TWO: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 mans 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 citizens 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 ones 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 opinionwhich is, perhaps, the only bond of society there ismay 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. Wise governments suffer not political idleness in the midst of work and industry. I mean by political idleness that existence which contributes nothing to society either by its work or by its wealth; which gains without ever losing; which, stupidly admired and reverenced by the vulgar, is regarded by the wise man with disdain, and with pity for the beings who are its victims; which, being destitute of that stimulus of an active life, the necessity of preserving or increasing[222] the store of worldly goods, leaves to the passions of opinion, not the least strong ones, all their energy. This kind of idleness has been confused by austere declaimers with that of riches, gathered by industry; but it is not for the severe and narrow virtue of some censors, but for the laws, to define what is punishable idleness. He is not guilty of political idleness, who enjoys the fruits of the virtues or vices of his ancestors and sells in exchange for his pleasures bread and existence to the industrious poor, who carry on peacefully the silent war of industry against wealth, instead of by force a war uncertain and sanguinary. The latter kind of idleness is necessary and useful, in proportion as society becomes wider and its government more strict.
