The Europeans are all deeply tainted with prejudices, both ecclesiastical and temporal, which they can never get rid of. They are all infected with episcopal and presbyterian creeds, and confessions of faith. They all believe that great Principle which has produced this boundless universe, Newton's universe and Herschell's universe, came down to this little ball, to be spit upon by Jews. And until this awful blasphemy is got rid of, there never will be any liberal science in the world.
