"We have to find a way to reconcile our scientific progress with our moral responsibility."

"We have to find a way to build a better world, a world where the atomic bomb is no longer a threat."

"We must be prepared to make the effort to understand the world, and to live in it as human beings."

"We knew the world would not be the same. A few people laughed, a few people cried, most people were silent."

"We have made a rod for our own backs."
