Aristotle’s theory of soul is grounded in hylomorphism, the idea that all living beings are composites of matter (hyle) and form (morphe).
The body is the matter, the potentiality.
The soul is the form, the actuality of a living body.
The soul is not a separate substance, but the essence that gives life and organization to the body.
The soul is the actuality of a body that has life potentially.” (De Anima, II.1)
