We know that the wages of secrecy are corruption. We know that in secrecy error, undetected, will flourish and subvert.

The physicists have known sin; and this is a knowledge which they cannot lose.

The greatest of the changes that science has brought is the acuity of change; the greatest novelty the extent of novelty.

Taken as a story of human achievement, and human blindness, the discoveries in the sciences are among the great epics.

It is perfectly obvious that the whole world is going to hell. The only possible chance that it might not is that we do not attempt to prevent it from doing so.

There must be no barriers to freedom of inquiry... There is no place for dogma in science. The scientist is free, and must be free to ask any question, to doubt any assertion, to seek for any evidence, to correct any errors. Our political life is also predicated on openness. We know that the only way to avoid error is to detect it and that the only way to detect it is to be free to inquire. And we know that as long as men are free to ask what they must, free to say what they think, free to think what they will, freedom can never be lost, and science can never regress.

We hunger for nobility: the rare words and acts that harmonize simplicity and truth.
