Thomas Wylton's Quaestio de anima intellectiva is one of the most significant medieval treatments of the intellectual soul. This edition of the Latin text is accompanied by an en face English translation by Gail Trimble. The detailed introduction guides the reader through the intricacies of the transmission of the text as well as its philosophical contents. -/- Wylton's Quaestio presents a strong and controversial defence of Averroes' interpretation of Aristotelian psychology. In his comparison of Averroes' view with the Catholic doctrine (...) of the human soul, as defined by the Council of Vienne, Wylton highlights the rationality of the Arabic philosopher's stance and raises strong arguments against the commonly accepted opinion of Catholic thinkers, such as Thomas Aquinas and his followers. Wylton's Quaestio had a strong influence on his contemporaries and in particular on the most eminent exponent of Latin Averroism, John of Jandun, who included long passages from Wylton's treatise in his commentary on Aristotle's On the Soul. -/- Wylton also addresses fundamental philosophical issues: the ontological status of a subsisting form, the existence of universal things as components of individuals, and the possibility of intellectual knowledge of universals as well as singulars. This combination of polemics and engaging philosophical reflection is one of the distinguishing features of Wylton's text and makes his work of significance to historians, philosophers, and theologians.

In this paper, I argue that Ockham’s seemingly pessimistic epistemological assessments of what we can know about the human soul and its relation to the body reflect a sound appreciation of what is involved in the theoretical development of philosophy and natural science. In order to make my argument, I first undermine the idea that demonstration was a norm that scholastic disputation regularly expected to achieve; and second, I examine Ockham’s treatment of three major topics in psychology (thus illustrating how (...) alternative intellectual standards were in play in scholastic disputation).

Abstract This paper studies Olivi's account of perceptual representation. It addresses two main questions: (1) how do perceptual representations originate? and (2) how do they represent their objects? Regarding (1), it is well known that Olivi emphasizes the activity of the soul in the production of perceptual representations. Yet it is sometimes argued that he overstresses the activity of the soul in a way that yields a philosophically problematic result. I argue that Olivi was well aware of the problem that (...) could be raised for his theory and that he sought to cope with it. Regarding (2), Pasnau argues that for Olivi, causal relationships with external objects determine the content of perceptual representations. I argue that, rather, perceptual representations are about their objects because they are their similitudes. This makes him an internalist about representational content. (shrink)

Im Folgenden werde ich einige der möglichen Interpretationen der thomistischen Intentionalitätstheorie darstellen. Zuerst werde ich die Mechanismen der menschlichen Erkenntnis und der Beziehung zwischen phantasmata, species sensibile und species intelligibile bei Thomas von Aquin beschreiben. Danachwerde ich die verschiedenen Interpretationen des Problems der Intentionalität bei Thomas darstellen; genauer gesagt geht es um drei reduktive Interpretationenund eine nicht-reduktive. Am Ende dieses Beitrags werde ich mich für eine dieser Interpretationen entscheiden und meine Gründe dafür angeben.

My aim in this paper is to advance our understanding of medieval approaches to consciousness by focusing on a particular but, as it seems to me, representative medieval debate. The debate in question is between William Ockham and Walter Chatton over the existence of what these two thinkers refer to as “reflexive intellective intuitive cognition”. Although framed in the technical terminology of late-medieval cognitive psychology, the basic question at issue between them is this: Does the mind (or “intellect”) cognize its (...) own states via higher-order (or “reflexive”) representational states? Their debate is representative both because it highlights the central dialectical issues and alternatives at play in medieval discussions of consciousness generally and because it showcases the two main types of approach to consciousness one finds in the later medieval period, namely, those that explain consciousness in terms of intentionality (typically, higher-order intentionality), and those that understand consciousness as a non-intentional, sui-generis mode of awareness.

