Remember what makes some a moral right: if there is a moral justification for a claim, then that person has a moral right. From this definition, we see that for a person to have a moral right, all that is needed is for the person`s claim to be morally justified. Since the rigour with which the term “rights” is used does not clarify questions concerning the obligations of moral agents towards beings who are not moral agents, more needs to be said. What kind, if any, would be ethically acceptable to be used in such experiments? Is it morally relevant that the subjects are mammals? Would intelligence be morally relevant to the decision, and if so, how? Would the presence or absence of a complex social system in which members care for other members of the species be a morally relevant factor to consider? Would it be morally relevant for one candidate species to have a more human face than another? Would it be relevant that some people have ever been human pets? If so, would it be better or worse to use these people? So what are the legal obligations? These are legal requirements that legal entities must comply with. A mandatory act or omission is something that the law does not make optional. Since people can clearly violate their legal obligations, “non-optional” does not mean that they are physically forced to perform, and this law does not leave them behind without an appropriate alternative. On the contrary, people often calculate whether or not they are fulfilling their legal obligations. Could it then be that tasks are only important reasons for performance, even if they are sometimes neglected or outdated? This cannot be a sufficient condition: high courts have important reasons not to turn around too often, but no legal obligation to refrain from doing so. It is also not necessary: you have an obligation, but only a trivial reason, not to step on someone`s lawn without your consent. Members of organic associations often feel obligated to other members, but we generally look for an independent reason for them (see Simmons, 1996; Wellman, 1997).
One version emphasizes the value of obligations associated with social roles. The duty of obedience is explained by the representation of the associated social role, for example “member”, “citizen” or “subject”. It is important to see that there is not one problem here, but two. It is a fundamental question: what does the political role really require? And there is the question of validity: what makes these requirements binding on their residents? (See Hardimon 1994.) But these are closely related: you can not solve the second independently of the first. There is no general answer to the question of why role duties are related – it depends on roles and duties. Every legal system contains mandatory laws, but there is no decisive linguistic marker that determines what they are. There is no need to use the term “obligation”, nor is it almost synonymous with “duty”. You rarely find mood imperative.
Canada`s Criminal Code commits not to advocate genocide: “Anyone who advocates or promotes genocide is guilty of a criminal offence and may be punished by imprisonment for up to five years.” The English Sale of Goods Act states: “If the seller sells goods in the course of a transaction, there is an implied condition that the goods delivered under the contract are of merchantable quality.” The fact that these laws create obligations stems from the way the “crime” and the “implied condition” operate in their respective jurisdictions, not from the language in which they are expressed. The basis of Rawls` theory necessarily becomes evident when we examine how it might be a just institution to “apply to us.” A.J. Simmons convincingly argues that an institute for the advancement of philosophers cannot be beneficial to us, however just it may be, and then demands that we pay its dues (Simmons 1979, 148). It therefore suggests that a normatively relevant meaning of application requires acceptance of the benefits – but that is, it converts a natural mandatory account into a weakly voluntary account like equity. (See below, § 5.3.) Jeremy Waldron diagnoses the power of such counter-examples because the Institute, although it operates fairly, is not something whose activities are required by justice: they are optional, not necessary (Waldron 1993). This seems to be true; But if we then limit the realm of authority to necessity, we will again leave many legal obligations behind. Many of the activities of a legitimate government are optional. It must save us from the state of nature, but the ambitions of the law are broader than that. It also does things that are allowed but not necessary: enact residential areas, explain official languages, set national holidays, support education and the arts, and create honors.
And in the service of what is prescribed by necessity, the law draws lines and establishes norms that are themselves authorized only – an age of consent, an acceptable level of imposition of risks, formalities for wills and marriages, and so on – what Aquinas called “provisions” of just requirements. The content of all this valuable and permissible state action is underdetermined by the theory of legitimacy and is based on considerations other than necessity. The necessary arguments therefore leave some – perhaps a lot – valuable state actions unsubstantiated. In addition, it is not clear what is necessary for the law to perform its socially necessary functions. Anscombe refers to the right to have what is needed for the role, but what is it? Hume thought it was obvious that political society could not exist without “the exact obedience of the magistrate,” but this is certainly empiricism without the facts. Everyone knows that a legal system can and does tolerate a certain degree of harmless disobedience and that this does not affect its functioning in any way. A third account is based on reason. From this point of view, it is neither the social resources with which they are applied nor the practices in which they can be expressed, but the nature of the reasons for action they offer. Legal obligations are content-independent reasons that apply both categorically and preventively. The characteristic of their material independence is that their power does not depend on the nature or merits of the action they need: in most cases, the law may impose an obligation to make X or omit X (Hart 1958; 1982, 254-55; but cf. Markwick 2000). The fact that they are preventive means that they require the subject to set aside his own vision of the substance while complying with it.
The fact that they are categorical means that they do not link their claims to the subject`s own objectives or interests. This touches on a methodological issue in the philosophy of law. Some believe that the character of the authority of the law is a matter of descriptive analysis, defined by the semantic and logical limits of the official language and the traditions of argumentation. Others argue that such an analysis is impossible or indefinite, and that we are therefore led to normative arguments about what legal authority should be (see Soper 2002; Finnis 1979, pp. 12-15). Generally speaking, they think that we should understand the law in such a way that it only claims the kind of authority it would justify for the law. This is the motivation for Friedrich Hayek`s suggestion that “the ideal type of law […] merely provides additional information to be taken into account in the actor`s decision” (Hayek 1960, 150). Hayek advocates the free market and concludes that the nature of legal authority must be understood in a similar way.
