THREE:Would you prevent crimes, then cause the laws to be clear and simple, bring the whole force of a nation to bear on their defence, and suffer no part of it to be busied in overthrowing them. Make the laws to favour not so much classes of men as men themselves. Cause men to fear the laws and the laws alone. Salutary is the fear of the law, but fatal and fertile in crime is the fear of one man of another. Men as slaves are more sensual, more immoral, more cruel than free men; and, whilst the latter give their minds to the sciences or to the interests of their country, setting great objects before them as their model, the former, contented with the passing day, seek in the excitement of libertinage a distraction from the nothingness of their existence, and, accustomed to an uncertainty of result in everything, they look upon the result of their crimes as uncertain too, and so decide in favour of the passion that tempts them. If uncertainty of the laws affects a nation, rendered indolent by its climate, its indolence and stupidity is thereby maintained and increased; if it affects a nation, which though fond of pleasure is also full of energy, it wastes that energy in a number of petty cabals and intrigues, which spread distrust in every heart, and make treachery and dissimulation the foundation of prudence; if, again, it affects a[245] courageous and brave nation, the uncertainty is ultimately destroyed, after many oscillations from liberty to servitude, and from servitude back again to liberty.I speak of probability in connection with crimes, which, to deserve punishment, ought to be proved. But the paradox is only apparent, if one reflects that, strictly speaking, moral certainty is only a probability, but a probability which is called certainty, because every sensible person necessarily assents to it, by a force of habit which arises from the necessity of acting, and which is prior to all speculation. The certainty requisite for certifying that a man is a criminal is, therefore, the same that determines everyone in the most important actions of his life. The proofs of a crime may be divided into ��perfect�� and ��imperfect,�� the former being of such a[136] nature as exclude the possibility of a man��s innocence, and the latter such as fall short of this certainty. Of the first kind one proof alone is sufficient for condemnation; of the second, or imperfect kind, as many are necessary as suffice to make a single perfect proof; that is to say, when, though each proof taken separately does not exclude the possibility of innocence, yet their convergence on the same point makes such innocence impossible. But let it be noted that imperfect proofs, from which an accused has it in his power to justify himself and declines to do so, become perfect. This moral certainty of proofs, however, is easier to feel than to define with exactitude: for which reason I think that the best law is one which attaches to the chief judge assessors, taken by lot, not by selection, there being in this case more safety in the ignorance which judges by sentiment than in the knowledge which judges by opinion. Where the laws are clear and precise, the function of a judge consists solely in the certification of fact. If for searching out the proofs of a crime ability and cleverness are required, and if in the presentation of the result clearness and precision are essential, all that is required to judge of the result is simple and common good sense, a faculty which is less fallacious than the learning of a judge, accustomed as he is to wish to find men guilty and to reduce everything to an artificial system borrowed from his studies. Happy the nation where the[137] laws are not a science! It is a most useful law that everyone shall be judged by his equals, because where a citizen��s liberty and fortune are at stake those sentiments which inequality inspires should have no voice; that feeling of superiority with which the prosperous man regards the unfortunate one, and that feeling of dislike with which an inferior regards his superior, have no scope in a judgment by one��s equals. But when the crime in question is an offence against a person of a different rank from the accused, then one half of the judges should be the equals of the accused, the other half equals of the plaintiff, that so, every private interest being balanced, by which the appearances of things are involuntarily modified, only the voice of the laws and of truth may be heard. It is also in accordance with justice that an accused person should have power up to a certain point of refusing judges whom he may suspect; and if he is allowed the exercise of this power for some time without opposition, he will seem to condemn himself. Verdicts should be public, and the proofs of guilt public, in order that opinion��which is, perhaps, the only bond of society there is��may place a check on outbursts of force and passion, and that the people may say, ��We are not slaves without defence��: a feeling which both inspires them with courage and is as good as a tribute to a sovereign who understands his real interest. I refrain from pointing out other details and precautions which[138] require similar regulations. I should have said nothing at all, had it been necessary for me to say everything.
