Jürgen Habermas currently ranks as one of the most influential philosophers in theworld. Bridging continental and Anglo-American traditions of thought, he hasengaged in debates with thinkers as diverse as Gadamer and Putnam, Foucault andRawls, Derrida and Brandom. His extensive written work addresses topicsstretching from social-political theory to aesthetics, epistemology and language tophilosophy of religion, and his ideas have significantly influenced not onlyphilosophy 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 DieZeit.

However, if one looks back over his corpus of work, one can discern two broadlines of enduring interest, one having to do with the political domain, the otherwith issues of rationality, communication, and knowledge.

1. The Early Development Of Habermas's InterestIn The Public Sphere And ReasonBorn outside Düsseldorf in 1929, Habermas came of age in postwar Germany. TheNuremberg Trials were a key formative moment that brought home to him thedepth of Germany's moral and political failure under National Socialism. Thisexperience was later reinforced when, as a graduate student interested inHeidegger's existentialism, he read the latter's reissued Introduction toMetaphysics, in which Heidegger had retained (or more accurately, reintroduced)an allusion to the “inner truth and greatness” of National Socialism (Heidegger1959, 199). When Habermas (1953) publicly called for an explanation fromHeidegger, the latter's silence confirmed Habermas's conviction that the Germanphilosophical tradition had failed in its moment of reckoning, providingintellectuals with the resources neither to understand nor to criticize NationalSocialism. This negative experience of the relation between philosophy andpolitics subsequently motivated his search for conceptual resources from Anglo-American thought, particularly its pragmatic and democratic traditions. In movingoutside the German tradition, Habermas joined a number of young postwarintellectuals such as Karl-Otto Apel (for Habermas's autobiographical sketch, see2005b, chap. 1).

Habermas completed his dissertation in 1954 at the University of Bonn, writing onthe conflict between the absolute and history in Schelling's thought. He first gainedserious public attention, at least in Germany, with the 1962 publication of hishabilitation, Strukturwandel der Öffentlichkeit (Structural Transformation of thePublic Sphere; English ed., 1989), a detailed social history of the development ofthe bourgeois public sphere from its origins in the 18th century salons up to itstransformation through the influence of capital-driven mass media. In hisdescription of the salons we clearly see his interest in a communicative ideal thatlater would provide the core normative standard for his moral-political theory: theidea of inclusive critical discussion, free of social and economic pressures, inwhich interlocutors treat each other as equals in a cooperative attempt to reach anunderstanding on matters of common concern. As an ideal at the center ofbourgeois culture, this kind of interchange was probably never fully realized;nonetheless, it “was not mere ideology” (1989, 160, also 36). As these smalldiscussion societies grew into mass publics in the 19th century, however, ideas

became commodities, assimilated to the economics of mass media consumption.Rather than give up on the idea of public reason, Habermas called for asocioinstitutionally feasible concept of public opinion-formation “that ishistorically meaningful, that normatively meets the requirements of the social-welfare state, and that is theoretically clear and empirically identifiable.” Such aconcept “can be grounded only in the structural transformation of the publicsphere itself and in the dimension of its development” (ibid., 244). His concludingsketch of such a concept (ibid., 244–48) already contains in outline the two-levelmodel of democratic deliberation he later elaborates in his mature work on law anddemocracy, Between Facts and Norms (1996b; German ed., 1992b).

Habermas's interest in the political subsequently led him to a series ofphilosophical studies and critical-social analyses that eventually appeared inEnglish in his Toward a Rational Society (1970) and Theory and Practice (1973b).Whereas the latter consists primarily of reflections on the history of philosophy,the former represents an attempt to apply his emerging theory of rationality to thecritical analysis of contemporary society, in particular the student protestmovement and its institutional target, the authoritarian and technocratic structuresthat held sway in higher education and politics.

Habermas's critical reflection takes a nuanced approach to both sides of the socialunrest that characterized the late sixties. Although sympathetic with students'demand for more democratic participation and hopeful that their activism harboreda potential for positive social transformation, he also did not hesitate to criticize itsmilitant aspects, which he labeled self-delusory and “pernicious” (1970, 48). In hiscritique of technocracy—governance by scientific experts and bureaucracy—herelied on a philosophical framework that anticipates categories in his later thought,minus the philosophy of language he would work out in the 1970s. Specifically,Habermas (ibid., chap. 6) sharply distinguished between two modes of action,“work” and “interaction,” which correspond to enduring interests of the humanspecies. The former includes modes of action based on the rational choice ofefficient means, that is, forms of instrumental and strategic action, whereas thelatter refers to forms of “communicative action” in which actors coordinate theirbehaviors on the basis of “consensual norms” (ibid., 91–92). Habermas'sdistinction in effect appropriates the classical Aristotelian contrast between techneand praxis for critical social theory (1973b, chap. 1). The result is a distinctivelyHabermasian critique of science and technology as ideology: by reducing practicalquestions about the good life to technical problems for experts, contemporaryelites eliminate the need for public, democratic discussion of values, therebydepoliticizing the population (1970, chap. 6). The legitimate human interest intechnical control of nature thus functions as an ideology—a screen that masks the

value-laden character of government decisionmaking in the service of the capitaliststatus quo. Unlike Herbert Marcuse, who regarded that interest as specific tocapitalist society, Habermas affirmed the technical control of nature as a genuinelyuniversal species-interest; unlike Horkheimer and Adorno in their Dialectic ofEnlightenment, the technical interest did not necessitate social domination.

Habermas defended this philosophical anthropology most fully in his Knowledgeand Human Interests (1971b; German ed., 1968b), the work that represents hisfirst attempt to provide a systematic framework for critical social theory. In it,Habermas develops a theory of “knowledge-constitutive interests” that are tiedboth to “the natural history of the human species” and to “the imperatives of thesocio-cultural form of life,” but are not reducible to them (ibid., 168). There arethree knowledge-constitutive interests, each tied to a particular conception ofscience and social science. The first is the “technical interest,” the“anthropologically deep-seated interest” we have in the prediction and control ofthe natural environment. Positivism sees knowledge in these terms, andnaturalistic accounts of human possibilities often regard human history only fromthis point of view. Second, there is the equally deep-seated “practical interest” insecuring and expanding possibilities of mutual and self-understanding in theconduct of life. Finally, there is the “emancipatory interest” in overcomingdogmatism, compulsion, and domination.

If each interest is constitutive of a form of knowledge, then we should expect tofind for each a corresponding form of cultural-institutional realization, that is,organized modes of inquiry and knowledge-production. This seems to be plausiblefor the interests in control of nature and social understanding: the empirical-analytic sciences are oriented toward instrumental action and technical controlunder specified conditions, and the cultural-hermeneutic sciences presuppose andarticulate modes of action-orienting (inter)personal understanding that operatewithin socio-cultural forms of life and the grammar of ordinary language. Inretrospect, Habermas's analysis of these two interests is limited by the concerns ofthe day. His distinction between the sciences that take nature as their object, andinterpretive modes of inquiry that depend on communicative access to domains ofhuman life, still has some plausibility. But his view of the natural sciences still hadnot fully absorbed the lessons of post-positivist science studies. Nor is it clear thatprediction and control exhaust the interests that drive the natural sciences (e.g., theinterest in the geologic past seems to involve more than technical control).

The status of the emancipatory interest, however, was problematic from the start.Habermas broadly identified it as the interest of reason as such, which underliescritical-reflective knowledge. However, Habermas soon realized he had conflated

two forms of critical reflection: the critique that aims to unmask self-deception andideology and the reflective articulation of the formal structures of knowledge(1973cd). Moreover, the interest in emancipation does not clearly correspond to aspecific science or form of institutionalized inquiry. Although Freudianpsychology and Marxist social theory have such an interest, much if not mostpsychological and sociological inquiry does not have explicitly emancipatoryaims, but rather is driven by interests in prediction and social understanding. Norwas it clear that psychoanalysis provided an apt model of liberatory reflection inany case, as critics pointed out how the asymmetries between patient and analystcould not represent the proper intersubjective form for emancipation. Thesedeficits posed a challenge for Habermas that would guide a decades-long searchfor the normative and empirical basis of critique. Whatever the best path to theepistemic and normative basis for critique might be, it would have to pass ademocratic test: that “in Enlightenment there are only participants” (1973b, 44).Habermas will not resolve this methodological issue until a series of transitionalstudies in the 1970s culminates in his mature systematic work, The Theory ofCommunicative Action (1984a/1987; German ed., 1981; hereafter cited as TCA).

That said, we can discern enduring features in Habermas's early attempt at acomprehensive model of social criticism. As a theory of rationality andknowledge, his theory of knowledge-constitutive interests is both pragmatic andpluralistic: pragmatic, inasmuch as human interests constitute knowledge;pluralistic, in that different forms of inquiry and knowledge emerge from differentcore interests. In Knowledge and Human Interests we can thus see the beginningsof a methodologically pluralistic approach to critical social theory, more on whichbelow. Besides the problems described above, however, the analysis was hamperedby a framework that still relied on motifs from a “philosophy of consciousness”fixated on the constitution of objects of possible experience—an approach thatcannot do justice to the discursive dimensions of inquiry (1973cd; 2000; alsoMüller-Doohm 2000). In the 1970s Habermas set about a fundamental overhaul ofhis framework for critical theory (see McCarthy 1978).

