This book investigates what change is, according to Aristotle, and how it affects his conception of being. Mark Sentesy argues that the analysis of change leads Aristotle to develop first-order metaphysical concepts such as matter, potency, actuality, sources of being, epigenesis, and teleology. He shows that Aristotle's distinctive ontological claim-that being is inescapably diverse in kind-is anchored in his argument for the existence of change.
Aristotle may be the only thinker to propose a noncircular definition of change. With his landmark argument that change did, in fact, exist, Aristotle challenged established assumptions about what it is and developed a set of conceptual frameworks that continue to provide insight into the nature of reality. This groundbreaking work on change, however, has long been interpreted through a Platonist view of change as unreal. By offering a comprehensive reexamination of Aristotle's pivotal arguments, and establishing his positive ontological conception of change, Sentesy makes a significant contribution to scholarship on Aristotle, ancient philosophy, the history and philosophy of science, and metaphysics.
