Today, the environment is in us, and we humans are fully in the environment. That much is clear in this new planetary era of uncertainty some call the Anthropocene. Postdisciplinary practices and situated knowledges (Haraway again!) are of course especially salient in this regard: a brute necessity. The planet knows no disciplinary borders, it does not separate between nature and culture. Our planetary issues can not be solved by demarcations where sciences do nature and humanities do culture. In truth, our Anthropocene predicament belies the whole classical distinction between nature and culture! The needed efficacy of such postdisciplinary work is evidenced in many new, old and déja vu fields like feminist science studies and networked new materialisms, in bio-art and eco-art, in somatechnics, new media studies, post-continental philosophy, in anthropocene studies or transcorporeal theory, in multispecies- and medical humanities, in transgender studies, xenofeminism, cyborg- or techno-humanities, ecological or environmental humanities, queer death studies, critical veganism, and a mounting range of posthumanisms, inhumanisms and ahumanisms. Yes, critical and creative scholars in and around the humanities have not been lazy in the face of the many issues that face us today. Feminist posthumanities cover or converse with such postdisciplinary practices. It labels a wide-spread, multi-sited, evolving and growing effort to rework the role of the humanities and their relation to science, technology, art and contemporary society on the basis that our idea of the human is fundamentally reaching its limits, and changing. Feminist posthumanities thus responds to the need for more-than-human humanities.