2. Important Transitional WorksIn the period between Knowledge and Human Interests and The Theory ofCommunicative Action, Habermas began to develop a distinctive method forelaborating the relationship between a theoretical social science of modernsocieties, on the one hand, and the normative and philosophical basis for critique,on the other. Following Horkheimer's definition of Critical theory, Habermaspursued three aims in his attempt to combine social science and philosophical

analysis: it must be explanatory, practical, and normative, all at the same time.This meant that philosophy could not, as it did for Kant, become the sole basis fornormative reflection. Rather, Habermas argued, adequate critique requires athoroughgoing cooperation between philosophy and social science. This sort ofanalysis is characteristic of Legitimation Crisis (1975; German ed., 1973e), inwhich Habermas analyzes the modern state as subject to endemic crises, whicharise from the fact that the state cannot simultaneously meet the demands forrational problem solving, democracy, and cultural identity. Here the social scienceto which Habermas appeals is more sociological and functional. Similarly, in thiswork and in Communication and the Evolution of Society (1979), Habermasbegins to develop a distinctive conception of rational reconstruction, which modelssocietal development as a learning process. In these works, Habermas begins toincorporate the results of developmental psychology, which aligns stages ofdevelopment with changes in the kinds of reasons that the maturing individualconsiders acceptable. Analogously, societies develop through similar changes inthe rational basis of legitimacy on the collective level. At this point in histheorizing, Habermas's appropriation of the social sciences has becomemethodologically and theoretically pluralistic: on his view, a critical social theoryis not distinctive in light of endorsing some particular theory or method but asuniting normative and empirical inquiry.

In this transitional phase from Knowledge and Human Interests to The Theory ofCommunicative Action, Habermas's basic philosophical endeavor was to develop amore modest, fallibilist, empirical account of the philosophical claim touniversality and rationality. This more modest approach rids Critical Theory of itsvestiges of transcendental philosophy, pushing it in a naturalistic,“postmetaphysical” direction (1988b). Such a naturalism identifies more specificforms of social-scientific knowledge that help in developing an analysis of thegeneral conditions of rationality manifested in various human capacities andpowers.

Habermas's encounter with speech act theory proved to be particularly decisive forthis project. In speech act theory, he finds the basis for a conception ofcommunicative competence (on the model of Chomsky's linguistic competence).Given this emphasis on language, Habermas is often said to have taken a kind of“linguistic turn” in this period. He framed his first essays on formal pragmatics(1976ab) as an alternative to Niklas Luhmann's systems theory. Habermasunderstands formal pragmatics as one of the “reconstructive sciences,” which aimto render theoretically explicit the intuitive, pretheoretical know-how underlyingsuch basic human competences as speaking and understanding, judging and acting.Unlike Kant's transcendental analysis of the conditions of rationality,

reconstructive sciences yield knowledge that is not necessary but hypothetical, nota priori but empirical, not certain but fallible. They are nevertheless directed toinvariant structures and conditions and raise universal, but defeasible claims to anaccount of practical reason.

With the turn to language and reconstructive science, Habermas undermines bothof the traditional Kantian roles for philosophy: philosophy as the sole judge innormative matters and as the methodological authority that assigns the variousdomains of inquiry to their proper questions. In Habermas's view, philosophy mustengage in a fully cooperative relationship with the social sciences and theempirical disciplines in general. This step is completed in The Theory ofCommunicative Action, to which we now turn.

3. Mature PositionsTo understand Habermas's mature positions, we must start with his Theory ofCommunicative Action (TCA), a two-volume critical study of the theories ofrationality that informed the classical sociologies of Weber, Durkheim, Parsons,and neo-Marxist critical theory (esp. Lukács, Horkheimer, Adorno). Moreimportantly, in TCA we find Habermas's conception of the task of philosophy andits relation to the social sciences—a conception that still guides much of his work.While TCA defends the emphasis on normativity and the universalist ambitionsfound in the philosophical tradition, it does so within a framework that includesparticular sorts of empirical social research, with which philosophy must interact.Philosophers, that is, must cooperate with social scientists if they are to understandnormative claims within the current historical context, the context of a complex,modern society that is characterized by social and systemic modes of integration.The problem with pessimistic social theories of modernity is that they miss thecultural dimension of modernization due to a one-sided, primarily instrumentalconception of rationality.

3.1 The Theory of Communicative Action

Starting with Marx's historical materialism, large-scale macrosociological andhistorical theories have long been held to be the most appropriate explanatorybasis for critical social science. However, such theories have two drawbacks forthe critical project. First, comprehensiveness does not ensure explanatory power.Indeed, there are many such large-scale theories, each with their own distinctiveand exemplary social phenomena that guide their attempt at unification. Second, aclose examination of standard critical explanations, such as the theory of ideology,shows that such explanations typically appeal to a variety of different social

Page 8: A

theories (Bohman 1999). Habermas's actual employment of critical explanationsbears this out. His criticism of modern societies turns on the explanation of therelationship between two very different theoretical terms: a micro-theory ofrationality based on communicative coordination and a macro-theory of thesystemic integration of modern societies through such mechanisms as the market(TCA, vol. 2). In concrete terms, this means that Habermas develops a two-levelsocial theory that includes an analysis of communicative rationality, the rationalpotential built into everyday speech, on the one hand; and a theory of modernsociety and modernization, on the other (White 1989). On the basis of this theory,Habermas hopes to be able to assess the gains and losses of modernization and toovercome its one-sided version of rationalization.

Comprehensive critical theories make two problematic assumptions: that there isone preferred mode of critical explanation, and that there is one preferred goal ofsocial criticism, namely a socialist society that fulfills the norm of humanemancipation. Only with such a goal in the background does the two-step processof employing historical materialism to establish an epistemically and normativelyindependent stance make sense. The correctness or incorrectness of such a criticalmodel depends not on its acceptance or rejection by its addressees, but on theadequacy of the theory to objective historical necessities or mechanisms (intowhich the critical theorist alleges to have superior insight). A pluralistic mode ofcritical inquiry suggests a different norm of correctness: that criticism must beverified by those participating in the practice and that this demand for practicalverification is part of the process of inquiry itself.

Although Habermas's attitude toward these different modes of critical theory issomewhat ambivalent, he has given good reasons to accept the practical, pluralistapproach. Just as in the analysis of modes of inquiry tied to distinct knowledge-constitutive interests, Habermas accepts that various theories and methods eachhave “a relative legitimacy.” Indeed, like Dewey he goes so far as to argue that thelogic of social explanation is pluralistic and eludes the “apparatus of generaltheories.” In the absence of any such general theories, the most fruitful approach tosocial-scientific knowledge is to bring all the various methods and theories intorelation to each other: “Whereas the natural and the cultural or hermeneuticsciences are capable of living in mutually indifferent, albeit more hostile thanpeaceful coexistence, the social sciences must bear the tension of divergentapproaches under one roof” (1988a, 3). In TCA, Habermas casts critical socialtheory in a similarly pluralistic, yet unifying way. In discussing various accountsof societal modernization, for example, he argues that the main existing theorieshave their own “particular legitimacy” as developed lines of empirical research,and that Critical Theory takes on the task of critically unifying the various theories

and their heterogeneous methods and presuppositions. “Critical social theory doesnot relate to established lines of research as a competitor; starting from its conceptof the rise of modern societies, it attempts to explain the specific limitations andthe relative rights of those approaches” (TCA, 2: 375).

To achieve these theoretical and methodological ends, Habermas begins this taskwith a discussion of theories of rationality and offers his own distinctive definitionof rationality, one that is epistemic, practical, and intersubjective. For Habermas,rationality consists not so much in the possession of particular knowledge, butrather in “how speaking and acting subjects acquire and use knowledge” (TCA, 1:11). Any such account is “pragmatic” because it shares a number of distinctivefeatures with other views that see interpreters as competent and knowledgeableagents. Most importantly, a pragmatic approach develops an account of practicalknowledge in the “performative attitude,” that is, from the point of view of acompetent speaker. A theory of rationality thus attempts to reconstruct thepractical knowledge necessary for being a knowledgeable social actor among otherknowledgeable social actors. As already mentioned, Habermas's reconstructionattempts to articulate invariant structures of communication, and so qualifies as a“formal pragmatics.”

What is the “performative attitude” that is to be reconstructed in such a theory?From a social-scientific point of view, language is a medium for coordinatingaction, although not the only such medium. The fundamental form of coordinationthrough language, according to Habermas, requires speakers to adopt a practicalstance oriented toward “reaching understanding,” which he regards as the“inherent telos” of speech. When actors address one another with this sort ofpractical attitude, they engage in what Habermas calls “communicative action,”which he distinguishes from strategic forms of social action. Because thisdistinction plays a fundamental role in TCA, it deserves some attention.

In strategic action, actors are not so much interested in mutual understanding as inachieving the individual goals they each bring to the situation. Actor A, forexample, will thus appeal to B's desires and fears so as to motivate the behavior onB's part that is required for A's success. As reasons motivating B's cooperation, B'sdesires and fears are only contingently related to A's goals. B cooperates with A, inother words, not because B finds A's project inherently interesting or worthy, butbecause of what B gets out of the bargain: avoiding some threat that A can make orobtaining something A has promised (which may be of inherent interest to B butfor A is only a means of motivating B).

