The object of this paper is the Elasticity of Psychoanalytic Technique in the work of Sándor Ferenczi. The author sustains that this can be considered neither as an ultimate arrival point nor as a particular stage of Ferenczi's clinical-theoretical body of work, but rather as an ensemble of affective qualities, attitudes and values, which he gradually developed through experience, signalling a paradigm shift in the history of psychoanalysis. The following areas will be explored: the new sensitivity demonstrated by Ferenczi concerning the relational and communicative factors present in the analytic session, his subtle and acute attention to the participation of the analyst's own subjectivity in the therapeutic process, and how these enduring elements of Ferenczi's technique anticipate several significant future developments in psychoanalysis.
