Power at its best is love implementing the demands of justice.
Justice at its best is love correcting everything that stands against love.

Martin Luther King, Jr., Where Do We Go from Here: Chaos or Community?, 1967.

Man is man because he is free to operate within the framework of his destiny. He is free to deliberate, to make decisions, and to choose between alternatives. He is distinguished from animals by his freedom to do evil or to do good and to walk the high road
of beauty or tread the low road of ugly degeneracy.

Rev. Martin Luther King, Jr., The Measures of Man, 1959.

If a man hasn’t discovered something that he will die for, he isn’t fit to live.

Martin Luther King, Jr., speech, Detroit, Michigan, June 23, 1963.
