This examination of Aristotle's concept of natural substance and its implications for change, process, agency, teleology, mathematical continuity, and eternal motion illustrates the conceptual power of Aristotle's metaphysics of nature along with its scientific limitations and internal tensions.

A powerful and appealing explanatory scheme which succeeds on the whole in drawing together a great many seemingly disparate elements in the Physics' into a neat unitary structure.' Canadian Philosophical Reviews.

The Chain of Change is the first full-scale philosophical commentary devoted to Aristotle's Physics VII, in which Aristotle argues for the existence of a first, unmoved cosmic mover. This study systematically considers the major issues of the book, and argues for the fundamental importance of Physics VII in our understanding of Aristotelian cosmology and natural science. Physics VII is extant in two versions, and therefore poses special editorial problems. For this reason one of the features of Dr. Wardy's study is the provision of an improved text and translation in both versions. The author's comprehensive comparison of their merits, philosophical and philological, has a significant bearing on our understanding of the nature and evolution of the Aristotelian corpus. The second part of the book is devoted to critical examination of the argument, including one of the most elaborate and challenging in the entire Aristotelian corpus. Throughout, the author concentrates on those points where Aristotle diverges most sharply and provocatively from contemporary presumptions in philosophy and natural science.

In this book Helen S. Lang enters into the point of view of the ancient world to explain how they saw the world and to show what arguments were used by Aristotle to support this view. Lang demonstrates a new method for reading the texts of Aristotle by revealing a continuous line of argument running from the Physics to De Caelo. The author analyzes a group of arguments that are almost always treated in isolation from one another and reveals their elegance and coherence. She concludes by asking why these arguments remain interesting even though we now believe they are absolutely wrong and have been replaced by better ones. The author establishes that we must rethink our approach to Aristotle's physical science and Aristotelian texts. In so doing, her book will provoke debate and stimulate new thinking among philosophers, classicists, and historians of science.

"Book 3 of Aristotle's Physics primarily concerns two important concepts for his theory of nature: change and infinity. Change is important because, in Book 2, he has defined nature - the subject-matter of the Physics - as an internal source of change. Much of his discussion is dedicated to showing that the change occurs in the patient which undergoes it, not in the agent which causes it. Thus Book 3 is an important step in clearing the way for Book 8's claims for a divine mover who causes change but in whom no change occurs. The second half of Book 3 introduces Aristotle's doctrine of infinity as something which is always potential, never actual, never traversed and never multiplied. Here, as elsewhere, Philoponus the Christian turns Aristotle's own infinity arguments against the pagan Neoplatonist belief in a beginningless universe. Such a universe, Philoponus replies, would involve actual infinity of past years already traversed, and a multiple number of past days. The commentary also contains intimations of the doctrine of impetus - which has been regarded, in its medieval context, as a scientific revolution - as well as striking examples of Philoponus' use of thought experiments to establish philosophical and broadly scientific conclusions."--Bloomsbury Publishing.

This study is the first comprehensive analysis of the physical theory of the Islamic philosopher Avicenna (d. 1037). It seeks to understand his contribution against the developments within the preceding Greek and Arabic intellectual milieus, and to appreciate his philosophy as such by emphasising his independence as a critical and systematic thinker. Exploring Avicenna’s method of "teaching and learning," it investigates the implications of his account of the natural body as a three-dimensionally extended composite of matter and form, and examines his views on nature as a principle of motion and his analysis of its relation to soul. Moreover, it demonstrates how Avicenna defends the Aristotelian conception of place against the strident criticism of his predecessors, among other things, by disproving the existence of void and space. Finally, it sheds new light on Avicenna’s account of the essence and the existence of time. For the first time taking into account the entire range of Avicenna’s major writings, this study fills a gap in our understanding both of the history of natural philosophy in general and of the philosophy of Avicenna in particular. This monograph has been awarded the annual BRAIS – De Gruyter Prize (Kulturpreis Bayern) in the Study of Islam and the Muslim World and the Iran World Award for Book of the Year (2020).

This book considers the concepts that lay at the heart of natural philosophy and physics from the time of Aristotle until the fourteenth century. The first part presents Aristotelian ideas and the second part presents the interpretation of these ideas by Philoponus, Albertus Magnus, Thomas Aquinas, John Buridan, and Duns Scotus. Across the eight chapters, the problems and texts from Aristotle that set the stage for European natural philosophy as it was practiced from the thirteenth to the seventeenth centuries are considered first as they appear in Aristotle and then as they are reconsidered in the context of later interests. The study concludes with an anticipation of Newton and the sense in which Aristotle's physics had been transformed.
