We must never allow the voice of humanity within us to be silenced. It is humanity's sympathy with all creatures that first makes us truly human.

The greatest thing is to give thanks for everything. He who has learned this knows what it means to live. He has penetrated the whole mystery of life: giving thanks for everything.

The great secret of success is to go through life as a person who never gets used up. That is possible for those who never argue and strive with people and facts, but in all experience retires upon themselves, and look for the ultimate cause of things in themselves.

In resigning ourselves to our fate without a struggle, we are guilty of inhumanity.

By respect for life we become religious in a way that is elementary, profound and alive. Impart as much as you can of your spiritual being to those who are on the road with you, and accept as something precious what comes back to you from them. 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. - Albert Schweitzer
