Everything that is really great and inspiring is created by the individual who can labor in freedom.

This is too difficult for a mathematician. It takes a philosopher. The hardest thing in the world to understand is the income tax.

What the individual can do is to give a fine example, and to have the courage to uphold ethical values .. in a society of cynics.

We cannot solve our problems with the same thinking we used when we created them. A question that sometimes drives me hazy: am I or are the others crazy? Any intelligent fool can make things bigger and more complex... It takes a touch of genius - and a lot of courage to move in the opposite direction. All religions, arts and sciences are branches of the same tree. It's not that I'm so smart, it's just that I stay with problems longer.
