In this episode, host Susan Mathews is in conversation with Kathryn Yusoff, Professor of Inhuman Geography at Queen Mary University of London. Her transdisciplinary research addresses the colonial afterlives of geology and race as a site of planetary transformation and social change. Her research is published in A Billion Black Anthropocenes or None (University of Minnesota Press, 2019) and Geologic Life: Inhuman intimacies and the Geophysics of Race (Duke University Press, 2024). The conversation centres around the science of geology and its epistemic and field practices. In her book Geologic Life, Yusoff notes that geology, which emerged in the late fifteenth through nineteenth centuries as a Eurocentric field of scientific inquiry, was a form of earth writing riven by systemic racism, complicit in the building of colonial worlds and the destruction of existing earths. The origin stories of earth and scripts of race are natal twins. Both mineralogical material and the subjugated person, such as on racial lines, were categorized as ‘inhuman’. She approaches this work not through a linear historical geography but through undergounds (as footnote, mine, appendix, subtending strata, and stolen suns) that reveal subterranean currents. Part of the task is to bring this whiteness down to earth through counter-gravities such as insurgent geology, non-fossil histories and questioning stratification. Broadly, Black, Brown, and Indigenous subjects whose location is the rift have an intimacy with the earth that is unknown to the structural position of whiteness. This inhuman intimacy represents another kind of geo-power: the tactics of the earthbound. So, whether it be through growing food, or making music such as the Blues, or the earth as a revolutionary compatriot, there have always been persistent resistances against these racialized relations. Yusoff speaks of the paradigm of the mine, which encapsulates this presumption of extraction. She speaks of how material value is stabilized in the present from skyscrapers to palm plantations, but both inhuman mineral “resources” and subjugated labouring people are relegated to the underground. The mine has also inspired carceral forms such as the prison complex. For a more reparative geophysics, we need to embrace practices that don’t start from the division between bios and geos and actually understand the earth and minerals as part of a kin relationship with a more expansive understanding of how the human comes into being. The separation between biology and geology is purely a kind of historical effect of disciplines and disciplining practices. These changes are even more important in the Anthropocene, where we have what she terms as a “white man’s overburden” with tech bros or predominantly White Western men deciding the future of Earth. Geobiology is a relational affair, and we need to see geology as a praxis of struggle and earth as iterative and archiving of those struggles.
