It was quite incomprehensible to me… why in my evening prayers I should pray for human beings only. So when my mother had prayed with me and had kissed me goodnight, I used to add silently a prayer that I had composed myself for all living creatures. It ran thus: "O Heavenly Father, protect and bless all things that have breath; guard them from all evil, and let them sleep in peace. "
—Albert Schweitzer
There are too many people, and too few human beings.
