Theories of a new phase of earth history, the Anthropocene, position human world-making activity as a bio-geological force. Social interventions into earth systems have been extensive and malignant, altering the earth’s surface, atmosphere, oceans, and systems of nutrient cycling. To adapt and respond to emerging planetary dangers requires the collaboration of scholars from many different disciplines. In this paper, I argue that a coalition of the arts and sciences might draw upon György Márkus’s extensive studies of the topography of ‘high’ (...) culture. I reconstruct Márkus’s conceptual map of the arts and sciences as regions of ‘high’ cultural activity, each with their own criteria of value yet subject to an integral unity and shared ambition. Both regions of ‘high’ culture aim to create original works of significance for an engaged public. I then examine the implications of Márkus’s claim that the classical vocation of robust, public-oriented culture has run aground. The field of problems that this paper traverses are not the ecological crises of the Anthropocene per se. I attend rather to Márkus’s account of the neoliberal erosion of cultural infrastructure where democratic publics might engage with such problems. (shrink)
