TWO:It will be said, of course, that the practice of giving increased sentences where there have been previous convictions prevails all over the world and in all[90] states of civilisation. But in that very fact lies the strength of the argument against it. By the Roman law a third case of theft, however slight, exposed a man to death.[48] By the laws of St. Louis the man who stole a thing of trifling value lost an ear the first time, a foot the second, and was hung the third. By the criminal code of Sardinia in the fifteenth century, asses were condemned to lose one ear the first time they trespassed on a field not their masters, and their second ear for a second offence. But enough of such instances. The practice is undoubtedly universal; but so at one time were ordeals and tortures. May not, then, the practice be, like them, part and parcel of a crude state of law, such as was unavoidable in its emergence to better things, but such as it is worth some effort to escape from?In order that a punishment may attain its object, it is enough if the evil of the punishment exceeds the advantage of the crime, and in this excess of evil the certainty of punishment and the loss of the possible advantage from the crime ought to be considered as part; all beyond this is superfluous and consequently tyrannical. Men regulate their conduct by the reiterated impression of evils they know, not by reason of evils they ignore. Given two nations, in one of which, in the scale of punishments proportioned[167] to the scale of crimes, the severest penalty is perpetual servitude, and in the other the wheel; I say that the former will have as great a dread of its severest punishment as the latter will have; and if there be any reason for transporting to the former country the greater penalties of the other, the same reasoning will serve for increasing still more the penalties of this latter country, passing imperceptibly from the wheel to the slowest and most elaborate tortures, nay, even to the last refinements of that science which tyrants understand only too well.
