Corporal and painful punishments should not be inflicted for those crimes which have their foundation in pride, and draw from pain itself their glory and nutriment. For such crimes ridicule and infamy are more fitted, these being penalties which curb the[184] pride of fanatics by the pride of the beholders, and only let truth itself escape their tenacity by slow and obstinate efforts. By such an opposition of forces against forces, and of opinions against opinions, the wise legislator destroys that admiration and astonishment among a people, which a false principle causes, whose original absurdity is usually hidden from view by the plausible conclusions deduced from it.
Penalties of infamy ought neither to be too common, nor to fall upon too many persons at a time; not too common, because the real and too frequent effects of matters of opinion weaken the force of opinion itself; not too general, because the disgrace of many persons resolves itself into the disgrace of none of them.
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.
