This chapter constitutes a preliminary exercise in investigating the productive consequences for psychoanalysis of a Žižekian reading of Lacan. By providing a new periodization of Lacan’s teaching—one which renders legible an insisting and unresolved impasse in psychoanalytic thinking, tying together its clinical, conceptual and institutional dimensions—it demonstrates how the Žižekian theoretical space is capable of thinking continuous and immanent transformations between philosophy, psychoanalysis and politics. In its periodization of Lacan’s teaching, this perspective renders legible a philosophically instigating emergence of certain intrinsically political concerns at the heart of psychoanalytic thinking itself.
