Hope, the best comfort of our imperfect condition, was not denied to the Roman slave; and if he had any opportunity of rendering himself either useful or agreeable, he might very naturally expect that the diligence and fidelity of a few years would be rewarded with the inestimable gift of freedom. The benevolence of the master was so frequently prompted by the meaner suggestions of vanity and avarice, that the laws found it more necessary to restrain than to encourage a profuse and undistinguishing liberality, which might degenerate into a very dangerous abuse. It was a maxim of ancient jurisprudence, that a slave had not any country of his own; he acquired with his liberty an admission into the political society of which his patron was a member. The consequences of this maxim would have prostituted the privileges of the Roman city to a mean and promiscuous multitude. Some seasonable exceptions were therefore provided; and the honorable distinction was confined to such slaves only as, for just causes, and with the approbation of the magistrate, should receive a solemn and legal manumission. Even these chosen freedmen obtained no more than the private rights of citizens, and were rigorously excluded from civil or military honors. Whatever might be the merit or fortune of their sons, _they_ likewise were esteemed unworthy of a seat in the senate; nor were the traces of a servile origin allowed to be completely obliterated till the third or fourth generation. Without destroying the distinction of ranks, a distant prospect of freedom and honors was presented, even to those whom pride and prejudice almost disdained to number among the human species.
