who are without sin alone may cast a stone, if to Caesar you render only the things that are Caesar's, then the foundations of self-respect would be shaken for those who have arranged their lives as if these maxims were not true. A pattern of stereotypes is not neutral. It is not merely a way of substituting order for the great blooming, buzzing confusion of reality. It is not merely a short cut. It is all these things and something more. It is the guarantee of our self-respect; it is the projection upon the world of our own sense of our own value, our own position and our own rights.

They are the fortress of our tradition, and behind its defenses we can continue to feel ourselves safe in the position we occupy.

See his footnote, p. 383.] the Athenian slaves were in great part indistinguishable from free citizens Mr. Zimmern quotes an amusing passage from the Old Oligarch explaining the good treatment of the slaves. "Suppose it were legal for a slave to be beaten by a citizen, it would frequently happen that an Athenian might be mistaken for a slave or an alien and receive a beating;—since the Athenian people is not better clothed than the slave or alien, nor in personal appearance is there any superiority."

With unerring instinct he understood that to justify slavery he must teach the Greeks a way of seeing their slaves that comported with the continuance of slavery.
So, said Aristotle, there are beings who are slaves by nature. [Footnote: Politics , Bk. 1, Ch. 5.] "He then is by nature formed a slave, who is fitted
