Albert Schweitzer

We live in a dangerous era. Humanity has learned to dominate nature long before it has learned to control itself.

The years may wrinkle the skin, but giving up enthusiasm wrinkles the soul.

Pain is for humanity a tyrant more terrible than death.

As we acquire knowledge, things do not become more understandable, but more mysterious.

At twenty years of age, everyone has the face that God gave them; at forty, the face that life has given them, and at sixty, the face they deserve.

Fear reigns over life.

To the question of whether I am optimistic or pessimistic, I respond that my knowledge is pessimistic, but my will and hope are optimistic.

The purpose of human life is to serve, show compassion, and have the will to help others.

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