ONE: One of the greatest preventives of crimes is, not the cruelty of the punishments attached to them, but their infallibility, and consequently that watchfulness on the part of the magistrates and that inexorable severity on the part of the judge which, to be a useful virtue, must coincide with a mild system of laws. The certainty of a punishment, moderate though it be, will ever make a stronger impression than the fear of another, more terrible, perhaps, but associated with the hope of impunity; for even the least evils when certain always terrify mens minds, and hope, that gift of heaven, which often makes up to us for everything, always throws into the distance the idea of greater evils, especially when its force is increased by impunity, which avarice and weakness so often grant.
TWO:
ONE:It is, however, probable that the frequency of any crime bears little or no relation to the punishment affixed to it. Every criminal begins a new career, in which he thinks less of the nature of his punishment than of his chances of eluding it. Neither tradition nor example count with him for much in his balance of the chances in his own favour. The law can never be so certain in its execution as it is uncertain in its application, and it is the examples of impunity, not of punishment, to which men turn when they violate the law. So that whether the punishment for murder be an excruciating death, as in ancient Rome, or a mere fine, as in ancient England, the motives for escape are always the same, the means to effect it are always the same, and the belief in his power to effect it is correspondingly powerful in every criminal guilty of homicide.It is remarkable that a book which has done more for law reform than any other before or since should have been written by a man who was not a lawyer by profession, who was totally unversed in legal practice, and who was only twenty-six when he attacked a system of law which had on its side all authority, living and dead. Hume was not twenty-seven when[4] he published his Treatise on Human Nature, nor was Berkeley more than twenty-six when he published his Principles of Human Knowledge. The similar precocity displayed by Beccaria is suggestive, therefore, of the inquiry, how far the greatest revolutions in the thoughts or customs of the world have been due to writers under thirty years of age.
TWO:As a matter of fact the law affords a very clear[81] proof, that its real purpose is to administer retributive justice and that punishment has no end beyond itself, by its careful apportionment of punishment to crime, by its invariable adjustment between the evil a man has done and the evil it deals out to him in return. For what purpose punish offences according to a certain scale, for what purpose stay to measure their gravity, if merely the prevention of crime is the object of punishment? Why punish a slight theft with a few months imprisonment and a burglary with as many years? The slight theft, as easier to commit, as more tempting accordingly, should surely have a harder penalty affixed to it than a crime which, as it is more difficult, is also less probable and less in need of strong counter-inducements to restrain it. That the law never reasons in this way is because it weighs offences according to their different degrees of criminality, or, in other words, because it feels that the fair retaliation for the burglary is not a fair retaliation for the theft.
