The guidelines followed by many educational boards recommend behavioristic practices for dealing with student discipline; however, Lawrence Kohlberg's idea of organizing schools as "just communities" suggests a more promising approach. It translates to the school context the core principle of Habermas's discourse ethics: "those norms to which all concerned agree are valid." In such democratically organized schools, students engage in less violence and take greater responsibility for safeguarding each other's welfare. Public debates about rules and handling transgressions generate knowledge regarding shared norms, promote role-taking abilities, and foster ego-syntonic commitment to democratic values. Such participatory experiences may contribute to constituting ego identity. Whereas identity politics relies on particularistic affiliations and emphasizes demarcations between social groups, ego identity is based on a commitment to universal moral values. This commitment allows individuals to develop and sustain a sense of coherence, continuity, and uniqueness, and it fosters democratic cooperation and social cohesion. In this article, Gertrud Nunner-Winkler provides empirical support for these claims.
