Intellectually as well as materially, the Anthropocene is a deeply cultural phenomenon. This includes its communicative form, which is a contested trope-rich narrative, even within the sciences. In this essay I focus on the role of metaphor in Anthropocene thought and in particular, on the provocative, ambiguous, and potentially far-reaching idea of humans as a geological force. By considering the different interpretations and meaning this metaphor encourages - including differences in what is meant by geological and force, both within and beyond stratigraphy and Earth System Science - we gain a stronger sense of the deeply allegorical and theological character of the Anthropocene story and the way it promises to reposition humans in the world.
