Martin Luther King, Jr. Quote

Third we must not seek to defeat or humiliate the enemy but to win his friendship and understanding. At times we are able to humiliate our worst enemy. Inevitably, his weak moments come and we are able to thrust in his side the spear of defeat. But this we must not do. Every word and deed must contribute to an understanding with the enemy and release those vast reservoirs of goodwill which have been blocked by impenetrable walls of hate.

Loving Your Enemies (Christmas 1957)
