Mishima and the Existence of Thanatos

The Freudian death drive (Thanatos) has been scientifically refuted and is heuristicallyreplaceable, yet it persists as an ineradicable reference in aesthetics, philosophy, and culturaltheory. This paper proposes that the concept’s survival is attributable neither to clinical utility nor tophilosophical productivity but to a singular historical event: Mishima Yukio’s seppuku of November25, 1970. Drawing on Austin’s speech-act theory, Butler’s performativity, Hacking’s loopingeffects, and Nishida Kitarō’s acting intuition (kōi-teki chokkan), the paper introduces theexploratory concept of performative epistemological status change: the transformation of aconcept’s epistemic standing through a performed act that enacts its content. The Socratic precedent,the Crucifixion, and Thích Quảng Đức’s self-immolation suggest that this mechanism recurs acrossconceptual history. The result, in Mishima’s case, is an “undead concept” — theoretically dead butfactually alive — whose mode of existence reflexively instantiates the very life/death fusion itdescribes.
