Slavery, properly so called, is the establishment of a right which gives to one man such a power over another as renders him absolute master of his life and fortune. The state of slavery is in its own nature bad. It is neither useful to the master nor to the slave; not to the slave, because he can do nothing through a motive of virtue; nor to the master, because by having an unlimited authority over his slaves he insensibly accustoms himself to the want of all moral virtues, and thence becomes fierce, hasty, severe, choleric, voluptuous, and cruel. ... where it is of the utmost importance that human nature should not be debased or dispirited, there ought to be no slavery. In democracies, where they are all upon equality; and in aristocracies, where the laws ought to use their utmost endeavors to procure as great an equality as the nature of the government will permit, slavery is contrary to the spirit of the constitution: it only contributes to give a power and luxury to the citizens which they ought not to have.
