Cosmopolitanism refers to the ideology that all human beings belong to a single community, based on a shared morality. A cosmopolitan community might be based on an inclusive morality, a shared economic relationship, or a political structure that encompasses different nations. The argument that all citizens of the world possess an equal moral status can be interpreted as a statement that all humans deserve to be given equal respect, or that their interests deserve to be treated equally. Cosmopolitanism was initially thought to have been established by the Cynics (classical cosmopolitanism), then further interpreted and elucidated by the Stoics, and later polished and cultivated by the Enlightenment scholars (enlightenment cosmopolitanism). Cosmopolitanism is an analytical viewpoint that defends the concept of global citizenship. Global citizenship is most commonly associated with a “way of creating a personal identity,” along with various ideas about one’s moral responsibilities and political rights. It is also worth noting how within the domain of international ethics, cosmopolitanism is currently being presented as a stand-alone paradigm, apart from rival approaches including nationalism, social libreralism, and realism. However, the difficulty of distinguishing cosmopolitanism from these rivals becomes apparent, and there are those who think that such discerning lines create more confusion than clarity about the various disagreements within the field.

Deontological international ethics describes, analyzes, and assesses the principles governing the interactions of actors at and across various levels of society; focuses on the relations between states and other international actors; and is concerned with identifying and specifying the moral duties that each kind of international actor bears toward all others. The core theoretical elements of deontological international ethics include accounts of individual and collective agency, moral reason, the moral nature of action, and respect for the moral law as a necessary feature of ethical action. There are three historical phases of deontological international ethics: divine command and natural law ethics prior to Kant, late-modern thinker Immanuel Kant’s international ethics, and contemporary neo-Kantian approaches to nuclear ethics and transnational economic relations. The divine command ethical theories posit divine authority as the absolute and incontrovertible source of moral obligation. Meanwhile, natural law focuses on the intrinsically moral nature of military action and the centrality of moral agency and intention in the rightful use of force. On the other hand, Kant’s systemic deontological ethical theory posits individuals and states as autonomous and rational moral agents, identifies the categorical imperative as the supreme rational principle or morality and the concept of public right as its political corollary, describes a formal method for actors to determine their moral duty in ideal and non-ideal contexts, and applies this theory to the problems of interstate conflict and commerce.

The concepts of ethics, justice, and security are inextricably linked within the field of International Relations (IR). In IR, three concepts are most often deployed in understanding the ethics of security: norms, rules, and laws. These norms, rules, and laws evaluate security, which is an alternative concept for describing what IR as a discipline has long sought to address: namely, war. Hence, norms, rules, and laws provide a means to evaluate violence and war. Using the first three concepts to evaluate the latter two is the heart of ethics and security. The concept of justice, however, suggests that simple norms, rules, and laws may not be enough. There have been debates about the use of military force since ancient times—the Judeo-Christian, Greco-Roman, and Islamic traditions have their own conceptions of how war and violence ought to be addressed. One of the more prominent ideas drawn from these debates is the concept of the “just war,” which emerged from Christian tradition. The concept of just war has played a role in constructing the international legal tradition. This tradition as an explicit moral one was subsumed into international law during the nineteenth century, but re-emerged in the mid-twentieth century. Today, it has become an influential source of critical reflection upon both legal and practical dilemmas in international security, informing a wide range of debates around the world.

The proliferation of international peacebuilding practice in the 2000s was accompanied by a series of questions that has produced a significant body of writing about peacebuilding ethics within International Relations. This growing body of literature has produced questions, debates and theoretical positions. As explored below, a limited set of meta-ethics considerations provide the foundation for normative theorizing, particularly the moral objectivist commitment to positive peace. The majority of theorizing is situated among normative ethics debates. These works respond to the questions: Who has agency or who ought to have agency in peacebuilding? What ends should peacebuilding pursue? And, what means will ensure that peacebuilding is done right? The related literature focuses on a broad range of conditions, from individuals working for nongovernmental organizations to state- and United Nations–sponsored interventions. It includes authors who write from cosmopolitan, consequentialist, postcolonial, virtue, critical, feminist, and Foucaultian perspectives, among others. Finally, there is nascent work in descriptive and applied ethics.
Peacebuilding efforts to rebuild relationships and structures during and after conflict, violence and war present a series of ethical questions and challenges for international and national actors. Should the international community engage in peacebuilding? To what extent? Who ought to be involved? What constitutes good ends for peacebuilding? How can peacebuilding be done right? These questions identify the ways in which peacebuilding has been morally interrogated since its rise in prominence as a form of international intervention in the 1990s. The history of peacebuilding and peacebuilding meta-ethics must be considered with a view toward current normative ethics debates involving agency as well as the ends and means in peacebuilding.
The just war tradition is the most dominant framework for analyzing the morality of war. Just war theory is being challenged by proponents of two philosophical views: realism, which considers moral questions about war to be irrelevant, and pacifism, which rejects the idea that war can ever be moral. Realism and pacifism offer a useful starting point for thinking about the ethics of war and peace. Feminists have been engaged with the just war tradition, mainly by exposing the gendered biases of just war attempts to restrain and regulate war and studying the role that war and its regulation plays in defining masculinity. In particular, feminists claim that the two rules of just war, jus ad bellum and jus in bello, discriminate against women. In regard to contemporary warfare, such as post-Cold War humanitarian interventions and the War on Terror, feminists have questioned the appropriateness of just war concepts to deal with the specific ethical challenges that these conflicts produce. Instead of abstract moral reasoning, which they critique as being linked to the masculine ideals of autonomy and rationality, many feminist argue for certain varieties of an ethics of care. Further research is needed to elaborate the basis of an ethical response to violence that builds on philosophical work on feminist ethics. Key areas for future investigation include asking hard questions about whom we may kill, and how certain people become killable in war while others remain protected.

The social contract tradition derives its ethical force from the hypothetical agreement that parties would reach in an initial choice situation. This initial choice situation brings together a description of the circumstances of justice, various extra-contractarian moral assumptions, and an instrumental theory of rational choice. The circumstances of justice refer to the conditions that require principles of justice. These conditions include the existence of social cooperation along with moderate scarcity. In the absence of such conditions, principles of justice are either unnecessary or impossible to sustain. Social cooperation generates both benefits and burdens, and it is the allocation of those components of social cooperation that requires principles of justice. The application of the social contract to the domestic context dates back to the ancient Greeks, though their version of the contract was somewhat crude and rather one-sided in favor of state authority. Later versions of the social contract would oblige the state to provide much more to citizens in return for their allegiance. John Rawls is widely credited with resurrecting the social contract tradition in the twentieth century. His thought holds special significance for the international social contract, as he extends the contractual approach ethics into the international system where his predecessors declined to do so.
Virtue Ethics (VE) is a way of thinking about how to behave well which focuses on the character of moral agents and the nature of the good life. This contrasts with dominant approaches to international ethics which prioritize the identification or development of moral rules or duties (deontological approaches) or the consequences of actions (consequentialist approaches). The relevance of virtue ethics to international affairs is established by setting out the critique of the dominant law-based approaches offered by VE and then exploring the positive contribution VE can make. Virtue ethicists argue that character and a concrete conception of the human good are central to ethics—that the right question to ask when working out what it means to be ethical is not “what should I do” but “what sort of person should I be?” The three central concepts in VE—virtue, practical wisdom, and flourishing—have not been applied systematically qua VE in international political theory or international relations, but their appearance in various guises in recent scholarship suggests avenues for future research. Four such avenues are identified, ranging from the moderate to the radical, which offer innovative ways to confront key ethical dilemmas faced in international affairs.
