What… is this power which you think so very desirable? You should consider, poor earthly animals, what it is that you seem to have in your power. If you should see a mouse seizing power and lording it over the other mice, how you would laugh! But if you consider only his body, what is weaker than a man who can be killed by the bites of insects or by worms finding their way into him? For who can force any law upon man, except upon his body, or upon his fortune which is less than his body. You can never impose upon a free spirit, nor can you deprive a rationally self-possessed mind of its equanimity. Once, when a certain tyrant tried to torture a free man into betraying the partners of his conspiracy against the tyrant, the man bit off his tongue and spat it in the raging tyrant’s face. In this way the torments which the tyrant inflicted as the means of his cruelty, this wise man made the means of virtuous action. Indeed, what can any man do to another which another may not do to him? We recall that Busirus, who was accustomed to kill his guests, was himself slain by his guest, Hercules. Regulus had bound many of his African captives in chains; but before long he was himself chained by his captors. How slight is the power of a man who cannot prevent someone from doing to him what he does to others.
