ONE: We have seen that the true measure of crimes is the injury done to society. This is one of those palpable truths which, however little dependent on quadrants or telescopes for their discovery, and fully within the reach of any ordinary intelligence, are yet, by a marvellous combination of circumstances, only recognised clearly and firmly by some few thinkers, belonging to every nationality and to every age. But Asiatic ideas, and passions clothed with authority and power, have, generally by imperceptible movements, sometimes by violent assaults on the timid credulity of mankind, dissipated those simple notions, which perhaps formed the first philosophy of primitive communities, and to which the enlightenment of this age seems likely to reconduct us, but to do so with that greater sureness, which can be gained from an exact[200] investigation into things, from a thousand unhappy experiences, and from the very obstacles that militate against it.Analogy between crime and punishment is another idea which, except in the case of death for death, has been relegated from the practice of most criminal laws. Yet the principle has in its favour the authority of Moses, the authority of the whole world and of all time, that punishment should, if possible, resemble the crime it punishes in kind; so that a man who blinds another should be blinded himself, he who disfigures another be disfigured himself. Thus in the old-world mythology, Theseus and Hercules inflict on the evil powers they conquer the same cruelties their victims were famous for; Termenus having his skull broken because with his own skull he broke the heads of others; and Busiris, who sacrificed others, being himself sacrificed in his turn. Both Montesquieu and Beccaria also advocate analogy in punishment, and so does Bentham to some degree; there being, indeed, few greater contrasts between the theories of the great English jurist and modern English practice than that the former should not have deprecated some suffering by burning as a penalty analogous to the crime of arson, and that he should have advised the transfixing of a forgers hand or of a calumniators tongue[79] by an iron instrument before the public gaze as good and efficient punishments for forgery and slander.
TWO: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.
