4Aquinas’ Solution of the Problem of the Persistence of Accidents in the Eucharist and Its Impact on Later Developments in the European History of IdeasIn The Metaphysics and Theology of the Eucharist: A Historical-Analytical Survey of the Problems of the Sacrament, Springer Verlag. pp. 199-212. 2023.This chapter focuses on how Aquinas’ solution of the problem of the persistence of eucharistic species and other scholastics’ reactions to it opened up certain conceptual possibilities in the Scholastic Aristotelian tradition that would not have been there without it, and which, therefore, were pointing the way toward later conceptual developments in the post-medieval and early modern philosophical traditions in logic, and metaphysics.

20The Metaphysics and Theology of the Eucharist: A Historical-Analytical Survey of the Problems of the Sacrament (edited book)Springer Verlag. 2023.This volume is about the most mind-boggling sacrament of the Christian faith, also referred to as the Sacrament of the Altar, the Eucharist: in its Roman Catholic interpretation, the conversion of the substance of the bread and wine into the body and blood of Christ for Holy Communion. The challenge of providing a rational interpretation of this doctrine of faith proved to be one of the most contentious issues in the Western history of ideas, apparently going against self-evident metaphysical pr…Read more

15Aquinas vs. Buridan on the Universality of Human Concepts and the Immateriality of the Human IntellectPhilosophica: International Journal for the History of Philosophy 30 (1): 33-47. 2022.Under the traditional classification of medieval positions on the issue of universals, both Aquinas and Buridan would have to be deemed to be “conceptualists”: they both deny the existence of mind-independent, Platonic universals (against “realists”), and they both attribute universality primarily to the representative function of our universal concepts, and thus only secondarily to universal names of human languages (against “nominalists”). Yet, Aquinas is quite appropriately classified as a “m…Read more

5The Metaphysics of Habits in BuridanIn Nicolas Faucher & Magali Roques (eds.), The Ontology, Psychology and Axiology of Habits (Habitus) in Medieval Philosophy, Springer. pp. 321-331. 2018.This paper presents John Buridan’s nominalist ontology of habits, as the acquired qualities of innate powers aiding or hampering their operations, against the background of a more traditional interpretation of Aristotle’s doctrine to be found in Boethius, Albert the Great, Thomas Aquinas, and Cajetan. The paper argues that considerations of his late question commentary on Aristotle’s Nicomachean Ethics may have forced Buridan to rethink some of his earlier arguments for his parsimonious nominali…Read more

230Artificial intelligence and its natural limitsAI and Society (1): 9-18. 2021.An argument with roots in ancient Greek philosophy claims that only humans are capable of a certain class of thought termed conceptual, as opposed to perceptual thought, which is common to humans, the higher animals, and some machines. We outline the most detailed modern version of this argument due to Mortimer Adler, who in the 1960s argued for the uniqueness of the human power of conceptual thought. He also admitted that if conceptual thought were ever manifested by machines, such an achieveme…Read more

54Aquinas’s Real Distinction and Its Role in a Causal Proof of God’s ExistenceRoczniki Filozoficzne 67 (4): 7-26. 2019.This paper is not going to offer any criticism of the way Gaven Kerr treats Aquinas’ argument. Instead, it offers an alternative way of reconstructing Aquinas’ argument, intending to strengthen especially those controversial aspects of it that Kerr’s reconstruction left untreated or in relative obscurity. Accordingly, although the paper’s treatment will have to have some overlaps with Kerr’s, it will deal with issues essential to adequate replies to certain competent criticisms of his argument u…Read more

33Aquinas’ Balancing ActBochumer Philosophisches Jahrbuch Fur Antike Und Mittelalter 21 (1): 29-48. 2018.In this paper, I will primarily argue for the consistency of Aquinas’ conception, according to which the human soul, uniquely in God’s creation, is both the inherent, material, substantial form of the human body, and the subsistent immaterial substance underlying the immaterial operations of its immaterial, rational powers, namely, intellect and will. In this discussion, I will point out that typical challenges to Aquinas’ conception usually rely on semantic or ontological assumptions that can p…Read more

217Intentionality, Cognition, and Mental Representation in Medieval Philosophy (edited book)Fordham University Press. 2015.It is supposed to be common knowledge about the history of ideas that one of the few medieval philosophical contributions preserved in modern philosophical thought is the idea that mental phenomena are distinguished from physical phenomena by their intentionality, their directedness toward some object. As is usually the case with such commonplaces about the history of ideas, this claim is not quite true. Medieval philosophers routinely described ordinary physical phenomena, such as reflections i…Read more
