XXXIV. Though punishment does not exceed the bounds of justice, yet in certain cases it may be mitigated in favour of a criminal, from motives of mercy, except where such lenity to the guilty is deemed cruelty to the innocent, whose safety is thereby endangered. For the escape of a criminal is often an encouragement to his own perseverance in iniquity, and to that of others, who are encouraged by the example. Necessity indeed requires the sharpest remedies for the suppression of crimes; especially, where the incentives of habit and a facility to commit them prevail.
XXXV. The divine law given to the Hebrews punished the stealing of cattle from a pasture with more severity than breaking into a house, on account of the ease with which the former of those crimes might be committed. Exod. xxii. 1–9. Justin in speaking of the Scythians, describes them as "punishing theft with more severity than any other crime; for as they have no covered habitations to protect their flocks, and herds from depredations, what could be safe, if thieving were allowed?" Though the FAMILIARITY of certain crimes may prevent us from being surprised at their perpetration, it by no means diminishes their atrocity, or demands a mitigation of punishment. But, as Saturninus says, "the giant-strides of crimes must be impeded with the strongest bands." In trials for offences, clemency may be indulged, but in the passing of laws severity should be regarded: For the GENERAL nature of law requires that offences should be pursued with rigour: but in trials, in which individuals are the objects concerned, there may be circumstances to aggravate or diminish the offence: which leaves room for the discretionary exercise of rigour or lenity.
XXXVI. and XXXVII. The inclination to mitigate penalties, where the urgent motives to enforce them no longer exist, is a point of compassion perfectly distinct from the abolition of punishment altogether.
Nor has any thing been omitted, that might tend to clear up this difficult and delicate question. But every point, we trust, has been examined in its proper place, either respecting the magnitude of crimes, as measured by the injury done, the habitual commission of such offences, or the influence of the motives, sufficient to encourage or restrain them. Indeed the character of the offender affords the most conclusive means for judging of his capacity to commit the crime; and that of the sufferer often contributes something towards enabling us to estimate the due proportion of the penalty. The circumstances of the time, when—the place, where—or the facility, with which a crime is perpetrated, tend to aggravate, or lessen its enormity. The length of time intervening between a criminal design and its execution gives us some opportunity to examine how far the perpetrator was actuated by a malicious purpose. But the true complexion of a crime is to be discovered, partly from the nature of those appetites, to which it owes its birth; and partly, on the other hand, from the nature of the motives which ought to have restrained them. By this class of appetites the magnitude of a crime may be judged of; and the consequences are the motives which should operate to restrain them.
XXXVIII. It has been shewn before, and it is a truth founded upon historical fact, that wars are undertaken, as acts of punishment, and this motive, added to that of redress for injuries, is the source, from which the duties of nations, relating to war, take their rise. But it is not every injury, that can be construed into a just ground of war. For laws, whose vengeance is meant to protect the innocent, and to fall upon the guilty, do not regard every case, as a sufficient warrant for their exertion. So that there is much truth in the opinion of Sopater, who says that there are trivial and common offences, which it is better to pass over unnoticed, than to punish.
XXXIX. The maxim laid down by Cato, in his speech in defence of the Rhodians, that it is not right any one should be punished upon the bare suspicion of his having intended to commit aggression or injury, was well applied in that place; because no positive decree of the people of Rhodes could be alleged against them, nor was there any other proof beyond the CONJECTURE of their wavering in their policy. But this maxim is not universally true.
For where intention has proceeded to any outward and visible signs of insatiable ambition and injustice, it is deemed a proper object of jealousy, and even of punishment. Upon this principle, the Romans, as may be seen from Livy's account in the xlii. book and xxx. chapter of his history, thought themselves justified in declaring war against Perseus, King of Macedon, unless he gave satisfactory proof, that he had no hostile intentions against them, in the naval and military armaments, which he was preparing. And we are informed by the same historians, that the Rhodians urged it as a rule established by the laws and customs of all civilized states; that if any one wished the destruction of an enemy, he could not punish him with death, unless he had actually done something to deserve it.
But it is not every unjust design, though indicated by some outward act, which can authorize and direct hostilities. For if the actual commission of crimes and aggressions is, in some cases, proper to be overlooked, much more will it be a mark of deliberate caution to use the same forbearance, where nothing further than the pure design of aggression appears. A forbearance which Cicero justifies upon the possibility that the enemy may have repented of his design, before the execution of it. No conclusive inference can be drawn from the severity of Mosaic Law against all intended acts of impiety and murder. For, in comparing human laws with the divine counsels, whose depths we cannot sound, we are liable to run into error; and the impulse of anger, where it is attended with no fatal consequence, is a case in which the infirmity of human nature calls for pardon. For altho' the precepts of the decalogue are designed to lay a restraint upon unlawful desires as well as upon unlawful actions, yet in addition to the spiritual sense, that which is called the carnal, or external commandment applies to those dispositions that are manifested by some open act. This interpretation may be deduced from a passage in the gospel of St. Mark, c. x. 19, where the prohibition to defraud is immediately preceded by the injunction not to steal. So that intended aggressions are not to be punished by force of arms, except in cases of atrocity, where the very design threatens consequences of the greatest danger. All punishment therefore must have in view either security against future aggressions, reparation for the injury done to national or private honour, or it must be used as an example of awful severity.
XL. It is proper also to observe that kings and those who are possessed of sovereign power have a right to exact punishment not only for injuries affecting immediately themselves or their own subjects, but for gross violations of the law of nature and of nations, done to other states and subjects. For the liberty of inflicting punishment for the peace and welfare of society, which belonged to individuals in the early ages of the world, was converted into the judicial authority of sovereign states and princes; a right devolving upon them not only as rulers of others, but as subject to the controul of no earthly power. For that is a right, which can belong to no subject. It is never safe to leave the entire assertion of a man's own rights, or the punishment of his wrongs, to his own judgment; for he cannot be entirely disinterested in his own cause. Partiality will make him fall short of, or prejudice will make him exceed the bounds of justice. It was the theme of praise bestowed upon the heroes of antiquity, that in their most arduous undertakings they avenged the wrongs of others rather than their own. Upon this principle there can be no hesitation in pronouncing all wars to be just, that are made upon pirates, general robbers, and enemies of the human race. So far this opinion agrees with that of Innocentius and others, who maintain all war to be lawful against those who have renounced the ties and law of nature. An opinion directly the reverse is held by Victoria, Vasquez, Azorius, Molina, and others, who deem an aggression done to a prince, his government, or his subjects, or civil jurisdiction over the aggressor, the only justifiable warrant for inflicting punishment, particularly the punishment of hostilities. For they suppose punishment to be an effect purely arising from the authority of civil law, whereas, according to the proofs established in the beginning of this treatise, it was shewn to be a right resulting entirely from the law of nature.
If the opinion of those, from whom we differ, be admitted, no enemy will have a right to punish another, by the prosecution of a just war; a right, which notwithstanding is allowed and confirmed by the practice of all nations, not only after the defeat of an enemy, but during the continuance of a war; and that too, not from any civil jurisdiction, but from a natural right, which prevailed long before the foundation of states, and which still exists in all its force, in places, where the community consists of families distinct, and united as the subjects of one sovereign.
