It is a sad fact that because of comfort, complacency, a morbid fear of communism, and our proneness to adjust to injustice, the Western nations that initiated so much of the revolutionary spirit of the modern world have now become the arch-antirevolutionaries. – Martin Luther King,Jr., The Trumpet of Conscience, 1968

Will we march only to the music of time, or will we, risking criticism and abuse, march to the soul-saving music of eternity? – Martin Luther King,Jr., Strength to Love, 1963

Not only must we be good, but we must also be good for something. – Henry David Thoreau
