Note (return) — Chapter I

Doctors, again, are more and more recognising that nutrition depends not only upon the chemical composition of food but upon our appetite, and that we can become aware of our appetite and to some extent control and direct it by our will. Sir William Macewen said not long ago, 'We cannot properly digest our food unless we give it a warm welcome from a free mind with the prospect of enjoyment.'[62] But it would not be easy to create by teaching that co-ordination of the intellect and impulse at which Sir William Macewen hints. If you tell a boy that one reason why food is wholesome is because we like it, and that it is therefore our duty to like that food which other facts of our nature have made both wholesome and likeable, you may find yourself stimulating nothing except his sense of humour.
