No lesson seems to be so deeply inculcated by the experience of life as that you should never trust experts. If you believe the doctors, nothing is wholesome: if you believe the theologians, nothing is innocent: if you believe the soldiers, nothing is safe. They all require their strong wine diluted by a very large admixture of insipid common sense.
Robert Cecil, Lord Salisbury (1830-1903) British politician [Robert Gascoyne-Cecil, 3rd Marquess of Salisbury]
Letter to Lord Lytton (15 Jun 1877)
