TWO: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 vice��the 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 law��that is, of the express or tacit agreements among men��from 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.
THREE: Lastly, among the crimes of the third kind are especially those which disturb the public peace and civic tranquillity; such as noises and riots in the public streets, which were made for the convenience of men and traffic, or fanatical sermons that excite the easily roused passions of the curious multitude. For their passions gather force from the number of hearers, and more from a certain obscure and mysterious enthusiasm, than from clear and quiet reasoning, which never has any influence over a large mass of men.
THREE:[22]Such are some of the problems connected with penology, which best illustrate the imperfection of its hitherto attained results. Only one thing as yet seems to stand out from the mist, which is, that closely associated as crime and punishment are both in thought and speech, they are but little associated in reality. The amount of crime in a country appears to be a given quantity, dependent on quite other causes than the penal laws directed to its repression. The efficiency of the latter seems proportioned[107] to their mildness, not to their severity; such severity being always spoiled by an inevitable moderation in practice. The conclusion, therefore, would seem to be, that a short simple code, with every punishment attached to every offence, with every motive for aggravation of punishment stated, and on so moderate a scale that no discretion for its mitigation should be necessary, would be the means best calculated to give to penal laws their utmost value as preventives of crime, though experience proves that as such preventives their place is a purely secondary one in a really good system of legislation.
THREE:In order that a punishment may attain its object, it is enough if the evil of the punishment exceeds the advantage of the crime, and in this excess of evil the certainty of punishment and the loss of the possible advantage from the crime ought to be considered as part; all beyond this is superfluous and consequently tyrannical. Men regulate their conduct by the reiterated impression of evils they know, not by reason of evils they ignore. Given two nations, in one of which, in the scale of punishments proportioned[167] to the scale of crimes, the severest penalty is perpetual servitude, and in the other the wheel; I say that the former will have as great a dread of its severest punishment as the latter will have; and if there be any reason for transporting to the former country the greater penalties of the other, the same reasoning will serve for increasing still more the penalties of this latter country, passing imperceptibly from the wheel to the slowest and most elaborate tortures, nay, even to the last refinements of that science which tyrants understand only too well.
