My own mind is my own church.

The value of history is, indeed, not scientific but moral: by liberalizing the mind, by deepening the sympathies, by fortifying the will, it enables us to control, not society, but ourselves - a much more important thing; it prepares us to live more humanely in the present and to meet rather than to foretell the future.

History is the memory of things said and done.

Reason is incompetent to answer any fundamental question about God, or morality, or the meaning of life.

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?

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.

To ask whether the natural rights philosophy of the Declaration of Independence is true or false, is essentially a meaningless question.
