"De Anima" is a foundational philosophical treatise that explores the concept of the soul and its relation to the body. The work delves into the nature of life itself, categorizing different kinds of souls possessed by different kinds of living things, such as plants, animals, and humans. It discusses the faculties of the soul, including the nutritive, perceptive, and intellectual aspects, and investigates their functions and interactions. The treatise also examines issues of perception, cognition, and memory, arguing that the soul is the principle of life and the source of all vital functions, ultimately aiming to define the essence of life and the basis of all living activities.
