Contrary to what many interpretations claim, according to Bayle faith does not completely eliminate reason. It intervenes to reveal factual truths that can only be known through revelation (for example, that God allowed Adam and Eve to sin). To these factual truths can be applied a rational principle (an axiomatic and evident one, according to Bayle, which he calls a "common notion"), namely, that "what God does is well done." God allowed sin, so we must think it was justified, even (...) if we don't understand why. This approach is what I call, cum grano salis, Pierre Bayle's theodicy. (shrink)

James of Viterbio is one of the rare medieval authors to sustain a thoroughly innatist philosophy. He borrows from Simplicius the notion of idoneitas (aptitude, predisposition) so as to ground a cognition theory in which external things are not the efficient and formal causes of mental acts. A predisposition has the characteristic of being halfway between potentiality and actuality. Therefore, the subject that has predispositions does not need to be acted upon by another thing to actualize them. External things only (...) “incline” the mind to make use of a stock of cognitive schemes. Consequently, in order to avoid an infinite regress James must adopt innatism. Following the lead of late Neoplatonism, he goes as far as including, not only conceptual schemes, but also perceptual schemes among the inbuilt stock. As a result, James’s theory, while it echoes certain preoccupations and themes that are common in the thirteenth century, proves to be one of a kind. (shrink)

pierre bayle’s treatise on tolerance is a landmark in the birth of the modern mind. Written shortly before Locke’s Letter on Toleration, it advocates full toleration of all religious beliefs, not by reduction to the lowest common denominator, but rather because of the moral evilness of persecutions and forced conversions.However, many commentators believe that there is a flaw in Bayle’s theory: the so-called “conscientious persecutor aporia.”1 In order to show the wickedness of persecution, Bayle holds up conscience as an apparently (...) absolute, inviolable principle. As we shall see, the primary ethical imperative is to obey the “dictates” of one’s conscience, that is, to do what conscience shows us to.. (shrink)

The medieval notion of instrumental cause is not limited to what we call today “instruments” or “tools.” It extends way beyond the realm of technology and includes natural entities, for instance, the accidents by which a substance acts on another substance, sensible species in the air acting on a visual faculty, sacraments, bodily organs, and sometimes creatures with respect to God’s action. In all these cases, instrumental causes, like secondary causes in general, are subordinated to a principal cause and contribute (...) to its action and effects. However, the manner in which they do so makes them different from regular secondary causes, and the specifics are not easy to pinpoint. At the occasion of discussions about creation ex nihilo and sacraments, John Duns Scotus challenges Thomas Aquinas’s theory of instrumental causality. Whereas Aquinas does not strongly distinguish between artifacts and natural agents, and postulates a complex superposition of layers of causation, Scotus offers a novel view that clearly separates artificial instrumentality and natural instrumentality, and in both cases explains causation with great economy. Scotus’s in-depth discussion has far-reaching implications. It completely transforms the understanding of instrumental causality in general. (shrink)

The problem of the intensification and remission of qualities was a crux for philosophical, theological, and scientific thought in the Middle Ages. It was raised in Antiquity with this remark of Aristotle: some qualities, as accidental beings, admit the more and the less. Admitting more and less is not a trivial property, since it belongs neither to every category of being, nor to every quality. Rather it applies only to states and dispositions such as virtue, to affections of bodies such (...) as heat and sweetness, and to affections of soul such as anger. However, the property of admitting more and less was a matter of importance for the qualitative physics that had reigned up to about the time of Descartes, a physics which was concerned with concepts such as heat, coldness, lightness, heaviness, and so on.

I examine Bayle's infamous statement that Christian mysteries are not only "above" human reason, but are "against" it. I put it back in the context of 16th-17th century Reformed thought. I then discuss the relation between reason and faith according to Bayle.

