On the Soul (De Anima) with Simplicius Commentary

Introduction, Philosophy, Aristotle, Soul

The study of the soul, or psyche The Greek word for soul, which also encompasses the principle of life and animation., stands as the cornerstone of Aristotelian philosophy. As the Stagirite A common epithet for Aristotle, referring to his birthplace, Stagira. suggests, to understand the soul is to understand the very nature of living beings. This inquiry must be approached not merely as a biological investigation, but as a metaphysical one, for the soul is the primary actuality of a natural body that has life in potentiality.

In the subsequent commentary, Simplicius A 6th-century Neoplatonist philosopher known for his extensive commentaries on Aristotle. masterfully reconciles the definition of the soul with the broader scope of physical motion. He elucidates how the soul acts as the "form" of the body, distinct from matter, yet inextricably linked to it in the operations of life, sensation, and intellect.

We shall proceed by examining the soul’s powers—nutritive, sensitive, and rational—and how these faculties define the hierarchy of existence from simple organisms to human beings. Through this, the reader will perceive that the soul is not an accidental property, but the essential cause of all that moves and breathes in the sublunary world.
