“Injustice anywhere is a threat to justice everywhere. Therefore, no American can afford to be apathetic about the problem of racial justice. It is a problem that meets every man at his front door.”

1960s, Letter from a Birmingham Jail (1963)
Variant: It really boils down to this: that all life is interrelated. We are all caught in an inescapable network of mutuality, tired into a single garment of destiny. Whatever affects one destiny, affects all indirectly.

Context: Injustice anywhere is a threat to justice everywhere. We are caught in an inescapable network of mutuality, tied in a single garment of destiny. Whatever affects one directly, affects all indirectly. Never again can we afford to live with the narrow, provincial "outside agitator" idea. Anyone who lives inside the United States can never be considered an outsider anywhere within its bounds.

As long as one person suffers unjustly, the whole world suffers. The existence of injustice, violence, and exploitation contaminates and diminishes the whole human community.

Now is the Time to Prevent a Third World War (1950)
Context: World government must progressively be established, common problems must be solved by common action, economic and racial justice and fellowship must be achieved... empires must be transformed into commonwealths, the race of armaments must be stopped and the system of balance-of-armed-power must be brought to an end, the churches must take Jesus seriously by trusting goodwill and pacific means and by disentangling themselves from the war system, a mighty movement of peoples must be created so that governments will maintain friendly and cooperative relations and will refrain from hostile and provocative actions.... Now is the time to prevent a third world war.

Lecture at Princeton University, Princeton, New Jersey (March 1954); published in “The Unifying Factor” in Realities of American Foreign Policy (1954), p. 116
Context: Now this problem of the adjustment of man to his natural resources, and the problem of how such things as industrialization and urbanization can be accepted without destroying the traditional values of a civilization and corrupting the inner vitality of its life — these things are not only the problems of America; they are the problems of men everywhere. To the extent that we Americans become able to show that we are aware of these problems, and that we are approaching them with coherent and effective ideas of our own which we have the courage to put into effect in our own lives, to that extent a new dimension will come into our relations with the peoples beyond our borders, to that extent, in fact, the dreams of these earlier generations of Americans who saw us as leaders and helpers to the peoples of the world at large will begin to take on flesh and reality.