In this paper I will delineate the psychological operations and faculties required for linguistic apprehension within a Thomistic psychology. This will require first identifying the proper object of linguistic apprehension, which will then allow me to specify the distinct operations and faculties necessary for linguistic apprehension. I will argue that the semantic value of any linguistic term is a type of incidental sensible and that its cognitive apprehension is a type of incidental sensation. Hence, the faculties necessary for the apprehension (...) of any linguistic term’s semantic value will be the cogitative power and the intellect. The cogitative power, because it is the faculty of particular intentions, and the intellect, because it is the faculty of universal intentions. (shrink)

I will defend a principle at work in Thomas Aquinas’s argument that the human intellect must be immaterial in order to know material things in SummaTheologica, Ia, q.75, a.2. Thomas relies on the position that whatever knows certain things would be impeded in this knowledge if it contained in itself thesesame things. Thus, if humans can, in principle, know all material things, then the intellect cannot be material. The position that a material intellect would be limited in knowledge of material (...) things is perhaps the most controversial part of the argument. I will articulate a version of this argument and argue that two objections to Thomas’s argument, offered by Norman Kretzmann and Robert Pasnau, fail, due in large part to a misunderstanding of proper objects of cognition.

The article describes the evolution of Ockham's theory of mental language and its impact on three of his dominican contemporaries at oxford: Hugh Lawton, William Crathorn and Robert Holcot, and its impact at Paris on the works of Gregory of Rimini and Pierre d'Ailly. Hugh Lawton's critical response to Ockham relied on a liar-like paradox to show that mental language would preclude the ability to lie. Crathorn devised an alternative to Ockham's theory in reaction, whereas Holcot defended Ockham's views. At (...) Paris, the debate suggested a solution to the liar paradox to Gregory of Rimini.

Wilfrid Sellars, in his essay “Being and Being Known,”1 sets out to explore “the profound truth contained in the Thomistic thesis that the senses in their way and the intellect in its way are informed by the natures of external objects and events” [§1]. Profound truth there may be, but Sellars also finds a profound error in the mediæval treatment of the intentionality of sensing on a par with the intentionality of thinking: There are many reasons for the plausibility of (...) the idea that sense belongs to the intentional order. . . It is primarily due, however, to the fact that sensations have what I shall call a pseudo-intentionality which is easily mistaken for the genuine intentionality of the cognitive order. [§18] Sellars argues that thought is genuinely intentional, for it is (in good linguistic fashion) about the world, whereas sense merely seems to be about the world but in fact is not, although it is systematically correlated with the world—the ‘pseudo-intentionality’ he alludes to here. On Sellars’s reading, the ‘Thomistic’ view gets certain things right that the later Cartesian view gets wrong, such as distinguishing mental acts intrinsically rather than by their ‘content’, but it also gets some things wrong in its own right, notably in its claim that sensing has “genuine intentionality” the way thinking does, and so to take sensing as properly belonging to “the cognitive order” (i. e. to qualify as a kind of knowledge strictly speaking). Sellars is out to right the Thomistic wrongs, beginning with intentionality, where the mistake is easily made. For Sellars has his eye not only on intentionality, but on the consequent claim that episodes of (intentional) sensing play a foundationalist epistemological role, a view he elsewhere famously calls ‘The Myth of the Given’.2 There is no question that Sellars wants to make room for his own brand of social epistemology; his agenda is not historical but systematic. Yet in “Being and Being Known,” Sellars puts his case in historical rather than systematic terms.. (shrink)

In one corner Socrates; in the other, on the mat, his cat Felix. Socrates, of course, thinks (correctly) that Felix the Cat is on the mat. But there’s the rub. For Socrates to think that Felix is on the mat, he has to be able to think about Felix, that is, he has to have some sort of cognitive grasp of an individual — and not just any individual, but Felix himself. How is that possible? What is going on when (...) we think about things? (shrink)

Mediaeval psychological theory was a “faculty psychology”: a confederation of semiautonomous sub-personal agents, the interaction of which constitutes our psychological experience. One such faculty was intellective appetite, that is, the will. On what grounds was the will taken to be a distinct faculty? After a brief survey of Aristotle's criteria for identifying and distinguishing mental faculties, I look in some detail at the mainstream mediaeval view, given clear expression by Thomas Aquinas, and then at the dissenting views of John Duns (...) Scotus and William of Ockham. I conclude with some reflections on why the mainstream mediaeval view was discarded by Descartes. (shrink)

Thomas of Sutton was one of the earliest, and by all measures one of the most astute defenders of St. Thomas Aquinas’ characteristic theological and philosophical doctrines. As usual with medieval thinkers, we have little information regarding Sutton’s life..

