Science seems ready to confer upon us, as its final gift, the power to erase human life from this planet.

The release of atom power has changed everything except our way of thinking... the solution to this problem lies in the heart of mankind. If only I had known, I should have become a watchmaker.

The release of atomic energy has not created a new problem. It has merely made more urgent the necessity of solving an existing one.

I do not believe that civilization will be wiped out in a war fought with the atomic bomb. Perhaps two-thirds of the people of the earth will be killed.

If men can develop weapons that are so terrifying as to make the thought of global war include almost a sentence for suicide, you would think that man's intelligence and his comprehension... would include also his ability to find a peaceful solution.

War implies a contest; when you get to the point that contest is no longer involved and the outlook comes close to destruction of the enemy and suicide for ourselves-an outlook that neither side can ignore - then arguments as to the exact amount of available strength as compared to somebody else's are no longer the vital issues.
