The great German theorist Niklas Luhmann argued long ago that meaning is the central construct of sociology. We agree, but our scheme of stochastic processes—evolved over many years as identity and control—argues for switchings of intercalated bits of social network and interpretive domain as the core of meaning processes. We thus challenge Luhmann's central claim that modern society's subsystems are based on communicative self-closure. We assert that there is refuting evidence from sociolinguistics, from how languages are put together and how (...) languages' indexical and reflexive devices are used in social action. Communication is about managing indexicalities, which entail great ambiguity and openness as they are anchored in myriad netdom switchings across social times and spreads. In contrast, Luhmann's concept of communication revolves around binary codes governed recursively and algorithmically within systems in efforts to reduce complexity from the environment. We conclude that systems closure does not solve the problem of uncertainty in social life. In fact, lack of uncertainty is itself a problem. Order is necessary, but order at the edge of chaos.
