This work features prominently in the systemic movement in modern psychotherapy, which can neither ignore nor the family nor the social environment. All supported therapeutic perspective on this dialectic becomes more likely to progress investigations or classical therapies, which separate the individual from his environment. In this sense the exercise of the therapist aims to solve problems or correct errors, but immersed in the mystery of the families and meeting with them. This involves passing a therapy where the therapist observes, a therapy where the therapist observes the family to relay that ability perception.
