This started out dense and assumed a knowledge of analytic theory that far outspans my limited understanding of some of Bollas's reference points. However, I forged through because of his distinct voice, and his devotion to following the idea of psychoanalysis to the furthest point, with equal parts exploratory rigor and deep compassion. The gravitational point around which chapters of varied topics hinge is the unthought known -- an essence which is the environment or mood in which each person situates themselves, identifies themselves by in some instances, creates for the other, and in Bollas's opinion is created by very early (sometimes infant) childhood experiences. I am someone who is three years into being an analysand, and I still struggle at times with the idea that the psychoanalytic project is all some sort of complicated quackery if not an egotistical indulgence, but books like this remind me analysis has promise for unresolved personality structures of all kinds, sick or healthy, and reading about types of analysis (because this book really was written more for clinicians than laypersons) reminds me of how varied but universal the human experience is. P.S. I love Christopher Bollas's VOICE. His vernacular is sometimes hilarious. I will be reading more of him.
