A distinguished group of scholars of ancient philosophy here presents a systematic study of the twelfth book of Aristotle's Metaphysics. Lambda, which can be regarded as a self-standing treatise on substance, has been attracting particular attention in recent years, and was chosen as the focusof the fourteenth Symposium Aristotelicum, from which this volume derives. At the Symposium, each of Lambda's ten chapters was taken in turn as the subject of a session at which a specially written paper was read to and discussed by the assembled symposiasts. (The ninth chapter commanded twosessions by dint of its particular difficulty.) The papers have been revised in the light of discussion, and are now offered to a wider audience as a discursive commentary on points of particular philosophical interest covering all of Lambda. Michael Frede's extensive Introduction aims to give abroader view of Lambda as a whole and the problems it raises, and thus to provide the context for the discussion of each of the chapters. This volume will be a resource of great value and interest for anyone working on ancient metaphysics and theology.

In this annotated critical edition of Aristotle’s Metaphysics Lambda Stefan Alexandru explores and utilizes for the first time numerous previously neglected textual sources, written in Greek, Latin, Arabic, and Hebrew. The twelfth book of the Metaphysics, originally an independent treatise, is crucial for the understanding of Aristotle’s philosophy, primarily because the doctrine of the Unmoved Mover is nowhere else set forth in greater detail. Not only all the forty-two formerly known Greek codices have been collated, but also commentaries and translations. Moreover, a hitherto undiscovered, independent manuscript, representing a tenuous and particularly valuable branch of the direct tradition, is minutely investigated. The document in question, preserved in the Vatican, is an autograph of the Byzantine humanist and Ecumenical Patriarch Gennadios II Scholarios.

The treatise known as book Lambda of Aristotle’s Metaphysics has become one of the most debated issues of recent scholarship. Aristotle adresses here fundamental questions of his theory of substance, his idea of causes and principles, and his concept of motions. Furthermore, the importance of the text is due to the fact that it contains an outline of what was traditionally understood as Aristotle’s theology.

"This addition to the Clarendon Aristotle series comprises a new translation of Aristotle's Metaphysics Book [Theta], an introduction to the basic notions and problems around which the book is structured, and a detailed chapter-by-chapter critical commentary. Makin's aim throughout is to present Aristotle's text in as accessible a manner as possible, and to encourage and enable readers to engage critically with Aristotle's arguments. Metaphysics Book [Theta] is an extended discussion of the distinction between the actual and the potential, a distinction which is important both for Aristotle's own thought and for later philosophers. Aristotle starts by considering the relation between capacities and changes, and then expands his discussion to cover the notions of matter and substance, which are at the heart of his ontology. Among the topics covered in detail in the commentary are the distinctions between two-way and one-way capacities, and between rational and non-rational capacities; arguments against reductive views of possibility and impossibility; Aristotle's treatment of capacity identity and his account of the exercise of capacities; Aristotle's answer to the question 'what is it to be potentially such and such?'; his defence of the idea that actuality is prior in various ways to potentiality; and his brief comments on the evaluation of potentialities and actualities, the role of the actual-potential distinction in geometrical knowledge, and his treatment of truth and falsity."--BOOK JACKET.

"The 18th Symposium Aristotelicum, dedicated to the first Book of Aristotle's Metaphysics, was held in Leuven from 7th to 13th July 2008."--Pref.

Arthur Madigan presents a clear, accurate new translation of the third book (Beta) of Aristotle's Metaphysics, together with two related chapters from the eleventh book (Kappa). Madigan's accompanying commentary gives detailed guidance to these texts, in which Aristotle sets out what he takesto be the main problems of metaphysics or 'first philosophy' and assesses possible solutions to them.

Laura Castelli presents a new translation of the tenth book (Iota) of Aristotle's Metaphysics, together with a comprehensive commentary. Castelli's commentary helps readers to understand Aristotle's most systematic account of what it is for something to be one, what it is for something to be a unit of measurement, and what contraries are.
