Those who profess to favor freedom, yet deprecate agitation, are men who want crops without plowing up the ground. They want rain without thunder and lightning. They want the ocean without the awful roar of its many waters. This struggle may be a moral one or it may be a physical one; or it may be both moral and physical; but it must be a struggle. Power concedes nothing without a demand. It never did and it never will.
-- Frederick Douglass
Of liberty I would say that, in the whole plenitude of its extent, it is unobstructed action according to our will. But rightful liberty is unobstructed action according to our will within limits drawn around us by the equal rights of others. I do not add “within the limits of the law,” because law is often but the tyrant's will, and always so when it violates the right of an individual.
--Thomas Jefferson to Isaac H. Tiffany, 1819
