Mentalizing and Epistemic Trust offers a critical overview of MBT, exploring its roots in attachment theory, and more broadly. The main theories and concepts in the work of Fonagy and colleagues are placed in an historical and social context, and changes occurring in the present moment are thoroughly appraised. The authors convey an impression of the extremely significant and far-reaching influence of the ideas behind mentalization and the relevance of these. This book is likely to appeal to those interested in the considered and nuanced detail of the evolution and modifications of these ideas.
