I have never looked upon ease and happiness as ends in themselves. This ethical basis I call the ideal of the pigsty.

What is essential in the life of a man of my kind is what he thinks and how he thinks, and not what he does or suffers.

My life is a simple thing that would interest no one. It is a known fact that I was born, and that is all that is necessary.

I like to experience the universe as one harmonious whole. Every cell has life. Matter, too, has life; it is energy solidified. Our bodies are like prisons, and I look forward to be free, but I don't speculate on what will happen to me. I live here now, and my responsibility is in this world now.

A true genius admits that he/she knows nothing.

Gravity is a response to geometry.

It is my fate to be considered an authority, since I spent my youth rebelling against it.
