“…it was Levenson who first understood that continuous mutual unconscious influence necessarily implies mutual enactment. Do I seem to credit him too much? I don’t think so. In 1972, the original publication date of The Fallacy of Understanding, and for years thereafter, there was simply nothing else available on the subject. Jacobs (1991) actually was the person who introduced the word enactment into the psychoanalytic lexicon, at least as that word applies to the experience and conduct of the analyst. Jacobs offers marvelously sensitive accounts of the parts of his own life that his patients’ transferences stimulated him to remember and enact.”
