 of moral insight. It claims only to reconstruct the implicit normative orientations that guide individuals and it claims to access these through an analysis of communication.

Presupposition

Habermas maintains that normative validity cannot be understood as separate from the argumentative procedures used in everyday practice, such as those used to resolve issues concerning the legitimacy of actions and the validity of the norms governing interactions. He makes this claim by making reference to the validity dimensions attached to speech acts in communication and the implicit forms of argumentation they imply (see Universal pragmatics

). The basic idea is that the validity of a moral norm cannot be justified in the mind of an isolated individual reflecting on the world. The validity of a norm is justified only intersubjectively in processes of argumentation between individuals; in a dialectic

. The validity of a claim to normative rightness depends upon the mutual understanding achieved by individuals in argument.

 extracted moral principles from the necessities forced upon a rational subject reflecting on the world. Habermas extracts moral principles from the necessities forced upon individuals engaged in the discursive justification of validity claims, from the inescapable presuppositions of communication and argumentation. These presuppositions were the kinds of idealization that individuals had to make in order for communication and argumentation to even begin. For example:
  • The presupposition that participants in communicative exchange are using the same linguistic expressions in the same way
  • The presupposition that no relevant argument is suppressed or excluded by the participants
  • The presupposition that no force except that of the better argument is exerted
  • The presupposition that all the participants are motivated only by a concern for the better argument


There were also presuppositions unique to discourse:
  • The presupposition that everyone would agree to the universal validity of the claim thematized
  • The presupposition that everyone capable of speech and action is entitled to participate, and everyone is equally entitled to introduce new topics or express attitudes needs or desires
  • The presupposition that no validity claim is exempt in principle from critical evaluation in argumentation


These are all at the center of Habermas's moral theory. Habermas's discourse ethics attempts to distill the idealized moral point of view that accompanies a perfectly rational process of argumentation (also idealized), which would be the moral principle implied by the presuppositions listed above. The key point is that the presuppositions of argumentation and communication that have been rationally reconstructed by Habermas are both factual and normative. This can be said about his entire project because it is explicitly attempting to bridge the gap between the "is" and the "ought". Habermas speaks of the mutual recognition and exchanging of roles and perspectives that are demanded by the very structural condition of rational argumentation. He maintains that what is implied in these factual presuppositions of communication is the deep structure of moral norms, the conditions that every valid norm must fulfill.

Universalization

The presuppositions of communication express a universal obligation to maintain impartial judgment in discourse, which constrains all affected to adopt the perspectives of all others in the exchange of reasons. From this Habermas extracts the following principle of universalization (U), which is the condition every valid norm has to fulfill:

(U) All affected can accept the consequences and the side effects that [the norm's] general observance can be anticipated to have for the satisfaction of everyone's interests, and the consequences are preferred to those of known alternative possibilities for regulation. (Habermas, 1991:65)


This can be understood as the deep structure of all acceptable moral norms, and should not be confused with the principle of discourse ethics (D), which presupposes that norms exist that satisfy the conditions specified by (U).

(D) Only those norms can claim to be valid that meet (or could meet) with the approval of all affected in their capacity as participants in a practical discourse.


The implications of (U) and (D) are quite profound. (U) claims to be a rational reconstruction of the impartial moral point of view at the heart of all cognitivist moral theories. According to moral cognitivists (e.g. Kant, Rawls etc.), it is only from such a moral point of view that insight into the actual (quasi-factual) impersonal obligations of a general will can be gained, because this perspective relieves decisions from the inaccuracies of personal interests. Of course, Habermas's reconstruction is different because it is intersubjective. That is, Habermas (unlike Kant

) formulates the moral point of view as it arises out of the multiple perspectives of those affected by a norm under consideration. The moral point of view explicated in (U) is not the property of an individual subject but the property of a community of interlocutors, the results of a complex dialogical process of role taking and perspective exchanging. Furthermore, (U) is deduced from a rational reconstruction of the presupposition of communication, which downgrades the strong transcendentalism of Kantian ethics by establishing a foundation in inner-worldly processes of communication.

