THREE:But whether the international extradition of criminals be useful I would not venture to decide, until laws more in conformity with the needs of humanity, until milder penalties, and until the emancipation of law from the caprice of mere opinion, shall have given[194] security to oppressed innocence and hated virtue; until tyranny shall have been confined, by the force of universal reason which ever more and more unites the interests of kings and subjects, to the vast plains of Asia; however much the conviction of finding nowhere a span of earth where real crimes were pardoned might be the most efficacious way of preventing their occurrence.This, then, is the way to avoid confounding the relations and invariable nature of things, which, being unlimited by time and in ceaseless operation, confounds and overturns all narrow regulations that depart from it. It is not only the arts of taste and pleasure which have for their universal principle the faithful imitation of nature; but the art of politics itself, at least that which is true and permanent, is subject to this general maxim, since it consists in nothing else than the art of directing in the best way and to the same purposes the immutable sentiments of mankind.

THREE:But undoubtedly punishment, although in its origin and present intention vindictive, must exercise a certain preventive force against crime, and this preventive force can scarcely be estimated, for that which is prevented is, of course, not seen. But the efficiency of punishment as a deterrent is proportioned to its certainty, and there is a large element of uncertainty that can never be eliminated. For every malefactor there are two hopes: first, that he may escape detection or apprehension; secondly, that he may escape conviction. That his hopes of impunity are not without reason greater than his fears of punishment the following facts attest.
TWO:No law ought to be promulgated that has not force to back it, or that the nature of things deprives of validity; and as minds are ruled by opinion, which[224] itself follows the slow and indirect impressions of legislation, whilst it resists those that are direct and violent, the most salutary laws become infected with the contempt felt for useless laws, and are regarded rather as obstacles to be surmounted than as the deposit of the public welfare.
