the reader of this treatise will perceive that i have omitted all reference to a certain class of crime, which has deluged europe with human blood; a crime which raised those fatal piles, where living human bodies served as food for the flames, and where the blind multitude sought a pleasant spectacle and a sweet harmony from the low dull groans, emitted by wretched sufferers from volumes of black smoke, the smoke of human limbs, whilst their bones and still palpitating entrails were scorched and consumed by the flames. but reasonable men will see that the place, the age, and the subject suffer me not to inquire into the nature of such a crime. it would be too long and remote from my subject to show, how a perfect uniformity of thought ought, contrary to the practice of many countries, to be a necessity in a state; how opinions, which only differ by the most subtle and imperceptible degrees, and are altogether beyond the reach of human intelligence, can[232] yet convulse society, when one of them is not legally authorised in preference to the others; and how the nature of opinions is such, that, whilst some become clearer by virtue of their conflict and opposition, (those that are true floating and surviving, but those that are false sinking to oblivion,) others again, with no inherent self-support, require to be clothed with authority and power. too long would it be to prove, that howsoever hateful may seem the government of force over human minds, with no other triumphs to boast of but dissimulation and debasement, and howsoever contrary it may seem to the spirit of gentleness and fraternity, commanded alike by reason and the authority we most venerate, it is yet necessary and indispensable. all this should be taken as clearly proved and conformable to the true interests of humanity, if there be anyone who, with recognised authority, acts accordingly. i speak only of crimes that spring from the nature of humanity and the social compact; not of sins, of which even the temporal punishments should be regulated by other principles than those of a narrow philosophy.
