Context

“The excess can be manifested in all the points that have been named (for one can be angry with the wrong persons, at the wrong things, more than is right, too quickly, or too long) ; yet all are not found in the same person. Indeed they could not; for evil destroys even itself, and if it is complete becomes unbearable. Now hot-tempered people get angry quickly and with the wrong persons and at the wrong things and more than is right, but their anger ceases quickly-which is the best point about them. This happens to them because they do not restrain their anger but retaliate openly owing to their quickness of temper, and then their anger ceases.” source