La solution de Thomas d’Aquin au problème de l’intensification des qualités souffre d’une certaine instabilité et, dans la génération suivante, a été disloquée par les différentes contraintes qu’elle tentait de concilier. Cet article explore les réponses apportées par Gilles de Rome, Godefroid de Fontaines, Pierre d’Auvergne et Thomas de Sutton. Introduite par Godefroid, mais développée par Sutton, la notion de mode va jouer un rôle très important. La solution de Sutton, particulièrement, invite à une comparaison avec la théorie des modes (...) intrinsèques chez Duns Scot. (shrink)

Pierre Bayle shows that, in order to avoid devastating objections, materialism should postulate that the property of thinking does not emerge from certain material combinations but is present in matter from the start and everywhere—a hypothesis recently revived and labelled “panpsychism”. There are reasons for entertaining the idea that Bayle actually considers this enhanced materialism to be tenable, as it might use the same line of defence that Bayle outlined for Stratonism. However, this would lead to a view similar to (...) Locke’s superaddition theory, and I contend that such cannot be Bayle’s position because he embraces the Cartesian principle that each substance has only one principal attribute. This makes untenable, in his eyes, any system that conjoins thought with matter in the same simple substance. By contrast, this makes clear which kinds of metaphysics and epistemology panpsychists need to adopt to defend their view. (shrink)

Bringing together two aspects of Thomas Aquinas's thought that have been studied separately: his theory of God's concurrence and his theory of instrumental causality, I show how he uses the latter (which I discuss first) to clarify the Proclusian principle that the first cause has a greater influence on an effect than the proximate causes. Thanks to this theory, Aquinas accounts for the fact that it is God who confers existence to every new being that is produced by natural processes, (...) without however negating the agency of secondary, created causes.

This paper explores the origins of the term "causa sine qua non" used by Durand de Saint-Pourçain to describe the role of material things in knowledge. I show that its technical meaning comes from the Stoics and was transmitted to the Middle Ages by Boethius' commentary on Cicero's Topics. The expression "sine qua non" here does not have the ordinary and restricted meaning of "indispensable", "necessary condition", which can also apply to direct, per se causes of an effect. In the (...) present context, sine qua non causes do not act on the effect in question, either as concomitant, secondary, or instrumental causes, or as remote causes. They act only on that which hinders the actualization of a potentiality, in order to remove that obstacle. For example, the removal of a support that prevented something from falling does not act on that thing, nor does it add anything to its tendency to fall; it simply enables that thing to exercise its own actualization. Similarly, in cognitive processes, external things do not impose anything on the soul, but simply give it the opportunity to actualize its faculties of its own accord. I situate Durand's use of this form of causality in the context of late 13th/early 14th century theories of cognition, among several other attempts to find an alternative theory to the standard Aristotelian model and to maintain the pure activity of the soul with respect to the body.

In this paper, I examine the problem of Bayle's skepticism. I show that he is not a wholesale skeptic. Rather, he thinks that reason is plagued by internal conflicts. But its principles, which clash with each other, can be adopted separately from each other. It is often what we have to do when dealing with metaphysical problems. This also entails that reason is not to be rejected as a whole when it happens to be contradicted by faith; only some of (...) its principles have to be denied, and solely in that case. Further, Bayle believes that we possess absolute certainly in our knowledge of ethical principles. I show how this is compatible with his relativism in other domains by putting back his contention in the context of Reformed thought. (shrink)

I first explain the scholastic (Scotist) thesis on the independence of essences Bayle alludes to in the passage of the Continuation des Pensée Diverses where he presents the Stratonicians' and the Chinese philosophers' retorsion. Then, I show that this retorsion applies to the argument of the existence of God based on "aseity", but not to the occasionalist argument based on the "quod nescis" principle. I conclude that materialism (the "Stratonician hypothesis") cannot be, for Bayle, a satisfying system.

This volume is a welcome addition to early modern scholarship, providing a source of reflection on the connection between cognition theory and causation theory. The collection's great merit is exploiting this cognition-causation connection to provide a new avenue for historical research that is at the same time philosophically significant.Several of the essays advance our understanding of key figures by using this connection to settle longstanding interpretive disputes. For instance, in "Descartes on the Causal Structure of...

