From an introduction written by Edward Teller

"Man is not wicked; man is not perfect. He is at his best

when his actions are closely related to his own affairs and

his own firm knowledge. He is at his worst when he tries to

interfere with others, particularly in matters where his information

is deficient; then he is led too easily into exaggerations;

there is no check, no bridle on his actions that are

leading him ever toward more power. It is probable that

power corrupts; it is certain that knowledge purifies. In his

own affairs, a man is apt to have more knowledge. In matters

of science and technology, there are sharp limitations

imposed by proven facts of wide validity. These are some of

the important advantages of private decisions and of expert

judgments."