In communicative action, or what Habermas later came to call “strong

Page 10: A

communicative action” in “Some Further Clarifications of the Concept ofCommunicative Rationality” (1998b, chap. 7; German ed., 1999b), speakerscoordinate their action and pursuit of individual (or joint) goals on the basis of ashared understanding that the goals are inherently reasonable or merit-worthy.Whereas strategic action succeeds insofar as the actors achieve their individualgoals, communicative action succeeds insofar as the actors freely agree that theirgoal (or goals) is reasonable, that it merits cooperative behavior. Communicativeaction is thus an inherently consensual form of social coordination in which actors“mobilize the potential for rationality” given with ordinary language and its telosof rationally motivated agreement.

To support his conception of communication action, Habermas must specify themechanism that makes rationally motivated agreement possible. Toward that end,he argues for a particular account of utterance meaning as based on “acceptabilityconditions,” by analogy to the truth-conditional account of the meaning ofsentences. But rather than linking meaning with representational semantics,Habermas takes a pragmatic approach, analyzing the conditions for theillocutionary success of the speech act. According to the core principle of hispragmatic theory of meaning, “we understand a speech act when we know thekinds of reasons that a speaker could provide in order to convince a hearer that heis entitled in the given circumstances to claim validity for his utterance—in short,when we know what makes it acceptable” (1998b, 232). With this principle,Habermas ties the meaning of speech acts to the practice of reason giving: speechacts inherently involve claims that are in need of reasons—claims that are open toboth criticism and justification. In our everyday speech (and in much of ouraction), speakers tacitly commit themselves to explaining and justifyingthemselves, if necessary. To understand what one is doing in making a speech act,therefore, one must have some sense of the appropriate response that would justifyone's speech act, were one challenged to do so. A speech act succeeds in reachingunderstanding when the hearer takes up “an affirmative position” toward the claimmade by the speaker (TCA 1: 95–97; 282; 297). In doing so, the hearer presumesthat the claims in the speech act could be supported by good reasons (even if shehas not asked for them). When the offer made by the speaker fails to receiveuptake, speaker and hearer may shift reflexive levels, from ordinary speech to“discourse”—processes of argumentation and dialogue in which the claimsimplicit in the speech act are tested for their rational justifiability as true, correct orauthentic. Thus the rationality of communicative action is tied to the rationality ofdiscourse, more on which in section 3.2.

What are these claims that are open to criticism and justification? In opposition tothe positivist fixation on fact-stating modes of discourse, Habermas does not limit

Page 11: A

intersubjectively valid, or justifiable, claims to the category of empirical truth, butinstead recognizes a spectrum of “validity claims” that also includes, at the least,claims to moral rightness, ethical goodness or authenticity, personal sincerity, andaesthetic value (TCA 1: 8–23; 1993, chap. 1). Although Habermas does notconsider such claims to represent a mind-independent world in the manner ofempirical truth claims, they can be both publicly criticized as unjustifiable anddefended by publicly convincing arguments. To this extent, validity involves anotion of correctness analogous to the idea of truth. In this context, the phrase“validity claim,” as a translation of the German term Geltungsanspruch, does nothave the narrow logical sense (truth-preserving argument forms), but ratherconnotes a richer social idea—that a claim (statement) merits the addressee'sacceptance because it is justified or true in some sense, which can vary accordingto the sphere of validity and dialogical context.

By linking meaning with the acceptability of speech acts, Habermas moves theanalysis beyond a narrow focus on the truth-conditional semantics ofrepresentation to the social intelligibility of interaction. The complexity of socialinteraction then allows him to find three basic validity claims potentially at stakein any speech act used for cooperative purposes (i.e., in strong communicativeaction). His argument relies on three “world relations” that are potentially involvedin strongly communicative acts in which a speaker intends to say something tosomeone about something (TCA 1: 275ff). For example, a constative (fact-stating)speech act (a) expresses an inner world (an intention to communicate a belief); (b)establishes a communicative relation with a hearer (and thus relates to a socialworld, specifically one in which both persons share a piece of information, andknow they do); and (c) attempts to represent the external world. This triadicstructure suggests that many speech acts, including non-constatives, involve a setof tacit validity claims: the claim that the speech act is sincere (non-deceptive), issocially appropriate or right, and is factually true (or more broadly:representationally adequate). Conversely, speech acts can be criticized for failingon one or more of these scores. Thus fully successful speech acts, insofar as theyinvolve these three world relations, must satisfy the demands connected with thesethree basic validity claims (sincerity, rightness, and truth) in order to beacceptable.

We can think of strong communicative action in the above sense as defining theend of a spectrum of communicative possibilities. At that end, social cooperationis both deeply consensual and reasonable: actors sincerely agree that their modesof cooperation can be justified as good, right, and free of empirical error. Given thedifficulties of maintaining such deep consensus, however, it makes sense,particularly in complex, pluralistic societies, to relax these communicative

Page 12: A

demands for specified types of situations, allowing for weaker forms ofcommunicative action (in which not all three types of validity claims are at stake)or strategic action (in which actors understand that everyone is oriented towardindividual success).

Habermas distinguishes the “system” as those predefined situations, or modes ofcoordination, in which the demands of communicative action are relaxed in thisway, within legally specified limits. The prime examples of systemic coordinationare markets and bureaucracies. In these systemically structured contexts,nonlinguistic media take up the slack in coordinating actions, which proceeds onthe basis of money and institutional power—these media do the talking, as it were,thus relieving actors of the demands of strongly communicative action. The term“lifeworld,” by contrast, refers to domains of action in which consensual modes ofaction coordination predominate. In fact, the distinction between lifeworld andsystem is better understood as an analytic one that identifies different aspects ofsocial interaction and cooperation (1991b). “Lifeworld” then refers to thebackground resources, contexts, and dimensions of social action that enable actorsto cooperate on the basis of mutual understanding: shared cultural systems ofmeaning, institutional orders that stabilize patterns of action, and personalitystructures acquired in family, church, neighborhood, and school (TCA 1: chap. 6;1998b, chap. 4).

As a theory of meaning, TCA has encountered rather heavy weather. In the analyticphilosophy of language, one of the standard requirements is to account for thecompositionality of language, the fact that a finite set of words can be used to forman indefinite number of sentences. From that perspective, Habermas's theory fallsshort (Heath 2001, chap. 3). But perhaps we would do better to assess Habermas'stheory of meaning from a different perspective. The compositionality requirementis important if one wants to explain grammatical competence. But early onHabermas (1976b) expressed a greater interest in explaining communicative,rather than grammatical, competence: the ability of speakers to use grammaticallywell-formed sentences in social contexts. Although Habermas often presents hispragmatics as a further development in analytic theories of meaning, his analysisfocuses primarily on the context-sensitive acceptability of speech acts:acceptability conditions as a function of formal features that distinguish differentspeech situations. This suggests his theory of meaning involves a quite differentsort of project: to articulate the “validity basis” of social order.

The significance of this conception of reaching understanding and of rationallymotivated agreement can also be seen by contrasting this account with otherconceptions of understanding and interpretation, such as Gadamer's hermeneutics.

Given Habermas's conception of speech acts and their relation to validity claims, itis not surprising that he argues that “communicative actions always requireinterpretations that are rational in approach” (TCA 1: 106), that is, ones that aremade in the performative attitude by an interpreter. In general, Habermas agreeswith hermeneutics that the whole domain of the social sciences is accessible onlythrough interpretation, precisely because processes of reaching understandingalready at work in the social sciences have antecedently constituted them (ibid.,107). But he draws a distinctive conclusion. Although social scientists are notactors, they must employ their own pretheoretical knowledge to gain interpretiveaccess through communicative experience. As a “virtual participant,” the socialscientist must take a position on the claims made by those he observes: he hasaccess through communicative experience only “under the presupposition that hejudges the agreement and disagreement, the validity claims and potential reasonswith which he is confronted” (ibid., 116). There is then no disjunction between theattitude of the critic and the interpreter as reflective participants. Social scientistsmay withhold judgments, but only at the cost of impoverishing their interpretationand putting out of play their pretheoretical, practical knowledge that they have incommon with others who are able to reach understanding. Thus, various forms ofrationality become essential to the social sciences, because of the nature of thesocial domain.

Objecting to Habermas's line of argument, McCarthy and others have argued thatit is not a necessary condition that interpreters take a position in order tounderstand reasons, even if we have to rely on our own competence to judge thevalidity and soundness of reasons and to identify them as reasons at all.Nonetheless, Habermas uses this conception in his social theory of modernity toshow the ways in which modern culture has unleashed communicative rationalityfrom its previous cultural and ideological constraints. In modern societies, socialnorms are no longer presumed to be valid but rather are subjected to criticalreflection, as for example when the ethical life of a specific culture is criticizedfrom the standpoint of justice. In a sense consistent with the Enlightenmentimperative to use one's own reason, the everyday “lifeworld” of social experiencehas been rationalized, especially in the form of discourses that institutionalizereflective communicative action, as in scientific and democratic institutions.

The rationalization of the lifeworld in Western modernity went hand-in-hand withthe growth of systemic mechanisms of coordination already mentioned above, inwhich the demands on fully communicative consensus are relaxed. If large andcomplex modern societies can no longer be integrated solely on the basis of sharedcultural values and norms, new nonintentional mechanisms of coordination mustemerge, which take the form of nonlinguistic media of money and power.

example, markets coordinate the collective production and distribution of goodsnonintentionally, even if they are grounded in cultural and political institutionssuch as firms and states. Modernization can become pathological, as when moneyand power “colonize the lifeworld” and displace communicative forms ofsolidarity and inhibit the reproduction of the lifeworld, as when, for example,universities become governed by market strategies. “Juridification” is another suchpathological form, when law comes to invade more and more areas of social life,turning citizens into clients of bureaucracies with what Foucault might call“normalizing” effects. This aspect of TCA has less of an impact on Habermas'scurrent work, which returns to the theme of improving democratic practice as ameans of counteracting juridification and colonization. Democratic institutions, ifproperly designed and robustly executed, are supposed to ensure that the law doesnot take this pathological form but is subject to the deliberation of citizens, whothus author the laws to which they are subject (see sec. 3.4).

