text: Lo, these many years I have been condemning myself for imitating these men at the very time when I am arraigning them, and of wasting words on a subject that is perfectly clear. For who can doubt that, if heat is an evil, it is also an evil to be hot? Or that, if cold is an evil, it is an evil to be cold? Or that, if life is a Good, so is being alive? All such matters are on the outskirts of wisdom, not in wisdom itself. But our abiding-place should be in wisdom itself. Even though one takes a fancy to roam, wisdom has large and spacious retreats: we may investigate the nature of the gods, the fuel which feeds the constellations, or all the varied courses of the stars; we may speculate whether our affairs move in harmony with those of the stars, whether the impulse to motion comes from thence into the minds and bodies of all, and whether even these events which we call fortuitous are fettered by strict laws and nothing in this universe is unforeseen or unregulated in its revolutions. Such topics have nowadays been withdrawn from instruction in morals, but they uplift the mind and raise it to the dimensions of the subject which it discusses; the matters, however, of which I was speaking a while ago, wear away and wear down the mind, not (as you and yours maintain) whetting, but weakening it. And I ask you, are we to fritter away that necessary study which we owe to greater and better themes, in discussing a matter which may perhaps be wrong and is certainly of no avail? How will it profit me to know whether wisdom is one thing, and being wise another? How will it profit me to know that the one is, and the other is not, a Good? Suppose I take a chance, and gamble on this prayer: "Wisdom for you, and being wise for me!" We shall come out even.
