Frank A. Lewis presents a closely argued exposition of Metaphysics Zeta—one of Aristotle's most dense and controversial texts. It is commonly understood to contain Aristotle's deepest thoughts on the definition of substance and surrounding metaphysical issues. But people have increasingly come to recognize how little Aristotle says in Zeta about his own theory of (Aristotelian) form and matter. Instead, he spends the bulk of the book examining 'received opinions', often as filtered through his own Organon, but including above all the views of Plato, who is at times friend, and at times foe. For much of the time, we are left to reconstruct Aristotle's finished views, subject to the constraint that they survive the critique he directs in Zeta at the philosophical tradition. In this book, Lewis argues that in giving his actual conclusion to Zeta in its final chapter, 17, Aristotle drops his earlier, largely critical engagement with received views, and turns approvingly to his own Posterior Analytics. The result is a causal view of (primary) substance, representing the property of being a (primary) substance (or the substance of a thing) as, in modern dress, the second-order functional property of (Aristotelian) forms, that they be the cause of being for different compound material substances. The property of being the cause of being for a thing is a role property, and it is realized in different forms and the sets of causal powers associated with them, matching the variety of things that have a form as their substance. Meanwhile, the failure of previous attempts at definition in earlier chapters leaves Aristotle's own definition standing as the 'best explanation' for the views proprietary to the theory of form and matter. The point that (Aristotelian) forms are the primary substances is not the main conclusion to Zeta, but rather a result his definition must give, if the definition is to be acceptable.

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. .

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.

Michael J. Loux here presents a fresh reading of two of the most important books of the Metaphysics, Books Z and H, in which Aristotle presents his mature theory of primary substances (ousiai). Focusing on the interplay of Aristotle's early and late views, Loux maintans that the later concept of ousia should be understood in terms of a theory of predication that carries interesting implications for contemporary metaphysics. Loux argues that in his first attempt in identifying ousiai in the Categories, Aristotle encountered a set of ontological problems which he wrestled with again in Metaphysics Z and H. In the Categories, where the primary realities are basic subjects of predication construed in essentialist terms as things falling under natural kinds, familiar particulars are the primary ousiai. In subsequent works, Aristotle holds that since familiar particulars come into being and pass away, they must be composites of matter and form; and in Metaphysics Z and H, he explores the implications of this insight for the search for ousia. Maintaining that the substantial forms of familiar particulars are the primary ousiai, the later Aristotle interprets forms as predicable universals rather than as particulars, each uniquely possessed by a single object.

The Metaphysics presents Aristotle's mature rejection of both the Platonic theory that what we perceive is just a pale reflection of reality and the hardheaded view that all processes are ultimately material. He argued instead that the reality or substance of things lies in their concrete forms, and in so doing he probed some of the deepest questions of philosophy: What is existence? How is change possible? And are there certain things that must exist for anything else to exist at all? The seminal notions discussed in The Metaphysics - of 'substance' and associated concepts of matter and form, essence and accident, potentiality and actuality - have had a profound and enduring influence, and laid the foundations for one of the central branches of Western philosophy.

Aristotle's views on the fundamental nature of reality are usually taken to be inconsistent. Two sources for these views are Categories and the central books of Metaphysics. This text argues that he is engaged in different projects in these books.

"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.

Aristotles' 'Metaphysics' is one of the most important texts in Ancient Philosophy. This GuideBook looks at the Metaphysics thematically and takes the student through the main arguments found in the text. The book introduces and assesses Aristotle's life and the background to the Metaphysics, the ideas and text of the Metaphysics and Aristotle's philosophical legacy.
