“There have been those who magnificently dared. There have been bearers of the truth, men who groped in the world's tumult, trying to make plain order of it. They discover what we did not yet know; chiefly they discover what we no longer knew.”

1950s, Give Us the Ballot (1957)
Context: This is no day for the rabble-rouser, whether he be Negro or white. We must realize that we are grappling with the most weighty social problem of this nation, and in grappling with such a complex problem there is no place for misguided emotionalism. We must work passionately and unrelentingly for the goal of freedom, but we must be sure that our hands are clean in the struggle. We must never struggle with falsehood, hate, or malice. We must never become bitter. I know how we feel sometime. There is the danger that those of us who have been forced so long to stand amid the tragic midnight of oppression—those of us who have been trampled over, those of us who have been kicked about—there is the danger that we will become bitter. But if we will become bitter and indulge in hate campaigns, the new order which is emerging will be nothing but a duplication of the old order.

1950s, Loving Your Enemies (November 1957)
Variant: We must discover the power of love, the power, the redemptive power of love. And when we discover that we will be able to make of this old world a new world. We will be able to make men better. Love is the only way.
Context: But there is another way. And that is to organize mass non-violent resistance based on the principle of love. It seems to me that this is the only way as our eyes look to the future. As we look out across the years and across the generations, let us develop and move right here. We must discover the power of love, the power, the redemptive power of love. And when we discover that we will be able to make of this old world a new world. We will be able to make men better. Love is the only way.

"The End and the Beginning"
Poems New and Collected (1998), The End and the Beginning (1993)
Context: Those who knew
what this was all about
must make way for those
who know little.
And less than that.
And at last nothing less than nothing.
