Abstract

Hydrological landscapes played a significant role in the elaboration of Gaston Bachelard’s and Martin Heidegger’s historical epistemologies. More specifically, both philosophers relied on hydroelectric landscapes to explore nonlinear time and profound epistemological shifts in the history of knowledge. The landscapes they invoke are composed of hydroelectric dams, thunderstorms, and related landmarks like mountains, rivers, and lakes. Together, these varied yet connected elements offer rich environmental and conceptual terrains that I revisit to situate human knowledge formation within a much older natural history, and to lay the groundwork for a deep time theory of knowledge. Such theories promote timefulness and geological consciousness by establishing less anthropocentric historical narratives – or what Dipesh Chakrabarty calls “planetary history” – on more suitable epistemological grounds.
