Morality as a guiding principle for action allows for various approaches, thus suggesting an interdisciplinary treatment of the problem. This essay focus on four of such approaches: the philosophical (Kant’s), the sociological (Durkheim’s), the psychogenetic (Kohlberg’s) and the discoursive (Habermas’s) ones. The cleavage that orients this selection and defines the themes for analysis is Piaget’s genetic structuralism, which provides the necessary elements to adequately grasp the problem as a whole. Genetic structuralism is based on reason, includes society in the reflexive process, recreates the genesis of judgement and considers discourse as a fundamental element. Thus Piaget finds support in Kant, takes Durkheim into account, sets the ground for Kohlberg and antecipates Habermas’s theorization.
