"Through our scientific and technological genius, we have made of this world a neighborhood and yet we have not had the ethical commitment to make of it a brotherhood. But somehow, and in some way, we have got to do this. We must all learn to live together as brothers or we will all perish together as fools. We are tied together in the single garment of destiny, caught in an inescapable network of mutuality. And whatever affects one directly affects all indirectly. For some strange reason I can never be what I ought to be until you are what you ought to be. And you can never be what you ought to be until I am what I ought to be. This is the way God’s universe is made; this is the way it is structured."
MLK Sermon Delivered at the National Cathedral, Washington, D.C., on 31 March 1968. Congressional Record, 9 April 1968.
