In the late nineteenth century, Jagadish Chandra Bose devised millimeter- and micro-wave experiments to record responses of plants to electromagnetic stimuli. Based on these experiments, Bose conceptualized his thesis of the unity of living and nonliving entities through their different sensitivities to electromagnetic vibrations. By relating Bose’s thesis of the unity of life based on electromagnetic vibrations to Alfred North Whitehead’s process philosophy and N. Katherine Hayles’s work on the cognitive nonconscious, I argue for a processual media theory that connects (...) both human and plant intelligence to electromagnetic signaling. In doing so, I examine how discourses about different living bodies (plants, animals, humans) variously sensing their environments are formulated into claims about which species have what degree of cognitive capability and intelligence. I trace the influence of Bose’s work on the ecological thinking of the 1970s espoused by cyberneticists and countercultural environmentalists and on contemporary plant neurobiologists who are closely working with Internet of Things designers and researchers. This enables me to emerge with an understanding of electrosensitivity that acknowledges that there is more to the intensities and energies of signals than mere data and that such infra-informatic signals can create both capacities and incapacities, capabilities and debilities, in bodies.
