On such occasions, it is not thanks to reason that anger is stilled, but owing to an untrustworthy and fleeting truce between the passions.
In the next place, anger has nothing useful in itself, and does not rouse up the mind to warlike deeds: for a virtue, being self-sufficient, never needs the assistance of a vice: whenever it needs an impetuous effort, it does not become angry, but rises to the occasion, and excites or soothes itself as far as it deems requisite, just as the machines which hurl darts may be twisted to a greater or lesser degree of tension at the manager’s pleasure. “Anger,” says Aristotle, “is necessary, nor can any fight be won without it, unless it fills the mind, and kindles up the spirit. It must, however, be made use of, not as a general, but as a soldier.” Now this is untrue; for if it listens to reason and follows whither reason leads, it is no longer anger, whose characteristic is obstinacy: if, again, it is disobedient and will not be quiet when ordered, but is carried away by its own willful and headstrong spirit, it is then as useless an aid to the mind as a soldier who disregards the sounding of the retreat would be to a general.
