1 The goodwill, which men who are led by blind desire 2 have for one another, is generally a bargaining or enticement, 3 rather than pure goodwill. Moreover, ingratitude is not an 4 emotion. Yet it is base, inasmuch as it generally shows, that a 5 man is affected by excessive hatred, anger, pride, avarice, &c. 6 He who, by reason of his folly, knows not how to return benefits, 7 is not ungrateful, much less he who is not gained over by the 8 gifts of a courtesan to serve her lust, or by a thief to conceal 9 his thefts, or by any similar persons. Contrariwise, such an one 10 shows a constant mind, inasmuch as he cannot by any gifts be 11 corrupted, to his own or the general hurt. 12 13
