In this note I walk away for a moment, of the issues linked to our forensic practice to transcribe an interview in which Jacques-Alain Miller exposes with great clarity the position of psychoanalysis against cognitivism. In our activity within the area of forensic psychology permanently use psychometric techniques and projective on the basis of the conclusions of our opinion. But those who adhere to the psychoanalytic theory can not stay only in the analysis of semiology, the results of the techniques of psychodiagnosis, or an enumeration of symptoms, but listen to a subject. Listen to this subject means that we do not forget theory, because although psychoanalysis was not interested in the diagnosis of the neurotic, psychotic or perverse that we can cross us on the street, but you are interested in the diagnosis that builds on transfer, or you are interested in the diagnosis of symptoms but the diagnosis of structure; and even though for psychoanalysis we aren’t Cartesian subjects installed before the world as a simple scenario in which everything is an object for which you are looking, this does not mean that we forget of psychoanalytic theory and metapsychology to know something more about the psychological reality of the examinee. How to explain the trauma? How to explain the determination of its clinical manifestations without taking into account the concept of repetition? How to explain the determination of a symptom of psychogenic etiology without considering the concept of unconscious? Do we explain that sometimes the answer to a reagent of the MMPI-2 is a depends on does not exist? Do we explain there is apperception in techniques such as the Rorschach? The possible questions are endless. Psychoanalysis is the only theory capable of shedding light on the determinants that someone is neurotic, psychotic or perverse, going beyond the phenomenology and the pure description. Then the interview published in the site of the World Association of psychoanalysis.
