Jürgen Habermas (born June 18, 1929) is a German philosopher and sociologist in the tradition of critical theory and American pragmatism. He is best known for his work on the concept of the public sphere, which he has based in his theory of communicative action.
- 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.
- Habermas (1972) "Sprachspiel, intention und Bedeutung. Zu Motiven bei Sellars und Wittgenstein". In R.W. Wiggerhaus (Ed.) Sprachanalyse and Soziologie. Frankfurt: Suhrkamp). p. 334
- This is called the paradoxical achievement of intersubjectivity
- The speaker must choose a comprehensible [verstandlich] expression so that speaker and hearer can understand one another.

- 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.

- Norms appearing in the form of law entitle actors to exercise their rights or liberties. However, one cannot determine which of these laws are legitimate simply by looking at the form of individual rights. Only by bringing in the discourse principle can one show that each person is owed a right to the greatest possible measure of equal liberties that are mutually compatible.

- "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.

- As historical and social beings we find ourselves always already in a linguistically structured lifeworld. In the forms of communication through which we reach an understanding with one another about something in the world and about ourselves, we encounter a transcending power. Language is not a kind of private property. No one possesses exclusive rights over the common medium of the communicative practices we must intersubjectively share. No single participant can control the structure, or even the course, of processes of reaching understanding and self-understanding. How speakers and hearers make use of their communicative freedom to take yes- or no-positions is not a matter of their subjective discretion. For they are free only in virtue of the binding force of the justifiable claims they raise towards one another. The logos of language embodies the power of the intersubjective, which precedes and grounds the subjectivity of speakers.

- 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.

- 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 structural transformation of the public sphere, 1963/1991 
Habermas (1962/1989) The structural transformation of the public sphere: An inquiry into a category of bourgeois society. Translated by Thomas Burger.
- 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.
- 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.

- [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 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.
- 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.
- 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.
Knowledge and human Interests, 1971 
Habermas (1971) Knowledge and Human Interests, translated by J. Schapiro. Boston: Beacon Press.
- 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.
- 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.
- 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
- p. 266
- 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.
- [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.

Moral Consciousness and Communicative Action (1983) 
C. Lenhart and S. Nicholsen, trans. (Cambridge: 1995)
- What Kant regarded as a unique (Copernican) turn to transcendental reflection becomes in Hegel a general mechanism for turning consciousness back upon itself. This mechanism has been switched on and off time and time again in the development of spirit. As the subject becomes conscious of itself, it destroys one form of consciousness after another. This process epitomizes the subjective experience that what initially appears to the subject as a being in itself can become content only in the forms imparted to it by the subject. The transcendental philosopher’s experience is thus, according to Hegel, reenacted naively whenever an in-itself becomes a for-the-subject. What Hegel calls “Dialectical” is the reconstruction of this recurrent experience and of its assimilation by the subject, which gives rise to ever more complex structures. … Hegel, it should be noted, exposes himself to a criticism. … Reconstructing successive forms of consciousness is one thing. Proving the necessity of their succession is quite another.
- p. 5
- 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.
- p. 26
The Theory of Communicative Action, 1987 
- 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.
On The Pragmatics of Communication, 1998 
Jürgen Habermas & Maeve Cooke eds. (1998) On the Pragmatics of Communication. MIT Press.
- The task of universal pragmatics is to identify and reconstruct universal conditions of possible mutual understanding.
- 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.
- Reaching and understanding is the process of bringing about an agreement on the presupposed basis of validity claims that are mutually recognized.
About Habermas 
- Jurgen Habermas is widely considered as the most influential thinker in Germany over the past decade. As a philosopher and sociologist he has mastered and creatively articulated an extraordinary range of specialized literature in the social sciences, social theory and the history of ideas in the development of a comprehensive and provocative critical theory of knowledge and human interests. His roots are in the tradition of German thought from Kant to Marx, and he has been associated with the Frankfurt School of critical theorists which pioneered in the study of the relationship of the ideas of Marx and Freud.

- In Europe, you do philosophy by performing discourse on another guy's text, and so Derrida will go over Heidegger, and Habermas will extend Marx's corpus; but in America you could never get away with kinky stuff like that, for you have to generate philosophy from real things—like computers or television. You need to look at Omni magazine to get a feel for this new kind of mail-order, Popular Mechanics science of mind. It's full of articles about meditation helmets and downloading the soul into computers so that when your body wears out you can live forever. What is completely missing in Europe is precisely what you will find in America: namely, an electronic Umwelt in which history is replaced with movies, education is replaced with entertainment, and nature is replaced with technology. This peculiar wedding of low kitsch and high tech generates a posthistoric world that no European literary intellectual can quite fathom.
- William Irwin Thompson (1991) Fast Foreword, from The American Replacement of Nature
- Critical systems thinkers like Gerald Midgley identify three waves of systems thinking over the last 50 years or so. Early systems theorists (e.g. Bertalanffy) described systems in physical terms, resorting to metaphors from electronic computation or biology. This 'hard systems' tradition still has its advocates and practitioners... Subsequently the limits of the physical metaphor... were reached, and the secondwave of systems thinking developed. This 'soft systems thinking' employed social metaphors to develop appropriate systems approaches for human systems. The move to a more phenomenological, interpretative understanding of human systems, where meaning is central and is negotiated intersubjectively, parallels the new paradigm / crisis of social psychology of the 1970s. The Third wave, or critical systems school, in which Midgley locates himself, has drawn on the critical theory of Habermas, particularly in relation to theories of knowledge and of communicative rationality, and on the work of Foucault and followers on the nature of power.

- *"The strength of a culture depends on its capacity to open itself up to other cultures, to integrate itself into them and to integrate them into it. It doesn't matter how many differences there may be, Habermas pointed out, everyone shares some principles. No culture tolerates the exploitation of human beings. No religion permits the murder of innocent people. No civilisation accepts violence or terror."
- José Luis Rodríguez Zapatero (2005)
- Jürgen Habermas currently ranks as one of the most influential philosophers in the world. Bridging continental and Anglo-American traditions of thought, he has engaged in debates with thinkers as diverse as Gadamer and Putnam, Foucault and Rawls, Derrida and Brandom. His extensive written work addresses topics stretching from social-political theory to aesthetics, epistemology and language to philosophy of religion, and his ideas have significantly influenced not only philosophy but also political-legal thought, sociology, communication studies, argumentation theory and rhetoric, developmental psychology and theology. Moreover, he has figured prominently in Germany as a public intellectual, commenting on controversial issues of the day in German newspapers such as Die Zeit.
