To the average man, life presents itself, not as material malleable to his hand, but as a series of problems...which he has to solve...And he is distressed to find that the more means he can dispose of-such as machine-power, rapid transport, and general civilized amenities, the more his problems grow in hardness and complexity....Perhaps the first thing he can learn form the artists is that the only way of 'mastering' one's material is to abandon the whole conception of mastery and to co-operate with it in love: whosoever will be a lord of life, let him be its servant.

The only ethical principle which has made science possible is that the truth shall be told all the time. If we do not penalize false statements made in error, we open up the way for false statements by intention. And a false statement of fact, made deliberately, is the most serious crime a scientist can commit.

the heaviest restriction upon the freedom of public opinion is not the official censorship of the Press, but the unofficial censorship by a Press which exists not so much to express opinion as to manufacture it.

While time lasts there will always be a future, and that future will hold both good and evil, since the world is made to that mingled pattern.

The great advantage about telling the truth is that nobody ever believes it.

No, no, there must be a limit to the baseness even of publishers.
