With the fearful strain that is on me night and day, if I did not laugh I should die.

I decided to sell my drawings. However, I didn't want people to buy my drawings because the professor of physics isn't supposed to be able to draw - isn't that wonderful - so I made up a false name.

I knew I belonged to the public and to the world, not because I was talented or even beautiful, but because I had never belonged to anything or anyone else.

When Britain and the U.S. invaded Iraq, it was with the reasonable expectation that it was going to increase the threat of terror, as it has.

Man is the only creature that refuses to be what he is.
