In his concise Cartesian textbook entitled _Physiology_ (1641) Henricus Regius went beyond what could be found in Descartes’ published writings. There is no doubt that Regius completed some of its contents himself, but Descartes generously shared his (unpublished) views with him as well. This article investigates this tension on two specific points that relate to the function of the pineal gland and the animal spirits. First, did Descartes change his mind between the _Treatise on Man_ and the _Passions_ regarding the last step of sensory perception in the brain? It is argued he did not. Second, does the soul move or determine the movement of the animal spirits via the pineal gland? It is argued the soul determines the movement.

Dans le cadre de nos recherches sur la correspondance de Descartes, nous avons découvert une lettre inédite du philosophe. La lettre, qui se trouve à la Staatsbibliothek zu Berlin, Preußischer Kulturbesitz, est addressee à Joachim de Wicquefort, datée de Leyde, le 2 octobre 1640. Dans sa lettre Descartes réclame, par l' intermédiaire de Wicquefort, la traduction latine de ses Meteores, qui avait été remis au professeur de philosophie d'Amsterdam, Caspar Barlaeus. Elle précède de trois jours la lettre, déjà connue, à Wicquefort sur le même sujet. L'importance de notre lettre est qu'elle confirme certaines hypothèses concernant l'édition latine du Discours, et le projet abandonné de la publication des objections faites au Discours et aux Essais et des réponses du philosophe.

In lieu of an abstract, here is a brief excerpt of the content:Descartes’s Lettre Apologétique aux Magistrats d’Utrecht:New Facts and MaterialsErik-Jan BosThe lettre apologétique aux magistrats d’utrecht was Descartes’s final effort to obtain satisfaction from the Municipality or ‘Vroedschap’ of Utrecht. In 1643 the Vroedschap had condemned Descartes’s Epistola ad Dinetum and Epistola ad Voetium in defence of Descartes’s opponent Gisbertus Voetius (1589–1676), professor of Theology at the University of Utrecht.1 In the Lettre apologétique Descartes requests the Utrecht Vroedschap to revoke their condemnation, to clear his name and to reconsider Voetius’s position.The Lettre apologétique receives little attention in modern editions of Descartes’s works. Adam and Tannery give both the French and the Latin version of the Lettre apologétique, but with scanty annotation and an unsatisfactory introduction (AT VIIIB).2 The only other edition of the Lettre apologétique is provided by Verbeek, in La Querelle d’Utrecht (1988), but it does not go beyond Adam and Tannery’s edition.3In 1992, however, Verbeek noted that the Lettre apologétique could not possibly date from 1645, which was the hypothesis of Adam and Tannery and still is the [End Page 415] prevailing view.4 This raises once again the question of the real date of the Lettre apologétique as well as of the history of the text. In this essay I propose a new date and a new account of the history of the text. I also draw attention to the Dutch version of the Lettre apologétique, which Descartes sent to the Utrecht Vroedschap in 1648, but first I will give a short survey of Descartes’s dispute with Voetius.1. THE UTRECHT QUARRELIf we are to believe Descartes in his Lettre apologétique, it was Voetius who started the quarrel in 1639 by accusing him of atheism in several disputations, an accusation to which Voetius stuck throughout the affair.5 Descartes admits he is not mentioned in the writings of the Utrecht theologian, but “[Voetius] counted among the characteristics of atheism everything he knew to be commonly attributed to me” (AT VIIIB 205). A few years later, in 1641, Voetius called the adherents of the New Philosophy atheists outright. In a reaction to Descartes’s champion in Utrecht, the professor of medicine Henricus Regius (1598–1679), who claimed Aristotelian philosophy to be of no use for explaining natural phenomena, Voetius warned that the rejection of traditional philosophy would lead to scepticism and eventually to disbelief. With Descartes’s help Regius furnished a reply, in which he insinuated that it was, instead, the obscurities in Neo-Scholastic thought which led to the denial of God.6 This answer elicited protest from the University Senate. On the Senate’s request the Utrecht Vroedschap confiscated Regius’s book and forbade the teaching of any ideas deviating from Aristotle. Regius having been silenced, Descartes proceeded in a personal capacity. He vehemently attacked Voetius, first in the Epistola adDinetum, then in an elaborate work, the Epistola ad Voetium. The latter was meant as a response to a book opposing Descartes published by the professor of philosophy in Groningen, Martin Schoock (1614–1669), a friend of Voetius.7 The Vroedschap then condemned the works and Descartes became [End Page 416] subject to criminal charges. Thanks to his influential friends, Descartes was never put on trial, yet he felt that his reputation had been badly damaged. Several times he demanded satisfaction from the Utrecht Vroedschap, but to no avail.Until recently, the texts published in the polemic between Descartes and Voetius were considered to be of no more than anecdotal value in Descartes’s biography. It is only for the past decade that their philosophical relevance has been recognized. From what seemed to be unpromising material, various scholars have presented new perspectives on both Voetius and Descartes.8 They have shown that the objections raised by Voetius and Schoock against Cartesian philosophy prove to be more fundamental and to the point than formerly believed. Although Descartes never made a serious attempt on his own to meet Voetius on philosophical grounds, his writings are interesting because he brings forward theoretical positions which before he had...
