This text retakes the question of the therapeutic nature of psychoanalysis to take into account the new Paradigm of Complexity and the question of the self-organization of living beings. In the 40s / 50s of the twentieth century, radical change in science occurs with the emergence of cybernetics that leads to a profound reconfiguration in approaching reality with ideas of system, self-organization, indeterminacy and non-linearity. From these facts we can recognize the emergence of a new epistemology, a complex epistemology insofar that do not approach reality in a reductionist way, septate, but in such a way that all dimensions of reality are seen as configuring a system “living being - environment”. So what has changed in psychoanalysis with the paradigm shift? Thinking about a new vertex does not change what is observed, but its understanding. Psychoanalysis continues to be Psychoanalysis and continues depending on this personal relationship that occurs in the setting. The arguments brought being little discussed in our midst, A. extends the description of the work that demonstrate new approaches to reality of the new terms to describe them which have recently been incorporated into the scientific vocabulary.
