An intelligent woman has millions of born enemies... all the stupid men.

Those who know nothing must believe everything.

Have patience with the quarrelsomeness of the stupid. It is not easy to comprehend that one does not comprehend.

You stay young as long as you can learn, acquire new habits, and suffer contradictions.

With our parents we bury our past, with our children our future.

That bad manners are so prevalent in the world is the fault of good manners.

If you have one good idea, people will lend you twenty.
