It is the mark of a truly intelligent person to be moved by statistics.

Small minds are concerned with the extraordinary, great minds with the ordinary.

I'm not the smartest fellow in the world, but I can sure pick smart colleagues.

The surest sign that intelligent life exists elsewhere in the universe is that it has never tried to contact us.

I'm an optimist in the sense that I believe humans are noble and honorable, and some of them are really smart. I have a very optimistic view of individuals.
