He should sweep streets so well that all the hosts of heaven and Earth will pause to say, Here lived a great streetsweeper who did his job well. – Martin Luther King,Jr.

I still have a dream today that one day war will come to an end, that men will beat their swords into plowshares and their spears into pruning hooks, that nations will no longer rise up against nations, neither will they study war any more. – Martin Luther King,Jr., The Trumpet of Conscience, 1968
