Does exploration of the gut microbiota–brain axis expand our understanding of what it means to be human? Recognition and conceptualization of a gut microbiota–brain axis challenges our study of the nervous system. Here, integrating gut microbiota–brain research into the metaorganism model is proposed. The metaorganism—an expanded, dynamic unit comprising the host and commensal organisms—asserts a radical blurring between man and microbe. The metaorganism nervous system interacts with the exterior world through microbial‐colored lenses. Ongoing studies have reported that gut microbes contribute (...) to brain function and pathologies, even shaping higher neurological functions. How will continued collaborative efforts (e.g., between neurobiology and microbiology), including partnerships with the arts (e.g., philosophy), contribute to the knowledge of microbe‐to‐mind interactions? While this is not a systemic review, this nascent field is briefly described, highlighting ongoing challenges and recommendations for emerging gut microbiota–brain research.

For most of the twentieth century, anthropologists understood themselves as ethnographers. The art of anthropology was the fieldwork-based description of faraway others—of how social structures secretly organized the living-together of a given society, of how a people had endowed the world surrounding them with cultural meaning. While the poetics and politics of anthropology have changed dramatically over the course of a century, the basic equation of anthropology with ethnography—as well as the definition of the human as a social and cultural (...) being—has remained so evident that the possibility of questioning it occurred to hardly anyone. In After Ethnos Tobias Rees endeavors to decouple anthropology from ethnography—and the human from society and culture—and explores the manifold possibilities of practicing a question-based rather than an answer-based anthropology that emanates from this decoupling. What emerges from Rees's provocations is a new understanding of anthropology as a philosophically and poetically inclined, fieldwork-based investigation of what it could mean to be human when the established concepts of the human on which anthropology has been built increasingly fail us.
