In this fascinating study, Naranjo has captured the flavour and distinctive character of the California-based school of Gestalt therapy, propagated by Perls in his last years as a teacher and exemplar of the approach he pioneered. Lively and highly readable, learned and insightful, this book is indispensable both for professionals and the lay-reader in demonstrating why Fritz Perls was truly the father of the now-flourishing human potential movement.
