Global justice constitutes a central concern in political philosophy, stemming from considerations of inequity. It is occasionally conceptualized as a manifestation of internationalism. A distinction can be drawn between global justice and international justice: the latter primarily addresses equity among nations or states, while the former prioritizes the individual human being, aiming "to articulate the principles of fairness applicable to such agents."
Global justice is an issue in political philosophy arising from the concern about unfairness. It is sometimes understood as a form of internationalism. Global justice and international justice may be distinguished in that the latter is concerned with justice between nations or states whereas the former sees individual human beings as its main concern and seeks "to give an account of what fairness among such agents involves".
History
Norwegian philosopher Henrik Syse asserts that global ethics and international justice are integral to the Western tradition of natural law. He notes that this topic has been systematically structured and disseminated within Western intellectual traditions since the era of the Middle Stoa and Cicero in Latin antiquity, extending through the contributions of early Christian philosophers such as Ambrose and Augustine. Syse elaborates:
This early natural-law theoretical framework focused on the concept of a ius naturale, specifically, a system of inherent rights universally applicable to all individuals, serving humanity as a normative standard for moral discernment.
Context
According to American political scientist Iris Marion Young, a prevalent philosophical perspective maintains that the purview of just obligations is circumscribed by affiliation with a shared political community. Under this framework, individuals bear duties of justice exclusively towards those with whom they coexist under a unified constitution or whom they acknowledge as co-nationals. English philosopher David Miller concurred, asserting that such obligations extend solely to individuals residing together or sharing national identity.
The concept of global justice endeavors to address the question of reciprocal obligations within a global framework. This involves both positive and negative duties, which can sometimes conflict with individual moral principles. Proponents of cosmopolitanism, notably including the ancient Greek philosopher Diogenes of Sinope, have characterized themselves as citizens of the world. William Godwin, a prominent utilitarian and anarchist thinker, contended that all individuals possess an impartial obligation to maximize beneficence, without preferential treatment for any specific person.
The broader political backdrop to this discourse is the enduring tension between localized institutions, exemplified by conflicts such as tribes versus states, villages versus cities, local communities versus empires, or nation-states versus the United Nations. Historically, the comparative influence of local entities relative to global ones has diminished. Between the early modern era and the twentieth century, the state emerged as the paramount political institution, characterized by its sovereignty, territoriality, asserted monopoly on the legitimate application of force within its borders, and its existence within an international system comprising other sovereign states. During this epoch, political philosophers predominantly concentrated on domestic aspects of justice, examining questions such as the appropriate treatment of subjects by states and the mutual obligations among co-citizens. Consequently, justice concerning interstate relations and cross-border individual interactions was largely relegated to a secondary concern or addressed by scholars of international relations.
Nevertheless, since the First World War, the state system has undergone significant transformation due to globalization and the establishment of supranational political and economic entities, including the League of Nations, the United Nations, and the World Bank. Concurrently, and particularly since the 1970s, global justice has gained increasing prominence within political philosophy. Within the contemporary discourse on global justice, the overarching theme of impartiality primarily revolves around the ethical implications of national borders and the concept of shared citizenship.
Central questions
Three interconnected inquiries—pertaining to the scope of justice, the equitable distribution of wealth and other resources, and the institutions tasked with upholding justice—constitute the core challenges within the domain of global justice. When these inquiries are examined under non-ideal conditions, they fall within the purview of the "ethics of process," a specialized field of political ethics.
Scope
Do objective ethical standards exist, as posited by moral universalists, that are applicable to all individuals irrespective of their culture, race, gender, religion, nationality, or other differentiating characteristics? Alternatively, are ethical norms exclusively relevant within circumscribed contexts such as specific cultures, nations, communities, or voluntary associations?
A moral conception of social justice is considered universalistic only if:
- It mandates that all individuals adhere to an identical framework of fundamental moral principles.
- These principles uniformly allocate fundamental moral benefits and burdens to all individuals.
- Crucially, these fundamental benefits and burdens are designed to avoid arbitrary privileging or disadvantaging of specific groups.
Distributive Equality
Gillian Brock critically examines the scope of global responsibility, questioning whether the focus should be on ensuring basic needs and 'decent' lives or on achieving broader global socio-economic equality. This inquiry is particularly pertinent given that 1.1 billion people—18% of humanity—live below the World Bank's $2/day poverty line. Such disparities prompt fundamental questions about the justice of wealth distribution, the root causes of poverty, and potential systemic injustices within the global economy. Diverse philosophical perspectives address these issues: John Rawls argued that international obligations primarily exist between states that meet a 'minimal condition of decency,' whereas Thomas Nagel contended that obligations to others are individual, and moral reasons for restraint are not necessary for individuals to deserve equal international treatment. Peter Singer, in 'Famine, Affluence, and Morality,' asserts that the affluent have a moral obligation to contribute their resources to those in need.
