We are going to win our freedom because both the sacred heritage of our nation and the eternal will of the Almighty God are embodied in our echoing demands. So however difficult it is during this period, however difficult it is to continue to live with the agony and the continued existence of racism, however difficult it is to live amidst the constant hurt, the constant insult and the constant disrespect, I can still sing we shall overcome. We shall overcome because the arc of the moral universe is long but it bends towards justice.We shall overcome because Carlisle is right. No lie can live forever. We shall overcome because William Cullen Bryant is right. Truth crushed to earth will rise again. We shall overcome because James Russell Lowell is right. Truth forever on the scaffold, wrong forever on the throne.   Yet that scaffold sways the future. We shall overcome because the Bible is right.  You shall reap what you sow. With this faith we will be able to hew out of the mountain of despair, a stone of hope. With this faith we will be able to transform the jangling discords of our nation into a beautiful symphony of brotherhood. With this faith we will be able to speed up the day when all of God's children all over this nation - black men and white men, Jews and Gentiles, Protestants and Catholics will be able to join hands and sing in the words of the old negro spiritual, Free at Last, Free at Last, Thank God Almighty, We are Free At Last.

~ Martin Luther King Jr.

Struggles to coerce uniformity of sentiment in support of some end thought essential to their time and country have been waged by many good as well as by evil men. Nationalism is a relatively recent phenomenon but at other times and places the ends have been racial or territorial security, support of a dynasty or regime, and particular plans for saving souls. As first and moderate methods to attain unity have failed, those bent on its accomplishment must resort to an ever-increasing severity. . . . Those who begin coercive elimination of dissent soon find themselves exterminating dissenters. Compulsory unification of opinion achieves only the unanimity of the graveyard.It seems trite but necessary to say that the First Amendment to our Constitution was designed to avoid these ends by avoiding these beginnings. There is no mysticism in the American concept of the State or of the nature or origin of its authority. We set up government by consent of the governed, and the Bill of Rights denies those in power any legal opportunity to coerce that consent. Authority here is to be controlled by public opinion, not public opinion by authority.If there is any fixed star in our constitutional constellation, it is that no official, high or petty, can prescribe what shall be orthodox in politics, nationalism, religion, or other matters of opinion or force citizens to confess by word or act their faith therein.
