The Inner Citadel

From "The Inner Citadel: The Meditations of Marcus Aurelius" by Pierre Hadot:

"The Inner Citadel

Things Cannot Touch the Soul

Things cannot touch the soul.
They have no access to the soul.
They cannot produce our judgments.
They are outside of us.
They themselves know nothing, and by themselves they affirm nothing.
(Marcus Aurelius, Meditations, IV, 3, 10; V, 19; VI, 52; IX, 15)"
