 Dewey returned briefly to issues of the role of art in society in The Public and its Problems (1927), where art is seen as something that can resolve the problem of dissemination of ideas appropriate for social change. Artists are the real purveyors of news insofar as they cause happenings to kindle emotion and perception. For Dewey, Walt Whitman was the exemplar of such an artist. He concludes that for a great community and a real public to come into being an art of “full and moving communication” must take possession of our mechanized world (PP: 350).
