R. A. Lafferty’s doppelgängers tend to exemplify what Steven Swarbrick calls a “poetics of the incomplete” arising from the Lucretian-Lacanian gaps or minuses in matter, psyche, and language alike. Through accretion of nonhumans and dismemberment of humans, Lafferty’s ecopoetics of the unconscious is monstrous in both its excess and lack. This chapter explores the Laffertian ecomonstrous in three tales of doppelgängers: “Camels and Dromedaries, Clem” (1967), “Splinters” (1978), and “Cabrito” (1976). In each story Lafferty poeticises our failure to acknowledge the failure of ecosemiotics—that is, the failure to build our imagination around the fact that “life sings endlessly of its own incompletion and failure of full speech” (Swarbrick, The Environmental Unconscious: Ecological Poetics from Spenser to Milton, University of Minnesota Press, Minneapolis, 2023). Lafferty’s eco-perforated stories contain somewhat surprising moments of relevance, poignance, and even prescience to those living through pandemics and climate change in the 2020s. As Swarbrick argues, to overemphasise meaning in the world is yet another way to be anthropocentric. Lafferty’s ecopoetics of lack proffers alternatives to “the onto-clichés of ecocriticism” (Swarbrick, The Environmental Unconscious: Ecological Poetics from Spenser to Milton, University of Minnesota Press, Minneapolis, 2023): namely, the jouissance of more truly uncentring ourselves in the radically open-ended semiosis and asemiosis of planetary existence.
