THREE:To examine and distinguish all the different sorts[120] of crimes and the manner of punishing them would now be our natural task, were it not that their nature, which varies with the different circumstances of times and places, would compel us to enter upon too vast and wearisome a mass of detail. But it will suffice to indicate the most general principles and the most pernicious and common errors, in order to undeceive no less those who, from a mistaken love of liberty, would introduce anarchy, than those who would be glad to reduce their fellow-men to the uniform regularity of a convent.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.
