The De Anima (On the Soul) is the first and most general of Aristotle’s biological works and as such is the most important work in the study of nature after the Physics of Aristotle. It is presupposed to Aristotle’s Sense and the Sensible, Memory and Reminiscence, and his many other biological works. 

In this text, Aristotle discusses his predecessors’ views of life, defines the principle of life (“soul”), discusses the principle sorts of living things (plants, animals, and human beings), and analyzes the chief activities of each sort of life. In the case of rational life, he shows that the ability to think implies an immaterial aspect to the human soul.

The De Anima is necessary not only to the study of biology, but also advances the understanding of metaphysics, of ethics and of politics, and even of logic, insofar as logic directs the acts of the human mind.

Like Coughlin’s translation of Aristotle’s Physics (also published by St. Augustine Press), this translation attempts to be literal and concrete. The edition includes the translation, introduction, glossary, index, and explanatory notes.

The William of Moerbeke Translation Series, under the general editorship of Stuart D. Warner, is devoted to publishing translations of important works - ancient, medieval, and modern - regardless of the original language, in every area of scholarly endeavor, including philosophy, political science, theology, literature, history, economics, and law. The aim of the series is to bring the reader as close as possible to the letter and spirit of the original work. Each volume will contain a scholarly introduction and notes. We welcome all inquiries and suggestions. Physics, Or Natural Healing is the first volume of this series.
