Triplicity in Spencer-Brown, Lacan, and Poe

摘要: When speculative realists argue that objects should be considered apart from subjects, they frequently call on the support of George Spencer-Brown’s ‘calculus indications’; however, domesticate binary oppositions (e.g., day/night, good/bad, etc.) at expense radical antagonism identification indication with distinction, a ‘pre-Boolean’ alliance echoes Lacan’s own topologies ‘extimate’ (inside-out). Antagonism is not so easily dispelled. Speculative accept ‘thirdness’ Spencer-Brown and, later, Lacan employ strategically to address central questions about self-reference. I use evidence Poe’s ‘The Purloined Letter’ show how much Lacan’s, Freud’s, and ‘triplicities’ have offer project nonhuman.
