I know of no country in which there is so little independence of mind and real freedom of discussion as in America.

History is a gallery of pictures in which there are few originals and many copies.

I cannot help fearing that men may reach a point where they look on every new theory as a danger, every innovation as a toilsome trouble, every social advance as a first step toward revolution, and that they may absolutely refuse to move at all.

When the past no longer illuminates the future, the spirit walks in darkness.
