Discourses: Book 1 18 : 5
Who, then, is the invincible man? He whom nothing that is outside the sphere of his moral purpose can dismay. I then proceed to consider the circumstances one by one, as I would do in the case of the athlete. "This fellow has won the first round. What, then, will he do in the second? What if it be scorching hot? And what will he do at Olympia?" It is the same way with the case under consideration. If you put a bit of silver coin in a man's way, he will despise it. Yes, but if you put a bit of a wench in his way, what then? Or if it be in the dark, what then? Or if you throw a bit of reputation in his way, what then? Or abuse, what then? Or praise, what then? Or death, what then? All these things he can overcome. What, then, if it be scorching hot—that is, what if he be drunk? What if he be melancholy-mad? What if asleep? The man who passes all these tests is what I mean by the invincible athlete.
