Rik Loose's seven entries for the Edinburgh Encyclopaedia of psychoanalysis are on: addiction, aggressivity, lamella, mimicry, need, push-to-the-woman and toxin. The Encyclopaedia provides a wide, objective and catholic vision of psychoanalysis, demonstrating that it is a single discipline, very much greater than any particular movement, school or individual, including its founder, Freud. Thus the book contains authoritative entries on all the most important authors, practitioners, concepts, movements, schools, debates and controversies in psychoanalysis and its offspring, past and present. A precis essay is given of each school amplified by explanations of all key terms within that school. Entries are alphabetically arranged.
