Critiques use of postmodernism in educational sociology. Analyzes the foundations of postmodern thought, differentiating among its aesthetic, philosophical, and sociological aspects. Examines contributions of Nietzsche and other nineteenth-century romantic conservatives. Postmodern educational thought misreads global educational trends and unwittingly supports free-market policies that may increase educational inequities while failing to improve general standards.