After TCA, then, Habermas begins to see law not as part of the problem, but aspart of the solution, once he offers a more complete discourse-theoretical accountof law and democracy. Nonetheless the theory of modernity still remains in hiscontinued use of systems theory and its understanding of nonintentionalintegration. By insisting upon popular sovereignty as the outcome of thegeneration of “communicative power” in the public sphere, Habermas tries to savethe substance of radical democracy. The unresolved difficulty is that in a complexsociety, as Habermas asserts, “public opinion does not rule” but rather pointsadministrative power in particular directions; or, as he puts it, it does not “steer”but “countersteers” institutional complexity (1996b, chapter 8). That is, citizens donot control social processes; they exercise influence through particularinstitutionalized mechanisms and channels of communication. However successfuldemocracy is in creating legitimacy, it cannot gain full control over large-scalecomplex societies, nor even of the necessary conditions for its own realization. Inthis sense, Habermas's emphasis on the limiting effect of complexity ondemocracy and his rejection of a fully democratic form of sociation continue thebasic argument of the necessity of systems integration, even with its costs. Radicaldemocracy may no longer be the only means to social transformation, though it isclear that it remains “the unfinished project of modernity”: realizing andtransforming democracy is still a genuine goal even for complex and globalizingsocieties.

3.2 Habermas's Discourse Theory

Habermas's theory of communicative action rests on the idea that social orderultimately depends on the capacity of actors to recognize the intersubjective

Page 15: A

validity of the different claims on which social cooperation depends. In conceivingcooperation in relation to validity claims, Habermas highlights its rational andcognitive character: to recognize the validity of such claims is to presume thatgood reasons could be given to justify them in the face of criticism. TCA thuspoints to and depends on an account of such justification—that is, on a theory ofargumentation or discourse, which Habermas calls the “reflective form” ofcommunicative action.

As mentioned above, Habermas proposes a multi-dimensional conception ofreason that expresses itself in different forms of cognitive validity: not only intruth claims about the empirical world, but also in rightness claims about the kindof treatment we owe each other as persons, authenticity claims about the good life,technical-pragmatic claims about the means suitable to different goals, and so on.As he acknowledges, the surface grammar of speech acts does not suffice toestablish this range of validity types. Rather, to ground the multi-dimensionalsystem of validity claims, one must supplement semantic analysis with apragmatic analysis of the different sorts of argumentative discourse—the different“logics of argumentation”—through which each type can be intersubjectivelyjustified (TCA 1: 8–42). Thus, a type of validity claim counts as distinct from othertypes only if one can establish that its discursive justification involves features thatdistinguish it from other types of justification. Whether or not his pragmatic theoryof meaning succeeds, the discursive analysis of validity illuminates importantdifferences in the argumentative demands that come with different types ofjustifiable claims. To see how Habermas identifies these different features, it is firstnecessary to understand the general structures of argumentation.

The pragmatic analysis of argumentation in general. Habermas's discourse theoryassumes that the specific type of validity claim one aims to justify—the cognitivegoal or topic of argumentation—determines the specific argumentative practicesappropriate for such justification. Discourse theory thus calls for a pragmaticanalysis of argumentation as a social practice. Such analysis aims to reconstructthe normative presuppositions that structure the discourse of competent arguers.To get at these presuppositions, one cannot simply describe argumentation as itempirically occurs; as we already saw in TCA, one must adopt the performativeattitude of a participant and articulate the shared, though often tacit, ideals andrules that provide the basis for regarding some arguments as better than others.Following contemporary argumentation theorists, Habermas assumes one cannotfully articulate these normative presuppositions solely in terms of the logicalproperties of arguments. Rather, he distinguishes three aspects of argument-making practices: argument as product, as procedure, and as process, which heloosely aligns with the traditional perspectives on argument evaluation of logic,

Jürgen Habermas (Stanford Encyclopedia of Philosophy) http://plato.stanford.edu/entries/habermas/

15 of 40 1/22/10 6:25 PM

Page 16: A

dialectic, and rhetoric. Pragmatically, each of these perspectives functions as a“level of presupposition” involved in the assessment of the cogency—thegoodness or strength—of arguments. Habermas seems to regard theseperspectives, taken together, as constituting the pragmatic idea of cogency: “at nosingle one of these analytic levels can the very idea intrinsic to argumentativespeech be adequately developed” (TCA 1: 26).

At the logical level, participants are concerned with arguments as products, that is,sets of reasons that support conclusions. From this perspective, arguers aim toconstruct “cogent arguments that are convincing in virtue of their intrinsicproperties and with which validity claims can be redeemed or rejected” (ibid., 25).Following work by Stephen Toulmin and other informal logicians, Habermasregards most if not all argumentation as ultimately resting on ampliative argumentswhose conclusions do not follow with deductive certainty but only as more or lessplausible or probable. The logical strength of such arguments depends on how wellone has taken into account all the relevant information and possible objections.Thus the term “logical” has a broad sense that includes not only formal but alsoinformal logics, in which strength depends on the interrelated meanings of termsand background information that resists complete formalization: induction,analogy, narrative, and so on.

Given the ampliative character of most arguments, logical assessment presupposesthe dialectical adequacy of argumentative procedures. That is, we may regard theproducts of our argument-making practices as logically strong only if we presume,at the dialectical level, that we have submitted arguments and counterarguments tosufficiently severe procedures of critical discussion—as Habermas (TCA 1: 26)puts it, a “ritualized competition for the better arguments.” Dialectical treatmentsof argumentation typically spell out the “dialectical obligations” of discussants:that one should address the issue at hand, should respond to relevant challenges,meet the specified burden of proof, and so on.

However, robust critical testing of competing arguments depends in turn on therhetorical quality of the persuasive process. Habermas conceives the rhetoricallevel in terms of highly idealized properties of communication, which he initiallypresented as the conditions of an “ideal speech situation” (1973a; also 1971/2001).That way of speaking now strikes him as overly reified, suggesting an idealcondition that real discourses must measure up to, or at least approximately satisfy—motifs that Habermas himself employed until rather recently (cf. 1993, 54–55;1996b, 322–23). He now understands the idea of rhetorically adequate process as aset of unavoidable yet counterfactual “pragmatic presuppositions” that participantsmust make if they are to regard the actual execution of dialectical procedures as a

Page 17: A

sufficiently severe critical test. Habermas (2005b, 89) identifies four suchpresuppositions as the most important: (i) no one capable of making a relevantcontribution has been excluded, (ii) participants have equal voice, (iii) they areinternally free to speak their honest opinion without deception or self-deception,and (iv) there are no sources of coercion built into the process and procedures ofdiscourse. Such conditions, in effect, articulate what it would mean to assess allthe relevant information and arguments (for a given level of knowledge andinquiry) as reasonably as possible, weighing arguments purely on the merits in adisinterested pursuit of truth. These conditions are counterfactual in the sense thatactual discourses can rarely realize—and can never empirically certify—fullinclusion, non-coercion, and equality. At the same time, these idealizingpresuppositions have an operative effect on actual discourse: we may regardoutcomes (both consensual and non-consensual) as reasonable only if our scrutinyof the process does not uncover obvious exclusions, suppression of arguments,manipulation, self-deception, and the like (2003a, 108). In this sense, thesepragmatic idealizations function as “standards for a self-correcting learningprocess” (2005b, 91).

As an understanding of the rhetorical perspective, Habermas's highly idealized andformal model hardly does justice to the substantive richness of the rhetoricaltradition. One can, however, supplement his model with a more substantiverhetoric that draws on Aristotle's account of ethos and pathos (Rehg 1997). In thatcase, the rhetorical perspective is concerned with designing arguments for theirability to place the particular audience in the proper social-psychological space formaking a responsible collective judgment. But the “space of responsiblejudgment” still remains an idealization that may not be reduced to any observableactual behavior, but can at most be defeasibly presumed. The same probably holdsfor dialectical procedures. Although the dialectical perspective draws on thetradition of public debate, dialectical norms, when understood as pragmaticpresuppositions, are not identical with institutionalized rules of debate (1990a, 91).A neutral observer can judge whether interlocutors have externally complied withinstitutional procedures, whereas engaged participants must judge how well theyhave satisfied the dialectical presupposition of severe critical testing.

The differentiation of argumentative discourses. If the different validity claimsrequire different types of argumentation, then the relevant differences must emergethrough a closer analysis of the ways the above aspects of argumentative practiceadjust to different sorts of content, that is, the different validity claims at issue (cf.2005b, chap. 3). To be sure, Habermas does not regard every validity claim asopen to discourse proper. Sincerity claims (or “truthfulness claims,” as it issometimes translated) are the prime example. These are claims an actor makes

Jürgen Habermas (Stanford Encyclopedia of Philosophy) http://plato.stanford.edu/entries/habermas/

17 of 40 1/22/10 6:25 PM

Page 18: A

about his or her interior subjectivity: feelings, moods, desires, beliefs, and the like.Such claims are open to rational assessment, not in discourse but by comparisonwith the actor's behavior: for example, if a son claims to care deeply about hisparents but never pays them any attention, we would have grounds for doubtingthe sincerity of his claim. Note that such insincerity might involve self-deceptionrather than deliberative lying.

