The world is the work of a single thought, expressed in a thousand different ways.

Enthusiasm gives life to what is invisible; and interest to what has no immediate action on our comfort in this world.

A man must know how to fly in the face of opinion; a woman to submit to it.

The greatest happiness is to transform one's feelings into action.

Unhappy love freezes all our affections: our own souls grow inexplicable to us. More than we gained while we were happy we lose by the reverse.

Who understands much forgives much. To understand everything makes us very forgiving.

It is difficult to grow old gracefully.
