ONE:For instance, the injury to the public is no greater the hundredth time a man steals a rabbit than it is the first. The public may be interested in the prevention of poaching, but it is not interested in the person of the poacher, nor in the number of times he may have broken the law. The law claims to be impersonalto treat offences as they affect the State, not as they affect individuals; to act mechanically, coldly, and dispassionately. It has, therefore, simply to deal with the amount of injury done by each specific offence, and to affix to it its specific penalty, regardless of all matters of moral antecedents. The repetition of an offence may make its immorality the greater, but its[88] criminality remains the same, and this only is within the province of the law.But the man who sees in prospect a great number of years, or perhaps the whole of his life, to be passed in servitude and suffering before the eyes of fellow-citizens with whom he is living in freedom and friendship, the slave of those laws which had once protected him, makes a useful comparison of all these circumstances with the uncertain result of his crimes and with the shortness of the time for which he would enjoy their fruits. The ever present example of those whom he actually sees the victims of their own imprudence, impresses him much more strongly than the sight of a punishment which hardens rather than corrects him.
THREE: A contradiction between the laws and the natural feelings of mankind arises from the oaths which are required of an accused, to the effect that he will be a truthful man when it is his greatest interest to be false; as if a man could really swear to contribute to his own destruction, or as if religion would not be silent with most men when their interest spoke on the other side. The experience of all ages has shown that men have abused religion more than any other of the precious gifts of heaven; and for what reason should criminals respect it, when men esteemed as the wisest have often violated it? Too weak, because too far removed from the senses, are[147] for the mass of people the motives which religion opposes to the tumult of fear and the love of life. The affairs of heaven are conducted by laws absolutely different from those which govern human affairs; so why compromise those by these? Why place men in the terrible dilemma of either sinning against God or concurring in their own ruin? The law, in fact, which enforces such an oath commands a man either to be a bad Christian or to be a martyr. The oath becomes gradually a mere formality, thus destroying the force of religious feelings, which for the majority of men are the only pledge of their honesty. How useless oaths are has been shown by experience, for every judge will bear me out when I say that no oath has ever yet made any criminal speak the truth; and the same thing is shown by reason, which declares all laws to be useless, and consequently injurious, which are opposed to the natural sentiments of man. Such laws incur the same fate as dams placed directly in the main stream of a river: either they are immediately thrown down and overwhelmed, or a whirlpool formed by themselves corrodes and undermines them imperceptibly.
THREE:But undoubtedly punishment, although in its origin and present intention vindictive, must exercise a certain preventive force against crime, and this preventive force can scarcely be estimated, for that which is prevented is, of course, not seen. But the efficiency of punishment as a deterrent is proportioned to its certainty, and there is a large element of uncertainty that can never be eliminated. For every malefactor there are two hopes: first, that he may escape detection or apprehension; secondly, that he may escape conviction. That his hopes of impunity are not without reason greater than his fears of punishment the following facts attest.In view of these principles it will appear strange (to anyone who does not reflect, that reason has, so to speak, never yet legislated for a nation), that it is just the most atrocious crimes or the most secret and chimerical onesthat is, those of the least probabilitywhich are proved by conjectures or by the weakest and most equivocal proofs: as if it were the interest of the laws and of the judge, not to search for the truth, but to find out the crime; as if the danger of condemning an innocent man were not so much the greater, the greater the probability of his innocence over that of his guilt.
