"Now it is true that the geographic togetherness of our world has been brought into being, to a large extent, through modern man's scientific ingenuity. Modern man, through his scientific genius, has been able to dwarf distance and place time in chains. Yes, we've been able to carve highways through the stratosphere, and our jet planes have compressed into minutes distances that once took weeks and months. And so this is a small world from a geographical point of view. What we are facing today is the fact that through our scientific and technological genius we've made of this world a neighborhood. And now through our moral and ethical commitment we must make of it a brotherhood. We must all learn to live together as brothers - or we will all perish together as fools.
This is the great issue facing us today. No individual can live alone; no nation can live alone. We are tied together."
