The role of the third party is often played by a material or psychic object or by a living being, then called the ÂsubjectÂ. The third party enables relationships, especially in education. According to Michel Vial, Âthe third object is a medium that sends the subject back to themself and allows them to work on their change, to regulate themself, to evaluate themselfÂ. If the object can exercise the role of the third party in interpersonal or intrapersonal relations, it is always the subject and the subjectÂs relationship with another human being, or with the group, that benefits or suffers from it. Paradoxically, it may well be that the condition of possibility enabling the process of personification is the third party, the Ânon-personÂ, as Benveniste claimed.

This book is intended for relationship professionals, educators, parents, teachers, facilitators and trainers, as well as caregivers and therapists, in order to help them understand the issue of the third party
