William Osler Quote

Faith is indeed one of the miracles of human nature which science is as ready to accept as it is to study its marvellous effects. When we realise what a vast asset it has been in history, the part which it has played in the healing art seems insignificant, and yet there is no department of knowledge more favourable to an impartial study of its effects, and this brings me to my subject — the faith that heals.
