Using the convergence between Bion and Matte-Blanco, in this article the author attempts to stress the view of the psychoanalytical method as promoter of expansion of the ability of the patient to think his emotional experiences. After a brief résumé of the ideas of both Bion and Matte-Blanco, certain points of congruence between the two are emphasised: the way of perceiving the range of phenomena observed by psychoanalysis, intuition as a method for observing this field, the feelings as the raw material for thinking, and the importance of the concept of infinity in psychoanalysis. The way in which the ideas of Matte-Blanco assist in the understanding of Bion's propositions is highlighted. Following these correlations, the author discusses certain questions pertinent to the psychoanalytical method and proposes a model in which the analyst acts as a mediator/catalyst in the process of revision of the ways in which the patient has organised his emotional experiences and the theories constructed to support these hypotheses. Samples of clinical material are presented
