Passion soon cools, whereas reason is always consistent: yet even in cases where anger has continued to burn, it often happens that although there may be many who deserve to die, yet after the death of two or three it ceases to slay. Its first onset is fierce, just as the teeth of snakes when first roused from their lair are venomous, but become harmless after repeated bites have exhausted their poison. Consequently those who are equally guilty are not equally punished, and often he who has done less is punished more, because he fell in the way of anger when it was fresher. It is altogether irregular; at one time it runs into undue excess, at another it falls short of its duty: for it indulges its own feelings and gives sentence according to its caprices, will not listen to evidence, allows the defence no opportunity of being heard, clings to what it has wrongly assumed, and will not suffer its opinion to be wrested from it, even when it is a mistaken one.
