I think America has a responsibility to maintain its leadership in technology and its moral leadership in the world, to explore, to seek knowledge.

After Apollo 17, America stopped looking towards the next horizon. The United States had become a space-faring nation, but threw it away. We have sacrificed space exploration for space exploitation, which is interesting but scarcely visionary.

Today, we are on a path of decay. We are seeing the book close on five decades of accomplishment as the leader in human space exploration.

When you head on out to the Moon, in very short order, and you get a chance to look back at the Earth, that horizon slowly curves around in upon himself, and all of sudden you're looking at something that is very strange, but yet is very, very familiar, because you're beginning to see the Earth evolve.

Women ought to feel a peculiar sympathy in the colored man's wrong, for, like him, she has been accused of mental inferiority, and denied the privileges of a liberal education.

I'm forming a charitable institution for education.
