Again, faith is the cement which binds man to man in every relation of life. Without faith in the Editor of the _Journal_ I would not have accepted his invitation to write this brief note, and he had confidence that I would not write rubbish. Personally I have battened on it these thirty-six years, ever since the McGill Medical Faculty gave me my first mount. I have had faith in the profession, the most unbounded confidence in it as one of the great factors in the progress of humanity; and one of the special satisfactions of my life has been that my brethren have in many practical ways shown faith in me, often much more than (as I know in my heart of hearts) I have deserved. I take this illustration of the practical value of the faith that worketh confidence, but there is not a human relationship which could not be used for the same purpose. And a third aspect is one of very great importance to the question in hand--a man must have faith in himself to be of any use in the world. There may be very little on which to base it--no matter, but faith in one’s powers, in one’s mission, is essential to success. Confidence once won, the rest follows naturally; and with a strong faith in himself a man becomes a local centre for its radiation. St. Francis, St. Theresa, Ignatius Loyola, Florence Nightingale, the originator of every cult or sect or profession, has possessed this infective faith. And in the ordinary everyday work of the doctor, confidence, assurance (in the proper sense of the word) is an asset without which it is very difficult to succeed. How often does one hear the remark, ‘Oh! he does not inspire confidence,’ or the reverse! How true it is, as wise old Burton says: ‘That the patient must have a sure hope in his physician. Damascen, the Arabian, requires likewise in the physician himself that he be confident he can cure him, otherwise his physic will not be effectual, and promise withal that he will certainly help him, make him believe so at least. Galeottus gives this reason because the form of health is contained in the physician’s mind, and as Galen holds confidence and hope to be more good than physic, he cures most in whom most are confident’; and he quotes Paracelsus to the effect that Hippocrates was so fortunate in his cures not from any extraordinary skill, but because ‘the common people had a most strong conceit of his worth.’ 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.
