In this chapter, we investigate the potentials and limitations of psychoanalytic epistemology when conceptualising creative disruptions to established systems of knowledge. Taking queer theorist Jack Halberstam as a privileged interlocutor, we offer a critical elaboration on the ways in which forgetfulness and stupidity may subvert routinised ways of knowing and being in the world. From a psychoanalytic perspective, we contend that the memory-work elicited in the analytic session is not aimed at completing knowledge about the past but at losing one’s mother (i.e. being able to forget), and that a sustained engagement with unconscious knowledge is not aimed at mastering truth but at staying stupid (experiencing truth as knowledge-in-failure). In a final reflection, we suggest that while the epistemic principles at the core of the psychoanalytic experience hold disruptive potential, they are limited tools that need to be supplemented with ethical, aesthetical, and political considerations.
