John Ruskin and Karl Marx – two heterodox economic thinkers writing in England in the 1860s – both considered production, circulation, and exchange in relation to the natural environment. After first discussing the imbrication of the economic and the ecological in their work, this chapter turns to George Eliot’s Felix Holt [GK19](1866) and Anthony Trollope’s Orley Farm [GK20](1861–62) to explore points of intersection between heterodox economic thought and literary realism. Focusing on soil fertility, an issue that evokes the uses of water, soil, and manure in service of capitalism, the chapter shows that Eliot and Trollope trace the ways in which ownership, labor, or trade transforms humans’ relations to animals, plants, and landscapes. Heterodox economic thought and literary realism in the 1860s took into account historical dimensions of the natural world, especially its economic involvement.
