With the past, I have nothing to do nor with the future. I live now.

Life consists in what a man is thinking of all day.

To know even one life has breathed easier because you have lived. This is to have succeeded.

A chief event of life is the day in which we have encountered a mind that startled us.

It is one of the beautiful compensations in this life that no one can sincerely try to help another without helping himself.

He who is not everyday conquering some fear has not learned the secret of life.

Don't be too timid and squeamish about your actions. All life is an experiment.

A man is a god in ruins. When men are innocent, life shall be longer, and shall pass into the immortal, as gently as we awake from dreams.

As soon as there is life there is danger.

People disparage knowing and the intellectual life, and urge doing. I am content with knowing, if only I could know.