This article examines one aspect of Thomas Aquinas' understanding of abstraction. It shows in which way, according to Aquinas, universal material objects and individual material objects are the starting point for mathematical objects. It comes to the conclusion that for Aquinas there are not only universal mathematical objects (circle, line), but also individual mathematical objects (this circle, that line). Universal mathematical objects are properties of universal material objects and individual mathematical objects are properties of individual material objects. One type of (...) abstractio formae leads from individual material objects to universal mathematical objects, a second type from universal material objects to universal mathematical objects, and a third type from individual material objects to individual mathematical objects. Therefore, the concept of abstractio formae is ambiguous. (shrink)

In this paper, I argue that it is in the fourteenth century that the problem of the compatibility or unity of efficient and final causality emerges. William Ockham and John Buridan start to flirt with a mechanized view of nature solely explainable by efficient causality, and they hence push final causality into the human mind and use it to explain for example action, morality and the good. Their argumentation introduces the problem of how to give a unified account of the (...) world, that is, how are nature and freedom compatible. In the paper, I set up the discussion by going through some of the problems associated with final causality in the seventeenth century and show that Ockham and Buridan's problems are similar. I then argue using a formulation from Leibniz's Monadology that the problems here traced should be seen as versions of the mind/body problem. (shrink)

I argue that Nicholas of Cusa agrees with Thomas Aquinas on the metaphysics of analogy in God, but differs on epistemology, taking a Platonic position against Aquinas’ Aristotelianism. As a result Cusa has to rethink Thomas’ solution to the problem of discourse about God. In De docta ignorantia he uses the mathematics of the infinite as a clue to the relations between a thing and its Measure and this allows him, he thinks, to adapt Aquinas’ approach to the problem of (...) his own epistemology. The resulting approach, I maintain, is coherent and reasonable if the metaphysical views behind it are. (shrink)

Buridan's theory of sentences with epistemic verbs (`to know', `to believe', etc.) has received much attention in recent scholarship. Its originality with respect to Ockham's approach, however, has been importantly overestimated. The present paper argues that both doctrines share crucial features and basically belong to the same family. This is done by comparing Buridan's notion of the `appellation of reason' with Ockham's application to epistemic sentences of the general principle that a predicate always `appellates its form'.

This paper studies the doctrinal and historical relations between the augustinian theme of the inner word as it was understood in Thirteenth-century thought --especially by Thomas Aquinas -- and William of Ockham's idea of mental discourse. The differences are shown to be deeply significant and are replaced in the context of a crucial shift that occurred in the decades between Aquinas and Ockham: the shift from theology to logic as providing the main inputs and stimulations for the development, on an (...) aristotelian basis, of a radically new sort of philosophy of mind.

For later medieval philosophers, writing under the influence of Aristotle’s natural philosophy and metaphysics, the human soul plays two quite different roles, serving as both a substantial form and a mind. To ask the natural question of why we need a soul at all – why we might not instead simply be a body, a material thing – therefore requires considering two very different sets of issues. The first set of issues is metaphysical, and revolves around the central question of (...) why a human being needs a substantial form. The second set of issues is psychological, and turns on the question of why we should suppose that our mind is aptly characterized as a soul. This chapter takes up these two questions in turn, and then turns to whether we should suppose that one and the same thing – a soul – is both substantial form and mind. This dual-function thesis is the most distinctive feature of later medieval psychology, and is one reason that work from this era remains well-worth reading today. Whereas modern thought furnishes many sophisticated discussions of the immateriality of mind, and the metaphysics of body, philosophers since Descartes have rarely considered that it might be one thing, the soul, that accounts for both thought and substantial unity.

