The human spirit is not dead.  It lives on in secret…. It has come to believe that compassion, in which all ethics must take root, can only attain its full breadth and depth if it embraces all living creatures and does not limit itself to mankind.  ~Albert Schweitzer, Novel Peace Prize address, "The Problem of Peace in the World Today"quoted in Joanne Stepaniak, The Vegan Sourcebook, 1998
