text: But just as we take on faith such estimates of values, so let us take on the faith of the people this truth, that nothing is more honourable than a grateful heart. This phrase will be echoed by all cities, and by all races, even those from savage countries. Upon this point good and bad will agree. Some praise pleasure, some prefer toil; some say that pain is the greatest of evils, some say it is no evil at all; some will include riches in the Supreme Good, others will say that their discovery meant harm to the human race, and that none is richer than he to whom Fortune has found nothing to give. Amid all this diversity of opinion all men will yet with one voice, as the saying is, vote "aye" to the proposition that thanks should be returned to those who have deserved well of us. On this question the common herd, rebellious as they are, will all agree, but at present we keep paying back injuries instead of benefits, and the primary reason why a man is ungrateful is that he has found it impossible to be grateful enough. Our madness has gone to such lengths that it is a very dangerous thing to confer great benefits upon a person; for just because he thinks it shameful not to repay, so he would have none left alive whom he should repay. "Keep for yourself what you have received; I do not ask it back; I do not demand it. Let it be safe to have conferred a favour." There is no worse hatred than that which springs from shame at the desecration of a benefit. Farewell.
