The speaker must choose a comprehensible [verständlich] expression so that speaker and hearer can understand one another. - Jürgen Habermas

The interpretation of a case is corroborated only by the successful continuation of a self-formative process, that is by the completion of self-reflection, and not in any unmistakable way by what the patient says or how he behaves

[According to Habermas, the genesis of the bourgeois public sphere resulted from a combination of early capitalist commercial development and the organization of territorial … Representative publicness involved a re-presenting or staging for the purposes of display and acclamation, hence] this publicness (or publicity) of representation was not constituted as a social realm, that is, as a public sphere; rather, it was something like a status attribute, if this term may be permitted.

The 'state' on the modern conception is a legally defined term which refers, at the level of substance, to a state power that possesses both internal and external sovereignty, at the spatial level over a clearly delimited terrain (the state territory) and at the social level over the totality of members (the body of citizens or the people). State power constitutes itself in the forms of positive law, and the people is the bearer of the legal order whose jurisdiction is restricted to the state territory. In political usage, the concepts 'nation' and 'people' have the same extension. But in addition to its legal definition, the term 'nation' has the connotation of a political community shaped by common descent, or at least by a common language, culture, and history. A people becomes a 'nation' in this historical sense only in the concrete form of a particular form of life.
