This book is the result of an academic concern that for several years has been calling for my response. Gestalt Therapy, science and life, technique and art, philosophy and attitude, had been demanding a reflection directed more towards its principles and fundamentals. This book proposes an understanding, it is not a Bible; it is a direction, not a destination; it is but a moment of creation, awaiting a new artist to come and correct, improve, and beautify the work that has been started. It is a reflection, not a presentation of methods and techniques. It is a pleasure to have finished it and it is yet a greater pleasure to see it in your hands, expecting to find out what this journey has to do with your own, so that we can, together, take further steps and create new pathways and directions for Gestalt Therapy in Brazil.
