This is apparently the last treatise Plotinus wrote before his death. It is a sort of addendum to 1.4 (46), ‘On Happiness’, focusing on the metaphysical foundation of his ethical philosophy. Here he insists, against Aristotle, that this foundation must be an absolutely transcendent Idea of the Good.
§1. The primacy of the Good and its priority to the Unmoved Mover of Aristotle.
§2. The way in which all things share in the Good.
§3. The problem of evil in relation to living and dying.
