ONE: If the interpretation of laws is an evil, it is clear that their obscurity, which necessarily involves interpretation, must be an evil also, and an evil which will be at its worst where the laws are written in any other than the vernacular language of a country. For in that case the people, being unable to judge of themselves how it may fare with their liberty or their limbs, are made dependent on a small class of men; and a book, which should be sacred and open to all, becomes, by virtue of its language, a private and, so to speak, a family manual.Lastly, some have thought that the gravity of an acts sinfulness should be an element in the measure of crimes. But an impartial observer of the true relations between man and man, and between man[201] and God, will easily perceive the fallacy of this opinion. For the former relationship is one of equality; necessity alone, from the clash of passions and opposing interests, having given rise to the idea of the public utility, the basis of human justice. But the other relationship is one of dependence on a perfect Being and Creator, who has reserved to Himself alone the right of being at the same time legislator and judge, and can alone unite the two functions without bad effects. If He has decreed eternal punishments to those who disobey His omnipotence, what insect shall dare to take the place of Divine justice, or shall wish to avenge that Being, who is all-sufficient to Himself, who can receive from things no impression of pleasure nor of pain, and who alone of all beings acts without reaction? The degree of sinfulness in an action depends on the unsearchable wickedness of the heart, which cannot be known by finite beings without a revelation. How, then, found thereon a standard for the punishment of crimes? In such a case men might punish when God pardons, and pardon when God punishes. If men can act contrary to the Almighty by offending Him, they may also do so in the punishments they inflict.
THREE:[19]Another way to prevent crimes is to reward virtue. On this head I notice a general silence in the laws of all nations to this day. If prizes offered by academies to the discoverers of useful truths have caused the multiplication of knowledge and of good books, why should not virtuous actions also be multiplied, by prizes distributed from the munificence of the sovereign? The money of honour ever remains unexhausted and fruitful in the hands of the legislator who wisely distributes it.
THREE:There are three sources of the moral and political principles which govern mankind, namely, revelation, natural law, and social conventions. With regard to their principal object there is no comparison between the first and the other two, but they all resemble one another in this, that they all three conduce to the happiness of this present mortal life. To consider the different relations of social conventions is not to exclude those of revelation and natural law; rather it is the thousandfold changes which revelation and natural law, divine and immutable though they be, have undergone in the depraved mind of man, by his own fault, owing to false religions and arbitrary notions of virtue and vice, that make it appear necessary to examine, apart from all other considerations, the result of purely human conventions, expressed or implied, for the public need and welfare: this being an idea in which every sect and every moral system must necessarily agree; and it will always be a laudable endeavour, which seeks to constrain the headstrong and unbelieving to conform to the principles that induce men to live together in society. There are, then, three distinct kinds of virtue and vicethe religious, the natural, and the political. These three kinds ought never to conflict, although all the consequences and duties that flow from any one of them do not necessarily flow from the others. The natural law does not require all that revelation requires,[114] nor does the purely social law require all that natural law requires; but it is most important to distinguish the consequences of the conventional lawthat is, of the express or tacit agreements among menfrom the consequences of the natural law or of revelation, because therein lies the limit of that power, which can rightly be exercised between man and man without a special mandate from the Supreme Being. Consequently the idea of political virtue may, without any slur upon it, be said to be variable; that of natural virtue would be always clear and manifest, were it not obscured by the stupidity or the passions of men; whilst the idea of religious virtue remains ever one and the same, because revealed directly from God and by Him preserved.There are, however, certain limitations even to the supposed universality of the custom. For the Roman jurists did not consider a re-conviction as a circumstance in itself which justified aggravation of punishment; and all that can be gathered from some fragments in the Pandects and Code is, that some particular cases of repeated crimes were punished more severely than a first offence. But they were crimes of the same kind; and a man whose first crime[91] was a theft and whose second was an assault would not have incurred an aggravated penalty. It is the same to-day in the Austrian, Tuscan, and a few other codes: a second crime is only punished more severely as a second crime when it is of the same kind as the first, so that it would not suffice to prove simply a previous conviction for felony irrespective of the particular sort. There is also another limitation that has sometimes been recognised, for in the Roman law the rule of an increased penalty fell to the ground, if three years elapsed without offence between the punishment for one crime and the commission of a second.[49]
