The foregoing are a few of many instances in the history of Rome, and of a countless multitude in the history of the world, illustrating the truth, that the lodgement of arbitrary power, in the best human hands, is always a fearfully perilous experiment; that the mildest tempers, the most humane and benevolent dispositions, the most blameless and conscientious previous life, with the most rigorous habits of justice, are no security, that, in a moment of temptation, the possessors of such power will not make their subjects their victims; illustrating also the truth, that, while men may exhibit nothing but honor, honesty, mildness, justice, and generosity, in their intercourse with those of their own grade, or language, or nation, or hue, they may practice towards others, for whom they have contempt and aversion, the most revolting meanness, perpetrate robbery unceasingly, and inflict the severest privations, and the most barbarous cruelties.  But this is not all:  history is full of examples, showing not only the effects of arbitrary power on its victims, but its terrible reaction on those who exercise it; blunting their sympathies, and hardening to adamant their hearts toward them, at least, if not toward the human race generally.  This is shown in the fact, that almost every tyrant in the history of the world, has entered upon the exercise of absolute power with comparative moderation; multitudes of them with marked forbearance and mildness, and not a few with the most signal condescension, magnanimity, gentleness and compassion.  Among these last are included those who afterwards became the bloodiest monsters that ever cursed the earth.  Of the Roman Emperors, almost every one of whom perpetrated the most barbarous atrocities, Vitellius seems to have been the only one who cruelly exercised his power from the outset.  Most of the other emperors, sprung up into fiends in the hot-bed of arbitrary power.  If they had not been plied with its fiery stimulants, but had lived under the legal restraints of other men, instead of going to the grave under the curses of their generation, multitudes might have called them blessed.

The moderation which has generally distinguished absolute monarchs at the commencement of their reigns, was doubtless in some cases assumed from policy; in the greater number, however, as is manifest from their history, it has been the natural workings of minds held in check by previous associations, and not yet hardened into habits of cruelty, by being accustomed to the exercise of power without restraint.  But as those associations have weakened, and the wielding of uncontrolled sway has become a habit, like other evil doers, they have, in the expressive language of Scripture, ‘waxed worse and worse.’

For eighteen hundred years an involuntary shudder has run over the human race, at the mention of the name of Nero; yet, at the commencement of his reign, he burst into tears when called upon to sign the death-warrant of a criminal, and exclaimed, ’Oh, that I had never learned to write!’ His mildness and magnanimity won the affections of his subjects; and it was not till the poison of absolute power had worked within his nature for years, that it swelled him into a monster.
