De Anima

Aristotle's De Anima (On the Soul) is a seminal work in the history of philosophy and psychology.

It explores the nature of the soul, its relationship to the body, and its various functions.

Aristotle rejects Plato's theory of the soul as a separate, immortal entity, arguing instead that the soul is the form or essence of a living organism.

He distinguishes between different types of souls, from the vegetative soul of plants to the rational soul of humans.

De Anima significantly influenced subsequent philosophical and scientific thinking about the mind and consciousness, shaping discussions on the nature of life and intelligence.
