The present chapter is intended to review the broad context of eclectic psychotherapy and to consider the role of this Casebook within the integrationist Zeitgeist. First, I outline several definitions and manifestations of eclecticism with particular emphasis on systematic prescriptive eclecticism. Second, the growing need for an appreciation of casebooks are briefly discussed. Third, I comment on the organization of the book and the preparation of the cases. Finally, several “growing pains” of eclecticism are explicated and a developmental understanding recommended. 47 pp.
