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)
