We must remember that we do not observe nature as it actually exists, but nature exposed to our methods of perception. The theories determine what we can or cannot observe...Reality is an illusion, albeit a persistent one.
Nor do I take into account a danger of starting a chain reaction of a scope great enough to
destroy part or all of the planet...But it is not necessary to imagine the earth being destroyed like a nova by a stellar explosion to understand vividly the grow ing scope of atomic war and to recognize that unless another war is prevented it is likely to bring destruction on a scale never before held possible, and even now hardly conceived, and that little civilization would survive it.
Since I do not forsee that atomic energy is to be a great boon for a long time, I have to say that for the present it is a menace. Perhaps it is well that it should be. It may intimidate the human race into bringing order into its international affairs, which, without the presence of fear, it would not do.