Truth and rightness claims, by contrast, are susceptible to argumentativejustification in the proper sense, through what Habermas calls “strict discourses.”As he first analyzed the discourses connected with these two types of validity(1973a), they had much in common. Although the types of reasons differed—moral discourse rested primarily on need interpretations, empirical-theoreticaldiscourse on empirical inductions—in both cases, the relevant reasons should, inprinciple, be acceptable to any reasonable agent. In the case of empirical truthclaims, this process-level presupposition of consensus rests on the idea that theobjective world is the same for all; in the case of moral rightness, it rests on theidea that valid moral rules and principles hold for all persons. In both cases, theappropriate audience for the testing of claims is universal, and in making a truth orrightness claim one counterfactually presupposes that a universal consensus wouldresult, were the participants able to pursue a sufficiently inclusive and reasonablediscourse for a sufficient length of time. Although his early statements aresomewhat unclear, on one reading Habermas defined not only moral rightness butalso empirical truth in terms of such ideal consensus (similar to C. S. Peirce). Henow further distinguishes truth from moral rightness by defining the latter, but notthe former, in terms of idealized consensus. More on that below.

Authenticity claims, unlike truth and rightness claims, do not come with such astrong consensual expectation. Habermas associates this type of claim with“ethical” discourse. Unlike moral discourse, in which participants strive to justifynorms and courses of action that accord due concern and respect for persons ingeneral, ethical discourses focus on questions of the good life, either for a givenindividual (“ethical-existential” discourse) or for a particular group or polity(“ethical-political” discourse). Consequently, the kind of reasons that constitutecogent arguments in ethical discourse depend on the life histories, traditions, andparticular values of those whose good is at issue. This reference to individual- andgroup-related particularities means that one should not expect those reasons to winuniversal consensus (1993, 1–18; 1996b, 162–68). However, Habermas (2003b)seems to recognize one class of ethical questions that do admit of universalconsensus. Choices of technologies that bear on the future of human nature, suchas genetic enhancement engineering, pose species-wide ethical issues. Such issuesconcern not merely our self-understanding as members of this or that particular

culture or tradition, but how we should understand our basic human dignity. Thecore of human dignity, and thus the basis for a human-species ethics, on his view,lies in the capacity of human beings for autonomous self-determination.

In sum, Habermas's discourse theory aligns different types of validity claim withdifferent types of justificatory discourse. At the logical level, cogent argumentsmust employ somewhat different sorts of reasons to justify different types ofclaims. Although some sorts of reasons might enter into each type of discourse(e.g., empirical claims), the set of relevant considerations that are individuallynecessary and jointly sufficient for making logically strong arguments will differ.Thus, claims about what human beings need are relevant reasons in moralarguments about welfare obligations, but not for supporting the truth claim thatquarks exist. At the dialectical level, one must meet different burdens of proof byanswering different types of challenges. For example, in defending the ethicalauthenticity of Tom's pursuit of a career in medicine, one need not show thatmedicine is a career everyone must follow, but only that such a career makessense, given Tom's personal background, talents, and desires. One can alsoexamine Tom's career choice from a moral perspective, but in that case one needonly show that anyone in his circumstances is morally permitted to pursuemedicine. At the rhetorical level, finally, the scope and depth of agreement differsaccording to the type of claim. Moral rightness claims and empirical truth claimsare justified by reasons that should be acceptable to a universal audience, whereasethical claims are addressed to those who share a particular history and tradition ofvalues.

Having differentiated types of discourse, Habermas must say something about howthey interrelate. Clearly, some discourses depend on other types: most obviously,moral and ethical discourses partly depend on empirical claims, and thus dependon the outcome of empirical discourses about the circumstances and consequencesof behavioral rules and the collective pursuit of the good life. The question ofinterrelationship becomes especially urgent in the political sphere, where differentdiscourses intertwine and lead to competing conclusions, or when issues arise inwhich discourse types cannot be cleanly separated, so that the standards ofcogency become obscure or deeply contested (McCarthy 1991, chap. 7; 1998).Because Habermas (1996c, 1534f) rejects the idea of a metadiscourse that sorts outthese boundary issues, he must answer this challenge in his democratic theory.Before taking up that topic, Habermas's theory of truth deserves a closer look.

3.3 Habermas's Theory of Truth and Knowledge

In his various essays on empirical truth, Habermas usually regards propositions as

19 of 40 1/22/10 6:25 PM

Page 20: A

the truth-bearer: in making an assertion, “I am claiming that the proposition[Aussage] that I am asserting is true” (1971/2001, 86; cf. 2003a, 249ff). In hisearly treatment, however, he immediately equated empirical truth with idealjustifiability—the consensus theory of truth mentioned above. According to thattheory, the “truth condition of propositions is the potential assent of all others”;thus “the universal-pragmatic meaning of truth…is determined by the demand ofreaching a rational consensus” (1971/2001, 89; cf. 86). Such formulations suggestthat Habermas equated the meaning of truth with the outcome of a universal,rational consensus, which he understood in reference to the ideal speech situation(ibid., 97–98). However, he soon saw the difficulties with consensus theory, and henever allowed “Wahrheitstheorien” (1973a), his main essay on the consensustheory of truth, to appear in English. Like the “epistemic” theories of truth thatlink truth with ideal warranted assertibility (e.g., Hilary Putnam, Crispin Wright),consensus theory downplays the justification-transcendent character of truth(2003a, 250–52).

Habermas now proposes instead a “pragmatic epistemological realism” (2003a, 7;1998b, chap. 8). His theory of truth is realist in holding that the objective world,rather than ideal consensus, is the truth-maker. If a proposition (or sentence,statement) for which we claim truth is indeed true, it is so because it accuratelyrefers to existing objects, or accurately represents actual states of affairs—albeitobjects and states of affairs about which we can state facts only under descriptionsthat depend on our linguistic resources. The inescapability of language dictates thepragmatic epistemological character of his realism. Specifically, Habermaseschews the attempt to explicate the relationship between proposition and worldmetaphysically (e.g., as in correspondence theories). Rather, he explicates themeaning of accurate representation pragmatically, in terms of its implications foreveryday practice and discourse. Insofar as we take propositional contents asunproblematically true in our daily practical engagement with reality, we actconfidently on the basis of well-corroborated beliefs about objects in the world.What Habermas (1971/2001, 94; TCA 1: 23) calls “theoretico-empirical” or“theoretical” discourse becomes necessary when beliefs lose their unproblematicstatus as the result of practical difficulties, or when novel circumstances posequestions about the natural world. Such cases call for an empirical inquiry inwhich truth claims about the world are submitted to critical testing. AlthoughHabermas tends to sharply separate action and discourse, it seems more plausibleto regard such critical testing as combining discourse with experimentalactions—as we see in scientific inquiry, which combines empirical arguments withpractical actions, that is, field observations and laboratory experimentation.

To date Habermas has not drawn out the implications of his discourse theory for a

Page 21: A

detailed account of truth-oriented discourses, which we find most highlydeveloped in the sciences. As an argumentation theory, such an account wouldprobably have to take the following broad lines: at the logical level, the discursivejustification of problematic truth claims heavily relies on empirical reasons:observation reports, results of experimental tests, and the like. Similarly for thedialectical level: the chief challenges arise from theories and observations thatseemingly conflict with the claim at issue or with its supporting reasons. At therhetorical level, one seeks the agreement of a potentially universal audience, giventhat truth claims are about an objective world that is the same for all humanbeings. This sketch, however, leaves out precisely the details that would make adiscourse theory of science interesting. For example, how do epistemic andaesthetic values (scope, accuracy, simplicity, etc.) affect the logical construction ofscientific arguments? Must not the presupposition of a universal audience beattenuated, given that scientists investigate aspects of the world (e.g., subatomicparticles) that are inaccessible to all but a small group of trained experts? Howdoes the cogency of scientific arguments depend on or involve various institutionalstructures and mechanisms, such as peer review, assignment of credit, distributionof grant money, and so on?

3.4 Habermas's Discourse Theory of Morality, Politics, and Law

Habermas's two enduring interests in political theory and rationality come togetherin his discourse theory of deliberative democracy. There we see him struggling toshow how his highly idealized, multi-dimensional discourse theory has realinstitutional purchase in complex, modern societies. In that context, argumentationappears in the form of public discussion and debate over practical questions thatconfront political bodies. The challenge, then, is to show how an idealized modelof practical discourse connects with real institutional contexts of decision-making.

Habermas summarizes his idealized conception of practical discourse in the“discourse principle” (D), which we might state as follows: A rule of action orchoice is justified, and thus valid, only if all those affected by the rule or choicecould accept it in a reasonable discourse. Although he first understood (D) as aprinciple of moral discourse, he now positions it as an overarching principle ofimpartial justification that holds for all types of practical discourse (cf. 1990a, 66,93; 1996b, 107). As such, it simply summarizes his argumentation theory for anyquestion involving the various “employments of practical reason” (1993, chap. 1).(D) thus applies not only to moral rightness and ethical authenticity, but also to thejustification of technical-pragmatic claims about the choice of effective means forachieving a given end. Each type of practical discourse then involves a furtherspecification of (D) for the content at issue. In developing his democratic theory,

Jürgen Habermas (Stanford Encyclopedia of Philosophy) http://plato.stanford.edu/entries/habermas/

21 of 40 1/22/10 6:25 PM

Page 22: A

Habermas has been especially concerned with two such specifications: moraldiscourse and legal-political discourse. In distinguishing these two types ofdiscourse, Habermas tackles the traditional problem of the relationship betweenlaw and morality. He also shows how to bring high-level discursive idealizationsdown to institutional earth. We start with his account of moral discourse.

