If we could give every individual the right amount of nourishment and exercise, not too little and not too much, we would have found the safest way to health.
HippocratesThe function of protecting and developing health must rank even above that of restoring it when it is impaired.
HippocratesThere are some arts which to those that possess them are painful, but to those that use them are helpful, a common good to laymen, but to those that practise them grievous. Of such arts there is one which the Greeks call medicine. For the medical man sees terrible sights, touches unpleasant things, and the misfortunes of others bring a harvest of sorrows that are peculiarly his; but the sick by means of the art rid themselves of the worst of evils, disease, suffering, pain and death.
