Rational Solidarity and Functional Differentiation

The article is based on the idea that the problem of unity or integration of modern society has not yet been solved in sociological theory. The paper attempts a new solution based on a creative synthesis of elements from Talcott Parsons' functionalism, rational choice theory, and Niklas Luhmann's new systems theory. The core idea is that the state and the political sphere work together as an integrating centre of modern societies. Present approaches understand the political allocation of resources either as an exchange process or as solidarity caused by internalized social norms. None of them embodies a concept of collective rationality: therefore they cannot give a dynamic account of the public allocation of collective goods. This dichotomy of individual rationality and norm-guided behaviour will be produced and reproduced on the level of general theory in the discussion on the problem of order or collective action as long as sociology is founded on the assumption that society is made up of individual human beings and their actions. However, by replacing action with Luhmann's concept of communication and rethinking collective action within this new framework, it becomes possible to develop a concept of collective rationality. This new conceptualization is used to clear up problems and overcome shortcomings in Luhmann's own theory of modern society as functionally differentiated. Observed as a consequence of action, function is collective action. A solution to the problem of collective action or social order is found with the emergence of rational solidarity as a medium that symbolizes the difference between individual and collective rationality as a unity: one should sacrifice individual opportunities to achieve collective goals and solve problems for the society to which one belongs.
