For it is only in the world of words that food can function as a metaphor for sex at all, or sex as a metaphor for food. Yet the fact that language issues from the same orifice in which nutrition is imbibed means that words and food are locked in an eternal rivalry. "The mouth speaks with its tongue and tastes flavors," wrote Saint Catherine, who gave up food in order to incorporate the word of God. Since language must compete with food to gain the sole possession of the mouth, we must either speak and go hungry, or shut up and eat.