Habermas's discourse ethics. Habermas's discourse theory of morality generallygoes by the name “discourse ethics,” a somewhat misleading label given that“ethics” has a distinct non-moral sense for him, as noted above. The idea of adiscourse ethics was anticipated by G. H. Mead (1962, 379–89) and has beenpursued by a number of philosophers (e.g., Karl-Otto Apel, Seyla Benhabib).Habermas's version is heavily indebted to the Kantian tradition. Like Kant, heconsiders morality a matter of unconditional moral obligations: the prohibitions,positive obligations, and permissions that regulate interaction among persons. Thetask of moral theory is to reconstruct the unconditional force of such obligations asimpartial dictates of practical reason that hold for any similarly situated agent.Also like Kant, Habermas links morality with respect for autonomous agency: infollowing the dictates of impartial reason, one follows one's own conscience andshows respect for other such agents. Unlike Kant, however, Habermas takes adialogical approach to practical reason, as his discourse theory requires. Kantassumed that in principle each mature, reflective individual, guided by theCategorical Imperative, could reach the same conclusions about what dutyrequires. This assumption has long been recognized as problematic, but inpluralistic and multicultural settings it becomes entirely untenable: one mayplausibly claim to take an impartial moral point of view only by engaging in realdiscourse with all those affected by the issue in question.

Habermas's (D)-Principle articulates this dialogical requirement. If one assumesthis requirement, then one can arrive at Habermas's specific conception ofreasonable moral discourse by working out the implications of his argumentationtheory for the discursive testing of unconditional moral obligations. What one gets,according to Habermas, is a dialogical principle of universalization (U): “A [moralnorm] is valid just in case the foreseeable consequences and side-effects of itsgeneral observance for the interests and value-orientations of each individualcould be jointly accepted by all concerned without coercion” (i.e., in a sufficientlyreasonable discourse) (1998a, 42; trans. amended). The (U)-Principle assumes thatvalid moral rules or norms allow for an egalitarian community of autonomousagents—as Kant (1785, Ak. 433; also 431) put it, a “systematic union of differentrational beings” governed by “common laws.” From the standpoint ofargumentation theory, (U) seems to state the burden of proof that structures anadequate process and procedure of justification.

Jürgen Habermas (Stanford Encyclopedia of Philosophy) http://plato.stanford.edu/entries/habermas/

22 of 40 1/22/10 6:25 PM

Page 23: A

The (U)-Principle has been a site of controversy among discourse theorists, andnot everyone considers it necessary for a discourse ethics (Benhabib and Dallmayr1990; Wellmer 1991; Gottschalk-Mazouz 2000). Habermas has argued that (U)can be deduced from statements articulating the pragmatic implications ofargumentative discourse over moral norms (1990a, 86–93; 1998a, 39–45). Moreprecisely, a successful deduction probably depends on three assumptions: (D), astatement of the semantics of unconditional norms, and an articulation of thepragmatics of discourse. If we accept (D) and if we accept Habermas's explicationof the rhetorical presuppositions of the discursive justification required by (D),then (U) would have to follow as an implication of what is required fordiscursively justifying norms with the specific content of moral norms, namelyobligations that bind persons in general and whose acceptance thus affects eachperson's pursuit of interests and the good life.

Whether or not the argument for (U) goes through, Habermas's discourse ethicsdepends on some very strong assumptions about the capacity of persons for moraldialogue. Given that his discourse theory in general, and thus (U) in particular,rests on counterfactual idealizations, one might be tempted to regard (U) as ahypothetical thought experiment, analogous to what we find in other neo-Kantianor contractualist theories like those of John Rawls and T. M. Scanlon. To someextent this is correct: to regard a moral norm as valid, one must presume it wouldhold up in a fully inclusive and reasonable discourse. But Habermas takes a furtherstep, insisting that (U) is a principle of real discourse: an individual's moraljudgment counts as fully reasonable only if it issues from participation in actualdiscourse with all those affected. Moreover, (U) requires not simply that one seekthe input of others in forming one's conscience, but that one gain their reasonableagreement.

To bring such strong idealizations down to earth, one must connect them withconscientious judgment in everyday moral practice. One way to do this is throughan account of the appropriate application of moral rules in concrete circumstances.Following Günther 1993, Habermas (1993, 35–39) acknowledges the need forsuch an account. In moral discourses of application, one must test alternativenormative interpretations of the particular situation for their acceptability beforethe limited audience of those immediately involved, on the assumption that one isapplying valid general norms. But even at the level of application, discoursecannot always include all the affected parties (e.g., when the issue concerns thefate of a comatose patient). Habermas's discourse ethics thus implies that formany, if not most, of our moral rules and choices, the best we can achieve arepartial justifications: arguments that are not conclusively convincing for all, butalso are not conclusively defeated, in limited discourses with interlocutors we

regard as reasonable (cf. Rehg 2003, 2004).

Habermas (1990a, 116–94) has also attempted to give discourse ethics someempirical foothold by looking to moral psychology and social anthropology. Thepsychological line of argument draws on the theory of communicative action toreconstruct theories of moral development such as Lawrence Kohlberg's.According to Habermas, moral maturation involves the growing ability to integratethe interpersonal perspectives given with the system of personal pronouns; theendpoint of that process coincides with the capacity to engage in the mutualperspective-taking required by (U). The anthropological line of argument focuseson identity formation, drawing on the social psychology of G. H. Mead. In broadagreement with Hegelian models of mutual recognition, Mead understands theindividual's development of a stable personal identity as inextricably bound upwith processes of socialization that depend on participation in relationships ofmutual recognition. Habermas (ibid., 195–215; 1990b) extends this analysis torespond to feminist and communitarian criticisms of impartialist, justice-basedmoralities. According to the standard critiques, such moralities assume animplausibly atomistic view of the self and thus fail to appreciate the moral importof particularity and cultural substance: particular relationships between uniqueindividuals, on the one hand, and membership in particular cultural communitiesor traditions, on the other. Mead's analysis shows that the critics are on to animportant point: if individuation depends on socialization, then anyanthropologically viable system of morality must protect not only the integrity ofindividuals but also the web of relationships and cultural forms of life on whichindividuals depend for their moral development. Discourse ethics, Habermasclaims, meets this two-fold demand in virtue of the kind of mutual perspective-taking it requires. If we examine (U), we see that it requires participants to attendto the values and interests of each person as a unique individual; conversely, eachindividual conditions her judgment about the moral import of her values andinterests on what all participants can freely accept. Consequently, moral discourseis structured in a way that links moral validity with solidaristic concern for boththe concrete individual and the morally formative communities on which heridentity depends.

These arguments are certainly ambitious, and they raise as many questions as theyanswer. It is hardly surprising, then, that many commentators have not beenpersuaded by discourse ethics as a normative ethics. Rather, they regard it asplausible only in the context of democratic politics, or as a model for the criticalevaluation of formal dialogues (e.g., environmental conflict resolution, medicalethics committees, and the like). Other critics have targeted discourse ethics at ametaethical level. In fact, Habermas first unveiled his moral theory in answer to

moral non-cognitivism and skepticism (1990a, 43–115). In this context, (U)explicates a moral epistemology: what it means for moral statements to count asjustified. If moral statements are justifiable, then they have a cognitive character inthe sense that they are correct or not depending on how they fare in reasonablediscourse. However, Habermas proposes (U) not merely as articulating aconsensus model of moral justification, but as an explication of the meaning ofrightness itself. Unlike truth, the rightness of a moral norm does not consist inreference to an independently existing realm of objects, but rather in theworthiness of the norm for intersubjective recognition. Thus rightness, unliketruth, means ideal warranted assertibility (2005b, 93; 2003a, chap. 6). However,discourse theorists remain divided over the proper understanding of idealizedconsensus and its relation to rightness.

Habermas's discourse theory of law and politics. The central task of Habermas'sdemocratic theory is to provide a normative account of legitimate law. Hisdeliberative democratic model rests on what is perhaps the most complexargument in his philosophical corpus, found in his Between Facts and Norms(1996b; German ed., 1992b; for commentary, see Baynes 1995; Rosenfeld andArato 1998; vom Schomberg and Baynes 2004). Boiled down to its essentials,however, the argument links his discourse theory with an analysis of the demandsinherent on modern legal systems, which Habermas understands in light of thehistory of Western modernization. The analysis thus begins with a functionalexplanation of the need for positive law in modern societies. This analysis picksup on points he made in TCA (see sec. 3.1 above).

Societies are stable over the long run only if their members generally perceivethem as legitimate: as organized in accordance with what is true, right, and good.In premodern Europe, legitimacy was grounded in a shared religious worldviewthat penetrated all spheres of life. As modernization engendered religiouspluralism and functional differentiation (autonomous market economies,bureaucratic administrations, unconstrained scientific research), the potentials formisunderstanding and conflict about the good and the right increased—just as theshared background resources for the consensual resolution of such conflictsdecreased. When we consider this dynamic simply from the standpoint of the(D)-principle, the prospects for legitimacy in modern societies appear quite dim.

