 Thus, the main focus of Dewey’s social ethics concerns the institutional arrangements that influence the capacity of people to conduct moral inquiry intelligently. Two social domains are critical for promoting this capacity: schools, and civil society.  Both needed to be reconstructed so as to promote experimental intelligence and wider sympathies. Dewey wrote numerous works on education, and established the famous Laboratory School at the University of Chicago to implement and test his educational theories. He was also a leading advocate of the comprehensive high school, as opposed to separate vocational and college preparatory schools. This was to promote the social integration of different economic classes, a prerequisite to enlarging their mutual understanding and sympathies. Civil society, too, needed to be reconstructed along more democratic lines. This involved not just expanding the franchise, but improving the means of communication among citizens and between citizens and experts, so that public opinion could be better informed by the experiences and problems of citizens from different walks of life, and by scientific discoveries (PP).  Dewey regarded democracy as the social embodiment of experimental intelligence informed by sympathy and respect for the other members of society (DE 3, 89–94). Unlike dictatorial and oligarchic societies, democratic ones institutionalize feedback mechanisms (free speech) for informing officeholders of the consequences for all of the policies they adopt, and for sanctioning them (periodic elections) if they do not respond accordingly.
