One must not forget that recovery is brought about not by the physician, but by the sick man himself. He heals himself, by his own power, exactly as he walks by means of his own power, or eats, or thinks, breathes or sleeps. – Georg Groddeck, The Book of the It, 1923

‘Tis not always in a physician’s power to cure the sick; at times the disease is stronger than trained art. – Ovid
