Frederick Douglass (1)
"If there is no struggle, there is no progress. ... 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 (African-American social reformer, Abolitionist movement leader, Suffragist, writer (especially anti-slavery), orator, statesman/diplomat ((born 1818, died 1895))
