It is true that he was brought up according to the laws and customs of the Persians, and of these laws it must be noted that while they aim, as laws elsewhere, at the common weal, their guiding principle is far other than that which most nations follow.

Most states permit their citizens to bring up their own children at their own discretion, and allow the grown men to regulate their own lives at their own will, and then they lay down certain prohibitions, for example, not to pick and steal, not to break into another man's house, not to strike a man unjustly, not to commit adultery, not to disobey the magistrate, and so forth; and on the transgressor they impose a penalty.

[3] But the Persian laws try, as it were, to steal a march on time, to make their citizens from the beginning incapable of setting their hearts on any wickedness or shameful conduct whatsoever.

And this is how they set about their object.
In their cities they have an open place or square dedicated to Freedom (Free Square they call it), where stand the palace and other public buildings.

From this place all goods for sale are rigidly excluded, and all hawkers and hucksters with their yells and cries and vulgarities.
They must go elsewhere, so that their clamour may not mingle with and mar the grace and orderliness of the educated classes.
