What then, am I such a one? How should I? Indeed, are you such a one as to be able to hear the truth? I wish you were. But, however, since I am condemned to wear a grey beard and a cloak, and you come to me as to a philosopher, I will not treat you cruelly, nor as if I despaired of you, but will ask you—Whom is it, young man, whom you would render beautiful? Know first who you are, and then adorn yourself accordingly. You are a man ; that is, a mortal animal, capable of a rational use of the appearances of things. And what is this rational use? A perfect conformity to nature. What have you then particularly excellent? Is it the animal part? No. The mortal? No. That which is capable of the use of the appearances of things? No. The excellence lies in the rational part. Adorn and beautify this, but leave your hair to him who formed it, as he thought good.
