The extreme danger to mankind inherent in the proposal [to develop thermonuclear weapons] wholly outweighs any military advantage. - Robert Oppenheimer

There are no secrets about the world of nature. There are secrets about the thoughts and intentions of men.

Much has been said of the prospect that man, along with many other forms of life...would disappear as a species. In time, not a long time, that may come to be possible. What is more certain and more immediate is that we would lose much of our human inheritance, much that has made our civilization and our humanity...the threat of the apocalypse will be with us for a long time; the apocalypse may come.

The general notions about human understanding ... which are illustrated by discoveries in atomic physics are not in the nature of things wholly unfamiliar, wholly unheard of, or new. Even in our own culture, they have a history, and in Buddhist and Hindu thought a more considerable and central place. What we shall find is an exemplification, an encouragement, and a refinement of old wisdom.
