“We think we know.""Know? That's worse than an atom bomb, and always was.”

“We always know more than we think we do. The problem is we don't always know what we know.”

“Ours is a world of nuclear giants and ethical infants. We know more about war than we know about peace, more about killing than we know about living. We have grasped the mystery of the atom and rejected the Sermon on the Mount.”

“Like the atomic bomb, it’s there; like the bomb, the temptationwill always exist to use it.There can no longer be a worldwithout the atomic bomb; there can no longer be a worldwithout violent movies.”

“and the world we live in will be either better or worse, depending on whether we become better or worse. And that's where the power of love comes in. Because when we love, we always strive to become better than we are.”

“Our opponent is an alien starship packed with atomic bombs," I said. "We have a protractor.”
