Rene Descartes

the dream had touched the split-off problem of his feeling and the religious problem of evil… they already sketch, in a nutshell, the actual problem of the man of our time, the heir to that epoch of eighteenth-century rationalism, at the dawn of which Descartes stands

Von Franz argues that Descartes’s dreams reveal the split-off feeling problem at the root of Western rationalism, making him a symptomatic figure for modern psychological one-sidedness.

He puzzled over the function of the pineal gland, which he conjectured to be the ‘connecting place’ of body and soul… rather an atrophying of the life of feeling.

Von Franz identifies Descartes’s preoccupation with the pineal gland as symptomatic of his inability to integrate feeling, diagnosing an atrophy of the affective dimension rather than any repressed sexuality.

The physiological operations that we call mind are derived from the structural and functional ensemble rather than from the brain alone: mental phenomena can be fully understood only in the context of an organism’s interacting in an environment.

Damasio directly counters Cartesian dualism by grounding mind in the organism-environment ensemble, presenting the body-brain unity as the antidote to Descartes’s error.

Descartes tends to be looked at through epistemological lenses, or else, following the post-structuralists, as the founder of a new subjectivist ‘conception of Being’… such approaches are tone deaf to the literary and philosophical genres in which Descartes conveyed his ‘first philosophy’.

Sharpe and Ure argue that both epistemological and post-structuralist readings of Descartes miss the spiritual-exercise and autobiographical dimensions of his philosophical practice.

Ure and Sharpe contend that dominant readings of Descartes fail to engage the lived, genre-specific practice embedded in the Discourse and Meditations.

The unconscious inhibition that hindered Descartes from investigating this complex of problems more deeply must, in the final analysis, have been his adherence to the Christian définition of evil as a mere privatio boni.

Von Franz diagnoses Descartes’s theological commitment to evil as privatio boni as the unconscious barrier that prevented deeper psychological and metaphysical exploration.

Descartes’s Meditations is among the most influential texts in the history of Western philosophy. Many thinkers have challenged or rejected his thought, some of them almost totally, but his rigorous questioning of traditional certainties is at the source of most subsequent philosophical developments.

The editorial introduction to the Meditations establishes Descartes’s central importance by noting that the very scope of subsequent criticism testifies to the foundational power of his philosophy.

In producing a philosophy that made the existence of God and the immateriality of the soul certain, Descartes was not simply laying foundations for science: he could claim, as he does in his letter to the Sorbonne, and quite sincerely, to be

Descartes’s distinction between mind and body was perceived by contemporaries, not as reassuring or uplifting, but as downright strange. The physical dimension of thought and experience was not something scholastic philosophers and theologians needed to have revealed by audacious and heterodox innovators.

The commentary argues that the mind-body distinction was historically received as strange rather than liberating, correcting retrospective assumptions about Cartesian dualism’s cultural valence.

Descartes is quite naturally in doubt as to whether this wind is the spirit of God or the spirit of Satan… Descartes’s uncertainty concerning the moral significance of the storm may be compared with the doubt experienced by Saint Ignatius of Loyola.

Von Franz reads Descartes’s dream imagery of wind and ambiguous spiritual agency as a classical psychic expression of the tension between divine and demonic forces in the individuation process.

Descartes also hoped that science would make us ‘the masters and possessors of nature’… The soul is the ‘res cogitans’.

Von Franz connects Descartes’s dream-state enthusiasm for mastery over nature with the res cogitans formula, linking the metaphysical programme to the will to dominate that his unconscious was simultaneously subverting.

Descartes’s prefatory letter to the Sorbonne announces the two foundational demonstrations — God’s existence and the mind-body distinction — that structure the entire Meditations project.

In the Sixth Meditation Descartes articulates the functional union of mind and body through the mechanics of sensation, presenting divine providence as the ground of psychosomatic coordination.

the strengthening of rationality probably requires that greater consideration be given to the vulnerability of the world within.

Damasio draws a practical implication from his critique of Cartesian reason, arguing that genuine rationality must be grounded in attentiveness to the inner emotional world that Descartes’s dualism discounted.

if I can clearly and distinctly understand one thing without another, this is sufficient for me to be certain that the one is distinct from the other, since they can at least be produced separately by God.

This passage from the Sixth Meditation states the epistemological criterion — clear and distinct conceivability — that Descartes deploys to establish the real distinction between mind and body.

Bourdin urges that Descartes’s doubt ought logically to extend further: that the dream-hypothesis destabilizes not only sense-perceptions but supposedly clear and distinct perceptions of intellectual truths.

The commentary notes Bourdin’s sharpest objection — that Cartesian doubt, if consistently applied, undermines clear and distinct intellectual intuition as well as sense-perception.

His objections and Descartes’s replies hardly indicate a meeting of minds, but they are philosophically interesting for Hobbes’s attempt to substitute a materialist ontology and method for Descartes’s own approach.

The commentary contextualises Hobbes’s Third Objections as a programmatic materialist counter to Cartesian dualism, illustrating the immediate seventeenth-century reception of the Meditations.

Descartes also occupied himself with the meaning of his dream and its ‘divine character’… he says: ‘I thought I already knew enough of their worth not to be liable to be deceived any more, whether by the promises of an Alchemist, or by the predictions of an Astrologer, or by the impostures of a Magician.’

Von Franz’s footnotes document Descartes’s own engagement with the meaning of his prophetic dreams alongside his explicit repudiation of alchemical and astrological knowledge.

it is sufficient for us Christians to believe by faith that the human soul does not perish with the body and that God exists, yet it seems certain that unbelievers cannot be convinced of the truth of religion… unless these first two truths are proved to them by natural reason.

Descartes’s letter to the Sorbonne frames the Meditations as an apologetic enterprise, making natural reason the foundation for persuading non-believers of God’s existence and the soul’s immortality.
