18 And the forms of wisdom are prudence, and justice, and manliness, and temperance.
19 The leading one of these is prudence; by whose means, indeed, it is that reasoning bears rule over the passions.
20 Of the passions, pleasure and pain are the two most comprehensive; and they also by nature refer to the soul.
21 And there are many attendant affections surrounding pleasure and pain.
22 Before pleasure is lust; and after pleasure, joy.
23 And before pain is fear; and after pain is sorrow.
24 Wrath is an affection, common to pleasure and to pain, if any one will pay attention when it comes upon him.