La conception malebranchiste de la liberté est originale. Malebranche ne croit pas en une liberté d’indifférence absolue, c'est-à-dire en une capacité d’opérer un choix indépendamment de toute motivation. Il ne croit pas non plus que nous puissions indifféremment choisir entre deux motivations de force inégale : au moment où on se détermine, le bien le plus grand (du moins selon l’apparence) l’emporte. La liberté réside seulement dans le fait que l’on n’est pas obligé de se déterminer : nous pouvons toujours (...) suspendre notre consentement. Cette conception est exposée à des objections que Pierre Bayle a formulées et qui tentent de la mettre en contradiction avec d’autres thèses de Malebranche : son occasionalisme, sa théorie de la création continuée, l’obscurité de l’âme à elle-même, sa théologie des voies de l’action divine. Nous discuterons ces objections et verrons si Malebranche est en mesure de leur résister. (shrink)

An important step in In Pierre Bayle’s defense of religious tolerance is to refute St Augustine’s claim that heretics who refuse to convert to the true faith do so out of ill will. This claim legitimizes, for Augustine and his followers, the application of temporal sanctions to those heretics, in order to offset their wicked inclination and restore their free will. To counter this view, Bayle uses the theological notions of invincible ignorance and dutiful erroneous conscience, elaborated during the Middle (...) Ages. However, these notions had a very restricted scope, which needed to be extended to so-called heretical beliefs. I show how two early modern scholastics, the Jesuits Gabriel Vázquez and Rodrigo Arriaga, have prepared this evolution and have paved the way for Bayle's denunciation any form of coercion in religious matters.

On the question of the intensio/remissio formarum, Giles, while sharing Thomas Aquinas’s view’s main tenets, develops a very different theory - in fact, a theory that is unique, and deeply “aegidian”: the increase or decrease does not take place in the essence of a qualitative form, but only in its esse, in function of the disposition of the subject that receives this form. Giles’s position, however, may be threatened by a risk of infinite regress in the conditions that explain the (...) receptivity of a subject. He successfully addresses this issue, and, within the framework of Aristotelian physics, offers a very original response: qualitative changes in bodies are ultimately based, via condensation and rarefaction, on the spatial positions of their material parts.

Due to his innatist theory, James of Viterbo brings original answers to a number of late-thirteenth century questions concerning cognition. While he maintains a certain distinction between the soul and its faculties, and among these faculties, he rejects the Aristotelian distinction between agent and patient intellects. Thanks to its predispositions to knowing, the mind is able to be an agent for itself. Correlatively, James rejects the usual conception of abstraction. Neither does the intellect act on the phantasms, nor the phantasms (...) on the intellect. The intellect simply actualizes a conceptual scheme at the occasion of adequate sensory representations. Since the innate predispositions are the intrinsic principles of cognitive acts, James maintains with Giles of Rome the notion of intelligible species. But he agrees with Godfrey of Fontaines that an act of intellection is nothing else than the fully actualized species itself. He also concedes to Henry of Ghent that the form of an intelligible object need not be ontologically received in the intellect, but can just have an “objective” presence. Finally, thanks again to his theory of predispositions, he has an easy solution to the vexed problems of the knowledge of substance essences and of the self. (shrink)

The problem of the limitations of or conditions for God's power was one of the most fruitful topics in medieval discussions. While debating it, medieval thinkers came to redefine the concept of the "possible." William of Auxerre's disputed questions offer an example of critical reexamination of Aristotle's conception of possibility. Parallel to the account of William's views on the topic, the article provides (from a formal point of view, so to speak) an analysis of the sequence and formulation of the (...) questions he raises, in an attempt to propose a method for reading these frequently disconcerting texts.

Certains penseurs médiévaux jugeaient la philosophie incapable de juger et d'interpréter la parole révélée donc supérieure. Pour d'autres, elle gardait son prestige antique et pouvait les mener à la perfection et à la félicité. Ces contributions étudient non pas la philosophie du Moyen âge dans son ensemble, ce qui n'est pas possible, mais des personnalités particulières, dont des théologiens.

According to the Dominican Thomas of Sutton (ca. 1250–1315), the reception of intelligible species in the potential intellect is in every point similar to the actualization of forms in matter, which means that the potential intellect remains completely passive through the whole process of concept acquisition. However, Sutton adds that when the intelligible species are stored in the memory and aggregate in logically organized clusters, thus becoming intellectual habitus, they have a way of being that is not found in material (...) things, namely, incomplete actuality. Without being properly speaking efficient causes of mental processes, they spontaneously tend to emerge by themselves into the light of awareness—even though other elements (other intelligible species, notably, or the will) may in fact block them. This special sort of self-actualization is compatible, Sutton thinks, with the passivity he ascribes to the potential intellect. (shrink)
