Afterimages and the Real: A Psychoanalytic reframing of Ontology

This essay examines the ontological status of afterimages by shifting away from the familiar physicalism-dualism debate and towards a more structural psychoanalytic reading rooted in Freud, Lacan and Klein. Building on Ito’s (2012) findings that afterimages originate in the visual cortex, I argue that these phenomena are not perceptual residues but hallucinatory stabilising structures emerging when the subject encounters the limit of representation, or “the Real” in Lacanian terms. Similarities with hypnagogic imagery collapse purely causal models, revealing ontology here as retroactive, not primary. Drawing from Lacan’s RSI (1974-75), Klein’s theory of splitting (1946), and Bataille’s sacred/profane distinction (1957), I propose that both physicalism and dualism operate as psychic defence formations against jouissance (or painful pleasure) rather than as philosophically neutral positions. Physicalism enacts the anal-retentive impulse to control (Freud 1908); dualism performs a libidinal misrecognition misrecognised as metaphysical longing. Neither of them touch the Real or what Bataille calls the sacred. Ultimately, afterimages are best understood as structural hallucinations that reveal the Real’s pressure on the imaginary order.
