Besides this, he who affirms that a slave does not sometimes confer a benefit upon his master is ignorant of the rights of man; for the question is, not what the station in life of the giver may be, but what his intentions are. The path of virtue is closed to no one, it lies open to all; it admits and invites all, whether they be freeborn men, slaves or freedmen, kings or exiles; it requires no qualifications of family or of property, it is satisfied with a mere man. What, indeed, should we have to trust to for defence against sudden misfortunes, what could a noble mind promise to itself to keep unshaken, if virtue could be lost together with prosperity? If a slave cannot confer a benefit upon his master, then no subject can confer a benefit upon his king, and no soldier upon his general; for so long as the man is subject to supreme authority, the form of authority can make no difference. If main force, or the fear of death and torture, can prevent a slave from gaining any title to his master’s gratitude, they will also prevent the subjects of a king, or the soldiers of a general from doing so, for the same things may happen to either of these classes of men, though under different names.
