The classical pragmatism of John Dewey, William James, and Charles Sanders Peirce has influenced research in the field of public administration. Scholars claim classical pragmatism had a profound influence on the origin of the field of public administration. At the most basic level, public administrators are responsible for making programs "work" in a pluralistic, problems-oriented environment. Public administrators are also responsible for the day-to-day work with citizens. Dewey's participatory democracy can be applied in this environment. Dewey and James' notion of theory as a tool, helps administrators craft theories to resolve policy and administrative problems. Further, the birth of American public administration coincides closely with the period of greatest influence of the classical pragmatists.
