This is the assembly to which he who has visited the institutions of other men, on his return home shall straightway go, and if he have discovered any one who has anything to say about the enactment of laws or education or nurture, or if he have himself made any observations, let him communicate his discoveries to the whole assembly.

And if he be seen to have come home neither better nor worse, let him be praised at any rate for his enthusiasm; and if he be much better, let him be praised so much the more; and not only while he lives but after his death let the assembly honour him with fitting honours.
But if on his return home he appear to have been corrupted, pretending to be wise when he is not, let him hold no communication with any one, whether young or old; and if he will hearken to the rulers, then he shall be permitted to live as a private individual; but if he will not, let him die, if he be convicted in a court of law of interfering about education and the laws.

And if he deserve to be indicted, and none of the magistrates indict him, let that be counted as a disgrace to them when the rewards of virtue are decided.
Let such be the character of the person who goes abroad, and let him go abroad under these conditions.

In the next place, the stranger who comes from abroad should be received in a friendly spirit.

Now there are four kinds of strangers, of whom we must make some mention--the first is he who comes and stays throughout the summer; this class are like birds of passage, taking wing in pursuit of commerce, and flying over the sea to other cities, while the season lasts; he shall be received in market-places and harbours and public buildings, near the city but outside, by those magistrates who are appointed to superintend these matters; and they shall take care that a stranger, whoever he be, duly receives justice; but he shall not be allowed to make any innovation.
They shall hold the intercourse with him which is necessary, and this shall be as little as possible.
