The first gulp from the glass of natural sciences will turn you into an atheist, but at the bottom of the glass God is waiting for you.
What we observe is not nature itself, but nature exposed to our method of questioning.
There are things that are so serious that you can only joke about them.
The reality we can put into words is never reality itself.
An expert is someone who knows some of the worst mistakes that can be made in his subject, and how to avoid them.

If we omitted all that is unclear, we would probably be left completely uninteresting and trivial tautologies.
