This paper explores sources of therapeutic action located in inchoate experience, in the often-preconscious resonance that is generated in that dimension of experience which we have come to regard as enacted in the transference/countertransference field. The living and working through of a wide range of problematic and reparative elements distilled in the analytic relationship are described as a crucial source of therapeutic action. A brief historical treatment of the place of enactment in different psychoanalytic traditions is followed by the explication of two different kinds of enactments: ordinary, quotidian enactments that form the daily ebb and flow or ordinary analytic process and (capital E) Enactments. The latter are highly condensed precipitates of unconscious psychic elements in patient and in analyst that mobilize our full, heightened attention and define, and take hold of, analytic activity for periods of time. Clinical vignettes by Theodore Jacobs and Margaret Black are discussed in explicating the latter distinction and considering its implications for technique.
