We are increasingly accustomed to think of mankind as divided between warring creeds, separated from one another by chasms of incomprehension. In Cosmopolitanism Kwame Anthony Appiah, one of the world’s leading philosophers, challenges us to redraw these imaginary boundaries.Reviving the ancient philosophy of Cosmopolitanism as a means of understanding the complex world of today, Appiah argues we concentrate too much on what makes us different rather than recognizing our common humanity. Cosmopolitanism confronts our preconceptions about Us and Them and aims to change the way we think. It is a moral manifesto for a planet of strangers.
