Why, it would be ridiculous, as Plato Republic, 430 e. says, for a man to say that he is now better than himself and again worse than himself, and sometimes master of himself and sometimes not.

For how is it possible for the same man to be both better and worse than himself, or to be master of himself and at the same time be mastered, if in some way or other each man were not by nature double and had not both the worse and the better within himself? This being the case, he who holds the worse in subjection to the better is Iself-controlled and better than himself, but he who permits the better part to follow and be in subjection to the intemperate and irrational part of his soul is called worse than himself and incontinent and in a state contrary to Nature.
