some crimes tend directly to the destruction of society or to the sovereign who represents it; others affect individual citizens, by imperilling their life, their property, or their honour; whilst others, again, are actions contrary to the positive or negative obligations which bind every individual to the public weal.

any action that is not included between the two above-indicated extremes can only be called a crime or punished as such by those who find their interest in so calling it. the uncertainty of these limits has produced in different nations a system of ethics contrary to the system of laws, has produced many actual systems of laws at total variance with one another, and a quantity of laws which expose even the wisest man to the severest penalties. consequently the words virtue and vice have become of vague and variable meaning, and from the uncertainty thus surrounding individual existence, listlessness and a fatal apathy have spread over political communities.

the opinion that each citizen should have liberty to do whatsoever is not contrary to the laws, without fear of any other inconvenience than such as may arise from the action itself—this is the political dogma[203] that should be believed by the people and promulgated by the chief magistrates, a dogma as sacred as that of the incorrupt guardianship of the laws, without which there can be no legitimate society; a just compensation to mankind for their sacrifice of that entire liberty of action which belongs to every sensitive being, and is only limited by the extent of its force. this it is that forms liberal and vigorous souls, and enlightened minds; that makes men virtuous with that virtue which can resist fear, and not with that flexible kind of prudence which is only worthy of a man who can put up with a precarious and uncertain existence.

whosoever will read with a philosophical eye the codes and annals of different nations will find almost always that the names of virtue and vice, of good citizen and criminal, are changed in the course of ages, not in accordance with the changes that occur in the circumstances of a country, and consequently in conformity with the general interest, but in accordance with the passions and errors that have swayed different legislators in succession. he will observe full often, that the passions of one age form the basis of the morality of later ones; that strong passions, the offspring of fanaticism and enthusiasm, weakened and, so to speak, gnawed away by time (which reduces to a level all physical and moral phenomena) become little by little the prudence of the age, and a useful[204] instrument in the hand of the strong man and the clever. in this way the vaguest notions of honour and virtue have been produced; for they change with the changes of time, which causes names to survive things; as also with the changes of rivers and mountains, which form frequently the boundaries of moral no less than of physical geography.
