“Deep at the dark bottom of the melting pot, where the private is public and the public private, where black is white and white black, where the immoral becomes moral and the moral is anything that makes one feel good (or that one has the power to sustain), the white man's relish is apt to be the black man's gall.”
"Change the Joke and Slip the Yoke" (1958), in The Collected Essays, ed. John F. Callahan (New York: Modern Library, 1955), p. 104.

Address on the anniversary of the birth of Martin Luther King (15 January 1983) http://www.reagan.utexas.edu/archives/speeches/1983/11583d.htm

Context: Abraham Lincoln freed the black man. In many ways, Dr. King freed the white man. How did he accomplish this tremendous feat? Where others — white and black — preached hatred, he taught the principles of love and nonviolence. We can be so thankful that Dr. King raised his mighty eloquence for love and hope rather than for hostility and bitterness. He took the tension he found in our nation, a tension of injustice, and channeled it for the good of America and all her people.
