“The first step in the evolution of ethics is a sense of solidarity with other human beings.”

Example is not the main thing in influencing others. It is the only thing.

Happiness is nothing more than good health and a bad memory.

An optimist is a person who sees a green light everywhere, while a pessimist sees only the red stoplight.

In everyone's life, at some time, our inner fire goes out. It is then burst into flame by an encounter with another human being. We should all be thankful for those people who rekindle the inner spirit.

Man is a clever animal who behaves like an imbecile.

At times our own light goes out and is rekindled by a spark from another person.
