THREE: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. 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.

Infectious diseases that affect dogs are important not only from a veterinary standpoint,
but also because of the risk to public health; an example of this is rabies.
