A complex social system devises for itself ways of behaving that suggest that human intercourse is disembodied compared with. that of animal creation. It uses different degrees of disembodiment to express the social hierarchy. The more refinement, the less smacking of the lips when eating, the less mastication, the less the sound of breathing and walking, the more carefully modulated the laughter, the more controlled the signs of anger, the clearer comes the priestly-aristocratic image. Since food takes a different place in different cultures this general rule is more difficult to see at work in table manners than in habits of dress and grooming.
