My feeling is that as far as creativity is concerned, isolation is required. Creation is embarrassing. For every new good idea you have, there are a hundred, ten thousand foolish ones.

I'm not a speed reader. I'm a speed understander.

Despite all that education and experience can do, I retain a certain level of unsophistication that I cannot eradicate and that my friends find amusing.

I suspect that I am never quite as unsophisticated as they think I am, but I don't mind.

Once, when a religionist denounced me in unmeasured terms, I sent him a card saying, "I am sure you believe that I will go to hell when I die, and that once there I will suffer all the pains and tortures the sadistic ingenuity of your deity can devise and that this torture will continue forever. Isn't that enough for you? Do you have to call me bad names in addition?"

Man's greatest asset is the unsettled mind.
