ABSTRACT
Borderline personality disorder is one of the disorders that have most contributed to triggering the crisis that has overcome all classical treatment models, from psychoanalysis to cognitivism. Ceccarelli summarizes the core concept of the relational theory of the mind as follows: the mind consists of the representation of the relationship between body and mind. In psychological and clinical work, the author believe it is indispensable to reflect on the need for and the choice of a theory which, in attempting to explain how the mind works, helps to identify the disorder, how it is expressed and how it can be treated. In psychology, some theories are hard to verify also on account of the historical split between mind and body, which in the Western world has often given rise to a pointless and harmful rift between organicists and non-organicists, medicine and psychology.