Medieval epistemology begins as ideal theory: when is one ideally situated with regard to one's grasp of the way things are? Taking as their starting point Aristotle's Posterior Analytics, scholastic authors conceive of the goal of cognitive inquiry as the achievement of scientia, a systematic body of beliefs, grasped as certain, and grounded in demonstrative reasons that show the reason why things are so. Obviously, however, there is not much we know in this way. The very strictness of this ideal (...) in fact gives rise to a body of literature on how Aristotle's framework might be relaxed in various ways, for certain specific purposes. In asking such questions, scholastic authors are in effect pursuing the project of social epistemology, by trying to adapt their ideal theory to the circumstances of everyday life. (shrink)

In an earlier work, I proposed understanding Aquinas’s theory of cognition in terms of the possession of information about the world. This proposal has seemed problematic in various ways. It has been said to include too much, and too little, and to be the wrong sort of account altogether. Nevertheless, I continue to think of it as the most plausible interpretation of Aquinas’s theory.

William of Ockham held in his career two different theories about the nature of concepts. According to the first theory, concepts are forged by the mind and "terminate" the mental acts which produce them. This so called "fictum"-theory was abandoned, and Ockham held another theory, according to which concepts are identified with the mental acts themselves. While I think this is a correct description of the evolution of his philosophy, there is one aspect that has gone so far (almost) unnoticed (...) : in his later theory, not only concepts do not terminate mental acts, but nothing seems fit to play this role. Mental acts are no longer "terminated" by anything. Therefore, as the theory of concepts changes, there is also a change in the theory of mental acts. This last change explains the disappearance of the vocabulary associated with the verb "terminare" in the exposition of the mental act theory. (shrink)

Medieval philosophers clearly recognized that emotions are not simply "raw feelings" but complex mental states that include cognitive components. They analyzed these components both on the sensory and on the intellectual level, paying particular attention to the different types of cognition that are involved. This paper focuses on William Ockham and Adam Wodeham, two fourteenth-century authors who presented a detailed account of "sensory passions" and "volitional passions". It intends to show that these two philosophers provided both a structural and a (...) functional analysis of emotions, i.e., they explained the various elements constituting emotions and delineated the causal relations between these elements. Ockham as well as Wodeham emphasized that "sensory passions" are not only based upon cognitions but include a cognitive component and are therefore intentional. In addition, they pointed out that "volitional passions" are based upon a conceptualization and an evaluation of given objects. This cognitivist approach to emotions enabled them to explain the complex phenomenon of emotional conflict, a phenomenon that has its origin in the co-presence of various emotions that involve conflicting evaluations.

Francis of Marchia dealt at length in several different contexts with the nature of the will and willing. Here I examine just one of those discussions: the possibility for the will to go against reason's final judgment, a topic related to weakness of will and the source of sin. Marchia is clearly of a voluntaristic bent, holding that the will can indeed act against the determination of reason. After examining Marchia's argumentation for his position, I explore some of the background (...) to Marchia's view in a distinctively later medieval understanding of the human mind as a system of internal acts and dispositions, with the possibility that several of them belong to the same faculty simultaneously. This increasingly complex conceptualisation of the mind mirrors a new, more complex conceptualization of the "Self". (shrink)

There has been a renewed interest of late in the thought of Henry of Ghent.1 Scholars have recognized that Henry was an influential figure at the University of Paris in the late-thirteenth century and that his influence extended well past his own generation. It is also widely acknowledged that Henry's thought developed significantly over the span of his career.2 The critical edition of Henry's works has proven to be crucial in assessing this development.3 Nonetheless there is little consensus on the (...) nature of the development, particularly with respect to his theory of cognition. One reason for the diversity of opinions is that no single trend can be identified in his doctrine as a whole; rather, distinct .. (shrink)

According to Marin Cureau de La Chambre—steering a middleway between the Aristotelian and the Cartesian conception of the soul—everything that lives cognizes and everything that cognizes is alive. Cureau sticks with the general tripart distinction of vegetative, sensitive, and intellectual soul. Each part of the soul has its own cognition. Cognition is the way in which living beings regulate bodily equilibirum and environmental navigation. This regulative activity is gouverned by acquired or by innate images. Natural cognition (or instinct) is cognition (...) by innate images only. Cureau develops a highly originel theory of natural (or 'specialized') instinct. His theory attempts to explain five features of instinct (innateness, specialization, species-specifitiy, coerciveness, teleological nature). According to my interpretation, Cureau proposes a species of what is called a 'teleosemantic theory' of innate cognition. (shrink)
