There’s no record in the history of the Galaxy of any society being so foolish as to use nuclear explosions as a weapon of war.

There are no nations! There is only humanity. And if we don't come to understand that right soon, there will be no nations, because there will be no humanity.

At least once every human should have to run for his life, to teach him that milk does not come from supermarkets, that safety does not come from policemen, that “news” is not something that happens to other people. He might learn how his ancestors lived and that he himself is no different — in the crunch his life depends on his agility, alertness, and personal resourcefulness.
