Human is both a biological and a social being. As they grow old, they become a person, that is, to a greater extent social. In developing, we acquire social thinking, which is main goal at learning about social reality, that is, at other people, social groups, and relationships. Learning itself helps to develop social thinking. Social thinking is necessary for socialization.

According to Stanislas Dehaene, the specificity of human beings is that this is the only species who teaches its offspring and tests the effectiveness of learning. Children comprehend the material much better, when a teacher leads and, if necessary, explains with examples, than when they are their own teachers.
