Colloidal Social Theory: Thinking about Material Animacy and Sociality beyond Solids and Fluids

Abstract

This paper argues that an exploration of colloids can help us situate human social life within a wider understanding of the sociality and animacy of matter. Colloids are substances such as sols, foams, powders, gels, doughs and pastes that exhibit complex and shifting macroscale physical properties that do not conform to standard conceptions of solids, liquids or gases. Colloids can behave in complex and creative ways because of their topological enfolding of dispersed and continuous matter, in different phases, at a ‘mesoscale’ intermediate between the scale of molecules and that of the macroscale substance. I relate colloids, with their twin phenomena of ‘repetition’ and ‘mediation’, to an understanding of social life as reducible neither to the interaction between separate individuals nor to a transindividual whole. I suggest that human social life participates in a colloidal ‘metapattern’ of repetition and mediation that is manifest across diverse material substrates and spatial scales.

Paradigm shifts for a planetary emergency: Towards an anthropocenography for urban coastal research at False Bay, Cape Town, South Africa

“…First, transport and residential infrastructure that are characterised by hard-surfacing using anthropogenic rocks such as concrete and tar that specifically introduce impermeability into geological landscapes, changing biogeochemical processes at the interfaces of solids and liquids (colloids 45 ) and airborne particles (dust, mist and smoke). These geological changes of the Bay are occurring in the present.…”

The politics of subterranean atmospheres in China: a study of contemporary chinese mining art

“…Steinberg and Peters (2015, p. 255), whose well-cited work focuses on oceanic water, argue for less of a geological and more of a geophysical approach that "configures a world that is open, porous, mobile, and changing, but concurrently one that can stabilise temporarily." Indeed, elemental experimentalists and thinkers have argued similarly for greater porosity and entanglement between materiality and body (Adey 2016; Nieuwenhuis & Nassar, 2018;Engelmann and McCormack 2011;Szerszynski 2021). Engelmann (2020, p. 3, original emphasis) reminds her readers that "to be affected by air, to be a breather, is to be in common with other breathing bodies and to register a medium that ties the body to the city, the region and the planet."…”
