I am prejudiced in favor of him who, without impudence, can ask boldly. He has faith in humanity, and faith in himself. No one who is not accustomed to giving grandly can ask nobly and with boldness.

Johann Kaspar Lavater

To hold a pen is to be at war.

Voltaire

There is the sky, which is all men's together.

Euripides

Time is but the stream I go a-fishing in. I drink at it; but while I drink I see the sandy bottom and detect how shallow it is. Its thin current slides away, but eternity remains.

Henry David Thoreau

Never do today what you can put off till tomorrow. Delay may give clearer light as to what is best to be done.

Aaron Burr

I wrote somewhere during the Cold War that I sometimes wish the Iron Curtain were much taller than it is, so that you could see whether the development of science with no communication was parallel on the two sides. In this case it certainly wasn't.

Thomas Gold

Everything that's cool that happens, I look at my wife and I say, 'We need to enjoy this moment right here! This is really special!'

Samuel Johnson

Great things are only possible with outrageous requests.

Thea Alexander

Science is spectral analysis. Art is light synthesis.

Karl Kraus

It is not permitted to the most equitable of men to be a judge in his own cause.

Blaise Pascal

If ebooks mean that readers' freedom must either increase or decrease, we must demand the increase.

Richard Stallman
