Piaget and Kohlberg both thought that parents and other authorities were obstacles to moral development. If you want your kids to learn about the physical world, let them play with cups and water; don’t lecture them about the conservation of volume. And if you want your kids to learn about the social world, let them play with other kids and resolve disputes; don’t lecture them about the Ten Commandments. And, for heaven’s sake, don’t force them to obey God or their teachers or you. That will only freeze them at the conventional level.
