Already in the nineteenth century, German-language writers were contending with the challenge of imagining and accounting for a planet whose volatility bore little resemblance to the images of the Earth then in circulation. The Geological Unconscious traces the withdrawal of the lithosphere as a reliable setting, unobtrusive backdrop, and stable point of reference for literature written well before the current climate breakdown.

Through a series of careful readings of romantic, realist, and modernist works by Tieck, Goethe, Stifter, Benjamin, and Brecht, Groves elaborates a geological unconscious-unthought and sometimes actively repressed geological knowledge-in European literature and environmental thought. This inhuman horizon of reading and interpretation offers a new literary history of the Anthropocene in a period before it was named.

In those depictions of human-mineral encounters, the minerality of the human and the minerality of the imagination become apparent. In registering libidinal investments in the lithosphere that extend beyond Carboniferous deposits and beyond any carbon imaginary, The Geological Unconscious points toward alternative relations with, and less destructive mobilizations of, the geologic.
