Immigration is the issue of our time: riddled with moral, environmental, philosophical and political questions with few clear-cut solutions. Political philosopher Avner de-Shalit guides us through some of these complexities, with a particular focus on cities. How do cities cope with large flows of migrants and refugees? Should they have a right to stop people from settling in the city?  Which model of integration works best and where can it be found?  Avner de-Shalit is here with much needed insights on how to integrate immigrants in cities.
