In the new planetary age of the Anthropocene or the Age of Man (as it were), humanity is cast as a single geological force, a major force of environmental destruction, and one folding in on itself. The Anthropocene is famously defined by human-induced climatic, biological, and geological transformations of our planet, by a profound anthropogenic environmental impact and mass species extinctions. However, the Anthropocene risk also, as pointed out by a wide range of feminist philosophers and critical scholars, to hide troublesome differences between humans, and also to hide intimate relationships between technology, humans, and other animals. This totalization of humanity is a parallel risk in some posthuman theorizing also, and something postdisciplinary scholars of the critical humanities and feminist philosophers have paid attention to for decades. In the posthuman context of the Anthropocene, I suggest and point to postdisciplinary humanities research and theory–practices that pay careful attention to the feminist theoretical work on our equally postnatural condition as an experimental remedy.
