For at least two centuries most social thought has taken the earth to be the stable platform upon which dynamic social processes play out. Both climate change and the Anthropocene thesis – with their enfolding of dramatic geologic change into the space-time of social life – are now provoking social thinkers into closer engagement with earth science. After revisiting the decisive influence of the late 18th-century notion of geological formations on the idea of social formations, this introductory article turns to (...) more recent and more explicit attempts to open up the categories of social thought to a deeper understanding of earth processes. This includes attempts to consider how social and political agency is both constrained and made possible by the forces of the earth itself. It also involves efforts to think beyond existing dependencies of social worlds upon particular geological strata and to imagine alternative ‘geosocial’ futures. (shrink)

The Anthropocene has been observed as an opportunity to generate new legal imaginaries capable of revising incumbent assumptions of legal and political thought. What opportunities do such ambitions afford for communication between geological and legal thought? Responding to Birrell & Matthews attempt to ‘re-story a lawfor, rather thanof, the Anthropocene,’ I wish to describe some ways in which the Anthropocene Working Group, who are pursuing formalisation of the Anthropocene as an official geological unit, are involved in a similar exercise of (...) re-storying geology. The Anthropocene theme is brought to bear as a geological reality through material practices of measurement and correlation, as well as through the invocation of previous judgements of the evaluative committees associated with the formalisation of new geological unit. This effort amounts to a redefinition of the practices of geological observation, i.e. what counts as geologically relevant and why. In keeping with the theme of an ‘ethics of encounter’, as encouraged by Birrell and Matthews, this article suggests that the AWG’s effort provides a model with which the elaboration of ‘laws for the Anthropocene’ might correspond.

Whereas recent framings of planetary urbanization stress the planet-scaled impacts of contemporary urban processes, we might also conceive of cities as being constitutively ‘planetary’ from their very outset. This article looks at two ways in which the earliest urban centres or ‘civilizations’ on the floodplains of the Fertile Crescent harnessed the deep, geological forces of the Earth. The first is the tapping and channelling of sedimentary processes, central to what Wittfogel referred to as hydraulic civilizations (1963). The second is the (...) use of high-heat technologies to smelt and forge metals, which can be construed as a capture of igneous processes. What both sets of practices have in common is that they involve skilled intervention in fluid-solid phase transitions between solid rock and flowing particulate matter. Viewing cities as constitutively geological or planetary in this way can help us reimagine the challenges posed to urban spaces by looming transformations in Earth systems. (shrink)
