Subjects who reciprocally recognize each other as such, must consider each other as identical, insofar as they both take up the position of subject; they must at all times subsume themselves and the other under the same category. At the same time, the relation of reciprocity of recognition demands the non-identity of one and the other, both must also maintain their absolute difference, for to be a subject implies the claim of individuation.

I shall develop the thesis that anyone acting communicatively must, in performing any speech act, raise universal validity claims and suppose that they can be vindicated.

The task of universal pragmatics is to identify and reconstruct universal conditions of possible mutual understanding.

As medium for reaching understanding, speech acts serve: a) to establish and renew interpersonal relations, whereby the speaker takes up a relation to something in the world of legitimate social orders; b) to represent states and events, whereby the speaker takes up a relation to something in the world of existing states of affairs; c) to manifest experiences that is, to represent oneself- whereby the speaker takes up a relation to something in the subjective world to which he has privileged access.

If we compare the third-person attitude of someone who simply says how things stand (this is the attitude of the scientist, for example) with the performative attitude of someone who tries to understand what is said to him (this is the attitude of the interpreter, for example), the implications ... become clear. ... First, interpreters relinquish superiority that observers have by virtue of their privileged position, in that they themselves are drawn, at least potentially, into negotiations about the meaning and validity of utterances. By taking part in communicative action, they accept in principle the same status as those whose utterances they are trying to understand. ... It is impossible to decide a priori who is to learn from whom.

Critical social science attempts to determine when theoretical statements grasp invariant regularities of social action as such and when they express ideologically frozen relations of dependence that can in principle be transformed.

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.

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.

Philosophy's position with regard to science, which at one time could be designated with the name "theory of knowledge," has been undermined by the movement of philosophical thought itself. Philosophy was dislodged from this position by philosophy.

Science can only be comprehended epistemologically, which means as one category of possible knowledge, as long as knowledge is not equated either effusively with the absolute knowledge of a great philosophy or blindly with scientistic self-understanding of the actual business of research.

Although objectively greater demands are placed on this authority, it operates less as a public opinion giving a rational foundation to the exercise of political and social authority, the more it is generated for the purpose of an abstract vote that amounts to no more than an act of acclamation within a public sphere temporarily manufactured for show or manipulation.

All affected can accept the consequences and the side effects that [the norm's] general observance can be anticipated to have for the satisfaction of everyone's interests, and the consequences are preferred to those of known alternative possibilities for regulation.

The bourgeois public sphere may be conceived above all as the sphere of private people come together as a public; they soon claimed the public sphere regulated from above against the public authorities themselves, to engage them in a debate over the general rules governing relations in the basically privatized but publicly relevant sphere of commodity exchange and social labor.

The usage of the words "public" and "public sphere" betrays a multiplicity of concurrent meanings. Their origins go back to various historical phases and, when applied synchronically to the conditions of a bourgeois society that is industrially advanced and constituted as a social-welfare state, they fuse into a clouded amalgam. Yet the very conditions that make the inherited language seem inappropriate appear to require these words, however confused their employment.

This investigation aims to analyze the type "bourgeois public sphere". Its particular approach is required, to begin with, by the difficulties specific to an object whose complexity precludes exclusive reliance on the specialized methods of a single discipline. Rather, the category. "public sphere" must be investigated within the broad field formerly reflected in the perspective of the traditional science of "politics."' When particular social-scientific discipline, this object disintegrates. The problems that result from fusing aspects of sociology and economics, of constitutional law and political science, and of social and intellectual history are obvious: given the present state of differentiation and specialization in the social sciences, scarcely anyone will be able to master several, let alone all, of these disciplines.

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.

Technically speaking, since our complex societies are highly susceptible to interferences and accidents,they certainly offer ideal opportunities for a prompt disruption of normal activities. These disruptions can, with minimum expense, have considerably destructive consequences. Global terrorism is extreme both in its lack of realistic goals and in its cynical exploitation of the vulnerability of complex systems.

I would in fact tend to have more confidence in the outcome of a democratic decision if there was a minority that voted against it, than if it was unanimous... Social psychology has amply shown the strength of this bandwagon effect.

Reaching and understanding is the process of bringing about an agreement on the presupposed basis of validity claims that are mutually recognized.
