ABSTRACT
Depending on their organizing principle, the models, metaphors, and theories shape the unconscious with different dimensions, properties, and consequential clinical compasses. It could be considered that the unchangeable nucleus of the hypotheses on which psychoanalysis is based is constituted by the basic notion developed by Sigmund Freud on the central role of unconscious activity in human mental functioning. Understanding the dimensions of the models of unconscious, and the consequent different theory of psychic change they incite with their technique, leads to modifications in the frontiers of analysability. The widely discussed "isolation" of psychoanalysis refers not to the use of general knowledge in psychoanalytic models, but to the difficulty of psychoanalysis to be integrated and understood by other disciplines. Knowing the models in depth, its origins and articulation with non-psychoanalytic elements, could certainly help in this difficult task.
