Book 5.14
Cleanthes speaks more impetuously than this. "Granted," says he, "that what he received was not a benefit, yet he is ungrateful, because he would not have returned a benefit if he had received one." So he who carries deadly weapons and has intentions of robbing and murdering, is a brigand even before he has dipped his hands in blood; his wickedness consists and is shown in action, but does not begin thereby. Men are punished for sacrilege, although no one's hands can reach to the gods. "How," asks our opponent, "can any one be ungrateful to a bad man, since a bad man cannot bestow a benefit?" In the same way, I answer, because that which he received was not a benefit, but was called one; if any one receives from a bad man any of those things which are valued by the ignorant, and of which bad men often possess great store, it becomes his duty to make a return in the same kind, and to give back as though they were truly good those things which he received as though they were truly good. A man is said to be in debt, whether he owes gold pieces or leather marked with a state stamp, such as the Lacedaemonians used, which passes for coined money. Pay your debts in that kind in which you incurred them. You have nothing to do with the definition of benefits, or with the question whether so great and noble a name ought to be degraded by applying it to such vulgar and mean matters as these, nor do we seek for truth that we may use it to the disadvantage of others; do you adjust your minds to the semblance of truth, and while you are learning what is really honourable, respect everything to which the name of honour is applied.
