"It is a matter of profound gravity that the world has changed, and we must change with it."

"I carry a great burden of responsibility."

"The only way to make sense out of change is to plunge into it, move with it, and join the dance."

"Now I am become Death, the destroyer of worlds."

"We have to learn to live with the knowledge that we have the power to destroy ourselves, but also the power to save ourselves."
