Power exercises a great influence over him who holds it. A head must be very well balanced not to be disturbed by it. The sort of dementia which took possession of the Roman emperors in the time of their world-wide rule, is a universal malady whose symptoms belong to all times. In every man there sleeps a tyrant, awaiting only a favorable occasion for waking. Now the tyrant is the worst enemy of authority, because he furnishes us its intolerable caricature, whence come a multitude of social complications, collisions and hatreds. Every man who says to those dependent on him: "Do this because it is my will and pleasure," does ill. There is within each one of us something that invites us to resist personal power, and this something is very respectable. For at bottom we are equal, and there is no one who has the right to exact obedience from me because he is he and I am I: if he does so, his command degrades me, and I have no right to suffer myself to be degraded. One must have lived in schools, in work-shops, in the army, in Government offices, he must have closely followed the relations between masters and servants, have observed a little everywhere where the supremacy of man exercises itself over man, to form any idea of the injury done by those who use power arrogantly. Of every free soul they make a slave soul, which is to say the soul of a rebel. And it appears that this result, with its social disaster, is most certain when he who commands is least removed from the station of him who obeys. The most implacable tyrant is the tyrant himself under authority. Foremen and overseers put more violence into their dealings than superintendents and employers. The corporal is generally harsher than the colonel. In certain families where madam has not much more education than her maid, the relations between them are those of the convict and his warder. And woe everywhere to him who falls into the hands of a subaltern drunk with his authority! We forget that the first duty of him who exercises power is humility. Haughtiness is not authority. It is not we who are the law; the law is over our heads. We only interpret it, but to make it valid in the eyes of others, we must first be subject to it ourselves. To command and to obey in the society of men, are after all but two forms of the same virtue--voluntary servitude. If you are not obeyed, it is generally because you have not yourself obeyed first.
