This book is Aristotle's seminal treatise, "De Anima". Within this treatise Aristotle explores the nature of living things, discussing what types of souls certain living things possess by assessing the difference in their operations. A fascinating monograph by one of the greatest minds to have ever lived, Aristotle's "De Anima" is highly recommended for students of philosophy, and would make for a great addition to any bookshelf. Aristotle (384-322 BC) was a seminal Greek scientist and philosopher. Many vintage books such as this are becoming increasingly rare and expensive. It is with this in mind that we are republishing this volume now in an affordable, modern, high-quality edition complete with a specially commissioned new biography of the author.
