On the soul

On the Soul (De Anima), written by the ancient Greek philosopher Aristotle, stands as one of the most influential works in Western philosophy and psychology. In this foundational treatise, Aristotle investigates the nature of the soul, its relationship to the body, and its fundamental capacities, including perception, intellect, and motion. Departing from more mystical interpretations, he defines the soul as the form and vital principle of living beings, inseparable from biological life itself.
