The usage of the words “public" and “public sphere” betrays a multiplicity of concurrent meanings. Their origins go back to various historical phases… - Jürgen Habermas

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.

Christianity has functioned for the normative self-understanding of modernity as more than a mere precursor or a catalyst. Egalitarian universalism, from which sprang the ideas of freedom and social solidarity, of an antonomous conduct of life and emancipation, of the individual morality of conscience, human rights, and democracy, is the direct heir to the judaic ethic of justice and the Christian ethic of love. This legacy, substantially unchanged, has been the object of continual critical appropriation and reinterpretation. To this day, there is no alternative to it. And in the light of the current challenges of a postnational constellation, we continue to draw on the substance of this heritage. Everything else is just idle postmodern talk.

The only knowledge that can truly orient action is knowledge that frees itself from mere human interests and is based in Ideas—in other words knowledge that has taken a theoretical attitude.
