This book connects recent developments in speculative realism, new materialism, and eco-phenomenology to articulate an approach to wonder that escapes the connected traps of anthropocentrism and correlationism. Brian Onishi argues that wonder has explanatory power for the constitution of the world and the organization of meaning. To do this, he appeals to both fiction (speculative and Weird fiction in particular) and quantum physics. More specifically, he argues that the focus of Weird fiction on impossible experiences and a feeling of something just beyond the limits of one’s grasp dramatizes the speculative reach beyond the limits of our understanding. But more than a tool for knowledge acquisition, wonder is an organizing property of objects. Like the collapse of superposition in quantum physics, reality is constituted when objects reveal themselves to other objects and thereby organize themselves into complex objects. Since no relation is exhaustive, the capacity to wonder remains at a material level, and the possibility of reorganization is ever present. Ultimately, Onishi argues for a speculative eco-phenomenology with wonder as an engine for a Weird environmental ethics.
