This article argues that social networks constitute an inauthentic form of sociality. The two component concepts of this claim, inauthenticity and sociality, are explored in order to avoid some widespread misinterpretations. Inauthenticity is examined on the basis of the relevant sections in Heidegger’s 'Being and Time', first with respect to its main characteristics, then in terms of what motivates it and its benefits, and finally with respect to its status as a non-normative concept. The second part of the paper explores (...) sociality. Here, a main emphasis is the way in which my body imposes constraints on my social relations in the here and now, which virtuality appears to overcome. Yet such an escape from corporeality is not ultimately possible. The third and final part takes the analysis to the wider level of world, that is, our current historical world which has given rise to such an understanding of sociality. (shrink)
