“If your family life had to be represented on stage, what kind of play would it be?” asks Eric Berne founder and creator of Transactional Analysis who through his theory of life script proposes to unravel the role taht each person takes in life. This role has been configurated through the conscious and unconscious dictates received from the mother’s womb and which men later interpret on the great stage of life, reciting their speech and relating to their couples, children, parents, friends, bosses, therapy partners and therapists in a parody of reality. In the second edition (reviewed and improved), the author develops a deep and didactic principle of Transactional Analysis, not only for students and professionals of mental health, to whom it is originally addressed, but also for all kinds of readers who might find it useful in their family, social, work and couple relationships and for their individual growth.
