Given the necessity of the aggregation of mankind, and given the covenants which necessarily result from the very opposition of private interests, a scale of offences may be traced, beginning with those which tend directly to the destruction of society, and ending with acts of the smallest possible injustice committed against individual members of it. Between these extremes are comprised all the actions opposed to the public welfare which are called crimes, and which by imperceptible degrees decrease in enormity from the highest to the lowest. If the infinite and obscure combinations of human actions admitted of mathematical treatment, there ought to be a corresponding scale of punishments, varying from the severest to the slightest penalty. If there were an exact and universal scale of crimes and punishments, we should have an approximate and general test by[199] which to gauge the degrees of tyranny and liberty in different governments, the relative state of the humanity or wickedness of different nations. But the wise legislator will rest satisfied with marking out the principal divisions in such a scale, so as not to invert their order, nor to affix to crimes of the first degree punishments due to those of the last.
It is not easy in the days of a milder administration of penal laws than a century ago the most sanguine could have dreamed of to do full justice to those who laboured, as Beccaria and his friends did, at the peril of their lives and liberties, for those very immunities which we now enjoy. We cannot conceive that it should ever have been necessary to argue against torture, or that it should have been a bold thing to do so; still less can we conceive that it should ever have had its defenders, or that men should have been contented with the sophism, that it was indeed an evil, but an evil which was necessary and inevitable.I conclude with this reflection, that the scale of punishments should be relative to the condition of a nation. On the hardened minds of a people scarcely emerged from the savage state the impressions made should be stronger and more sensible. One needs a[169] thunderbolt for the destruction of a fierce lion that faces round at the shot of a gun. But in proportion as mens minds become softened in the social state, their sensibility increases, and commensurate with that increase should be the diminution of the force of punishment, if it be desired to maintain any proportion between the object and the sensation that attends it. Some remnants of the laws of an ancient conquering people, which a prince who reigned in Constantinople some 1,200 years ago caused to be compiled, mixed up afterwards with Lombard rites and packed in the miscellaneous volumes of private and obscure commentatorsthese are what form that set of traditional opinions which from a great part of Europe receive nevertheless the name of laws; and to this day it is a fact, as disastrous as it is common, that some opinion of Carpzovius, some old custom pointed out by Clarus, or some form of torture suggested in terms of complacent ferocity by Farinaccius, constitute the laws, so carelessly followed by those, who in all trembling ought to exercise their government over the lives and fortunes of men. These laws, the dregs of the most barbarous ages, are examined in this book in so far as regards criminal jurisprudence, and I have dared to expose their faults to the directors of the public happiness in a style which may keep at[112] a distance the unenlightened and intolerant multitude. The spirit of frank inquiry after truth, of freedom from commonplace opinions, in which this book is written, is a result of the mild and enlightened Government under which the Author lives. The great monarchs, the benefactors of humanity, who are now our rulers, love the truths expounded, with force but without fanaticism, by the obscure philosopher, who is only roused to indignation by the excesses of tyranny, but is restrained by reason; and existing abuses, for whosoever well studies all the circumstances, are the satire and reproach of past ages, and by no means of the present age or of its lawgivers. The first consequence of these principles is, that the laws alone can decree punishments for crimes, and this authority can only rest with the legislator, who represents collective society as united by a social contract. No magistrate (who is part of society) can justly inflict punishments upon another member of the same society. But since a punishment that exceeds the legally fixed limit is the lawful punishment plus another one, a magistrate can, under no pretext of zeal or the public good, add to the penalty already decreed against a delinquent citizen.Lastly, the surest but most difficult means of preventing crimes is to improve educationa subject too vast for present discussion, and lying beyond the limits of my treatise; a subject, I will also say, too intimately connected with the nature of government for it ever to be aught but a barren field, only cultivated here and there by a few philosophers, down to the remotest ages of public prosperity. A great man, who enlightens the humanity that persecutes him, has shown in detail the chief educational maxims of real utility to mankind; namely, that it consists less in a barren multiplicity of subjects than in their choice selection; in substituting originals for copies in the moral as in the physical phenomena presented by chance or intention to the fresh minds of youth; in inclining them to virtue by the easy path of feeling;[251] and in deterring them from evil by the sure path of necessity and disadvantage, not by the uncertain method of command, which never obtains more than a simulated and transitory obedience.
