Once a man recognizes himself as a being surrounded by other beings in this world and begins to respect his life and take it to the highest value, he becomes a thinking being. Then he values other lives and experiences them as part of his own life. With that, his goal is to help everyone take their life to the highest value; anything which limits or destroys a life is evil. That is morality. That is how men are related to the world around them.
Albert SchweitzerThought cannot avoid the ethical or reverence and love for all life. It will abandon the old confined systems of ethics and be forced to recognize the ethics that knows no bounds. But on the other hand, those who believe in love for all creation must realize clearly the difficulties involved in the problem of a boundless ethic and must be resolved not to veil from humankind the conflicts which this ethic will involve us, but allow us really to experience them. To think out in every implication the ethic of love for all creation this is the difficult task which confronts our age.
Albert SchweitzerAffirmation of the world, which means affirmation of the will-to-live that manifests itself around me, is only possible if I devote myself to other life.
