In this essay I address the debate between Pierre Chanet and Marin Cureau de La Chambre on animal instinct, analyzing and connecting it to the question of the relationship between God and secondary causes. While Chanet considers instinctive actions as the result of direct intervention by God, that would conduct his creatures beyond their natural limits, Cureau places them in the cognitive structure that God has given to the animals, doing of instinctive actions natural actions in the strict sense. Starting from that, Cureau can introduce a bizarre analogy between animal’s innate capability to act in the environment beyond any previous experience and the innate knowledge of angels. This comparison is strongly criticized by Chanet and probably persuades Cureau to change his presentation of the soul in his late masterpiece, "Le Systéme de l’âme". My conclusion is that both Chanet’s and Cureau’s accounts for animal instinct are functional to an anthropocentric metaphysics that keeps the human soul as an intellective, individual and separable substance; but they also provide - especially with Cureau - a good example of a compromise between hylomorphism, dualism and mechanism.

The problem of Divine Ideas is one of the most consequential in the entire history of Western Thought, and effects of the Medieval debate on exempla-rism can still be found in Early Modern and Modern metaphysics. Speaking of the Middle Ages, such a topic provides a vivid example of the prominent role played by Platonism in the tradition of the Schools in the 13th and the 14th century, often associated with the sole authority of Aristotle. Among the different traditions animating the Schools at this stage, the Franciscan is surely one of the most sensitive to this topic, both because of the relevance attributed to Augustine as a fundamental authority of the Order, and of the turning point brought about by Bonaventure. These are just a few of the reasons why the collective volume Divine Ideas in Franciscan Thought (XIIIth-XIVth Century), edited by Jacopo Francesco Falà and Irene Zavattero, should be welcomed. The book is published within the series of medieval studies Flumen Sapientiae, directed by Irene Zavattero. It collects chapters in English and Italian, all dealing with Medieval Franciscan thought in the 13th to the 14th centuries, authored by a team made up of experienced and younger scholars. Five precious textual appendixes in Latin (Olivi, Trabibus, Novocastro, Caracciolus, Mayronis) accompany the essays, providing very useful study materials.

This chapter focuses on the question of the specific truth granted to the human intellect’s concepts qua concepts (simplex apprehensio), as it is presented and discussed in Sebastião do Couto’s commentary on On Interpretation, included in his general commentary on Aristotle’s Dialectics (1606), the final volume of the famous and influential Cursus Conimbricensis (1592–1606). Such a topic finds it roots in a large medieval debate that runs through many authors and especially Augustine, Aquinas, Scotus, Durandus, and Ockham, reaching in the Jesuit early modern context, with Pedro da Fonseca and Francisco Suárez, a complete and eclectic account that paved the way for the modern understanding of “mind.”

The article introduces Marin Cureau de La Chambre’s theory of light, focusing especially on the treatise Le Lumière (1657). Specifically, the anti-Cartesian and anti-mechanistic side of Cureau’s work is stressed, reconstructing its account of the “essential” nature of light, linking it to the Franciscan and the Platonic tradition and focusing on the peculiar use of the notion of “extensio formalis.” Additionally, Cureau’s theory of color and his theories on irradiance and light’s movement is presented. Finally, the article illustrates Cureau’s qualitative explanation of refraction and reflection, reconstructing his role in the genesis of Fermat’s ‘principle of least time.’

This paper deals with Suárez's theory of extension and continuous quantity, as it is discussed in the Metaphysical Disputations and as a possible source for Descartes's concept of res extensa. In a first part of the paper, I analyse Suárez' account of divisibility and extension in a comparison with the Dominicans', Scotus and Fonseca's, and Ockham's. In the light of this analysis, Suárez's most original contribution seems being the claim that material composites have integral parts 'entitatively' extended (partem extra partem) independently from categorial quantity. Such a theory allows Suárez to merge the Dominicans', the Scotists' and the Ockhamists' account, as the integral parts fund the internal but pre-quantitative divisibility of body, which is the source of quantity. In a second part of the paper, I deal with the reception of Suárez’s theory (especially in Rubio, Arriaga, Araujo, Eustachius and Abra de Raçonis), as well as with Descartes’ concept of res extensa. I conclude that Suárez’s account has been mainly criticized by the seventeenth Century Aristotelianism, as well as by Descartes. Despite that, Suárez’s idea of non-quantitatively extended parts had an interesting reception and effect in the debate, and especially in the (dominant) Scotistic context.

The article examines Marin Cureau de La Chambre's Système de l'âme (1664), highlighting the role played in the work by the tradition of Italian Renaissance naturalism. La Chambre profoundly criticizes the very concept of 'passion of the soul', attacking the Aristotelian doctrine of the possible intellect but, contemporarily, also the direct interaction between body and mind presupposed by Descartes in Les passions de l'âme. The solution adopted by Cureau is based on the doctrine of intermediate substances, which allows him to resume Ficino's model, reconciling it with Descartes' intellec-tualist dualism and integrating the latter with a panpsychism of Campanellian brand.

In this essay, I address Descartes’ medical thought, starting from the years of Le Monde and focus- ing especially on the “ontological” explanation of the dropsy in the Sixth Meditation. I especially consider Descartes’ attempt to ‘reform’ physiology according to the universal methodology of geometrical reasoning, as well as with the importance given by Descartes’ epistemology to the re- lationship between medicine and the mind-body union. The possibility of a coherent explanation of all the embodied phenomena, including illness and passions is, in fact, a strategic opportunity to show the existence of an inner regularity in God’s Creation and so, to reconnect any ‘practical’ order (including medicine) to His essence. This leads Descartes to implicitly face the problem of the monstrous births, retracing what he could find in Toledo’s and Conimbricenses’ Commentaria.
