ABSTRACT
This chapter presents a few words on the social dimension in Piaget's theory. Humans are highly adapted to complex social interaction, and therefore they enter into highly complex interactions that generate a typically human social reality. For Piaget, social interaction is one important motor and cause of development. Piaget's relational position has important implications for the development of morality and rationality because different types of inter individual relationships are related to and enable or constrain specific structures of rationality and morality. The early Piaget assumed that reasoning originates in interpersonal argumentation, and autonomous morality is the product of cooperation. The explanation of morality, Piaget that the danger of sociological holism is that "it may compromise morality by identifying it with reasons of state, with accepted opinions, or with collective conservatism". The capacity for joint attention is essential for further social cognitive development, which in early childhood leads to the emergence of what has been called a "theory of mind".
