Abstract
The author examines the role of discourse in a democratically organized society, where socially significant issues are resolved through collective discussion and criticism of the parties' claims. Discourse is considered as a practice of communicative relations aimed at achieving social harmony. It appears as the highest instance of social life, which determines norms, values and individual aspects of social life. However, there are also difficulties that Karl Otto Apel faces in justifying democracy, in particular in the context of the existence of "institutions of discourse". It is assumed that discourse as an institution should overcome the limits of other institutions. The author infers the ultimate nature of philosophical reasoning in transcendental pragmatics and insists on the defined institution of the transcendental language game as a meta-institution that encompasses rational conventions between social subjects.
