On Saturday 16 June 2012, 14.00–16.30, the Tate Modern will host a conversation between German philosopher Peter Sloterdijk and British geographer Nigel Thrift. For a while I’ve harboured a curiosity – still largely uninformed – about Sloterdijk’s ‘sphereology’ which is encapsulated by his three-volume magnum opus Spheres (taking in bubbles, globes and foam). I think, in part, it is because of my obsession with the idea of the public sphere (or maybe it’s public spheres), yet dissatisfaction with the way it is often theorized. I’m not taking a stab at normative political theory here, however, as actually I think a processual view of publics is critically important and even preeminent. But I suppose there is a side to me that is interested in what Paolo Carpignano called the material shape of the public sphere. Anyway, I didn’t mean to make this post a detailed exploration of spheres, mainly just to point to the event itself (for which there is a £15 ticket it seems), found via the ANTHEM blog via Stuart Elden.
