This chapter addresses the experimental potential of the eco-weird, offering a refreshing angle from which to study the intersection between weird fiction and environmental thought. In contrast to traditional weird fiction, contemporary weird texts increasingly engage with the environmental crisis via techniques such as humor and self-reflexivity, targeting the reader’s positionality and ethics vis-à-vis the text and, by extension, vis-à-vis the sociopolitical and ecological context. As a way of situating this potential within the broader ecocritical conversation, I take my cue from literary scholar Nicole Seymour (Bad Environmentalism: Irony and Irreverence in the Ecological Age. University of Minnesota Press, 2018), who proposes a less instrumentalist approach to environmental art, opening up the (according to Seymour) self-limiting sanctimoniousness of ecocriticism in productive ways. Similarly, in this chapter I discuss weird texts, such as Reza Negarestani’s Cyclonopedia: Complicity with Anonymous Materials (2008) and Jeff VanderMeer’s Borne (2017), that use explicitly experimental narrative techniques to challenge traditional weird poetics on the one hand and environmental thought on the other. Seymour asks what it means when a work employs the “wrong” (i.e., nonnormative) tone or adopts the “wrong” (i.e., nonnormative) disposition toward the environment. This chapter is, in part, a proposition that the weird is well-equipped for this kind of “bad” environmentalism.
