Abstract: | The author examines the paradigm of the frontier and encounters the establishment of the paradigm of the network, a tendency that currently runs through diverse fields of thought. The network is not proposed as a globalising structure that would neutralise what is different, but as integration based on preservation of what is plural and its transformations. The author moves between these two paradigms in psychoanalytic metapsychology and clinical practice. The concept of frontier is intrinsic to the entire theory: repression, which separates the unconscious from the preconscious, the barrier against stimuli, the delimitation of spaces and agencies. But psychoanalysis is also a precursor of the paradigm of the network, with its concepts of unconscious, free association and evenly suspended attention. She points out that it is psychoanalysis that, in the area of scientific thought, subverts the radical split between subjects and their objects of observation, through the concepts of transference and countertransference, thus inaugurating a revolutionary theory of knowledge. This perspective can later be seen as a forerunner of changes in other disciplines. This text legitimises the contribution of psychoanalysis to thinking and knowledge, as well as the potential of a therapeutic method that provides the tools for crossing frontiers, unknotting and weaving networks, operating in the face of risks of pathological consolidations, thus holding to its unavoidable commitment to freedom. |
