I. 6not like to call themselves slaves, but confine the term to barbarians. Yet, in using this language, they really mean the natural slave of whom we spoke at first; for it must be admitted that some are slaves everywhere, others nowhere. 7The same principle applies to nobility. Hellenes regard themselves as noble everywhere, and not only in their own country, but they deem the barbarians noble only when at home, thereby implying that there are two sorts of nobility and freedom, the one absolute, the other relative. The Helen of Theodectes says:—

'Who would presume to call me servant who am on both sides sprung from the stem of the Gods?'

8What does this mean but that they distinguish freedom and slavery, noble and humble birth, by the two principles of 1255 bgood and evil? They think that as men and animals beget men and animals, so from good men a good man springs. But this is what nature, though she may intend it, often fails to accomplish.

9 We see then that there is some foundation for this difference of opinion, and that some actual slaves and freemen are not so by nature, and also that there is in some cases a marked distinction between the two classes, rendering it expedient and right for the one to be slaves and the others to be masters: the one practising obedience, the others exercising the 10authority which nature intended them to have. The abuse of this authority is injurious to both; for the interests of part and whole^[1], of body and soul, are the same, and the slave is a part of the master, a living but separated part of his bodily frame. Where the relation between them is natural they are friends
