What the movement proved, however, is that even if people lack the customary attributes of power-money, political authority, physical force-as did the black people of the Deep South, there is a power that can be created out of pent-up indignation, courage, and the inspiration of a common cause, and that if enough people put their minds and bodies into that cause, they can win. It is a phenomenon recorded again and again in the history of popular movements against injustice all over the world.
