But merely accepting authoritarian truth, even if that truth has some virtue, does not bring skepticism to an end. To blindly accept a truth one has never reflected upon retards the advance of reason. Our world rots in deceit. . . . Just as a tree bears the same fruit year after year and at the same time fruit that is new each year, so must all permanently valuable ideas be continually created anew in thought. But our age pretends to make a sterile tree bear fruit by tying fruits of truth onto its branches.

Albert SchweitzerEthics has not only to do with mankind but with the animal creation as well. This is witnessed in the purpose of St. Francis of Assisi. Thus we shall arrive that ethics is reverence for all life. This is the ethic of love widened universally. It is the ethic of Jesus now recognized as a necessity of thought...Only a universal ethic which embraces every living creature can put us in touch with the universe and the will which is there manifest.
