This is a very important book for psychoanalysts, one that is well worth the effort of reading, although it will prove challenging and at times difficult for English-language readers in general, and perhaps for some American readers in particular. The central challenge is one that we continually face with most, if not all, our patients, and have faced since Freud: how to find words with which to describe the ineffable, the ineluctable, the not yet articulated or even pictorially represented; the unconscious as impulse, movement, potential before it is limited in possible meaning and “tamed” by being joined to words: the very substrate of raw, un-processed—and unprocessable—experience that will come to constitute an important part of the unconscious and from which consciousness and the agencies that make up the mental apparatus will emerge.
