that the virtue of the one cannot in general be the same as the virtue of the other, although it may be true of some particular citizen; for the virtue of the magistrate must be different from the virtue of the citizen. For which reason Jason declared that was he deprived of his kingdom he should pine away with regret, as not knowing how to live a private man. But it is a great recommendation to know how to command as well as to obey; and to do both these things well is the virtue of an accomplished citizen. If then the virtue of a good man consists only in being able to command, but the virtue of a good citizen renders him equally fit for the one as well as the other, the commendation of both of them is not the same. It appears, then, that both he who commands and he who obeys should each of them learn their separate business: but that the citizen should be master of and take part in both these, as any one may easily perceive; in a family government there is no occasion for the master to know how to perform the necessary offices, but rather to enjoy the labour of others; for to do the other is a servile part. I mean by the other, the common family business of the slave.
There are many sorts of slaves; for their employments are various: of these the handicraftsmen are one, who, as their name imports, get their living by the labour of their hands, and amongst these all mechanics are included; [1277b] for which reasons such workmen, in some states, were not formerly admitted into any share in the government; till at length democracies were established: it is not therefore proper for any man of honour, or any citizen, or any one who engages in public affairs, to learn these servile employments without they have occasion for them for their own use; for without this was observed the distinction between a master and a slave would be lost.
