He generally ate as long as he found pleasure in eating, and when he sat down to table he desired no other sauce but a sound appetite.

All sorts of drink were alike pleasing to him, because he never drank but when he was thirsty; and if sometimes he was invited to a feast, he easily avoided eating and drinking to excess, which many find very difficult to do in those occasions.

But he advised those who had no government of themselves never to taste of things that tempt a man to eat when he is no longer hungry, and that excite him to drink when his thirst is already quenched, because it is this that spoils the stomach, causes the headache, and puts the soul into disorder.

And he said, between jest and earnest, that he believed it was with such meats as those that Circe changed men into swine, and that Ulysses avoided that transformation by the counsel of Mercury, and because he had temperance enough to abstain from tasting them.
As to love, his advice was to avoid carefully the company of beautiful persons, saying it was very difficult to be near them and escape being taken in the snare; and, having been told that Critobulus had given a kiss to the son of Alcibiades, who was a very handsome youth, he held this discourse to Xenophon, in the presence of Critobulus himself.
"Tell me, Xenophon, what opinion have you hitherto had of Critobulus?
Have you placed him in the rank of the temperate and judicious; or with the debauched and imprudent ?" "I have always looked upon him," answered Xenophon, "to be a very virtuous and prudent man." "Change your opinion," replied Socrates, "and believe him more rash than if he threw himself on the points of naked swords or leapt into the fire." "And what have you seen him do," said Xenophon, "that gives you reason to speak thus of him ?" "Why, he had the rashness," answered Socrates, "to kiss the son of Alcibiades, who is so beautiful and charming." "And is this all ?" said Xenophon; "for my part, I think I could also willingly expose myself to the same danger that he did." "Wretch, that you are!" replied Socrates.

"Do you consider what happens to you after you have kissed a beautiful face?
Do you not lose your liberty?
Do you not become a slave?
Do you not engage yourself in a vast expense to procure a sinful pleasure?
Do you not find yourself in an incapacity of doing what is good, and that you subject yourself to the necessity of employing your whole time and person in the pursuit of what you would despise, if your reason were not corrupted ?" "Good God!" cried Xenophon, "this is ascribing a wonderful power to a kiss forsooth." "And are you surprised at it ?" answered Socrates.
