For Aristotle, the soul is not an immaterial entity trapped within a body, as some of Plato’s writings might suggest. Instead, he defined the soul as the "actuality of a body that has life," serving as the essential form or organizing principle of an organic body.12

Key aspects of this relationship include:

Form and Matter: Aristotle viewed a living substance as a composite of matter and form. The soul is the form of the body, much like the impression of a seal is inseparable from the wax upon which it is impressed.1
Functional Unity: The soul is the source of an organism's powers, including nutrition, growth, reproduction, perception, and cognition. It is not a distinct agent acting upon the body but is defined by its relationship to the body’s specific structure and functions.21
Hierarchy of Faculties: Aristotle organized souls into a hierarchy based on their functions: the vegetative soul (plants), the sensitive soul (animals), and the rational soul (humans).1
The Intellect: While Aristotle’s biological view emphasizes the soul as the body's form, he also introduced a distinction regarding the "active intellect," which some interpretations suggest may be separable from the body, creating a tension between his biological and transcendent views.31
