ABSTRACT
Freud took the further significant step of freeing himself from the previous, more mechanistic concept that anxiety is a transformation of libido. When one first reads "Inhibitions, Symptoms and Anxiety", one notice that it seems to wander over various seemingly unrelated concepts and thoughts. It reviews of the second period in the development of psychoanalytic theory. The third period, from 1937 to the present, is concerned mainly with post-Freudian elaborations and the further ascendency of ego psychology topics that are covered in other courses. In obsessional neurosis, however, isolation operates in the service of the Pleasure Principle; that is, under the influence of an archaic ego, it wards off comprehension by keeping ideas and affects apart an illustration of a mental function acting as an asset to rational behavior, on the one hand, and as a neurotic defense, on the other. In addition, reaction formation involves doing the opposite in a single act, whereas doing and undoing are diphasic actions.