Institutions
A central question in global justice concerns which institutions—encompassing states, communes, federal entities, global financial bodies such as the World Bank, international non-governmental organizations, multinational corporations, international courts, or even a world state—are best suited to realize the ideal of global justice. Further considerations involve how these institutions might secure public support, who bears the responsibility for their establishment and maintenance, and the appropriate degree of freedom for movement across the jurisdictions of various territorial entities.
Thomas Pogge asserts that states alone are insufficient for achieving global justice, stating: "It has never been plausible that the interests of states — that is, the interests of governments — should furnish the only considerations that are morally relevant in international relations." Pogge and Moellendorf further highlight that organizations such as the World Trade Organization, despite advocating free trade, have historically permitted protectionist policies in affluent developed nations.
Public opinion polls demonstrate support for the International Criminal Court (ICC). Notably, 130 civil society groups in Africa, while acknowledging the ICC's operational inconsistencies, continue to endorse it as vital for achieving global justice. Similarly, the Extraordinary Chambers in the Courts of Cambodia (ECCC) have drawn mixed reactions; some observers contend that "the court will not truly be effective unless it can properly address the crucial issue of how reparations will be given to victims of the regime," while others, such as Youk Chhang, director of the Documentation Centre of Cambodia, have lauded it as "the most important trial in Cambodian history." Another global body, the Intergovernmental Panel on Climate Change (IPCC), responsible for climate change agreements, has been criticized for insufficient speed. Furthermore, Anne Petermann and Orin Langelle of the Global Justice Ecology Project reported that in 2007, industry insiders received preferential treatment over "civil society observers and delegates from poorer countries whose visas were delayed" during IPCC events.
Minimum Criteria
Thomas Pogge contends that an "institutional order cannot be just if it fails to meet the minimal human rights standard," a benchmark rooted in the Universal Declaration of Human Rights. In contrast, Mathias Risse argues against the presence of injustice, noting that "While indeed 1.2 billion people in 1998 lived below the poverty line of $1.08 PPP 1993 per day, it is also true that there is now less misery than ever before." Risse's standard for justice is "Less Misery," and he proclaimed in 2005 that "progress made over the last 200 years is miraculous."
Main Positions
Contributors to the global justice discourse have adopted five primary theoretical stances: realism, particularism, nationalism, the society of states tradition, and cosmopolitanism (which manifests in two distinct forms).
Realism
Realist scholars, including Charles Yeo and Hashim Tilab, contend that global ethical standards are nonexistent, asserting that their presumed existence constitutes a perilous delusion. Within an international anarchic system, states function as primary actors, invariably striving to act rationally in their own self-interest. Consequently, regarding fundamental ethical inquiries, moral universalism is deemed either fallacious or merely indicative that no state is prohibited from pursuing its interests. Obligations to assist the impoverished are absent unless such actions align with a state's strategic objectives. The state system is thus considered the foundational and immutable global institutional framework. This realist perspective traces its theoretical lineage from Machiavelli to Glaucon's challenge to Socrates. In this framework, interstate relations are characterized by what Charles Beitz terms a Hobbesian state of nature, reflecting a realist commitment to observing states "as they truly are," rather than through an idealistic lens or based on their professed ideals.
Particularism
Particularists, such as Michael Walzer and James Tully, posit that ethical standards emerge from shared meanings and practices, which are cultivated and maintained by distinct cultures or societies. Moral and social critique is feasible within the confines of such groups but not across them. For instance, in an egalitarian society, citizens may be deemed morally culpable and can legitimately criticize one another if they fail to uphold their own egalitarian principles; however, they cannot validly critique a caste-based society using those same ideals. As articulated, "A given society is just if its substantive life is lived in a certain way—that is, in a way faithful to the shared understandings of [its] members." Conversely, it is unjust if this condition is not met. Each society possesses unique standards, binding only its members, who alone can appropriately engage in self-critique. Therefore, moral universalism is rejected because objective ethical standards demonstrably vary across cultures and societies. The criteria for distributive justice applied to strangers should not be identical to those applied to compatriots. Nation-states, by embodying their peoples' shared and distinctive ethical understandings, are considered the appropriate institutions for facilitating localized and diverse forms of justice.
Charles Blattberg, however, proposes a particularist approach to global justice founded on what he terms "global patriotism."
Nationalism
Nationalists, including David Miller and Yael Tamir, argue that demanding mutual obligations are forged by a specific and valuable form of association: the nation. While humanitarian duties to assist the severely disadvantaged globally may exist, these are considerably less stringent and urgent than obligations owed to fellow citizens. Nationalism has historically incorporated this premise of differentiated moral responsibilities towards those within and outside the nation, exemplified by the fact that welfare state benefits are typically not extended to citizens of other countries. Consequently, moral universalism is considered overly simplistic, as ethical standards applicable between compatriots diverge from those relevant to strangers (though some nationalists advocate for the universal ethical standard that nations should possess their own states). Distributive justice is primarily an intranational concern, not necessarily an international one. A global system comprising nation-states is thus deemed the appropriate structure for organizing justice for all, within their distinct associational groups.
