I have no special talent. I am only passionately curious.

I am a deeply religious nonbeliever - this is a somewhat new kind of religion.

I am neither especially clever nor especially gifted. I am only very, very curious.

I think and think for months and years. Ninety-nine times, the conclusion is false. The hundredth time I am right.

I am a wanderer passionately in love with life.

I am not an African. I am an American.
