All things are subject to re-formation. This is a century of life and renewal. Sciences and arts, industry and invention have been reformed. Law and ethics have been reconstituted, reorganized. The world of thought has been regenerated. Sciences of former ages and philosophies of the past are useless today. Present exigencies demand new methods of solution; world problems are without precedent. Old ideas and modes of thought are fast becoming obsolete.
