I have recently been involved in debates with posthumanists about how to challenge the economic, political, and ecological absurdities of our contemporary world. It is easy for most of us to agree that the current trajectory of global society is a source of frustration, to say the least, and I don’t think I need to refer to statistics on rising inequality or the transgression of “planetary boundaries” to amplify that feeling. A significant number of anthropologists and other social scientists today seem to want to turn their backs on modernity. For many anthropologists, this is an ontological turn. It means identifying with the nonmodern worldviews of the people who have hosted them during fieldwork. Some problems with this approach are discussed in Chapters 10, 11, and 12 of this book.
