The paper by Elizabeth Allison & Peter Fonagy (2016) "hen is truth relevant?"(translated in issue no. 1/2020 of Psicoterapia e Scienze Umane) is discussed from the viewpoint of cognitive therapy, in particular of the recent cognitivist perspective influenced by the contributions of the Italian researchers Vittorio Guidano and Giovanni Liotti and by attachment theory. This new perspective within cognitive therapy includes a constructivist approach to knowledge and values the intersubjective dimension of mental processes, with an emphasis to the role of the therapeutic relationship in the treatment strategies. The theoretical and clinical aspects of a dialogue between the cognitivist and the psychodynamic approaches are discussed, in particular regarding the concepts of "truth" and "epistemic trust"; cognitivist and the psychodynamic approaches have specific differences, but old oppositions could be overcome and these two approaches can come closer to each other.
