Reverence for life affords me my fundamental principle of morality, namely that good consists in maintaining, assisting, and enhancing life, and that to destroy, to harm, or to hinder life is evil. – Albert Schweitzer

Just as white light consists of colored rays, so reverence for life contains all the components of ethics: love, kindliness, sympathy, empathy, peacefulness and power to forgive. – Albert Schweitzer
