In this article, I argue that the symmetry and mutuality of any therapeutic relationship must be variable and reactive to the patient's unique needs, which will almost certainly change over time between sessions, but also even within sessions. Invoking the work of Jacques Lacan, I suggest that attempts to define a priori how a treatment necessarily should work and look are imaginary, in that they seek to establish a harmony and order to a project that cannot sustain either. As such, I offer that psychoanalysis as a discipline should be deconstructed in this important way: the dismissal of constancy related to either symmetry or mutuality. I put these ideas in contrast and complement to Levenson's work on the deconstruction of narrative truth. In addition to discussing Levenson, I also discuss the imaginary described in Lacan's early seminars, and review the existing literature on symmetry and mutuality. Afterward, I provide case examples that illustrate how I apply symmetry and mutuality in my own work with patients, and conclude by discussing how Lacan informs my work in psychotherapy.
