Cosmopolitanism is a demanding and contentious moral position. It urges us to embrace the whole world into our moral concerns and to apply the standards of impartiality and equity across boundaries of nationality, race, religion or gender. It suggests a range of virtues which the cosmopolitan individual should display: tolerance, justice, pity, righteous indignation at injustice, generosity toward the poor and starving, care for the global environment, and the willingness to take responsibility for change on a global scale. This book explains and espouses the values of cosmopolitanism, adjudicates between various forms of cosmopolitanism, and defends it against its critics. The book highlights ethical issues and identifies the moral obligations that individuals, multinational corporations and governments might have in relation to them. The book discusses the work of Kwame Anthony Appiah, Seyla Benhabib, Martha Nussbaum, Thomas Pogge, John Rawls, Amartya Sen, Henry Shue, Peter Singer and others to provide a clear and accessible survey of cosmopolitanism that analyses the reality of the rights and responsibilities that it espouses.
