Book excerpt: What happens to the thinking of a thinker who refuses a discipleship? This book attempts to answer this question in relation to D. W. Winnicott and the evolution of his thinking. He eschewed a following, privileging the independence of his thinking and fostering the same in others. However Winnicott's thinking exerts a growing influence in areas including psychoanalysis, psychology, and human development. This book looks at the nature of Winnicott's thought and its influence. It first examines the development of Winnicott's thinking through his own life time (first generation) and then continues this exploration by viewing the thinking in members of the group with a strong likelihood of influence from him; his analysands (second generation) and their analysands (third generation).