(D) on the other hand is a principle concerning the manner in which norms conforming to (U) must be justified though discourse. Again, Habermas takes the task of moral reflection out of the isolated individual's head and gives it to intersubjective processes of communication. What (D) proposes is that moral principles must be validated in actual discourse and that those to be affected by a norm must be able to participate in argumentation concerning its validity. No number of thought experiments can replace a communicative exchange with others regarding moral norms that will affect them. Moreover, this general prescription concerning the type of discourse necessary for the justification of moral norms opens the process of moral deliberation to the kind of learning that accompanies a fallibilistic orientation. (U) and (D) are catalysts for a moral learning process, which although fallible is not relative. The flesh and blood insights of participants in communicative exchange are refracted through the universal guidelines explicated from the deep structures of communication and argumentation. This spawns discourses with a rational trajectory, which are grounded in the particular circumstances of those involved but aimed at a universal moral validity.

 rights. Drawing on the work of Habermas and Apel, Hoppe, a former student of Habermas's, asserts that argumentation, or discourse, is by its nature a conflict-free way of interacting and requires individual control of resources; thus, he argues, certain norms are presupposed as true by anyone engaging in genuine discourse. These norms include the libertarian principle of non-aggression, which itself implies libertarian rights. Therefore, no one can argumentatively deny libertarian rights without self-contradiction.

Gary B. Madison's views are similar to Hoppe's argumentation ethics and also draw on Habermasian discourse ethics. Madison argues that

the various values defended by liberalism are not arbitrary, a matter of mere personal preference, nor do they derive from some natural law. . . . Rather, they are nothing less and nothing more than what could be called the operative presuppositions or intrinsic features and demands of communicative rationality itself. In other words, they are values that are implicitly recognized and affirmed by everyone by the very fact of their engaging in communicative reason. This amounts to saying that no one can rationally deny them without at the same time denying reason, without self-contradiction, without in fact abandoning all attempts to persuade the other and to reach agreement.


These implicitly recognized values include a renunciation of the legitimacy of violence. Thus,

it is absolutely impossible for anyone who claims to be rational, which is to say human, outrightly to defend violence .... [As Paul Ricoeur
Paul Ricoeur
Paul Ricœur was a French philosopher best known for combining phenomenological description with hermeneutic interpretation...

 writes:]'. . . violence is the opposite of discourse. . . . Violence is always the interruption of discourse: discourse is always the interruption of violence.' That violence is the opposite of discourse means that it can never justify itself—and is therefore not justifiable—for only through discourse can anything be justified. As the theory of rational argumentation and discussion, liberalism amounts, therefore, to a rejection of power politics.


Thus, Madison, like Hoppe, argues that the fact-value gap can be bridged by an appeal to the nature of discourse.

While Hoppe attempts to show that the non-aggression principle (i.e., self-ownership plus the right to homestead) itself is directly implied by any discourse or argumentation, Madison's arguments are a bit different. For instance, he argues that, because discourse has priority over violence, this validates the Kantian claim that people ought to be treated as ends rather than means, which is the principle of human dignity. The principle of freedom from coercion then follows from the principle of human dignity.

The "estoppel" theory of Stephan Kinsella

 draws on Hoppe's theory. Kinsella argues that an aggressor cannot coherently object to being punished for the act of aggression, by the victim or the victim's agents or heirs, i.e. he is "estopped" from withholding consent, because by committing aggression he commits himself to the proposition that the use of force is legitimate, and therefore, his withholding consent based on his right not to be physically harmed contradicts his aggressive legitimation of force.http://www.stephankinsella.com/publications.php#rightsth

In a theory bearing some resemblance to Kinsella's estoppel theory, law professor Lawrence Crocker proposes the use of moral estoppel in preventing a criminal from asserting the unfairness of being punished in certain situations. Crocker's theory, while interesting, is not rigorous, and Crocker does not seem to realize the implications of estoppel for justifying only the libertarian conception of rights. Rather than focusing on the reciprocity between the force used in punishment and the force of an aggressive act by a wrongdoer, Crocker claims that a person who has "treated another person or the society at large in a fashion that the criminal law prohibits" is "morally estopped" from asserting that his punishment would be unfair. Crocker's theory is not quite libertarian, however, since it seems to assume that any law is valid, even those that do not prohibit the initiation of force.

