In this work the author, through a brief historical-theoretical excursus, aims to fill a conceptual void on the phenomenon of Mentalizing, trying to understand with which vicissitudes of thought the sympathy of humeana memory has come to thecontemporary to "make people talk about themselves", firstly as a Folk Psychology and then as "mind reading". With this awareness, therefore, this volume fits into the conceptual tradition of directing the reader or simple onlookers in their research on the subject.
