Cosmopolitanism: Ethics in a World of Strangers

Kwame Anthony Appiah

Liberal cosmopolitanism

A graceful, humane case for cosmopolitanism — the idea that we have obligations to all human beings, not only to our own, and that we can value our differences while still living together. Appiah steers between a rootless universalism and a closed tribalism, arguing for conversation across cultures as the way strangers come to understand and tolerate one another. A vital contemporary, global-minded counterweight to resurgent nationalism and to relativism alike.

About the author

British-Ghanaian philosopher (b. 1954), professor at New York University and a leading thinker on identity, race, and ethics. Raised between England and Ghana, Appiah writes on cosmopolitanism, the ethics of identity, and moral revolutions for both scholarly and popular audiences, and is known to many as the New York Times Magazine's 'The Ethicist.'

Synopsis

Appiah develops cosmopolitanism as two intertwined ideas: that we have obligations beyond kin and citizenship, and that we take a real interest in the practices and beliefs of others. Through stories and argument, he defends moral judgment across cultures against relativism while resisting the fantasy of total agreement, proposing conversation — getting used to one another — as the practical art of living together in a world of difference.

Core passage idea

Paraphrase · Modern copyrighted work

Appiah argues for a cosmopolitanism that holds two ideals together: that we have obligations to strangers beyond our own community, and that we should take seriously the value of lives and practices other than our own.

By pairing universal obligation with genuine respect for difference, Appiah charts a path between a flattening universalism and a closed nationalism. His emphasis on conversation, rather than agreement, makes cosmopolitanism a practice of coexistence rather than a demand for sameness.

To avoid a bubble

Pair with communitarians and nationalists (from MacIntyre to Yoram Hazony) who argue that real obligations and identity are local and particular, and with critics who think cosmopolitanism asks too much of ordinary loyalties or too little of global justice.

Reading note

Accessible and warm. Read it as the liberal-cosmopolitan reply to both nationalism and relativism, and pair it with communitarian and nationalist critics to test how far our obligations really extend.

Best paired with

Will Kymlicka, Multicultural Citizenship; Yoram Hazony, The Virtue of Nationalism.
