The idea of an Anthropocene has spread with astonishing speed, dislodging familiar terms like nature and environment from their customary preeminence as signs of the world beyond ourselves. These developments pose a peculiar challenge for those of us in anthropology. To be sure, everyone suddenly seems to share our concern for that singular creature, anthropos. Yet, the Anthropocene is a gift armed with teeth, with a hau of demands and reciprocal tethers that have left many anthropologists rightly cautious about embracing its tale of an overwhelming human agency. What would it take, we wonder, to see this time and its configurations, agencies, and effects otherwise? With this lexicon we hope to develop a resource that is helpful for this task.
