This monograph takes us to aspects of the child's universe, in Jungian psychology, reading the concept of the child implicit in the work, addressing education in the family and at school, and the implications arising from these in the individual's life, that is, in the way he builds and deals with his inner child, in the expression of his playful soul, or in his repression, constituting a dark side of difficult access, which can generate pathologies, both in childhood, in adolescence, or in adulthood. We concluded the research considering that this theme goes beyond the borders of the family and the school, referring to the contemporary man and the psychology of personality development of Carl Gustav Jung.
