The present article aims to explore, based on Lawrence Kohlberg's theory of the moral stages, some of the ethical alternatives that arise from its approaches. Adopting most of its premises and leaving aside some notorious reviews of his system (Carol Gilligan), our intention is to try to lead his conclusions to the ultimate consequences. For that purpose we will first relate it to Habermas's theory of communicative action, secondly to the general judgement concept of Thomas Nagel, and finally, to the ethical skepticism of John Leslie Mackie, always pointing out the recreational dimension of the moral conscience.
