XVII. Aristotle says that “certain passions, if one makes a proper use of them, act as arms”: which would be true if, like weapons of war, they could be taken up or laid aside at the pleasure of their wielder. These arms, which Aristotle assigns to virtue, fight of their own accord, do not wait to be seized by the hand, and possess a man instead of being possessed by him. We have no need of external weapons, nature has equipped us sufficiently by giving us reason. She has bestowed this weapon upon us, which is strong, imperishable, and obedient to our will, not uncertain or capable of being turned against its master. Reason suffices by itself not merely to take thought for the future, but to manage our affairs:{22} 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. 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.
XVIII. Reason gives each side time to plead; moreover, she herself demands adjournment, that she may have sufficient scope for the discovery of the truth; whereas anger is in a hurry: reason wishes to give a just decision; anger wishes its decision to be thought just: reason looks no further than the matter in hand; anger is excited by empty matters hovering on the outskirts of the case: it is irritated by anything approaching to a confident demeanour, a loud voice, an unrestrained speech, dainty apparel, high-flown pleading, or popularity with the public. It often condemns a man because it dislikes his patron; it loves and maintains error even when truth is staring it in the face. It hates to be proved wrong, and thinks it more honourable to persevere in a mistaken line of conduct than to retract it. I remember Gnaeus Piso, a man who was free from many vices, yet of a perverse disposition, and one who mistook harshness for consistency. In his anger he ordered a soldier to be led off to execution because he had returned from furlough without his comrade, as though he must have murdered him if he could not show him. When the man asked for time for search, he would not grant it: the condemned man was brought outside the rampart, and was just offering his neck to the axe, when suddenly there appeared his comrade who was thought to be slain. Hereupon the centurion in charge of the execution bade the guardsman sheathe his sword, and led the condemned man back to Piso, to restore to him the innocence which Fortune had restored to the soldier. They were led into his presence by their fellow soldiers amid the great joy of the whole camp, embracing one another and accompanied by a vast crowd. Piso mounted the tribunal in a fury and ordered them both to be executed, both him who had not murdered and him who had not been slain. What could be more unworthy than this? Because one was proved to be innocent, two perished. Piso even added a third: for he actually ordered the centurion, who had brought back the condemned man, to be put to death. Three men were set up to die in the same place because one was innocent. O, how clever is anger at inventing reasons for its frenzy! “You,” it says, “I order to be executed, because you have been condemned to death: you, because you have been the cause of your comrade’s condemnation, and you, because when ordered to put him to death you disobeyed your general.” He discovered the means of charging them with three crimes, because he could find no crime in them.
XIX. Irascibility, I say, has this fault—it is loath to be ruled: it is angry with the truth itself, if it comes to light against its will: it assails those whom it has marked for its victims with shouting and riotous noise and gesticulation of the entire body, together with reproaches and curses. Not thus does reason act: but if it must be so, she silently and quietly wipes out whole households, destroys entire families of the enemies of the State, together with their wives and children, throws down their very dwellings, levels them with the ground, and roots out the names of those who are the foes of liberty. This she does without grinding her teeth or shaking her head, or doing anything unbecoming to a judge, whose countenance ought to be especially calm and composed at the time when he is pronouncing an important sentence. “What need is there,” asks Hieronymus, “for you to bite your own lips when you want to strike someone?” What would he have said, had he seen a proconsul leap down from the tribunal, snatch the fasces from the lictor, and tear his own clothes because those of others were not torn as fast as he wished.
