History is the memory of things said and done.

The logic of all this seems to be that it is all right for young people in a democracy to learn about any civilization or social theory that is not dangerous, but that they should remain entirely ignorant of any civilization or social theory that might be dangerous on the ground that what you don't know can't hurt you ... a complete denial of the democratic principle that the general diffusion of knowledge and learning through the community is essential to the preservation of free government.

My own mind is my own church.

No class of Americans, so far as I know, has ever objected . . . to any amount of governmental meddling if it appeared to benefit that particular class.

Serious thinkers are few, and the world is ruled by crude ideas.

Corporations have at different times been so far unable to distinguish freedom of speech from freedom of lying that their freedom has to be curbed.

No one can deny that much of our modern advertising is essentially dishonest; and it can be maintained that to lie freely and all the time for private profit is not to abuse the right of free speech, whether it is a violation of the law or not. But again the practical question is, how much lying for private profit is to be permitted by law?
