This is probably the most famous quote by abolitionist orator Frederick Douglass:
"If there is no struggle there is no progress. Those who profess to favor freedom and yet depreciate agitation...want crops without plowing up the ground, they want rain without thunder and lightening. They want the ocean without the awful roar of its many waters.... Power concedes nothing without a demand. It never did and it never will."
Frederick Douglass, 1857
