This book collects six unpublished and published academic studies on the thought of Francisco Suárez, which is addressed through accurate textual analyses and meticulous contextualization of his doctrines in the Scholastic debate. The present essays aim to portray two complementary aspects coexisting in the work of the Uncommon Doctor: his innovative approach and his adherence to the tradition. To this scope, they focus on some pivotal, but often neglected, topics in Suárez’s metaphysics and psychology – such as his theories of (...) cognition and truth, angelology, continuous quantity – thereby developing an original inquiry into a crucial moment in the development of Western philosophy.

It seems quite natural that we have cognitive access not only to things around us, but also to our own acts of perceiving and thinking. How is this access possible? How is it related to the access we have to external things? And how certain is it? This paper discusses these questions by focusing on Francisco Suárez’s theory, which gives an account of various forms of access to oneself and thereby presents an elaborate theory of consciousness. It argues that Suárez (...) clearly distinguishes between first-order sensory consciousness and second-order intellectual consciousness. Moreover, Suárez attempts to explain the unity of consciousness by referring to a single soul with hierarchically ordered faculties that is responsible both for first-order and for second-order consciousness.

This article explores the epistemological ramifications of understanding Thomas Aquinas’ conception of truth in terms of a dynamic process of cognitive assimilation within the human psyche. In particular, the author addresses two potential pitfalls for his theory, namely ‘failed assimilation’ as the basis of false judgments and ‘negative assimilation’, i.e., correspondence to non-being: how is the human mind capable of assimilation to ‘nothing’ at all? Aquinas addresses these two problems in various passages throughout his works; the author connects and reviews (...) their arguments with regard to their philosophical cogency and attempts to answer the question of whether Aquinas ultimately succeeds in solving the several puzzles that ‘failed’ as well as ‘negative assimilation’ seem to create in his conception of truth.

In De Anima Book III, Aristotle subscribed to a theory of formal identity between the human mind and the extra-mental objects of our understanding. This has been one of the most controversial featu...

The paper argues in favour of a direct realist reading of Aquinas’s theory of intelligible species, in opposition to the recent representationalist challenges. In order to secure the direct realist reading, the paper follows three steps: a short description of Aquinas’s process of cognition, a survey of the direct realist arguments and the analysis of the representationalist interpretation. The final step consists of investigating the representationalist reading as it is suggested by two scholars, Claude Panaccio in Aquinas on Intellectual Representation (...) and Robert Pasnau in Theories of Cognition in the Latter Middle Ages. Thus, the paper can be construed as a reply to these two authors, due to the thorough attention paid to their argumentative trails. With regard to Panaccio’s reading the paper focuses on the identity between the intelligible species and the essence of the extra-mental object and argues that Panaccio understands identity in a very narrow sense. Concerning Pasnau’s line of reasoning the focus is on the primum cognitum status of the intelligible species, and the main argument is that intelligible species is understood by Aquinas as the quo and not the quod of cognition. As the paper shows, neither one, nor the other interpretation poses a threat to the direct realist reading of Aquinas’s intelligible species. (shrink)

The present dissertation concerns cognitive psychology—theories about the nature and mechanism of perception and thought—during the High Middle Ages (1250–1350). Many of the issues at the heart of philosophy of mind today—intentionality, mental representation, the active/passive nature of perception—were also the subject of intense investigation during this period. I provide an analysis of these debates with a special focus on Durand of St.-Pourçain, a contemporary of John Duns Scotus and William of Ockham. Durand was widely recognized as a leading philosopher (...) until the advent of the early modern period, yet his views have been largely neglected in the last century. The aim of my dissertation, then, is to provide a new understanding of Durand’s cognitive psychology and to establish a better picture of developments in cognitive psychology during the period. -/- Most philosophers in the High Middle Ages held, in one form or another, the thesis that most forms of cognition (thought, perception) involve the reception of the form of the object into the mind. Such forms in the mind explain what a given episode of cognition is about, its content. According to what has been called the conformality theory of content, the content of our mental states is fixed by this form in the mind. Durand rejects this thesis, and one of the primary theses that I pursue is that Durand replaces the conformality theory of content with a causal theory of content, according to which the content of our mental states is fixed by its cause. When I think about Felix and not Graycat, this is to be explained not by the fact that I have in my mind the form of Felix and not Graycat, but rather by the fact that Felix and not Graycat caused my thought. -/- This is both a controversial interpretation and, indeed, a controversial theory. It is a controversial interpretation because Durand seems to reject the thesis that objects are the causes of our mental states. In the first half of the present dissertation, I argue that Durand does not reject this thesis but he rejects another nearby thesis: that objects as causes give to us ‘forms’. On Durand’s view, an object causes a mental state even though it does not give to us a new ‘form’. In the second half of the dissertation I defend Durand’s causal theory of content against salient objections to it. (shrink)

Most philosophers in the High Middle Ages agreed that what we immediately perceive are external objects. Yet most philosophers in the High Middle Ages also held, following Aristotle, that perception is a process wherein the perceiver takes on the form or likeness of the external object. This form or likeness — called a species — is a representation by means of which we immediately perceive the external object. Thomas Aquinas defended this thesis in one form, and Durand of St.-Pourçain, his (...) Dominican successor, rejects it. This paper explores Durand's novel criticism of Aquinas's species-theory of cognition. I first develop and defend a new interpretation of Durand's central criticism of Aquinas's theory of cognition. I close with some considerations about Durand's alternative to the theory. -/- . (shrink)
