Fragment 12

There are certain persons who exhibit their high spirit rather gently,²⁰ and in a sort of passionless manner do everything that even those who are swept away by their anger do. We must be on our guard, therefore, against the error of these persons, as something much worse than violent anger. For those who give way to violent anger are soon sated with their revenge, but the others prolong it like men who have a light fever.
