This book is interesting but can not be understood without knowing the work of Lacan, Freud on religion (rf the future of an illusion) and Dolto.C'est a book is written in a simple and s 'a priori open to all players (working or not in the middle of psychology) It's amazing because at Beyond its "all age", this book refers to very complex concepts and the entire theory and Dolto Lacan on catharsis, the relation of the subject to his own word and Lacanian notion of speaking being and object a.C'est must read a book and that leads to reflection.
