Examines Aristotle's doctrine of hylomorphism and its importance for understanding the process by which substances come into being.

Space, Time, Matter, and Form collects ten of David Bostock's essays on themes from Aristotle's Physics, four of them published here for the first time. The first five papers look at issues raised in the first two books of the Physics, centred on notions of matter and form, and the idea of substance as what persists through change. They also range over other of Aristotle's scientific works, such as his biology and psychology and the account of change in his De Generatione et Corruptione. The volume's remaining essays examine themes in later books of the Physics, including infinity, place, time, and continuity. Bostock argues that Aristotle's views on these topics are of real interest in their own right, independent of his notions of substance, form, and matter; they also raise some pressing problems of interpretation, which these essays seek to resolve.

Adriel M. Trott challenges the wholesale acceptance of the view that nature operates in Aristotle's work on a craft model, which implies that matter has no power of its own. Instead, she argues for a robust sense of matter in Aristotle in response to feminist critiques. She finds resources for thinking the female's contribution - and the female - on its own terms and not as the contrary to form, or the male.

Explores different applications of Aristotle's hypothesis on the components of form, matter and pyschological states.

Mark Eli Kalderon presents an original study in the philosophy of perception written in the medium of historiography. He considers the phenomenology and metaphysics of sensory presentation through the examination of an ancient aporia. Specifically, he argues that a puzzle about perception at a distance is behind Empedocles' theory of vision. Empedocles conceives of perception as a mode of material assimilation, but this raises a puzzle about color vision, since color vision seems to present colors that inhere in distant objects. But if the colors inhere in distant objects how can they be taken in by the organ of sight and so be palpable to sense? Aristotle purports to resolve this puzzle in his definition of perception as the assimilation of sensible form without the matter of the perceived particular. Aristotle explicitly criticizes Empedocles, though he is keen to retain the idea that perception is a mode of assimilation, if not a material mode. Aristotle's notorious definition has long puzzled commentators. Kalderon shows how, read in light of Empedoclean puzzlement about the sensory presentation of remote objects, Aristotle's definition of perception can be better understood. Moreover, when so read, the resulting conception of perception is both attractive and defensible.

This book explores a fundamental tension in Aristotle's metaphysics: how can an entity such as a living organisma composite generated through the imposition of form on preexisting matterhave the conceptual unity that Aristotle demands of primary substances? Mary Louise Gill bases her treatment of the problem of unity, and of Aristotle's solution, on a fresh interpretation of the relation between matter and form. Challenging the traditional understanding of Aristotelian matter, she argues that material substances are subverted by matter and maintained by form that controls the matter to serve a positive end. The unity of material substances thus involves a dynamic relation between resistant materials and directive ends. Aristotle on Substance offers both a general account of matter, form, and substantial unity and a specific assessment of particular Aristotelian arguments. At every point, Gill engages Aristotle on his own philosophical ground through the detailed analysis of central, and often controversial, texts from the Metaphysics, Physics, On Generation and Corruption, De Anima, De Caelo, and the biological works. The result is a coherent, firmly grounded rethinking of Aristotle's central metaphysical concepts and of his struggle toward a fully consistent theory of material substances.

Christian Pfeiffer explores an important, but neglected topic in Aristotle's theoretical philosophy: the theory of bodies. A body is a three-dimensionally extended and continuous magnitude bounded by surfaces. This notion is distinct from the notion of a perceptible or physical substance. Substances have bodies, that is to say, they are extended, their parts are continuous with each other and they have boundaries, which demarcate them from their surroundings. Pfeiffer argues that body, thus understood, has a pivotal role in Aristotle's natural philosophy. A theory of body is a presupposed in, e.g., Aristotle's account of the infinite, place, or action and passion, because their being bodies explains why things have a location or how they can act upon each other. The notion of body can be ranked among the central concepts for natural science which are discussed in Physics III-IV. The book is the first comprehensive and rigorous account of the features substances have in virtue of being bodies. It provides an analysis of the concept of three-dimensional magnitude and related notions like boundary, extension, contact, continuity, often comparing it to modern conceptions of it. Both the structural features and the ontological status of body is discussed. This makes it significant for scholars working on contemporary metaphysics and mereology because the concept of a material object is intimately tied to its spatial or topological properties.

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.

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.

The idea that some parts of reality are fundamental and others derivative was an important one in Aristotle's philosophical system, and is now again of great current interest in philosophy. Michail Peramatzis presents a new account of priority relations in Aristotle's metaphysics, and draws out their continuing philosophical significance.
