“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.”
― Frederick Douglass, Frederick Douglass: Selected Speeches and Writings

“If I have seen further it is by standing on the shoulders of Giants.”
― Isaac Newton, The Correspondence of Isaac Newton: Volume 5, 1709–1713

“If only it were all so simple! If only there were evil people somewhere insidiously committing evil deeds, and it were necessary only to separate them from the rest of us and destroy them. But the line dividing good and evil cuts through the heart of every human being. And who is willing to destroy a piece of his own heart?”
― Aleksandr Solzhenitsyn, The Gulag Archipelago 1918–1956

“It is the mark of an educated mind to be able to entertain a thought without accepting it.”
― Aristotle, Metaphysics
