Churchill on rule by experts

"Nothing would be more fatal than for the Government of States to get in the hands of experts. Expert knowledge is limited knowledge, and the unlimited ignorance of the plain man who knows where it hurts is a safer guide than any rigorous direction of a specialized character.

Sir Winston Churchill

This reminds me of the words I quoted not long ago from Lord Salisbury:

"No lesson seems to be so deeply inculcated by the experience of life as that you should never trust experts. If you believe doctors, nothing is wholesome: if you believe the theologians, nothing is innocent: if you believe the soldiers, nothing is safe."
