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 untreated by Kerr. For the sake of the “formally inclined” reader, the paper’s treatment will also include an Appendix offering a formal reconstruction of both the main argument and its sub-arguments to demonstrate the formal rigor of Aquinas’ original.

This course covers paradigmatic accounts of human nature in ancient, medieval, and early modern philosophy, through a careful reading of selected primary texts and contemporary commentary. Major topics will include knowledge and opinion; body and soul; immortality, rationality, and freedom of the will; created being and goodness as emanations of divine perfection. The main focus of the discussions will be on the metaphysical foundations of moral value in the pre-modern tradition, and the conceptual changes shaking these metaphysical foundations with the emergence of modern philosophy.

Let me begin my reply to Professor Roark’s objections in good old scholastic fashion, by a distinction. Philosophical objections can be good in two senses. In the first, trivial sense, a good objection is one that convincingly shows the presence of a genuine error in a position or reasoning. Such objections are useful, but uninspiring. In the second, non-trivial sense, a good philosophical objection broadens and deepens our understanding of the problems at issue, whether or not they manage to refute the opponent’s position. In this reply I am going to argue that even if Roark’s objections may not be necessarily good in the first, trivial sense, they are..

One often hears extravagant claims made for the Aristotelian doctrine that "what understands and what is understood are the same" De anima iii.4; 430a4). This identity between knower and what is known, or between percipient and what is perceived, is often said to offer a way out of the familiar skeptical arguments against the possibility of our having knowledge of the external world. Typically such claims are made by students of Thomas Aquinas, who in this way seek to render Aquinas's theory of knowledge immune from the skeptical and idealist controversies of modern philosophy. In this paper I argue that Aquinas put this doctrine of identity to no such use, that in fact he explicitly rejects any such use of the doctrine, and that furthermore no plausible reading of the doctrine could conceivably produce such dramatic results.

`Realism', `conceptualism' and `nominalism' are terms that one is most likely to come across in history of philosophy textbooks, presented as ones labeling three major ontological alternatives provided by mediaeval philosophy. The general inadequacy of these labels is perhaps best shown by the desperate efforts to provide further, modified labels , the well-known `moderate' and `extreme' or `exaggerated' versions of the above, in hopes of implying at least a lesser amount of falsehood in hanging..

This paper argues for two principal conclusions about natural language semantics based on John Buridan's considerations concerning the notion of formal consequence, that is, formally valid inference. (1) Natural languages are essentially semantically closed, yet they do not have to be on that account inconsistent. (2) Natural language semantics has to be token based, as a matter of principle. The paper investigates the Buridanian considerations leading to these conclusions, and considers some obviously emerging objections to the Buridanian approach

Summary: The aim of this paper is to explore the relationships between Buridan’s logic and the ontology of modes modi). Modes, not considered to be really distinct from absolute entities, could serve to reduce the ontological commitment of the theory of the categories, and thus they were to become ubiquitous in this role in late medieval and early modern philosophy. After a brief analysis of the most basic argument for the real distinction between entities of several categories (“the argument from separability”), I point out that despite nominalist charges to the contrary, “older realists”—that is, authors working before and around Ockham’s time—were not committed to such real distinctions, and thus to an overpopulated ontology, by their..

In order to make this point, in the next section I will present a very simple, intuitive reconstruction of Anselm’s argument. Then, in the third section, I will show that since the argument thus reconstructed is obviously valid, and it would be foolish to challenge any other of its premises except the assumption that God does not exist in reality, it is a sound proof of God’s existence. Nevertheless, in the fourth section, I will argue further that despite its soundness, this proof can rationally be rejected by anyone who refuses to think..

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 plausibly be denied in Aquinas’ own conceptual framework. Since the issue of consistency merely assumes the less than self-evident claim of the immateriality of the human intellect, I will also provide a brief sketch of what I take to be Aquinas’ most promising proof of this claim.

This paper confronts a certain modern view of the relation between semantics and ontology with that of the late-medieval nominalist philosophers, William Ockham and John Buridan. The modern view in question is characterized in terms of what is called here “the thesis of onto-semantic parallelism,” which states that the primitive (indefinable) categorematic concepts of our semantics mark out the primary entities in reality. The paper argues that, despite some apparently plausible misinterpretations to the contrary, the late-medieval nominalist program of “ontological reduction” was not driven by considerations that try to “read off” ontology from semantic analysis or those that try to identify semantic primitives in their search for ontological primitives. The medieval authors presented a much more flexible, dynamic view of “Aristotelian naturalism,” which challenges both of the unappealing modern alternatives of “conceptual tribalism” and “conceptual imperialism.”

This paper primarily aims to provide a coherent interpretation of several, apparently conflicting claims made by Aquinas concerning the semantic function of the copula. The paper also argues that these claims can properly be understood only if they are interpreted as forming a coherent part of Aquinas' larger theory of the analogy of being. The Appendix sketches a model theoretical semantics for the reconstruction of Aquinas' relevant ideas, providing the technical means for setting apart the various senses of the verb 'est' and its cognates distinguished by Aquinas

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 principles (requiring accidents existing without a substance, and a body in several places at the same time, etc.), and dividing schools of thought, indeed, eventually, warring religious factions. The volume addresses both the metaphysical, theoretical issues involved in this challenge and the historical, theological developments of how meeting this challenge played out first in the schools and even later in religious schisms, leading to the paradigmatic shift from medieval to modern forms of thought. The essays of the volume derive from the lectures of an eponymous international conference held in Budapest, Hungary, which was also the occasion of founding the Society for the History of European Ideas (SEHI); accordingly, the book is the first volume of the annual Proceedings of the SEHI. This book is aimed just as much at laymen and religious scholars seeking a better understanding of their faith as at anyone seeking this understanding with a non-religious attitude.

Anthony Kenny's book is one of the best of its genre, exemplifying the kind of introduction into (some field of) Aquinas's thought that endeavors to make his ideas accessible to the philosophically interested contemporary reader in terms of such philosophical, scientific and everyday concepts with which the reader can safely be assumed to be familiar. Indeed, Kenny's book provides us with such a good example of this genre that it brings into sharp focus the problems of the genre itself. Therefore, while duly acknowledging the book's virtues of clarity of presentation, and its highly readable, almost conversational style, let me concentrate in this brief review on this problematic aspect of Kenny's book, as someone who is just as much concerned with making Aquinas accessible to a contemporary audience as the author is.
