It was originally suggested that the Anthropocene began in 1784, the date of James Watt’s patent for the rotative steam engine. Patent dates are interesting artefacts. They owe their existence to the chronopoietic technique of patent jurisprudence, which generates temporal sequences out of synchronous states of knowledge. This may not be geological time, but it informs the experience of time that is proper to the culture whose deposits of Pu-239 now mark the onset of the Anthropocene. Patent jurisprudence makes a (...) crucial contribution to what might be called the ethos of the Anthropocene: the sense of society as having an inexhaustible capacity for innovation, for endless self-renewal. And, as it turns out, the steam engine yields some interesting insights into this mode of enchantment. (shrink)

If the twentieth century was the age of the world picture taken as a photograph of the Whole Earth from outer space, today’s observations of the planet are produced by means of computer simulation. Pandemic models are of paramount sociological interest in this respect, since modelling contagion is closely intertwined with modelling the material connectivities of social life. By envisioning the global dynamics of disease transmission, pandemic simulations enact the relationscapes of a transnational world. This article seeks to analyse such (...) an enactment: It asks how simulation methods can establish a particular relation to the social from within the social. To provide an answer to this question, and adopting Niklas Luhmann’s theory of world society, pandemic simulations are described as modes of global self-observation that can be specified factually, socially, spatially and temporally. They instantiate a ‘doubling of reality’ designed to apprehend the potential future threat of disease transmission along the pathways marked by global infrastructures. They constitute scopic regimes that virtually synthesize a global situation of universal communicability in order to turn the world into an object of political intervention. (shrink)

Technology has developed to the point where a clear distinction between nature and culture seems to be dissolving. Against this background, a broad aspect of social research has emerged that considers an interdependence between the social and the material. So far, social-systems cybernetics as described by Luhmann has remained rather marginalized in these discussions. This article is intended to overcome this marginalization by developing the concept of meaning. Meaning can abstractly be defined as a ‘doing negativity’. Returning to systems theory, (...) it becomes obvious that verbalized meaning is only one possible medium of meaning. Adopting some concepts from Helmuth Plessner, I introduce another medium of meaning – corporealized meaning, which also operates meaningfully along the distinction between actuality and potentiality, and thus does negativity. I discuss consequences of observing the relationship between sociality and materiality from this perspective. (shrink)
