Why destroy aretê? And no sooner had he asked the question than the answer came to him. Plato hadn't tried to destroy aretê. He had encapsulated it; made a permanent, fixed Idea out of it; had converted it to a rigid, immobile Immortal Truth. He made aretê the Good, the highest form, the highest Idea of all. It was subordinate only to Truth itself, in a synthesis of all that had gone before.
