“Darkness cannot drive out darkness: only light can do that. Hate cannot drive out hate: only love can do that.”

“I am convinced that love is the most durable power in the world. It is not an expression of impractical idealism, but of practical realism. Far from being the pious injunction of a Utopian dreamer, love is an absolute necessity for the survival of our civilization. To return hate for hate does nothing but intensify the existence of evil in the universe. Someone must have sense enough and morality enough to cut off the chain of hate and evil, and this can only be done through love.” — Martin Luther King Jr.”

“But it is not enough for me to stand before you tonight and condemn riots. It would be morally irresponsible for me to do that without, at the same time, condemning the contingent, intolerable conditions that exist in our society. These conditions are the things that cause individuals to feel that they have no other alternative than to engage in violent rebellions to get attention. And I must say tonight that a riot is the language of the unheard. And what is it America has failed to hear? It has failed to hear that the plight of the negro poor has worsened over the last twelve or fifteen years. It has failed to hear that the promises of freedom and justice have not been met. And it has failed to hear that large segments of white society are more concerned about tranquility and the status quo than about justice and humanity.”

“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.”

“The time has come for an all-out war against poverty. The rich nations must use their vast resources of wealth to develop the underdeveloped, school the unschooled, and feed the unfed. Ultimately a great nation is a compassionate nation. No individual or nation can be great if it does not have a concern for "the least of these".”

“Si supiera que el mundo se acaba mañana, yo, hoy todavía, plantaría un árbol.”

“A man dies when he refuses to stand up for that which is right.”

“unearned suffering is redemptive.”

“An individual has not started living until he can rise above the narrow confines of his individualistic concerns to the broader concerns of all humanity.”

“Nothing in all the world is more dangerous than sincere ignorance and conscientious stupidity.”

“Those who love peace must learn to organize as effectively as those who love war.”

“We were all involved in the death of John Kennedy. We tolerated hate; we tolerated the sick stimulation of violence in all walks of life; and we tolerated the differential application of law, which said that a man's life was sacred only if we agreed with his views. This may explain the cascading grief that flooded the country in late November. We mourned a man who had become the pride of the nation, but we grieved as well for ourselves because we knew we were sick.”

“The true measure of a man is not how he behaves in moments of comfort and convenience but how he stands at times of controversy and challenges.”

“I could never again raise my voice against the violence of the oppressed, without having first spoken clearly to the greatest purveyor of violence in the world today – my own government.”

“There can be no deep disappointment where there is not deep love.”
