sistemas vivos desde un punto de vista dialéctico. Concluimos que la explicación interaccionista de la evolución de la conciencia planteada en el DN, supera muchas de las deficiencias del determinismo biológico; sin embargo, al compartir algunos lineamientos con (...) el cartesianismo, mantiene un carácter a-histórico insuficiente para la explicación de la conciencia humana. Finalmente, proponemos la adopción de una teoría explicativa de la conciencia humana que considere las relaciones existentes en ella, no sólo como interacciones sino también como interpenetraciones ontogénicas y filogenéticas.This article examines Neural Darwinism proposed as an explanation of evolution of human consciousness. His methodology is contrasted with that used by Richard Lewontin, Richard Levins, and Steven Rose, who made important contributions to the study of living systems from a dialectical point of view. We conclude that the interactionist explanation of the evolution of conscience put forward in ND overcomes many of the deficiencies proper to biological determinism. However, as ND also shares many of the foundations of the Cartesian approach, it maintains a non-historical character, insufficient for the account of human consciousness. We suggest the adoption of an alternative theory, able to fully explain human conscience which must consider the whole of existing relations in it, and, instead of merely considering them as interactions, they have to be observed as dialectical interpenetrations.

The aim of this thesis is to investigate the role that the imagination plays in the later philosophy of René Descartes. The thesis will look at two related questions: the status of the imagination as a mode of thought dependent on the body; the role of the imagination in object-perception. Throughout, the traditional view of Descartes as a Cartesian Dualist is rejected and a more holistic approach is taken towards the relationship between mind and body, in which Descartes’ claims that (...) the two make up a “substantial union” are taken seriously. Part One deals with the relationship between mind and body. I argue that Cartesian Dualism cannot account for the faculties of sensation and imagination, because they have a corporeal basis. However, the ‘union of mind and body’, Descartes’ device for explaining their interaction, can. I end Part One by identifying a problem with the paradigm case of mind-body interaction, object-perception. To determine the object of an idea there needs to be a mechanism to marry the two ingredients of perception: the innate ideas of geometry in the intellect, and ‘adventitious’ ideas of the object delivered by the senses. Otherwise we have no explanation for how the essentially ‘inward-looking’ intellect can apply its ideas to the essentially passive sensations. Part Two focuses on the imagination and the question of object-perception raised in Part One. I argue against the largely-held view in the secondary literature that, with the advent of the cogito, the imagination’s cognitive profile declined sharply. I argue that, in fact, the corporeal basis of the imagination places it beautifully to bridge the gap in object-perception, and that this is part of its role in all Descartes’ discussions on the topic. The other, related, role of the imagination is to conjure fictions and hypotheses, suiting it for scientific and epistemological endeavours. The fact that the imagination is not tied to what is present to the senses, even though it receives its original content from them, means that it can manipulate ideas of corporeal things; including the innate notions of extension, shape and motion so key to gaining a clear and distinct idea of matter.
