Paul Ricoeur (1913-2005) was one of the outstanding French philosophers of the 20th century and his work is widely read in the English-speaking world. This unique volume comprises the lectures that Ricoeur gave on Plato and Aristotle at the University of Strasbourg in 1953-54. The aim of these lectures is to analyse the metaphysics of Plato and Aristotle and to discern in their work the ontological foundations of Western philosophy. The relation between Plato and Aristotle is commonly portrayed as a contrast between a philosophy of essence and a philosophy of substance, but Ricoeur shows that this opposition is too simple. Aristotelian ontology is not a simple antithesis to Platonism: the radical ontology of Aristotle stands in a far more subtle relation of continuity and opposition to that of Plato and it is this relation we have to reconstruct and understand. Ricoeur’s lectures offer a brilliant analysis of the great works of Plato and Aristotle which has withstood the test of time. They also provide a unique insight into the development of Ricoeur’s thinking in the early 1950s, revealing that, even at this early stage of his work, Ricoeur was focused sharply on issues of language and the text.

In this book, Theodore Scaltsas brings the insights of contemporary philosophy to bear on a classic problem in metaphysics that stems from Aristotle's theory of substance. Scaltsas provides an analysis of the enigmatic notions of potentiality and actuality, which he uses to explain Aristotle's substantial holism by showing how the concrete and the abstract parts of a substance form a dynamic, diachronic whole.

In this book, Vasilis Politis argues that Plato's Forms are essences, not merely things that have an essence. Politis shows that understanding Plato's theory of Forms as a theory of essence presents a serious challenge to contemporary philosophers who regard essentialism as little more than an optional item on the philosophical menu. This approach, he suggests, also constitutes a sharp critique of those who view Aristotelian essentialism as the only sensible position: Plato's essentialism, Politis demonstrates, is a well-argued, rigorous, and coherent theory, and a viable competitor to that of Aristotle. This book will appeal to students and scholars with an interest in the intersection between philosophy and the history of philosophy.

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.

Substance and Essence in Aristotle is a close study of Aristotle's most profound—and perplexing—treatise: Books VII-IX of the Metaphysics. These central books, which focus on the nature of substance, have gained a deserved reputation for their difficulty, inconclusiveness, and internal inconsistency. Despite these problems, Witt extracts from Aristotle's text a coherent and provocative view about sensible substance by focusing on Aristotle's account of form or essence. After exploring the context in which Aristotle's discussion of sensible substance takes place, Witt turns to his analysis of essence. Arguing against the received interpretation, according to which essences are classificatory, Witt maintains that a substance's essence is what causes it to exist. In addition, Substance and Essence in Aristotle challenges the orthodox view that Aristotelian essences are species-essences, defending instead the controversial position that they are individual essences. Finally, Witt compares Aristotelian essentialism to contemporary essentialist theories, focusing in particular on Kripke's work. She concludes that fundamental differences between Aristotelian and contemporary essentialist theories highlight important features of Aristotle's theory and the philosophical problems and milieu that engendered it.

A new interpretation of Aristotle's metaphysics, a subject of considerable interest to all classical philosophers.

This book argues that according to Metaphysics Zeta, substantial forms constitute substantial being in the sensible world, and individual composites make up the basic constituents that possess this kind of being. The study explains why Aristotle provides a reexamination of substance after the Categories, Physics, and De Anima, and highlights the contribution Z is meant to make to the science of being. Norman O. Dahl argues that Z.1-11 leaves both substantial forms and individual composites as candidates for basic constituents, with Z.12 being something that can be set aside. He explains that although the main focus of Z.13-16 is to argue against a Platonic view that takes universals to be basic constituents, some of its arguments commit Aristotle to individual composites as basic constituents, with Z.17’s taking substantial form to constitute substantial being is compatible with that commitment. .
