This document discusses Jean Piaget and Lawrence Kohlberg's theories of moral development from childhood to adulthood. According to Piaget, there are three main stages of moral development: egocentric, authoritative, and consensus. Kohlberg identified six stages of moral reasoning grouped into three levels: preconventional, conventional, and postconventional. Both theorists saw moral development as progressive and hierarchical, with individuals moving from self-interest to considering social rules and ultimately universal ethical principles.
