Lightning on the Upper Reaches of the Lethe opened across modern history on Jan. 12, tracing unsettling synchronisms between nineteenth-century colonial surveys and digital modeling, E-Flux reported.
The exhibition examines whether an irrational history of technology exists beneath rectilinear surfaces. Colonial triangulation, polygonal meshes, and artificial intelligence datasets all translate the heterogeneous sea of lived phenomena into a lucid, linear cognitive universe. Yet the meandering river of Lethe continually returns, folding fear and memory back into the landscape, according to E-Flux.
Mark Hansen proposed the notion of a worldly sensibility, directing attention to the conditions under which experience takes shape before consciousness arrives. Cao Shu’s practice is attuned to these opaque moments of feed-forward, where the non-human mysticism of climate and geology remains at work.
“Time is paradoxical; it folds or twists; it is as various as the dance of flames in a brazier—here interrupted, there vertical, mobile, and unexpected,” Michel Serres and Bruno Latour wrote in Conversations on Science, Culture, and Time.
Colonial Surveys Mirror Digital Modeling and Artificial Intelligence Datasets
Nineteenth-century colonial surveys attempted to prove that two differently named rivers shared a single origin. This cartographic drive mirrors contemporary polygonal meshes in digital modeling and datasets used for training artificial intelligence. Jon Auring Grimm examined ecological and planetary thinking in Georges Bataille in the Journal for Cultural Research.
The Flash of History
Within the showcase, one finds a haunting correspondence linking the light that vaporized human forms in Nagasaki to the camera flash that permanently records a subject on photographic stock. Such moments intersect with sci-fi cinema storylines driven by missing main characters and visuals sourced from the brain tissue of dead rodents, guided forward by unseen recollections.
Eugene Thacker explored the horror of philosophy and the non-human mysticism of climate and geology in the Dust of This Planet. Hansen argued that bodily processes and environmental forces unfold beneath the threshold of consciousness.
Permeable Historical Perception
Lightning on the Upper Reaches proposes a permeable mode of historical perception that gently unsettles the linear narrative of progress. This narrative is constructed primarily through invention, institutions, and media.
Each flash of lightning briefly illuminates the darkness before the world falls back into shadow. Yet the lightning returns, again and again, upstream of Lethe.
The project continues to examine how technical operations feed forward into perception and action before conscious interpretation takes hold.
