After decades of persistent claims for the development of interdisciplinary and integrated approaches to translation, Translation Studies now benefit from the contribution of various branches of learning that have brought about the multiplication of theoretical trends, viewpoints and research models within the field. Undoubtedly, the search for comprehensive perspectives and interdisciplinary alliances has led to major achievements in the discipline in recent times. However, it has also been the source of theoretical contradictions. This paper problematizes the concepts of interdisciplinarity and theoretical integration and explores some of the problems posed by the uncritical fusion of concepts, methods and viewpoints from different areas of study.
