According to Kohlberg's Theory of Moral Development, how many main stages are there?

Kohlberg's Theory of Moral Development is structured around six distinct stages, which are grouped into three main levels: pre-conventional, conventional, and post-conventional. These levels represent a progression of moral reasoning from a self-centered understanding of morality to a greater consideration for societal values and universal ethical principles. While several theories outline different stages or dimensions of moral reasoning, the understanding of three main levels is critical in grasping the broader framework of Kohlberg’s theory. Therefore, identifying the three main levels is key to understanding the stages of moral development rather than emphasizing a specific number of stages, which could lead to confusion.
