Had I to address nations still destitute of the light of religion, I would say that there is yet another considerable difference between adultery and other crimes. For it springs from the abuse of a constant and universal human impulse, an impulse anterior to, nay, the cause of the institution of society; whereas other crimes, destructive of society, derive their origin rather from momentary passions than from a natural impulse. To anyone cognisant of history and his kind, such an impulse will seem to be equivalent in the same climate to a constant quantity; and if this be so, those laws and customs which seek to diminish the sum-total will be useless or dangerous, because their effect will be to burthen one half of humanity with its own needs and those of others; but those laws, on the contrary, will be the wisest, which following, so to speak, the gentle inclination of the plain, divide the total amount, causing it to ramify into so many equal and small portions, that aridity or overflowing are equally prevented everywhere. Conjugal fidelity is always proportioned to the number and to the freedom of marriages. Where marriages are governed by hereditary prejudices, or[229] bound or loosened by parental power, there the chains are broken by secret intrigue, in despite of ordinary morality, which, whilst conniving at the causes of the offence, makes it its duty to declaim against the results. But there is no need of such reflections for the man who, living in the light of true religion, has higher motives to correct the force of natural effects. Such a crime is of so instantaneous and secret commission, so concealed by the very veil the laws have drawn round it (a veil necessary, indeed, but fragile, and one that enhances, instead of diminishing, the value of the desired object), the occasions for it are so easy, and the consequences so doubtful, that the legislator has it more in his power to prevent than to punish it. As a general rule, in every crime which by its nature must most frequently go unpunished, the penalty attached to it becomes an incentive. It is a quality of our imagination, that difficulties, if they are not insurmountable nor too difficult, relatively to the mental energy of the particular person, excite the imagination more vividly, and place the object desired in larger perspective; for they serve as it were as so many barriers to prevent an erratic and flighty fancy from quitting hold of its object; and, while they compel the imagination to consider the latter in all its bearings, it attaches itself more closely to the pleasant[230] side, to which our mind most naturally inclines, than to the painful side, which it places at a distance.
FORE:This, then, is the way to avoid confounding the relations and invariable nature of things, which, being unlimited by time and in ceaseless operation, confounds and overturns all narrow regulations that depart from it. It is not only the arts of taste and pleasure which have for their universal principle the faithful imitation of nature; but the art of politics itself, at least that which is true and permanent, is subject to this general maxim, since it consists in nothing else than the art of directing in the best way and to the same purposes the immutable sentiments of mankind.
In every criminal case a judge ought to form a complete syllogistic deduction, in which the statement of the general law constitutes the major premiss; the conformity or non-conformity of a particular action with the law, the minor premiss; and acquittal or punishment, the conclusion. When a judge is obliged, or of his own accord wishes, to make even no more than two syllogisms, the door is opened to uncertainty.In the ordinary state of society the death of a citizen is neither useful nor necessary.CHAPTER XIII. PROSECUTIONS AND PRESCRIPTIONS.Even inanimate objects or animals it has been thought through many ages reasonable to punish. In Athens an axe or stone that killed anyone by accident was cast beyond the border; and the English law was only repealed in the present reign which made a cartwheel, a tree, or a beast, that killed a man, forfeit to the State for the benefit of the poor. The Jewish law condemned an ox that gored anyone to death to be stoned, just as it condemned the human murderer. And in the middle ages pigs, horses, or oxen were not only tried judicially like men, with counsel on either side and witnesses, but they were hung on gallows like men, for the better deterrence of their kind in future.[41]I conclude with this reflection, that the scale of punishments should be relative to the condition of a nation. On the hardened minds of a people scarcely emerged from the savage state the impressions made should be stronger and more sensible. One needs a[169] thunderbolt for the destruction of a fierce lion that faces round at the shot of a gun. But in proportion as mens minds become softened in the social state, their sensibility increases, and commensurate with that increase should be the diminution of the force of punishment, if it be desired to maintain any proportion between the object and the sensation that attends it.Such are the fatal arguments employed, if not clearly, at least vaguely, by men disposed to crimes, among whom, as we have seen, the abuse of religion is more potent than religion itself.
