Thick Moralities, Thin Politics grapples with the work of theorists from both sides of the Atlantic, including Jürgen Habermas, Anthony Giddens, and Niklas Luhmann, as well as George Herbert Mead, Erving Goffman, and Harold Garfinkel. Gregg develops a model of validity for arguments made in the public sphere, for understanding among competing worldviews, and for adjudicating disputes generated by normative differences. He applies his theory of politics to specific issues of contemporary social life, including those relating to the place of women, minorities, and multiculturalism in American and European society today. He also addresses the scientific study of religion, issues of legal interpretation, and the critique of ideology, in each case illuminating how different epistemic systems, as well as competing value systems, can achieve some understanding of one another. Gregg demonstrates, ultimately, that thin politics actually further, rather than reduce, citizens' engagement in the political process.
