P71: Only free men are very thankful to one another.

Dem.: Only free men are very useful to one another, are joined to one another by the greatest necessity of friendship (by P35 and P35 C1), and strive to benefit one another with equal eagerness for love (by P37). So (by Def. Aff. XXXIV) only free men are very thankful to one another, q.e.d.

Schol.: The thankfulness which men are led by blind Desire to display toward one another is for the most part a business transaction or an entrapment, rather than thankfulness.

Again, ingratitude is not an affect. Nevertheless, ingratitude is dishonorable because it generally indicates that the man is affected with too much Hate, Anger, Pride, or Greed, etc.

For one who, out of foolishness, does not know how to reckon one gift against another, is not ungrateful; much less one who is not moved by the gifts of a courtesan to assist her lust,36 nor by those of a thief to conceal his thefts, nor by those of anyone else like that. On the contrary, he shows firmness of mind who does not allow any gifts to corrupt him, to his or to the general ruin.
