The author gives an overview of the two types of morality and two types of educational relation in Piaget's theory. Korthals states that the two types of morality are adult constraint and cooperation, each one being on the complete opposite end of the other with many different combinations in between. Adult constraint he mentions as being that of a unilateral respect in which a child is motivated to obey an adult. He gives an example of an older person saying what should be done and showing that they care about that child, therefore the child is obeying the adult. Cooperation is then the complete opposite and involves mutual respect in which both participants are motivated equally. Korthals example for this instance is the way two actors relate to and appreciate one another. He then goes on to tell of the two types of educational relation. The first being asymmetrical interaction which occurs in the first years. Korthals explains that the spontaneous and unconscious selfishness of a child brings forth moral realism. During this stage the child grasps the concept of rules and an obligation to follow them. The second stage is when autonomy is reached. According to Piaget, this is when one places themselves at equality with the child and tries to discuss rules and figure out why they are legitimate. The author is clear in discussing each of these points and correlating them to their dealings with parents, teachers and children.
