Genius is making complex ideas simple, not making simple ideas complex

People are like bicycles. They can keep their balance only as long as they keep moving.

Since that deluge of newspaper articles I have been so flooded with questions, invitations, suggestions, that I keep dreaming I am roasting in Hell, and the mailman is the devil eternally yelling at me, showering me with more bundles of letters at my head because I have not answered the old ones.

The laws of gravity cannot be held responcible for people falling in love.

You ask me if I keep a notebook to record my great ideas. I've only ever had one.

Time and space are modes by which we think and not conditions in which we live.

Feeling and longing are the motive forces behind all human endeavor and human creations.