Van Dun even suggests that "principles of private property and uncoerced exchange" are also presupposed by participants in discourse.

 also proposes that an argument about 'dialogue rights' which draws on themes from Hayek and Karl Popper may be developed to justify individual property rights and other classical liberal principles, in an argument different in approach from that of Hoppe, Madison, and van Dun.

Other theories bearing some resemblance to discourse ethics include the theory that the nature of discourse may be used to defend the right to free speech and Tibor Machan's view that discourse in general and political dialogue in particular rest on individualist prerequisites or presuppositions. However, Machan, accepting the validity of action-based ethical theories, but not those based purely on argumentation, also maintains that "human action needs to be understood by reference to human nature."

In addition, a "law," in normal usage, has a procedural component that, if adhered to, limits a government's arbitrary and irrational use of power which defends the procedural natural-law position. Language users implicitly accept this normative, procedural aspect of what is described as law; they use a definition of law that also limits what state power can be classified as law.

A somewhat similar argument is made by libertarian law professor and legal theorist Randy Barnett

. Barnett argues that those who claim that the U.S. Constitution justifies certain government regulation of individuals are themselves introducing normative claims into discourse, and thus cannot object, on positivist or wertfrei grounds, to a moral or normative criticism of their position.

Alan Gewirth was an American philosopher, a professor of philosophy at the University of Chicago, and author of Reason and Morality, , Human Rights: Essays on Justification and Applications , The Community of Rights , Self-Fulfillment , and numerous other writings in moral philosophy and political...

. Although he disagrees with the non-libertarian conclusions that Gewirth himself draws from his own rights theory, Pilon states that he builds "upon much of the justificatory groundwork he [Gewirth] has established, for I believe he has located, drawn together, and solved some of the most basic problems in the theory of rights."

To determine what rights we have, Pilon (following Gewirth) focuses on "what it is we necessarily claim about ourselves, if only implicitly, when we act." Pilon argues that all action is conative, that is, an agent acts voluntarily and for purposes which seem good to him. Pilon argues that the prerequisites of successful action are "voluntariness and purposiveness," the so-called "generic features" that characterize all action. Thus an agent cannot help valuing these generic features and even making a rights-claim to them. From this conclusion, it is argued that all agents also necessarily claim rights against coercion and harm. And since it would be inconsistent to maintain that one has rights for these reasons without also admitting that others have these rights too (since the reasoning concerning the nature of action applies equally to all purposive actors), such rights-claims must be universalizable. Thus, an agent in any action makes a rights-claim to be free from coercion and harm, since such rights are necessary to provide for the generic features of action, which an agent also necessarily values, and the agent also necessarily grants these rights to others because of the universalizability requirement. (Note that Hans-Hermann Hoppe

rejects Gewirth's contention that universalizability applies to action; Hoppe maintains that it applies only to argumentation: "from the correctly stated fact that in action an agent must, by necessity, presuppose the existence of certain values or goods, it does not follow that such goods then are universalizable and hence should be respected by others as the agent’s goods by right. . . . Rather, the idea of truth, or of universalizable rights or goods only emerges with argumentation as a special subclass of actions, but not with action as such, as is clearly revealed by the fact that Gewirth, too, is not engaged simply in action, but more specifically in argumentation when he wants to convince us of the necessary truth of his ethical system." Hoppe, The Economics and Ethics of Private Property, p. 316 n.18.)

From this point, Pilon/Gewirth develops a sort of modern Categorical Imperative, which is called the "Principle of Generic Consistency" (PGC). The PGC is: "Act in accord with the generic rights of your recipients as well as of yourself." ("Recipients are those who stand opposite agents, who are 'affected by' or 'recipients of' their actions.") Under Pilon's libertarian working of the PGC, the PGC does not require anyone to do anything. It is addressed to agents, but it does not require anyone to be an agent who has recipients. An individual can "do nothing" if he chooses, spending his life in idle contemplation. Provided there are no recipients of this behavior, he is at perfect liberty to perform it. And if there are recipients, the PGC requires only that he act in accord with the generic rights of those recipients, i.e., that he not coerce or harm them. Pilon extends his reasoning and works the PGC to flesh out more fully just what (primarily libertarian) rights we do have.
