I'm not an atheist. I don't think I can call myself a pantheist. The problem involved is too vast for our limited minds. We are in the position of a little child entering a huge library filled with books in many languages. The child knows someone must have written those books.

I hate crowds and making speeches. I hate facing cameras and having to answer to a crossfire of questions. Why popular fancy should seize upon me, a scientist, dealing in abstract things and happy if left alone, is a manifestation of mass psychology that is beyond me.

The intellect has little to do on the road to discovery. There comes a leap in consciousness, call it Intuition or what you will, the solution comes to you and you don't know how or why.

The difference between what the most and the least learned people know is inexpressibly trivial in relation to that which is unknown.

What interests me most is whether God could have made the world differently.

I should very much like to remain in the darkness of not having been analyzed.

It would be better if you began to teach others only after you yourself have learned something.
