There are two parts to the human dilemma. One is the belief that the end justifies the means. That push-button philosophy, that deliberate deafness to suffering, has become the monster in the war machine. The other is the betrayal of the human spirit: the assertion of dogma that closes the mind, and turns a nation, a civilization, into a regiment of ghosts--obedient ghosts or tortured ghosts.

To me the most interesting thing about man is that he is an animal who practices art and science and in every known society practices both together.

No science is immune to the infection of politics and the corruption of power. ... The time has come to consider how we might bring about a separation, as complete as possible, between Science and Government in all countries. I call this the disestablishment of science, in the same sense in which the churches have been disestablished and have become independent of the state.

Satire is not a social dynamite. But it is a social indicator: it shows that new men are knocking at the door.

By the worldly standards of public life, all scholars in their work are of course oddly virtuous. They do not make wild claims, they do not cheat, they do not try to persuade at any cost, they appeal neither to prejudice nor to authority . . .

Man masters nature not by force but by understanding. This is why science has succeeded where magic failed: because it has looked for no spell to cast over nature.

Nations in their great ages have not been great in art or science, but in art and science.
