Foam architecture: managing co-isolated associations

This article analyses Peter Sloterdijk's grand trilogy on spheres which re-conceptualizes our being-together and its spatial conditions. After a brief outline of the main objectives of sphereology, I analyse the notion of foam which, Sloterdijk argues, should replace the concept of society. I here explore the sociological theories that form the backdrop to Sloterdijk's idea of foam sociality, in particular Gabriel Tarde's monadological sociology of imitation but also the vitalist impulse that is central to the immunology of the foam theory, and which Sloterdijk inherits from Hermann Broch. The following section examines one of the important contributions of the foam theory, namely, its explicit engagement with architecture. In the final part, I offer a foam-theoretical interpretation of environmental crime prevention. This case study brings together foam theory, immunology and the focus on architecture.
