“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

“What is a poet? An unhappy man who hides deep anguish in his heart, but whose lips are so formed that when the sigh and cry pass through them, it sounds like lovely music.... And people flock around the poet and say: 'Sing again soon' - that is, 'May new sufferings torment your soul but your lips be fashioned as before, for the cry would only frighten us, but the music, that is blissful.”
― Soren Kierkegaard, Either - Or

“[...]the only people for me are the mad ones, the ones who are mad to live, mad to talk, mad to be saved, desirous of everything at the same time, the ones who never yawn or say a commonplace thing, but burn, burn, burn like fabulous yellow roman candles exploding like spiders across the stars and in the middle you see the blue centerlight pop and everybody goes “Awww!”
― Jack Kerouac, On the Road

“Genuine poetry can communicate before it is understood.”
― T.S. Eliot
