Everything is not as good as in El-Dorado; but everything is not so bad.

Those who can make you believe absurdities can make you commit atrocities.

Whatever you do, crush the infamous thing, and love those who love you.

Shun idleness. It is rust that attaches itself to the most brilliant metals.

There is only one morality, as there is only one geometry.

My life's dream has been a perpetual nightmare.

Liberty of thought is the life of the soul.

The ear is the avenue to the heart.

Who are you, Nature? I live in you; for fifty years I have been seeking you, and I have not found you yet.
