“…Here, a series of five interventions from geographers, historians, and political scientists respond to a new English-language translation of Ratzel’s essay and, in so doing, seek both to contextualise the development of Ratzel’s thought, and to advertise the relevance of his essay to ‘ongoing debates in geography and beyond’ (Klinke and Bassin, 2018: 58) around issues of biopolitics, colonialism, geopolitics, and nature-society relations. In their introduction to the special section, Klinke and Bassin (2018: 54) argue for the value of reframing our understanding of Ratzel’s essay – to see it, and him, as foregrounding modern biopolitics and as embodying ‘a “more-than-human geography” that tries to bridge the divide between science and philosophy’ (see also Barua, 2018; Chiantera-Stutte, 2018). While repositioning Ratzel as a more-than-human geographer is clearly terminologically anachronistic, it is arguably not an entirely presentist imposition; Ratzel’s work, much like that of Alexander von Humboldt, was infused with, and predicated upon, monism – a belief in the fundamental unity of life and earth (Rupke, 2012).…”
