This dissertation is an ethnographic study of a small, interdisciplinary community of researchers working to field the controversial sciences of Plant Neurobiology, Cognition, and Behavior (PNCB). Building upon the analytical techniques of decolonial theory, feminist science studies and more-than-human anthropologies, my research situates PNCB not as a coherent epistemic aspiration but as an ongoing experimental dissensus: a creative rupturing in, rather than a re-distribution of, the scientifically sensible. By decentering the debates over who or what plants truly are, and whether or not they are “cognizant” or equipped with “neuronal-like capacities,” I focus on the practical, sensorial struggles of scientists risking their careers on the possibility that plants can think, learn, remember, and communicate with human and non-human others. The stories that emerge from this ethnographic attention document the uncertainties and the generative ethical and worldly potentials of scientists who no longer know from where the source of their knowing stems. These are stories of scientists actively struggling to think creatively about plants, to dishabituate from their prior trainings and familiar categories of thought, agency and sensation. My research suggests that it is within these experiences of “not-knowing”—mired in feelings of uncertainty, surprise, agitation, etc. —that it becomes possible to feel the many strange and unexpected plant configurations that embolden a re-imagination of a scientist’s “knowing.” Immanent to these encounters are phenomena I am calling “phyto-innervations,” in which my capacity to know and make sense as an ethnographer is also made susceptible to creative, more-than-human constellations.
