he corrects Freud when wrong---as in his critique of the Death Instinct---yet he presents, extends, and applies Freud's science in a comprehensiveness and accuracy which no other psychoanalyst has since done. Fenichel not only summarizes and clearly explains theory, but also provides case-histories. He also decribes the most basic concepts of psychoanalysis such that any intelligent layman/woman could use this book as a starting point, though the book does reach a very sophiscated level after the introduction and early chapters. Very significant is Fenichel's presentation of how mere neuroses can advance to psychoses, and that solely mentalistic causes can force such an advance; this etiology ruptures the current fashion ofthanx,
emphasizing brain-biochemical causes, or, holding biochemicals to be the ONLY cause of mental illness; Fenichel's work here shows why the biochemical/physicalist-theory is at best half-true (despite the best marketing tactics of American pharmaceutical companies, and the outright bombast of the psychiatric community).
