“Without a struggle, there can be no progress.”

“There can be no progress without head-on confrontation.”

“If there is no struggle, there is no progress. Those who profess to favor freedom, and yet depreciate 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.”

“Without a sense of identity, there can be no real struggle.”

“People who want a cure, provided they can have it without pain, are like those who favour progress, provided they can have it without change.”

“Although there is no progress without change, not all change is progress.”
