Cosmopolitanism is the idea that all human beings are members of a single community. Its adherents are known as cosmopolitan or cosmopolite. Cosmopolitanism is both prescriptive and aspirational, believing humans can and should be "world citizens" in a "universal community". The idea encompasses different dimensions and avenues of community, such as promoting universal moral standards, establishing global political structures, or developing a platform for mutual cultural expression and tolerance.

For example, Kwame Anthony Appiah articulates a cosmopolitan community where individuals from varying locations (physical, economic, etc.) enter relationships of mutual respect despite their differing beliefs (religious, political, etc.). In a looser but related sense, "cosmopolitan" is also used to describe places where people of various ethnic, cultural and/or religious backgrounds live together and interact with each other.

Etymology The word derives from the , or kosmopolitês, formed from "", kosmos, i.e. "world", "universe", or "cosmos", and , "politês", i.e. "citizen" or "[one] of a city". Contemporary usage defines the term as "citizen of the world".

Definitions Definitions of cosmopolitanism usually begin with the Greek etymology of "citizen of the world". However, as Appiah points out, "world" in the original sense meant "cosmos" or "universe", not earth or globe as current use assumes.Kwame Anthony Appiah, Cosmopolitanism: Ethics in a World of Strangers, W.W. Norton, New York, 2006, p. xiv

Kleingeld and Brown distinguish between moral, political, cultural and economic forms of cosmopolitanism. In the United States, two forms of cosmopolitanism have been established. For one, there is a political cosmopolitan nationalism that has defined and constructed other races. On the other hand, ethno-cultural cosmopolitanism that celebrates multiculturalism has benefited from an upswing in the United States after World War II. A definition of cosmopolitanism that handles this issue is given in a recent (2014) book on political globalization: Cosmopolitanism can be defined as a global politics that, firstly, projects a sociality of common political engagement among all human beings across the globe, and, secondly, suggests that this sociality should be either ethically or organizationally privileged over other forms of sociality.

Philosophical roots

Cosmopolitanism can be traced back to Diogenes of Sinope (E), one of the founders of Cynicism in Ancient Greece. It was said that when Diogenes was "Asked where he came from, he answered: 'I am a citizen of the world (kosmopolitês)'".Diogenes Laërtius, The Lives of Eminent Philosophers, Book VI, passage 63; online text in Greek and in English at the Perseus Project. At the time, the broadest basis of social identity among Greeks was either the individual city-state or the culturally and linguistically homogeneous Hellenic group.

Stoicism, another Greek school of thought that was founded roughly a century later, built upon Diogenes' idea, with many of its thinkers and adherents stressing that each human being "dwells [...] in two communities – the local community of our birth, and the community of human argument and aspiration".Nussbaum, Martha C. (1997). Kant and Stoic Cosmopolitanism, in The Journal of Political Philosophy Volume 5, Nr 1, pp. 1–25 A common way to understand Stoic cosmopolitanism is through Hierocles' circle model of identity, which states that individuals should regard themselves as concentric circles: the first one around the self, followed by immediate family, extended family, local group, citizens, countrymen, humanity. Within these circles human beings feel a sense of "affinity" or "endearment" towards others, which the Stoics termed Oikeiôsis. The task of world citizens becomes then to "draw the circles somehow towards the centre, making all human beings more like our fellow city dwellers, and so forth".

The ancient Chinese philosopher Mozi in preserved scripts said that "universal love and mutual benefit" could be attained "to regard other people's countries as one's own". The Chinese term tianxia (all under Heaven), a metonym for empire, has also been re-interpreted in the modern age as a conception of cosmopolitanism, and was used by 1930s modernists as the title of a Shanghai-based, English-language journal of world arts and letters T'ien Hsia Monthly.

Modern cosmopolitan thinkers In his 1795 essay "Perpetual Peace: A Philosophical Sketch", Immanuel Kant stages a ius cosmopoliticum (cosmopolitan law/right) as a guiding principle to help global society achieve permanent, enduring peace. Kant's cosmopolitan right (Weltbürgerrecht, or "world-citizen right") stems from an understanding of all human beings as equal members of a universal community. Cosmopolitan right thus works in tandem with international political rights, and the shared, universal right of humanity.

Kant's cosmopolitan right is fundamentally bound to the conditions of universal hospitality and the right of resort. Universal hospitality is defined as the right to be welcomed upon arrival in foreign territory, but is contingent on a guest arriving in a peaceful manner. Kant makes the additional claim that all human beings have the basic right of resort: the right to present oneself in a foreign land. The right of resort is derived from Kant's understanding of the Earth's surface as essentially communal, and further emphasizing his claims on equally shared universal rights among all human beings.

