Pluralism is the hallmark of 21st century psychoanalytic discourse. Nevertheless, an unpleasant byproduct of pluralism is a tendency in some quarters to retreat into orthodoxy, stemming from a perceived need to shore up theoretical boundaries in the service of differentiating one theory from another. The delineation of borders places us at a risk of losing sight of the fact that genuine psychoanalytic thinking is fundamentally non-reductionistic. Moreover, the core psychoanalytic notion of overdetermination, which Freud never abandoned throughout his career, has recently been neglected as authors argue in their communications that one point of view is better than another. Both analysts and their patients secretly are drawn to simple formulations that eschew complexity. The need to remain open to the ‘infinite space’ of meaning, motive, and causation should be a hallmark of clinical psychoanalytic practice. The author considers the implications for technique, and provides case material to illustrate some of the challenges inherent in approaching psychoanalytic work as a complex phenomenon.