Society of states
Within the tradition of the society of states, individual states are conceptualized as entities capable of mutually agreeing upon common interests and rules of interaction, including moral precepts, much like human individuals. This concept of agreement among peers is frequently formalized through a social contract argument.
John Rawls stands as a notable proponent within this tradition. In his work, The Law of Peoples, Rawls expands the methodology established in A Theory of Justice to address the complexities of global justice. He posits that a global regime can be justified if it would be selected by representatives of various Peoples in a hypothetical original position, where their knowledge of their specific People is withheld. This decision-making process, conducted under a veil of ignorance, ensures impartiality by eliminating self-serving biases. When Rawls applied this methodology to domestic justice, with parties in the original position representing individual members of a singular society, he contended that it advocated for a redistributive, egalitarian liberal political framework. Conversely, Rawls asserts that applying his method to global justice yields a more conventional, Kantian international ethic, emphasizing state duties to uphold treaties and stringent restrictions on warfare, yet precluding global redistribution of private property. Consequently, distinct principles of justice are applicable to domestic and international contexts. While justice may necessitate egalitarianism within states, this requirement does not extend to relations between them. A global institutional structure comprising cooperating but independent states represents the just arrangement. Rawls characterizes this ideal as a 'realistic utopia'. Beyond Rawls, Hedley Bull is also recognized as a significant proponent of this viewpoint.
Cosmopolitanism
Proponents of cosmopolitanism contend that a form of moral universalism holds true, thereby asserting that all individuals, not solely compatriots or fellow citizens, are encompassed by the purview of justice. Their arguments commonly invoke principles of consistency, articulated as follows:
- The moral status of individuals derives from certain morally salient characteristics.
- These attributes are universally shared by all humans, extending beyond the confines of any particular nation, culture, society, or state.
- Consequently, all humans possess moral standing, rendering the distinctions between nations, cultures, societies, and states morally inconsequential.
Nevertheless, cosmopolitans diverge on the specific shared human characteristics that hold moral significance.
Consequentialist cosmopolitans, notably including Peter Singer, assert that the appropriate criterion for moral evaluation of actions, practices, or institutions lies in their outcomes, with the welfare of humans (or indeed, all sentient beings) serving as the metric for these consequences. Thus, the capacity for experiencing welfare and suffering constitutes the universal foundation for moral standing. This perspective implies that the severe welfare deprivations experienced by some individuals due to poverty generate a moral imperative for anyone capable of providing assistance to do so. Neither geographical separation between the affluent and the impoverished nor their differing national citizenships bears any moral significance.
Advocates for human rights within cosmopolitanism, including Thomas Pogge and Simon Caney, contend that all individuals possess fundamental rights, potentially those enumerated in the UN's Universal Declaration of Human Rights. One perspective suggests that these rights impose a positive obligation on affluent nations to ensure the provisions they guarantee (e.g., security, sustenance); alternatively, it can be argued that the wealthy are presently contravening their negative duty by perpetuating a global system that systematically infringes upon the rights of the impoverished.
Some scholars advocate for a neoconservative interventionist foreign policy, grounded in a cosmopolitan perspective, citing the potential for such interventions to enhance human rights. For instance, the 2003 invasion of Iraq was defended by some on this basis, given the extensive human rights violations perpetrated by Saddam Hussein against numerous members of the Kurdish and Shiite communities.
Cosmopolitans exhibit significant diversity in their interpretations of distributive justice and the legitimacy of global governance structures. For example, some, like Kai Nielsen, advocate for a world government, while others, such as Simon Caney, reject this notion. The degree to which cosmopolitans support the global redistribution of resources also varies. Charles Beitz, for instance, proposes addressing resource disparities by applying the Rawlsian difference principle internationally to benefit the world's most disadvantaged populations, though his focus is on natural resources rather than a broader range of societal assets, including talents. Nevertheless, a core tenet shared by all cosmopolitans is the conviction that individuals, rather than states, nations, or other collective entities, constitute the fundamental locus of universal moral principles.
Demands
None of the five principal perspectives previously outlined expresses complete contentment with the existing global order. Realists contend that states prioritizing idealistic moral objectives through intervention and humanitarian assistance, rather than safeguarding their own strategic interests, ultimately harm their populations and destabilize the international system. Particularists oppose the erosion of traditional cultures by cultural colonialism, whether it manifests as economic liberalism or the defense of human rights. Nationalists lament the prevalence of stateless individuals and populations living under ineffective or oppressive regimes. Proponents of the society of states express apprehension regarding rogue states and the imperialistic aspirations of powerful nations. Cosmopolitans assert that the contemporary global landscape falls short of their ethical benchmarks, necessitating substantial reforms in the conduct of affluent individuals and states.
