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 (expressed through language) is only one possible medium of meaning. Adopting some concepts from Helmuth Plessner, I introduce another medium of meaning – corporealized meaning (expressed in physical terms), 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.
