This book is practically unreadable, and whoever touted this book as being introductory or for the general reading public didn't know what they were talking about. The first chapter is difficult primarily because of the author's seeming inability to appreciate that what's clear to him isn't necessarily clear to the reader i.e. he writes of 'error suppression' as part of top down process but doesn't make clear what this could mean, does it mean suppressing the error or does it mean suppressing error making activity or what ?, I don't know and having read the book still don't know. The other chapters are supposed to be somewhat easier though they too are full of half explanations. The author in my opinion may be well published but going by this book this can't be because of his ability to explain his ideas.
In all my forty odd years of reading in the area of psychoanalysis/psychiatry I have rarely come across work as really awful as this confusion of levels of explanatory abstraction. It's hard to believe that an established psychiatrist/psychotherapist could write something like this and that any publisher worth their name would publish it. My summary of this book is intellectual vomit, a hodgepodge of ideas from different levels of abstraction stuck together resulting in meaningless waffle.
Freud attempted to explain psychological concepts in his early 'Project For a Scientific Psychology' but gave up partly because he regarded neurology as not being sufficiently developed in order to do so. He was however able to develop a 'metapsychology' a psychology to provide an explanatory framework for his clinical concepts and unlike this author he made sure that he didn't confuse these levels of explanation. To do so would have been to produce the sort of mess that this author has produced with this book.