Sociologically, then, one can understand modern law as a functional solution to theconflict potentials inherent in modernization. By opening up legally definedspheres of individual freedom, modern law reduces the burden of questions thatrequire general (society-wide) discursive consensus. Within these legalboundaries, individuals are free to pursue their interests and happiness as they see

fit, normally through various modes of association, whether that pursuit isprimarily governed by modes of strategic action (as in economic markets), byrecognized authority or consensual discourse (e.g., within religious communities,in the sciences), or by bureaucratic rationality (as in hierarchically organizedvoluntary enterprises). Consequently, modern law is fundamentally concerned withthe definition, protection, and resolution of conflicts among, individual freedomsin their various institutional and organizational contexts.

The demands on the legitimation of law change with this functional realignment:to be legitimate, modern law must secure the private autonomy of those subject toit. The legal guarantee of private autonomy in turn presupposes an establishedlegal code and a legally defined status of equal citizenship in terms of actionablebasic rights that secure a space for individual freedom. However, such rights areexpressions of freedom only if citizens can also understand themselves as theauthors of the laws that interpret their rights—that is, only if the laws that protectprivate autonomy also issue from citizens' exercise of public autonomy aslawmakers acting through elected representatives. Thus, the rights that defineindividual freedom must also include rights of political participation. As Habermasunderstands the relation between private and public autonomy, each is“co-original” or “equiprimordial,” conceptually presupposing the other in thesense that each can be fully realized only if the other is fully realized. The exerciseof public autonomy in its full sense presupposes participants who understandthemselves as individually free (privately autonomous), which in turn presupposesthat they can shape their individual freedoms through the exercise of publicautonomy. This equiprimordial relationship, Habermas (1998a, chap. 9) believes,enables his discourse theory to combine the best insights of the civic republicanand classical liberal traditions of democracy, which found expression in Rousseauand Locke, respectively.

Habermas (1996b, chap. 3) understands these rights of liberty and politicalparticipation as an abstract system of basic rights generated by reflection on thenature of discursive legitimation (articulated in the D-Principle) in contexts shapedby the functional demands on modern law (or the “form” of positive law). Becausethese rights are abstract, each polity must further interpret and flesh them out forits particular historical circumstances, perhaps supplementing them with furtherwelfare and environmental rights. In any case, the system of rights constitutes aminimum set of normative institutional conditions for any legitimate modernpolitical order. The system of rights, in other words, articulates the normativeframework for constitutional democracies, within which further institutionalmechanisms such as legislatures and other branches of government must operate.

The idea of public autonomy means that the legitimacy of ordinary legislationmust ultimately be traceable to robust processes of public discourse that influenceformal decisionmaking in legislative bodies. Habermas summarizes thisrequirement in his democratic principle of legitimacy: “only those statutes mayclaim legitimacy that can meet with the assent of all citizens in a discursiveprocess of legislation that in turn has been legally constituted” (1996b, 110). As hegoes on to explain, this principle articulates the core requirement for “externally”institutionalizing the different types of practical discourse that are relevant for thejustification of particular laws. Decisions about laws typically involve acombination of validity claims: not only truth claims about the likelyconsequences of different legal options, but also claims about their moral rightness(or justice), claims about the authenticity of different options in light of the polity'sshared values and history, and pragmatic claims about which option is feasible ormore efficient. Legitimate laws must pass the different types of discursive teststhat come with each of these validity claims. Habermas also recognizes that manyissues involve conflicts among particular interests that cannot be reconciled bydiscursive agreement on validity but only through fair bargaining processes.

This strong orientation toward cognitive validity qualifies Habermas's version ofdeliberative democracy as an “epistemic” theory. This puts his democraticprinciple in a rather puzzling position. On the one hand, it represents aspecification of the discourse principle for a particular kind of discourse (legal-political discourse). This makes it analogous to the moral principle (U), whichspecifies (D) for moral discourse. As a specific principle of reasonable discourse,the democratic principle seems to have the character of an idealizingpresupposition insofar as it presumes the possibility of consensual decisionmakingin politics. For Habermas, reasonable political discourse must at least begin withthe supposition that legal questions admit in principle of single right answers(1996c, 1491–95), or at least a set of discursively valid answers on which a faircompromise, acceptable to all parties, is possible. This highly cognitive,consensualist presumption has drawn fire even from sympathetic commentators(Bohman 1996; McCarthy 1998).

On the other hand, the democratic principle lies at a different level from principleslike (U), as Habermas himself emphasizes (1996b, 110). The latter specify (D) fora single type of practical discourse, in view of internal cognitive demands onjustification, whereas the former pulls together all the forms of practical discourseand sets forth conditions on their external institutionalization. From thisperspective, the democratic principle acts as a bridge that links the cognitiveaspects of political discourse (as a combination of the different types of idealizeddiscourse) with the demands of institutional realization in complex societies. As

such, the democratic principle should refer not to consensus, but rather tosomething like a warranted presumption of reasonableness. In fact, in a number ofplaces Habermas describes democratic legitimacy in just such terms, which wemight paraphrase as follows: citizens may regard their laws as legitimate insofar asthe democratic process, as it is institutionally organized and conducted, warrantsthe presumption that outcomes are reasonable products of a sufficiently inclusivedeliberative process of opinion- and will-formation (2005b, 107-08). Thepresumption of reasonable outcomes thus rests not so much on the individualcapacities of citizens to act like the participants of ideal discourse, but rather onthe aggregate reasonableness of a “subjectless communication” that emerges as thecollective result of discursive structures—the formal and informal modes oforganizing discussion (1996b, 184–86, 301, 341). This means that democracy is“decentered,” no longer fully under control of its own conditions and no longerbased on a congruent subject of self-legislating discourse.

In light of the above ambiguity in the status of (D), however, one might want totake a more pragmatic approach to democratic deliberation. Such an approach(e.g., Bohman 1996; McCarthy 1998) understands deliberation as less a matter ofsettling disputes over the cognitive validity of competing proposals than a matterof developing legal frameworks within which citizens can continue to cooperatedespite disagreements about what is right or good.

3.5 Habermas's Cosmopolitanism

Habermas's discourse theory also has implications for international modes ofdeliberation—hence for the debate about a potential cosmopolitan political order.To understand his position in this debate, it helps to sketch a typology of the maintheories. The current discussion moves along four main axes: political or social,institutional or noninstitutional, democratic or nondemocratic, and transnational orcosmopolitan. Theories are informed by background assumptions about the scopeof cosmopolitanism: whether it is moral to the extent that it is concerned withindividuals and their life opportunities, social to the extent that it makesassociations and institutions central, or political to the extent that it focuses onspecifically legal and political institutions, including citizenship. Habermas'sposition in this debate is moderate. It is not minimal in the sense of Rawls's law ofpeoples, which denies the need for any strong international legal or political order,much less a democratic one. Nor is it a strongly democratic position, such asDavid Held's version of cosmopolitan order. However, both Held and Habermasshare a common emphasis on the emergence of international public law as centralto a just global political order.

In his essay “Kant's Idea of Perpetual Peace: At Two Hundred Years' HistoricalRemove” (1998a, chap. 7; German ed., 1996a, chap. 7), Habermas was optimisticabout the prospects for a global political order as the continuation of the form ofdemocracy based on human rights typical of nation states. Democracy on thenation-state model connects three central ideas: that the proper politicalcommunity is a bounded one; that it possesses ultimate political authority; and thatthis authority enables political autonomy, so that the members of the demos mayfreely choose the conditions of their own association and legislate for themselves.The normative core of this conception of democracy lies in the conception offreedom articulated in the third condition: that the subject of legal constraints isfree precisely in being the author of the laws. Earlier we introduced Habermas'sargument for “decentering” democracy under the conditions of pluralism andcomplexity. If this applies to the modern state, then it would seem thatcosmopolitan democracy would take this trend even further. Yet, when discussing“postnational” legitimacy, Habermas clearly makes self-determination by asingular demos the fundamental normative core of the democratic ideal.

For Held (1995), cosmopolitan democracy is clearly continuous with democracy,at least in form, as it is realized within states. Not only does Held show howinternational society is already thickly institutionalized well beyond the systems ofnegotiation that Habermas makes central, he further recognizes that “individualsincreasingly have complex and multilayered identities, corresponding to theglobalization of economic forces and the reconfiguration of political power.” Suchpotentially overlapping identities provide the basis for participation in global civilsociety, in nongovernmental organizations (NGOs), and in other transnational civilassociations, movements, and agencies that create opportunities for politicalparticipation at the global level. Held's approach thus has three enormousadvantages: an emphasis on a variety of institutions; a multiplicity of levels andsites for common democratic activity; and a focus on the need for organizedpolitical actors in international civil society to play an important role in a systemof global democracy. For all these advantages, the self-legislating demos reappearsin Held's explicitly Lockean insistence that “the artificial person at the center ofthe modern state must be reconceived in terms of cosmopolitan public law.” Inorder to reconstitute the community as sovereign, Held argues that the demoi mustsubmit to the will of the global demos: “cosmopolitan law demands thesubordination of regional, national and local sovereignties to an overarching legalframework.”

