The Author intends to highlight how the concept of enactment appeared for the first time at a psychodynamic level and then officially in an article by Jacobs in 1986. The term has been formalized by differentiating it from single-person concepts such as acting out and projective identification. Stressing the interactive nature of analytical dialogue, the concept of enactment forced analysts to rearrange the traditional reference theory and to look for shareable basic issues in representation made possible by the APA panel of 1992. The issue of self disclosure will become relevant after the theoretical and clinical changes derived by the recognition of the relational nature of analytical treatment. The question of enactment will also be discussed by the Author in the light of his personal representations, keeping in mind the difference between enactment and interaction, and the complexity and dialectic logic in which this dynamic takes place.
