The means by which we live have outdistanced the ends for which we live. Our scientific power has outrun our spiritual power. We have guided missiles and misguided men. – Martin Luther King,Jr., Strength to Love, 1963

A world war – God forbid! – will leave only smoldering ashes as a mute testimony of a human race whose folly led inexorably to untimely death. Yet there are those who sincerely feel that disarmament is an evil and international negotiation is an abominable waste of time. – Martin Luther King,Jr., Strength to Love, 1963
I would be the last to condemn the thousands of sincere and dedicated people outside the churches who have labored unselfishly through various humanitarian movements to cure the world of social evils, for I would rather a man be a committed humanist than an uncommitted Christian. – Martin Luther King,Jr., Strength to Love, 1963
The oceans of history are made turbulent by the ever-rising tides of hate. History is cluttered with the wreckage of nations and individuals that pursued that self-defeating path of hate. Love is the key to the solution of the problems of the world. – Martin Luther King,Jr., Nobel Prize lecture, 11 December 1968
