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. In the ordinary state of society the death of a citizen is neither useful nor necessary.

But why does this crime never entail disgrace upon its author, seeing that it is a theft against the prince, and consequently against the nation? I answer, that offences which men do not consider can be committed against themselves do not interest them enough to produce public indignation against their perpetrator. Smuggling is an offence of this character. Men in general, on whom remote consequences make very feeble impressions, do not perceive the harm that smuggling can do them, nay, often they enjoy a present advantage from it. They only perceive the injury done to the sovereign; they are not interested, therefore, in withdrawing their favour from a smuggler as much as they are in doing so from a man who commits a theft in private life, who forges a signature, or brings upon them other evils. The principle is self-evident, that every sensitive being only interests himself in the evils which he knows. This crime arises from the law itself; since the benefit it promises increases with the increase of the import duty, and therefore the temptation and the facility of committing it increases with the circumference of territory to be guarded and the small size of the prohibited wares. The penalty of losing both the prohibited goods, and whatever effects are found with them, is most just; but its efficacy will be greater in proportion as the import duty is lower, because men only incur risks relative to the advantage derivable from the prosperous issue of their undertaking.

By the same rule, in the case of theft, the value of the thing stolen, with some equivalent for the trouble of its recovery, taken from the offender or made a lien on his earnings, appears to be all that justice can demand. Sir Samuel Romilly, himself second to none as a lawyer, wrote seventy years ago: If the restitution of the property stolen, and only a few weeks or even but a few days imprisonment were the unavoidable consequence of theft, no theft would ever be committed. Yet the following sentences are taken[85] at random from authentic English sources: three months imprisonment for stealing a pipe, six months for stealing a penny, a twelvemonth for stealing an umbrella, five years penal servitude for stealing some stamps from a letter, seven years for stealing twopence. In such cases the principle of vindictiveness exceeds the limits of necessity, and therefore of justice; whilst the law loses all its dignity as the expression of unimpassioned resentment. So great, however, did the changes appear to be, that Sir James Mackintosh declared, towards the close of his life, that it was as if he had lived in two different countries, such was the contrast between the past and the present. Yet Sir James died in the very year that the first Reform Bill passed, and it was not till after that event that any really great progress was made towards ameliorating the penal laws.

In France Beccarias book became widely popular, and many writers helped to propagate his ideas, such as Servan, Brissot, Lacretelle, and Pastoret. Lacretelle attributes the whole impulse of criminal law reform to Beccaria, while regretting that Montesquieu had not said enough to attract general attention to the subject. His book is said to have so changed the spirit of the old French criminal tribunals, that, ten years before the Revolution, they bore no resemblance to their former selves. All the younger magistrates gave their judgments more according to the principles of Beccaria than according to the text of the law.[21][35] The result of the agitation appeared in the Royal Ordinances of 1780 and 1788, directed to the diminution of torture, the only reforms which preceded the Revolution. It is said that the last time anyone was tortured in France was in the year 1788, the last year of the ancien rgime. At the very beginning of the Revolution more than a hundred different offences ceased to incur the penalty of death.

Nor was it only in Europe that Beccarias influence thus prevailed, for as soon as the American Colonies had shaken off their English connection they began to reform their penal laws. When the Revolution began there were in Pennsylvania nearly twenty crimes punishable by death, and within eighteen years of its close the penal code was thoroughly transformed, it being ordained in 1794 that no crime should any longer be capital but murder in the first degree. It is true that this was but a return to the principles adopted by Penn on the settlement of the colony, but Penns penal code was annulled by Queen Anne, and the English Government insisted on a strict adherence to the charter from Charles II., which enjoined the retention of the Statute and the Common Law of England. When, therefore, the new Constitution was formed in 1776, the arguments of Beccaria gave fresh life to the memories of Penn.[25]

Even when Paris was reached, and Beccaria and Alessandro were warmly welcomed by DAlembert, Morellet, Diderot, and Baron Holbach, the homesickness remained. You would not believe, says Beccaria to his wife, the welcomes, the politeness, the demonstrations of friendship and esteem, which they have shown to me and my companion. Diderot, Baron Holbach, and DAlembert especially enchant us. The latter is a superior man, and most simple at the same time. Diderot displays enthusiasm and good humour in all he does. In short, nothing is wanting to me but yourself. All do their best to please me, and those who do so are the greatest men in Europe. All of them deign to listen to me, and no one shows the slightest air of superiority. Yet[24] Morellet tells us that even on arrival Beccaria was so absorbed in melancholy, that it was difficult to get four consecutive words from his mouth.

The good faith of contracts and the security of commerce compel the legislator to assure to creditors the persons of insolvent debtors. But I think it important to distinguish the fraudulent from the innocent bankrupt, the former of whom should receive the same punishment as that assigned to false coiners, since it is no greater crime to falsify a piece of coined money, the pledge of mens mutual[217] obligations, than to falsify those obligations themselves. But the innocent bankrupthe who, after a searching inquiry, has proved before his judges that the wickedness or misfortune of some one else, or the inevitable vicissitudes of human prudence, have despoiled him of his substancefor what barbarous reason ought such an one to be thrown into prison, and deprived of the only poor benefit that remains to him, a barren liberty, in order to suffer the agonies of the really guilty, and, in despair at his ruined honesty, to repent perhaps of that innocence, by which he lived peacefully under the protection of those laws that it was not in his power not to offend against? Laws, too, dictated by the powerful by reason of their rapacity, and endured by the feeble by reason of that hope, which generally glimmers in the human heart, and leads us to believe that unfavourable contingencies are reserved for others, favourable ones for ourselves! Men left to their natural feelings love cruel laws, however much, as subject to them themselves, it might be for their individual interest that they should be mitigated; because their fear of being injured by others is greater than their desire to inflict injuries themselves.

It is a great point in every good system of laws to determine exactly the credibility of witnesses and the proofs of guilt Every reasonable manthat is, every man with a certain connection between his ideas and with feelings like those of other menis capable of bearing witness. The true measure of his credibility is only the interest he has in speaking or in not speaking the truth; so that nothing can be more frivolous than to reject the evidence of women on the pretext of their feebleness, nothing more childish than to apply the results of real death to civil death as regards the testimony of the condemned, nothing more unmeaning than to insist on the mark of infamy in the infamous when they have no interest in lying.

Adultery is a crime which, politically considered, derives its force and direction from two causes, namely, from the variable laws in force among mankind, and from that strongest of all attractions which draws one sex towards the other.[70]

It would be possible to distinguish a case of fraud from a grave fault, a grave fault from a light one, and this again from perfect innocence; then to affix to the first the penalties due for crimes of falsification; to the second lesser penalties, but with the loss of personal liberty; and, reserving for the last degree the free choice of the means of recovery, to deprive the third degree of such liberty, whilst leaving it to a mans creditors. But the distinction between grave and light should be fixed by the blind impartiality of the laws, not by the dangerous and arbitrary wisdom of a judge. The fixings of limits are as necessary in politics as in mathematics, equally in the measurement[219] of the public welfare as in the measurement of magnitudes.[68]
