Why is it I always get my best ideas while shaving?

What humanity owes to personalities like Buddha, Moses, and Jesus ranks for me higher than all the achievements of the enquiring and constructive mind.

Understanding of our fellow human beings...becomes fruitful only when it is sustained by sympathetic feelings in joy and sorrow.

The faster you go, the shorter you are.

I think that only daring speculation can lead us further and not accumulation of facts.

I never made one of my discoveries through the process of rational thinking

I do know that kind fate allowed me to find a couple of nice ideas after many years of feverish labor.
