What is the relation between time and change? Does time depend on the mind? Is the present always the same or is it always different? Aristotle tackles these questions in the Physics, and Time for Aristotle is the first book in English devoted to this discussion. Aristotle claims that time is not a kind of change, but that it is something dependent on change; he defines it as a kind of 'number of change'. Ursula Coope argues that what this means is that time is a kind of order (not, as is commonly supposed, a kind of measure). It is universal order within which all changes are related to each other. This interpretation enables Coope to explain two puzzling claims that Aristotle makes: that the now is like a moving thing, and that time depends for its existence on the mind. Brilliantly lucid in its explanation of this challenging section of the Physics, Time for Aristotle shows his discussion to be of enduring philosophical interest.

Aristotle's definition of time as 'a number of motion with respect to the before and after' has been branded as patently circular by commentators ranging from Simplicius to W. D. Ross. In this book Tony Roark presents an interpretation of the definition that renders it not only non-circular, but also worthy of serious philosophical scrutiny. He shows how Aristotle developed an account of the nature of time that is inspired by Plato while also thoroughly bound up with Aristotle's sophisticated analyses of motion and perception. When Aristotle's view is properly understood, Roark argues, it is immune to devastating objections against the possibility of temporal passage articulated by McTaggart and other 20th-century philosophers. Roark's novel and fascinating interpretation of Aristotle's temporal theory will appeal to those interested in Aristotle, ancient philosophy and the philosophy of time.

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.

This book is a contribution both to Aristotle studies and to the philosophy of nature, and not only offers a thorough text based account of time as modally potentiality in Aristotle’s account, but also clarifies the process of “actualizing time” as taking time and looks at the implications of conceiving a world without actual time. It speaks to the resurgence of interest in Aristotle’s natural philosophy and will become an important resource for anyone interested in Aristotle’s theory of time, of its relationship to Aristotle’s larger project in the Physics, and to time’s place in the broader scope of Aristotelian natural science. Graduate students and scholars researching in this area especially will find the authors arguments provocative, a welcome addition to other recent publications on Aristotle’s Treatise on Time. ​

Chapter 2 examines the notion of exteriority at work in Aristotle's theory of change. The time chapters of the Physics receive special attention in the book, anticipating the readings of Heidegger and Derrida in highlighting time and exteriority. Chapter 3 reads "Ousia and Gramme," in which Derrida reads Heidegger's reading of Aristotle's determination of Hegel's theory of time.

Science wasn't the only area that Aristotle examined. He founded one of the most important schools of the ancient world. He offered ideas on the best way to live. He developed a theory of drama that many modern screenwriters follow. He studied scores of different systems of government. Some of the conclusions from this study are reflected in the U.S. Constitution. This all-around genius had a huge impact on history.

Aristotle's Physics is one of the least studied "great books"--physics has come to mean something entirely different than Aristotle's inquiry into nature, and stereotyped Medieval interpretations have buried the original text. Sach's translation is really the only one that I know of that attempts to take the reader back to the text itself. -- Leon Cass, University of Chicago
