“Is the surface of a planet really the right place for expanding technological civilization?”

The Ballot or the Bullet (1964), Speech in Cleveland, Ohio (April 3, 1964)
Context: We need to expand the civil-rights struggle to a higher level—to the level of human rights. Whenever you are in a civil-rights struggle, whether you know it or not, you are confining yourself to the jurisdiction of Uncle Sam. No one from the outside world can speak out in your behalf as long as your struggle is a civil-rights struggle. Civil rights comes within the domestic affairs of this country. All of our African brothers and our Asian brothers and our Latin-American brothers cannot open their mouths and interfere in the domestic affairs of the United States. And as long as it’s civil rights, this comes under the jurisdiction of Uncle Sam. But the United Nations has what’s known as the charter of human rights; it has a committee that deals in human rights. You may wonder why all of the atrocities that have been committed in Africa and in Hungary and in Asia, and in Latin America are brought before the UN, and the Negro problem is never brought before the UN. This is part of the conspiracy. This old, tricky blue eyed liberal who is supposed to be your and my friend, supposed to be in our corner, supposed to be subsidizing our struggle, and supposed to be acting in the capacity of an adviser, never tells you anything about human rights. They keep you wrapped up in civil rights. And you spend so much time barking up the civil-rights tree, you don’t even know there’s a human-rights tree on the same floor.

"Quotes", The Educated Imagination (1963), Talk 6: The Vocation of Eloquence
Context: The particular myth that's been organizing this talk, and in a way the whole series, is the story of the Tower of Babel in the Bible. The civilization we live in at present is a gigantic technological structure, a skyscraper almost high enough to reach the moon. It looks like a single world-wide effort, but it's really a deadlock of rivalries; it looks very impressive, except that it has no genuine human dignity. For all its wonderful machinery, we know it's really a crazy ramshackle building, and at ay time may crash around our ears. What the myth tells us is that the Tower of Babel is a work of human imagination, that tis main elements are words, and that what will make it collapse is a confusion of tongues. All had originally one language, the myth says. That language is not English or Russian or Chinese or any common ancestor, if there was one. It is the language of human nature, the language that makes both Shakespeare and Pushkin authentic poets, that gives a social vision to both Lincoln and Gandhi. It never speaks unless we take the time to listen in leisure, and it speaks only in a voice too quite for panic to hear. And then all it has to tell us, when we look over the edge of our leaning tower, is that we are not getting any nearer [to] heaven, and that it is time to return to the earth.
