Note (return) — Chapter I

In other matters than politics the influence of the fruit of that tree is now spreading further over our lives. Whether we will or not, the old unthinking obedience to appetite in eating is more and more affected by our knowledge, imperfect though that be, of the physiological results of the quantity and kind of our food. Mr. Chesterton cries out, like the Cyclops in the play, against those who complicate the life of man, and tells us to eat 'caviare on impulse,' instead of 'grape nuts on principle.'[59] But since we cannot unlearn our knowledge, Mr. Chesterton is only telling us to eat caviare on principle. The physician, when he knows the part which mental suggestion plays in the cure of disease, may hate and fear his knowledge, but he cannot divest himself of it. He finds himself watching the unintended effects of his words and tones and gestures, until he realises that in spite of himself he is calculating the means by which such effects can be produced. After a time, even his patients may learn to watch the effect of 'a good bedside manner' on themselves.
