En 1816 se fundó la Sociedad Americana de Colonización, y se trasladó a negros a la costa de la protuberancia occidental de África; allí se fundó la … - Isaac Asimov

It is possible to be too stable. No Outer World has colonized a new planet in two and a half centuries.. are lives too long to risk and too comfortable to upset.

"I don't know about that, Dr. Fastolfe. You've come to Earth. You risk disease."

"Yes, I do. There are some of us, Mr. Baley, who feel that the future of the human race is even worth the possible loss of an extended lifetime. Too few of us, I am sorry to say."

"In trying to introduce robots here on Earth, we're doing our best to upset the balance of your City economy."

"You mean you're creating a growing group of displaced and declassified men on purpose?"

"Not out of cruelty or callousness, believe me. A group of displaced men, as you call them, are what we need to serve as a nucleus for colonization.
