Abstract

“Having a moral right” in private and public debates probably is one of the most important arguments to bring some foundation to one’s claims. Within international law and politics, for example, one easily falls back on universal “human rights”, especially if neither a more subtle moral argument nor prudential reasons find a hold. But in some contrast to this agreement on the strong practical relevance of rights, both the conceptual analysis and normative justification of rights are rather controversial in moral philosophy. There is, perhaps, a consensus on a constructivist understanding of rights, that is that rights have to be constructed from a basis of more “elementary parts” of morality. There is no agreement, however, on the exact character of these parts and their normative import within an overall construction of rights. It seems to be clear somehow that rights have to secure and promote interests — of a human and animal kind. Not so clear is the kind of foundation rights can be given within the sphere of interests, especially if this is understood in a reductive sense. Nevertheless, because the function of rights is to secure interests, the construction of rights from an understanding of interests seems to suggest itself. It is in the interest of all beings to have their interests secured and furthered by rights. Therefore, an “interest theory of rights” provides itself as a primary option — meaning thereby the justificatory, and not the directive side of rights
