The problem of the One and the Many is a problem essentially Platonic. Characteristically Platonic is the saying of Socrates in the Phaedrus: “If I find any man who is able to see a ‘One and Many’ in nature, him I follow, and ‘walk in his footsteps as if he were a god.’” The problem of the One and the Many may indeed be said to be the point around which Plato's deepest concerns center. It occurs in most of his dialogues. It appears in different formulations, and it receives a variety of emphasis. It is certainly at the root of his morals. “Not life, but a good life, is to be chiefly valued,” is Plato's fundamental teaching. And the good life is a life of law, order, justice. The diverse elements of the soul must be set in order; they must submit to one organizing principle; they must become a well-ordered unity.