The philosophical concepts of Emmanuel Levinas, on ethics, and Jacques Derrida, on hospitality, provide a theoretical framework for the relationships between people in their everyday lives and apart from any form of written laws or codes. For Levinas, the foundation of ethics consists in the obligation to respond to the Other. In Being for the Other, he writes that there is no "universal moral law," only the sense of responsibility (goodness, mercy, charity) that the Other, in a state of vulnerability, calls forth. The proximity of the Other is an important part of Levinas's concept: the face of the Other is what compels the response.

For Derrida, the foundation of ethics is hospitality, the readiness and the inclination to welcome the Other into one's home. Ethics, he claims, is hospitality. Pure, unconditional hospitality is a desire that underscores the conditional hospitality necessary in our relationships with others. Levinas's and Derrida's theories of ethics and hospitality hold out the possibility of an acceptance of the Other as different but of equal standing. Isolation is not a feasible alternative in the world, therefore, it is important to consider how best to approach these interactions, and to determine what is at stake for ourselves and the others: what conditions of hospitality to impose, and whether or not we have responded to the call of the Other. Further, both theories reveal the importance of considering how best to interact with the Other and others, and what is at stake.

Derrida in an interview with Bennington (1997) summarized "cosmopolitanism",

A further state of cosmopolitanism occurred after the Second World War. As a reaction to the Holocaust and other atrocities, the concept of crimes against humanity became a generally accepted category in international law. This clearly shows the appearance and acceptance of a notion of individual responsibility that is considered to exist toward all of humankind.Beck, Ulrich (2006). The Cosmopolitan Vision, Cambridge: Polity Press, p. 45

Philosophical cosmopolitans are moral universalists: they believe that all humans, and not merely compatriots or fellow-citizens, come under the same moral standards. The boundaries between nations, states, cultures or societies are therefore morally irrelevant. A widely cited example of a contemporary cosmopolitan is Kwame Anthony Appiah.Appiah, Kwame Anthony (2006), Cosmopolitanism. Ethics in a World of Strangers, London: Penguin Books

Some philosophers and scholars argue that the objective and subjective conditions arising in today's unique historical moment, an emerging planetary phase of civilization, creates a latent potential for the emergence of a cosmopolitan identity as global citizens and possible formation of a global citizens movement.GTI Paper Series see Dawn of the Cosmopolitan: The Hope of a Global Citizens Movement, paper #15, and Global Politics and Institutions, paper #3 These emerging objective and subjective conditions in the planetary phase include improved and affordable telecommunications; space travel and the first images of our fragile planet floating in the vastness of space; the emergence of global warming and other ecological threats to our collective existence; new global institutions such as the United Nations, World Trade Organization, or International Criminal Court; the rise of transnational corporations and integration of markets often termed economic globalization; the emergence of global NGOs and transnational social movements, such as the World Social Forum; and so on. Globalization, a more common term, typically refers more narrowly to the economic and trade relations and misses the broader cultural, social, political, environmental, demographic, values and knowledge transitions taking place.

Contemporary cosmopolitan thinkers Thich Nhat Hanh discusses what he calls "Interbeing" as a way of living one's life in relation to others; "Interbeing" might easily be compared to cosmopolitanism. Nhat Hanh's philosophical beliefs are grounded in the precepts of Buddhist teachings, which involve compassion and understanding to protect and live in harmony with all people, animals, plants, and minerals. He further describes what he calls "Mindfulness Training of the Order of Interbeing" as being aware of sufferings created by, but not limited to, the following causes: fanaticism and intolerances that disrupt compassion and living in harmony with others; indoctrination of narrow-minded beliefs; imposition of views; anger; and miscommunication. Understanding and compassion for others seems to be achieved by the understanding of others' suffering and the root causes of suffering. Therefore, to be responsible is to recognize and understand suffering, which then leads to compassion. It is through this process that others can be recognized as people.

Other theorists, philosophers, and activists contend that recognizing suffering is necessary to end violence. In Scared Sacred, Velcrow Ripper takes a journey to different sites of great suffering that ultimately leads him toward developing compassion. In "The Planet", Paul Gilroy explores how the construction and naturalization of race and the hierarchies produced by difference shape the hatred of others. It is the deconstruction of these ideologies that can lead to the compassion and humanization of others. Thus individual responsibility is being aware of what Judith Butler calls the precariousness of life in self and other; being a cosmopolitan seems to be, above all, a social, ethical enterprise.

In Cosmopolitanism: Ethics in a World of Strangers, Kwame Anthony Appiah notes how social ethics seem to operate: Whatever obligation one might have to another, especially a foreign other, that obligation does not supersede the obligations one has to those people most familiar to them. However, as Judith Butler questions, "at what cost do I establish the familiar as the criterion" for valuing others? If one values the familiar more than the foreign, what are the consequences? Paul Gilroy offers a possible alternative to this emphasis on familiarity arguing that "methodical cultivation of a degree of estrangement from one's own culture and history ... might qualify as essential to a cosmopolitan commitment." This estrangement entails a "process of exposure to otherness" in order to foster "the irreducible value of diversity within sameness."
