Multiculturalism has recently been declared dead; at the same time, the value of diversity is still emphasised. How can we explain this? In this book, Alexej Ulbricht sets out to completely reassess liberal theories of multiculturalism, and argues that the ‘backlash’ is actually the strengthening of tendencies already present in liberal multiculturalism. Using the theories of Roberto Esposito, he argues that liberal multiculturalism is best understood as a series of immunitary processes. He examines three of these processes - using the work of Kymlicka, Parekh and Taylor - and looks to what cultural coexistence beyond immunity might be like.
