Chapter XXVIII.—Condemnation of the Greek Legislation.

On this account I reject your legislation also; for there ought to be one common polity for all; but now there are as many different codes as there are states, so that things held disgraceful in some are honourable in others. The Greeks consider intercourse with a mother as unlawful, but this practice is esteemed most becoming by the Persian Magi; pæderasty is condemned by the Barbarians, but by the Romans, who endeavour to collect herds of boys like grazing horses, it is honoured with certain privileges.
