The author surveys Bion's publications and elaborates on his key contributions in depth while also critiquing them. The scope of this work is to synopsize, synthesize, and extend Bion's works in a reader-friendly manner. The book presents his legacy - his most important ideas for psychoanalysis. These ideas need to be known by the mental health profession at large. This work highlights and defines the broader and deeper implications of his works.It presents his ideas faithfully and also uses his ideas as "launching pads" for the author's conjectures about where his ideas point. This includes such ideas as "the Language of Achievement", "reverie," "truth," "O," and "transformations"- in, of, and from it, but also " L," "H," and "K" linkages (to show how Bion rerouted Freud's instinctual drives to emotions), "container/contained, Bion's ideas on "dreaming," "becoming," "thoughts without a thinker," "the Grid," his erasure of the distinction between Freud's, "primary and secondary processes " and the "pleasure" and "reality principles," "reversible perspective," "shifting vertices," "binocular vision," "contact-barrier," the replacement of "consciousness" and "unconsciousness" with infinity and finiteness, Bion's use of models, his distinction between "mentalization" and "thinking," as well as many other items.
