This special issue examines Luhmann's concept of meaning as a central medium for both psychic and social systems, structured across three canonical dimensions: factual, temporal, and social. The call argues that while these three dimensions are foundational to systems theory, the underlying logic of why meaning should be organized into exactly these three dimensions remains unresolved. Recent scholarship suggests that meaning may be better understood as a potentially expandable framework responding to basic questions of observation, with additional dimensions such as spatial, modal, and motivational warranting exploration.
The special issue aims to revisit and extend meaning theory in response to contemporary societal complexities, particularly the technological mediation of meaning through artificial intelligence and algorithmic systems, as well as challenges like polarization and meaninglessness. It invites interdisciplinary contributions that employ reflexivity and second-order observation to explore how meaning is currently being observed, transformed, and contested across different media and inter-systemic relations.
