True literacy is becoming an arcane art, and the nation is steadily "dumbing down."

The greatest weapons in the conquest of knowledge are an understanding mind and the inexorable curiosity that drives it on.

When I sit down at the typewriter, I write. Someone once asked me if I had a fixed routine before I start, like setting up exercises, sharpening pencils, or having a drink of orange juice. I said, "No, the only thing I do before I start writing is to make sure that I'm close enough to the typewriter to reach the keys."

To introduce something altogether new would mean to begin all over, to become ignorant again, and to run the old, old risk of failing to learn.

Science doesn't purvey absolute truth. Science is a mechanism... for testing your thoughts against the universe.

The lucky few who can be involved in creative work of any sort will be the true elite of mankind, for they alone will do more than serve a machine.

There is a single light of science, and to brighten it anywhere is to brighten it everywhere.
