The Duino Elegies is a collection of ten elegiac poems written by Austrian-Bohemian poet Rainer Maria Rilke (1875-1926). At turns mournful and ecstatic, sardonic and visionary, the Elegies were composed from 1912-1922, a period marked by the so-called “language crisis” (Sprachkrise) in German-speaking modernist circles and the entirety of the First World War. The poems’ major themes include this crisis, the role of divinity in a secularizing society, and the ways in which the mass production of commodities threatens human relationships with things and with other humans. The latter point will be the focus of my presentation. Drawing on scholar Teresa Brennan’s interdisciplinary studies of the energetic, psychic, social, and economic aspects of modernity, I read the Elegies as presenting a theory of energy that is at once an affective, poetic experience of modernity in Western Europe. More specifically, I show how the Elegies map out and respond to a collective psychic exhaustion. Alongside Brennan, I argue that capitalist production in modernity—and the attendant accelerations in transportation and communication—is the main culprit. Collective psychic exhaustion finds its correlate in natural exhaustion—the depletion of natural resources extracted for commodity production—which, if not yet catastrophic in Rilke’s time, certainly is now. It should be noted that Rilke is a western, middle-class poet, and his work can by no means be read as speaking for all of ‘humanity.’ Yet with capitalism having only become more global, pervasive, and hegemonic since Rilke’s time, the Elegies offer illuminating insight into our own heterogeneous, global experiences—social, psychic, and energetic—of capitalism as it unevenly and differentially entangles, exploits, and mangles various parts of the world.
