"It is fair to assume that Parisians would not have stormed the Bastille, Gandhi would not have challenged the empire on which the sun used not to set, Martin Luther King would not have fought white supremacy in ‘the land of the free and the home of the brave’, without their sense of manifest injustices that could be overcome. They were not trying to achieve a perfectly just world (even if there were any agreement on what that would be like), but they did want to remove clear injustices to the extent they could."
