Political decisions made by a group of technically trained experts are an enigma to the classical, Aristotlean view of politics. There must also be an agreement among participants of the dialogue on the meaning of the words, gestures and symbols used in the dialogue and communications process. True communication is based on a shared understanding of the language used to convey messages. The social actions taken by the recipients of the expected positive results. It is the recipient of the service that makes the determination.
Emancipation is liberation resulting from social action.
That is, a people become emancipated, through their reflection and their own social action, from an oppressive, problematic, social situation. As a group, they rationally and freely determine the direction of their own lives by changing and improving their situation. Communicative action, both verbal and non-verbal, is based on a consensus that is taken for granted. Discourse is communication that results from this consensus being disturbed or disputed. Discourse, or the sharing of differences of opinions and beliefs, assists in testing the various claims of truth.