Contrary to his earlier essay on Kant's Perpetual Peace, Habermas has now pulledback from Held's strong conception of cosmopolitanism. In The PostnationalConstellation (2001a; German ed., 1998c) and more recent essays on the European

Union, Habermas seeks to accommodate a wider institutional pluralism. Still, hecannot have it both ways. When considering various disaggregated and distributedforms of transnational political order, he describes them in nondemocratic terms,as a “negotiating system” governed by fair bargaining. This is because he clearly,and indeed surprisingly, makes self-determination through legislation the decidingcriterion of democracy. Consequently, at the transnational level, the fundamentalform of political activity is negotiation among democracies. This demos is at best acivic, rather than political, transnational order. Nonetheless, Habermas links thepossibility of a “postnational democracy” to a shared and therefore particularpolitical identity, without which, he contends, we are left with mere “moral” ratherthan “civic” solidarity. According to Habermas, even if such a political communityis based on the universal principles of a democratic constitution, “it still forms acollective identity, in the sense that it interprets and realizes these principles inlight of its own history and in the context of its own particular form of life”(2001a, 117, 107). Without a common ethical basis, institutions beyond the statemust look to a “less demanding basis of legitimacy in the organizational forms ofan international negotiation system,” the deliberative processes of which will beaccessible to various publics and to organizations in international civil society(ibid., 109).

More recently, he argues that regulatory political institutions at the global levelcould be effective only if they take on features of governance without government,even if human rights as juridical statuses must be constitutionalized in theinternational system (2004, 130–31). As in the case of Allen Buchanan'sminimalism, this less demanding standard of legitimacy does not include thecapacity to deliberate about the terms governing the political authority of thenegotiation system itself. This position is transnational, but ultimatelynondemocratic, primarily because it restricts its overly robust deliberativedemocracy to the level of the nation state. The stronger criteria for democracy arenot applied outside the nation state, where governance is only indirectlydemocratic and left to negotiations and policy networks. Furthermore, thecommitment to human rights as legal statuses pushes Habermas in the direction ofHeld's fundamentally legal form of political cosmopolitanism. At the moment,Habermas's view of cosmopolitan politics is not yet fully stable. But it is clear thathe thinks that a cosmopolitan order must be political (and not merely juridical);institutional (and not merely organized informally or by policy networks);transnational (to the extent that it would be like the European Union, an order ofpolitical and legal orders); and in some sense democratic or at least subject todemocratic norms. However, in order for him to fully adopt this last characteristicof the international system, he will have to rethink his conception of democracy as

self-legislation. If he does not do so, it seems impossible to fit democracy onto atransnational rather than fully Kantian cosmopolitan order.

4. The Dialogue between Naturalism and ReligionOn the topic of religion, Habermas has taken a nuanced position that continues todevelop. In his Theory of Communicative Action, he treated religion primarilyfrom a sociological perspective, as an archaic mode of social integration. Sincethen, however, he has explored the role of religion in politics, on the one hand, andthe relationships between religious and philosophical modes of discourse, on theother.

As a philosopher, Habermas has described his approach as a “methodologicalatheism,” by which he means a kind of experiment in radical demythologizationwhose outcome remains open. Taking this stance does not make him hostile ordismissive of faith and theological reflection; indeed, he grants that “indispensablepotentials for meaning are preserved in religious language”—potentials that, atleast so far, have not been fully reduced to philosophical and secular reasons(2002, 77, 162). At the same time, Habermas insists on the difference betweentheological and philosophical modes of discourse: as a reflection on faith, theologymust not renounce its basis in religious experience and ritual. Consequently, heresists apologetic attempts to generate religious belief from philosophicalpremises. Rather, philosophers must satisfy themselves with the “transcendencefrom within” given with the context-transcending force of claims to truth andmoral rightness.

Habermas has further developed his views on the relation between philosophy andfaith in his dialogue with Cardinal Ratzinger (who would become Pope BenedictXVI)(2006b; German ed., 2005a). There he notes how much Western philosophyowes to its Christian heritage, which philosophers assimilated by developing ideasof “responsibility, autonomy and justification; history and remembering; newbeginning, innovation, and return; alienation, internalization, and incarnation;individuality and community” (2006b, 44; trans. amended). The Christian idea ofhuman beings as created in the image of God has been especially important forWestern moral-political theory, which translated the religious idea into the secularview of persons as equal in dignity and deserving unconditional respect (ibid., 45).This assimilation of Christian ideas does not gut their substance, however. In fact,religious communities still harbor potentials of meaning from which philosophycan learn—potentials that have “been lost elsewhere and that cannot be restored bythe professional knowledge of experts alone” (ibid., 43). As examples, he refers tothe “differentiated possibilities of expression” and “sensitivities” regarding “lives

that have gone astray, societal pathologies, the failure of individual life projects,and the deformation of misbegotten human relationships” (ibid., trans. amended).In acknowledging that religious modes of expression can harbor an integralcognitive content that is not exhausted by secular translations, Habermas seems tohave located the boundaries of his methodological experiment indemythologization. He thus calls for a dialogue in which secular and religiousforms of thought mutually inform and learn from each other.

This broad point on the relation between religious and secular modes of thoughtflows directly into the position Habermas takes in his “Religion in the PublicSphere“ regarding the relation between religion and public reasons (2006a;German ed., 2005b, chap. 5). At the center of contention are the duties of believingcitizens to translate their religiously based claims into secular, publicly accessiblereasons. Habermas stakes out his position between John Rawls and Robert Audi,on the one side, and Paul Weithmann and Nicholas Wolterstorff, on the other.

Audi places the heaviest burden on believers, requiring them to support only thoselaws for which they have sufficient public reasons; each citizen thus has a duty totranslate religiously based arguments into secular ones. In his final statement onthis issue, Rawls (1997) presents a “wide view” of public reason, according towhich citizens may introduce reasons from reasonable comprehensive doctrines(which can include religious views), without translation, at any time into publicdiscourse about constitutional essentials, provided that at some point in the futurethese reasons are translated into generally accessible public arguments. ForHabermas, Audi and Rawls underestimate the existential force of religiousbelief—how such belief can, at least for some believers, provide the only sufficientbasis for their political views, even when public reasons might also be taken assupporting the views in question. The demand that believers translate theircomprehensive religious views into secular justifications imposes undue burdenson believers of this sort. The demand for translation, rather, pertains only topoliticians and public officials with institutional power to make, apply, and executethe law.

As Habermas reads them, Weithmann and Wolterstorff take the opposite line fromRawls and Audi, opening up public discourse to untranslated religious arguments.Weithmann requires believers to argue for their positions as good for everyone, buthe allows them to frame such arguments within their religiously based conceptionof justice. Wolterstorff removes even this mild constraint. Both thinkers do notimpose any institutional filter: not only in the public sphere but also in the halls ofpower, religious reasons can suffice to justify coercive legal and administrativedecisions. This move, Habermas maintains, undoes the neutrality principle that

Jürgen Habermas (Stanford Encyclopedia of Philosophy) http://plato.stanford.edu/entries/habermas/

32 of 40 1/22/10 6:25 PM

Page 33: A

undergirds modern constitutional democracy, with its separation of church andstate: the idea that “all enforceable political decisions must be formulated in alanguage that is equally accessible to all citizens, and it must be possible to justifythem in this language as well” (2006a, 12). Indeed, Wolterstorff seems to reject akey idea behind democratic legitimation, namely the presumption that proceduresand decisions should operate within a background framework of principlesacceptable to all citizens. Consequently, it is unclear how a democracy shouldmaintain its legitimacy and avoid devolving into an endless strife of factionssimply vying for power.

In the background of these debates lay contention over the burdens of citizenship.Believers might object that Habermas still places an asymmetric burden on them.After all, they must eventually, at the institutional level, shift over to secularmodes of justification, whereas non-believers need not carry out the same kind ofmove toward religious justification. In response, Habermas has offered thehypothesis that both believers and non-believers are involved in a complementarylearning process in which each side can learn from the other. As a cooperativelearning process, translation makes demands on both sides: the believer must seekpublicly accessible arguments, whereas the non-believer must approach religion asa potential source of meaning, as harboring truths about human existence that arerelevant for all.

In closing, we suggest three possible extensions to Habermas's reply to believers.First, one might note that in the West at least, Christians are not so burdened asone might think. After all, some of the most important secular ideas that informconstitutional democracy—ideas of inalienable individual rights, liberty, and thelike—partly originated in Christianity. Second, one might point out that a reverseduty of translation on non-believers would involve a far heavier burden than thaton believers, particularly in light of the first point. This is because some religiousreasons, though they might have a surface intelligibility as propositions tonon-believers, cannot be adequately appreciated or weighed apart from prolongedexperience of living the faith. Although it remains important for non-believers tolearn from believers, one should probably expect believers to have an epistemicadvantage in the translation process, that is, the process of determining whether ornot a given secular content adequately renders a religiously based reason. So ifbelievers have the greater burden, then that makes sense: believers are actually in abetter position to make the translation.

One might object that the second point presupposes an asymmetry between publicsecular reasons, to which both sides have access in principle, and religiousreasons, to which only believers have initial and direct access. However, that

Page 34: A

objection supports Habermas's position, and so leads into the third extension of hisview. The objection calls into question the assumption that everyone should inprinciple have equal access to secular reason. Once we question that assumption, itis unclear why secular reasons should have a privileged place in politicaldiscourse. However, to reject the public position of secular reasons, at least in apluralistic polity, is to say there is no public reason. Rather, each citizen'sperspective, religious or not, is comprehensive and somewhat opaque to others. Inthat case, however, every citizen now faces burdens of translation that she canshoulder only with the interlocutor's assistance. So the believer is not relieved oftranslation. Instead, everyone is now burdened by translation. To be sure, onemight also remove the asymmetry between access to secular and religious reasonby making each sort of discourse equally accessible to all in principle. But thatview hardly does justice to the existential import of religious experience, and soshould be rejected by believers.
