THREE: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.
