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

I am enough of an artist to draw freely upon my imagination.

When I have one week to solve a seemingly impossible problem, I spend six days defining the problem. Then, the solution becomes obvious.

One should respect an honest person even if he expresses opinions differing from one's own.

Dear Posterity, If you have not become more just, more peaceful, and in general more sensible... then may the Devil take you!

I know quite certainly that I myself have no special talent; curiosity, obsession and dogged endurance, combined with self-criticism, have brought me to my ideas.

From the viewpoint of a Jesuit priest I am, of course, and have always been an atheist.
