what, then, can be more foolish than for reason to beg anger for protection, that is, for what is certain to beg of what is uncertain? what is trustworthy of what is faithless? what is whole of what is sick? What, indeed? since reason is far more powerful by itself even in performing those operations in which the help of anger seems especially needful: for when reason has decided that a particular thing should be done, she perseveres in doing it; not being able to find anything better than herself to exchange with. She, therefore, abides by her purpose when it has once been formed; whereas anger is often overcome by pity: for it possesses no firm strength, but merely swells like an empty bladder, and makes a violent beginning, just like the winds which rise from the earth and are caused by rivers and marshes, which blow furiously without any continuance: anger begins with a mighty rush, and then falls away, becoming fatigued too soon: that which but lately thought of nothing but cruelty and novel forms of torture, is become quite softened and gentle when the time comes for punishment to be inflicted.
