THREE:Banishment, it would seem, should be employed[181] in the case of those against whom, when accused of an atrocious crime, there is a great probability but not a certainty of guilt; but for this purpose a statute is required, as little arbitrary and as precise as possible, condemning to banishment any man who shall have placed his country in the fatal dilemma of either fearing him or of injuring him, leaving him, however, the sacred right of proving his innocence. Stronger reasons then should exist to justify the banishment of a native than of a foreigner, of a man criminated for the first time than of one who has been often so situated.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.
