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.

It would be difficult to overstate the importance of Aristotle for a number of intellectual disciplines from Antiquity into the Middle Ages and beyond. However, Aristotle's philosophical ideas - both in themselves and as they were re-worked by later commentators - remain a subject of lively debate among contemporary philosophers and scholars. Form and Universal in Aristotle is a contribution to this controversy, offering the first full-length case against a conventional picture which presents Aristotle as holding an in re theory of universals. Chapters 1-3 argue that forms as such are not universals but particular and identical with particular things. Chapter 4 explains how Alexander of Aphrodisias filled some gaps in this theory and was followed by the Neoplatonic commentators. Excursuses at various points in the book suggest a bearing of this approach on other philosophical difficulties in Aristotle, such as the nature of thought, the extent of God's thought, and the functions of matter.

This book takes up the central themes of Aristotle's metaphysical theory and the various transformations they undergo prior to their full expresson in the Metaphysics.This book takes up the central themes of Aristotle's metaphysical theory and the various transformations they undergo prior to their full expresson in the Metaphysics.

The problem of being is central to Western metaphysics. Etched sharply in the verses of Parmenides, it took on distinctive colouring in Aristotle as the subject matter of a science expressly labelled 'theological.' For Aristotle, being could not be shared in generic fashion by other natures. As a nature it had to be found not in various species but in a primary instance only. The science specified by the primary nature was accordingly the one science that under the aspect of being treated universally of whatever is: it dealt with being qua being.

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.

The problem of universals is one of the crucial problems of contemporary philosophy in such areas as ontology, philosophy of language and epistemology. Are there general entities? Or is the world only populated by individuals, and universals are just concepts? What role does generality play in science? What is the relationship between general terms and the world? It is not always acknowledged that such questions have been at the centre of philosophical investigation since antiquity and that ancient philosophers have come up with a range of interesting and stimulating answers. This volume reconstructs the debate on universals in ancient thought, covering a period of about a thousand years, from the Sophists to the late Neoplatonists. Besides offering contributions on Plato, Aristotle, Hellenistic philosophers and Neoplatonism, the volume also deals with some lesser known aspects of Greek thought such as ancient medicine and mathematics.

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.

This is an attack on Aristotle showing that his misplaced drive toward the consistent application of his actualistic ontology (denying the reality of all potential things) resulted in many of his major theses being essentially vacuous.

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.
