And the rest of the Pythagoreans used to say, according to the account given by Aristoxenus, in the tenth book of his Laws on Education, that his precepts ought not to be divulged to all the world; and Xenophilus, the Pythagorean, when he was asked what was the best way for a man to educate his son, said, “That he must first of all take care that he was born in a city which enjoyed good laws.” Pythagoras, too, formed many excellent men in Italy, by his precepts, and among them Zaleucus,[110] and Charondas,[111] the lawgivers. XVI. For he was very eminent for his power of attracting friendships; and among other things, if ever he heard that any one had any community of symbols with him, he at once made him a companion and a friend. XVII. Now, what he called his symbols were such as these. “Do not stir the fire with a sword.” “Do not sit down on a bushel.” “Do not devour your heart.” “Do not aid men in discarding a burden, but in increasing one.” “Always have your bed packed up.” “Do not bear the image of a God on a ring.” “Efface the traces of a pot in the ashes.” “Do not wipe a seat with a lamp.” “Do not make water in the sunshine.” “Do not walk in the main street.” “Do not offer your right hand lightly.” “Do not cherish swallows under your roof.” “Do not cherish birds with crooked talons.” “Do not defile; and do not stand upon the parings of your nails, or the cuttings of your hair.” “Avoid a sharp sword.” “When you are travelling abroad, look not back at your own borders.” Now the precept not to stir fire with a sword meant, not to provoke the anger or swelling pride of powerful men; not to violate the beam of the balance meant, not to transgress fairness and justice; not to sit on a bushel is to have an equal care for the present and for the future, for by the bushel is meant one’s daily food. By not devouring one’s heart, he intended to show that we ought not to waste away our souls with grief and sorrow. In the precept that a man when travelling abroad should not turn his eyes back, he recommended those who were departing from life not to be desirous to live, and not to be too much attracted by the pleasures here on earth. And the other symbols may be explained in a similar manner, that we may not be too prolix here.
