'Man is what he eats.' With this statement the German materialistic philosopher Feuerbach thought he had put an end to all 'idealistic' speculations about human nature. In fact, however, he was expressing, without knowing it, the most religious idea of man. For long before Feuerbach the same definition of man was given by the Bible. In the biblical story of creation man is presented, first of all, as a hungry being, and the whole world as his food.
