"Reverence for Life does not allow the scholar to live for his science alone, even if he is very useful to the community in so doing. It does not permit the artist to exist only for his art, even if he gives inspiration to many by its means. It refuses to let the business man imagine that he fulfils all legitimate demands in the course of his business activities. It demands from all that they should sacrifice a portion of their own lives for others."
- Dr. Albert Schweitzer, from Civilization and Ethics
