_Purpose__._ This article aims to analyse the ways of free communicative solution of civil society problems as a basis for the development of deliberative democracy on the example of the activities of volunteer organisations. _Theoretical basis._ The conceptual basis of the study is Immanuel Kant’s philosophical understanding of individual obligations as the basis for the institutionalisation of social communication. This concept is developed by Jürgen Habermas in the direction of deliberative democracy. Max Weber, Quentin Skinner, and other theorists give a (...) special status to language communication in the functioning of social institutions. Contemporary Ukrainian researchers analyse the volunteer movement as the basis for the communicative implementation of human freedom. _Originality__._ Practices of political performance in society contribute to the specific and contextual solution of the tasks of communication theory and provide answers to questions about sustainable human needs, on the one hand, and, on the other hand, contribute to solving the political problems of everyday life. Grassroots socio-political movements, and especially volunteer movements, practice free discussion of various social problems, which is the basis of the deliberative democracy. _Conclusions._ Overcoming value differences between members of society is more effective in deliberative practices as the core of social communication in a democratic society. The substantive way to find new forms of communication is to use deliberative practices of implementing freedom to improve the functioning of social institutions. The formal way is aimed at attracting the experience of volunteer organisations in using the minimum necessary forms of bureaucratisation of social institutions in a democratic society. (shrink)
