Book 3.30
How much better is it to observe how trifling, how inoffensive are the first beginnings of anger? You will see that men are subject to the same influences as dumb animals: we are put out by trumpery, futile matters. Bulls are excited by red colour, the asp raises its head at a shadow, bears or lions are irritated at the shaking of a rag, and all creatures who are naturally fierce and wild are alarmed at trifles. The same thing befalls men both of restless and of sluggish disposition; they are seized by suspicions, sometimes to such an extent that they call slight benefits injuries: and these form the most common and certainly the most bitter subject for anger: for we become angry with our dearest friends for having bestowed less upon us than we expected, and less than others have received from them: yet there is a remedy at hand for both these grievances. Has he favoured our rival more than ourselves? then let us enjoy what we have without making any comparisons. A man will never be well off to whom it is a torture to see any one better off than himself. Have I less than I hoped for? well, perhaps I hoped for more than I ought. This it is against which we ought to be especially on our guard: from hence arises the most destructive anger, sparing nothing, not even the holiest. The Emperor Julius was not stabbed by so many enemies as by friends whose insatiable hopes he had not satisfied. He was willing enough to do so, for no one ever made a more generous use of victory, of whose fruits he kept nothing for himself save the power of distributing them; but how could he glut such unconscionable appetites, when each man coveted as much as any one man could possess? This was why he saw his fellow-soldiers standing round his chair with drawn swords, Tillius Cimber, though he had a short time before been the keenest defender of his party, and others who only became Pompeians after Pompeius was dead. This it is which has turned the arms of kings against them, and made their trustiest followers meditate the death of him for whom and before whom they once would have been glad to die.
