Socrates, a wise man, tried to abstain from all unnecessary things. He said that food should serve you in fighting your hunger, and not in developing sophisticated tastes, and he asked his students to follow his rule. He reminded his students about the wise Odysseus, whom Circe, an evil sorceress, could not subject to her magic, because he did not eat to excess. But the members of his crew, his friends, were turned into a herd of pigs by her as soon as they rushed to the abundance of sweet food.
