Besides constituting a fundamental milestone in contemporary Western thought, Sigmund Freud’s monumental corpus of work laid the theoretical-technical foundations on which psychoanalysts based the construction and development of the comprehensive edifice in which they abide today. <br><br>This edifice, so varied in tones, so heterogeneous, even contradictory at times, has stood strong because of these foundations. Indeed, this book shows, through its various chapters written by psychoanalysts from different parts of the world and sustaining varied paradigms, this enriching heterogeneity coupled with the invisible thread which strings together the diversity lent to it by the Freudian foundations.<br><br>One of the characteristics of the Freudian opus that is highlighted when studied in this perspective is its incessant improvement, where ideas and concepts are reformulated and become more complex as clinical facts and methodological and epistemological resources call for it.
