He argues that you can be rooted in a particular place and people while remaining a citizen of the whole world — and that these are not in tension.
Appiah was born in London to a Ghanaian father and English mother, raised in Ghana, educated at Cambridge, and has spent his career between Princeton, NYU, and a dozen other institutions. His work on cosmopolitanism argues that loyalty to one's culture and loyalty to humanity as a whole are not opposites: you can be attached to what is yours without requiring it to be universal. He has written on race — arguing against racial essentialism while taking racial identity seriously — on honor and the history of moral revolutions, and on what it means to live well. He is among the rare philosophers who writes for general audiences without condescension, who treats the reader as capable of following the argument and drawing their own conclusion. His father left him a letter asking him to keep the family's connections to Ghana, which he reads as an instruction about what inheritance means: you can accept a legacy without being defined by it.

“We do not need, have never needed, to agree on everything in order to act together.”
“There is a name for what happens when people across cultures influence each other: it is called life.”
Appiah joined Princeton's philosophy department in 2002. He published Cosmopolitanism in 2006, making the case for a liberalism that values cultural difference rather than requiring its erasure. His background — raised between Ghana and England, son of a Ghanaian politician and an English writer — shaped a philosophy that took hybridity as a fact and a value.
Appiah works within and extends the Rawlsian tradition of liberal political philosophy, bringing it into conversation with identity, multiculturalism, and the ethics of belonging across cultural difference.
Appiah grew up reading Du Bois and wrote In My Father's House partly as a sustained engagement with Du Bois's philosophy of race. He challenged Du Bois's racial essentialism — the idea that there is a 'gift' specific to African peoples — while honoring the moral seriousness of his project.
Wiredu and Appiah, both shaped by Ghana and by Oxford-trained analytic philosophy, share a central concern with what it means to do philosophy from an African perspective without either romanticizing tradition or simply importing Western categories wholesale.
