I think that is one of the most important questions confronting our generation. As we move to make justice a reality on the international scale, as we move to make justice a reality in this nation, how will the struggle be waged? It seems to me that there are two possible answers to this question. One is to use the all to
prevalent method of physical violence. And it is true that man throughout history has sought to achieve justice through violence. And we all know the danger of this method. It seems to create many more social problems than it solves. And it seems to me that in the struggle for justice that this method is ultimately
futile. If the Negro succumbs to the temptation of using violence in his struggle for justice, unborn generations will be the recipients of a long and desolate life of bitterness, and his chief legacy to the future will be an endless reign of meaningless chaos. And there is still a voice crying into the vista of time
saying to every potential Peter put up your sword. And history is replete with the bleached bones of nations and communities that failed to follow this command.
