Exploring Aristotle's philosophical method and the merits of his conclusions, Irwin here shows how Aristotle defends dialectic against the objection that it cannot justify a metaphysical realist's claims. He focuses particularly on Aristotle's metaphysics, epistemology, philosophy of mind, and ethics, stressing the connections between doctrines that are often discussed separately.

This article focuses on Cornelio Fabro’s understanding and presentation of Thomas Aquinas’s argumentation for a real distinction and composition of essence and an act of existing (actus essendi) in finite beings, a theory that is closely connected with Aquinas’s notion of transcendental participation. It examines Fabro’s division of Aquinas’s arguments into five gradually developing major approaches. Fabro offers an interesting interpretation of the argument offered by the youthful Aquinas in the often discussed De ente et essentia, c. 4, and finds (...) that in his mature writings Aquinas developed and relied ever more heavily on a proof based on participation.

Michael Wedin argues against the prevailing notion that Aristotle's views on the nature of reality are fundamentally inconsistent. According to Wedin's new interpretation, the difference between the early theory of the Categories and the later theory of the Metaphysics reflects the fact that Aristotle is engaged in quite different projects in the two works--the earlier focusing on ontology, and the later on explanation.

Reale's monumental work establishes the exact dimensions of Aristotle's concept of first philosophy and proves the profound unity of concept that exists in Aristotle's Metaphysics.

DIFFICULTIES about existence have plagued Western thought since the time of Parmenides. The Eleatic sage had concentrated on what was most obvious and most incontrovertible to him, namely, that something exists. He made that tenet the way and the test of truth. From it he drew consequences that succeeding Greek thinkers from Empedocles to Plotinus accepted in part and rejected in part, intrigued by much of what he had stated but repelled by seeming enormities in some of his conclusions. Later, (...) the patristic acceptation of being as the most appropriate name for God gave additional complication to the issue. In modern times the Kantian and linguistic approaches have raised the questions how existence is a predicate and whether there is a concept of it, and if so, what kind of a concept. On the other hand, the impact of Heidegger has inspired renewed and often enthusiastic absorption in the important role played by existence in philosophical thought, and current contacts with Hindu philosophies are furthering this interest.

IN THE PLATONIC TRADITION, the term "participation" signifies the fundamental relationship of both structure and dependence in the dialectic of the many in relation to the One and of the different in relation to the Identical, whereas in Christian philosophy it signifies the total dependence of the creature on its Creator. The term participation has played an extensive role in Patristic and medieval speculation.

The study of being was one of the main preoccupations of Gilson's scholarly and intellectual life. Being and Some Philosophers is at once a testament to the persistence of these concerns and an important landmark in the history of the question of being. The book charts the ways in which being is translated across history, from unity in Plato and substance in Aristotle to essence in Avicenna and the act of existence in Aquinas. It examines the vicissitudes of essence and (...) existence in Suarez and Christian Wolff, in Hegel and Kierkegaard, in order to uncover the metaphysical and existential foundations of modern thought. And yet Being and Some Philosophers remains not so much an historical investigation (although it could only have been written by a scholar steeped in the history of philosophy) but, in the words of its author, "a philosophical book, and a dogmatically philosophical one at that." Its passionate vigour has proven, over many years, at once fresh and provocative. Indeed, the appendix to this revised edition contains critiques of the book by two Thomists as well as Gilson's replies to their objections. (shrink)

Exploring what two foundational figures, Plato and Aristotle, have to say about the nature of human awareness and understanding, Aryeh Kosman concludes that ultimately the virtues of thought are to be found in the joys and satisfactions that come from thinking philosophically, whether we engage in it ourselves or witness others' participation.

Understanding “what something is” has long occupied philosophers, and no Western thinker has had more influence on the nature of being than Aristotle. Focusing on a reinterpretation of the concept of energeia as “activity,” Aryeh Kosman reexamines Aristotle’s ontology and some of our most basic assumptions about the great philosopher’s thought.

In Aquinas on Being and Essence: A Translation and Interpretation, Joseph Bobik interprets the doctrines put forth by St. Thomas Aquinas in his treatise On Being and Essence. He foregrounds the meaning of the important distinction between first and second intentions, the differing uses of the term “matter,” and the Thomistic conception of metaphysics.

In this book, renowned philosopher Ralph McInerny sets out to review what Thomas meant by the phrase and to defend a robust understanding of Thomas's teaching on the subject.

By providing a phenomenological presentation of Aquinas’s duplex operatio intellectus, the author argues that a reader is better equipped to understand where and when Aquinas arrives at the real distinction between essence and existence in the much disputed De Ente et Essentia, chapter four. “Phenomenological presentation” means an honest description of one’s own mental life as it conducts the duplex operatio. From phenomenological observations in the Thomistic texts, the author argues that a penetrative and rebounding movement of attention upon some (...) initially presented multiplicity characterizes the duplex operatio. When this dynamic is conducted upon the multiplicity of a real thing juxtaposed to itself cognitionally existing in sensation, the rebound of the secunda operatio presents the real existence in a sui generis relation of priority to the individual thing understood as existence neutral. Unfortunately, the rebound of attention is too quick to discern accurately the nature of the borderline between the attribute of existence and its subject, the individual thing. The attribute of existence may actuate the thing by shading into it or by remaining distinct from it. Fortunately, the phenomenological situation is sufficient to leave phenomenology and to initiate the third intellectual operation of reasoning. Reasoning concludes to a first cause of phenomenologically observable attributive existence. In this first cause existence is the thing itself. In order for this first cause to have its proper effect corresponding to what it is, the author argues that the second of the above two alternatives for phenomenologically observable attributive existence must be the true one. After linking these reflections to stages of De Ente, chapter 4, the author critically relates them to other interpretations of the text. These interpretations include those of Cahalan, McDonald, Wippel, Dewan, Patt, Kenny, and Owens. (shrink)

Aristotle’s notion of substance and its relation to his investigation of the question of being qua being in the Metaphysics is one of the most important, enduring, and intriguing problems in scholarship focused on Aristotle and the tradition of metaphysics. This article explores some of the more recent developments in this area of scholarship, especially the trend toward more dynamic interpretations of Aristotle’s conception of substance, as a way of renewing the question of what Aristotle really means by being. On (...) this basis, the article reinterprets Aristotle’s investigation of substance as the primary sense of being in the Metaphysics. It argues that there are two primary ways substance may be considered; with respect to the principles of intelligibility of substance and with regard to the causal framework of the real unity and determinacy of substance. The primary principles of the intelligibility of substance, it is argued, are end and fulfilment (telos and entelechy). The causal framework of the real unity and determinacy of substances, on the other hand, can be understood via the notion of act and activity (energeia). (shrink)
