Your co-hosts wonder why coal seems so sinister and they’re pretty sure it has something to do with all those Santa-related threats. Then (8:51) we welcome University of Chicago environmental and intellectual historian Fredrik Albritton Jonsson to the podcast to discuss his two remarkable books, Enlightenment’s Frontier: The Scottish Highlands and the Origins of Environmentalism (Yale, 2013) and Green Victorians: The Simple Life in John Ruskin’s Lake District (co-authored with Vicky Albritton; U Chicago, 2016). Fredrik takes us back to mid 18th century Scotland and 19th century England to discuss the deep historical roots of contemporary concerns about fuel, growth and the natural limits of growth. We talk about competing energy and environmental visions in 18th and 19th century political economy and natural history. We touch on 18th century climatology, the nuances of Adam Smith’s value theory and how British imperialism contributed to undermining the importance of land and population in economic theory. We debate whether physiocratism is on the rise again and Fredrik let us eavesdrop on his conversations with Dipesh Chakrabarty about how to think about the Anthropocene. Finally (51:10) we turn to art historian and renegade political economist John Ruskin, whose concerns about anthropogenic climate change in the 1860s and 1870s led him to form an early “post-carbon” community in Britain’s Lake District. Yet, surprise surprise, his “simple life” turns out not to have been that simple after all :) Are fossil fuels really the edifice of modern notions of equality and freedom? Listen on!
