Cerebral Protuberances. Towards a History of Intellectual Work. In this paper, I unfold the implications of Warburg's notion of “cerebral protuberance” (German: “Gehirnhirnausstülpung”) for a historical epistemology of intellectual work and material imagination. Attention to the penultimate character of conceptual language, I argue, allows for an analysis of unconscious aspects in the process of knowledge formation. Revisiting Gaston Bachelard's conception of historical epistemology in the age of neuroplasticity, I suggest to attend to the reverberations between history of science and intellectual (...) history in order to arrive at a better understanding of the exteriority of intellectual activity and the importance of affect in scientific and scholarly production.
