Immigration poses some of the major moral, economic, and political challenges of the twenty-first century. Questions of the state’s responsibilities toward immigrants, open borders, security, coping with the displacement of people caused by climate change and natural disasters, and deciding who has a ‘right to remain’ are but some of the significant issues currently faced by governments, policymakers, and humanitarian organizations. The Routledge Handbook of the Ethics of Immigration is an outstanding reference source to this vitally important topic. Comprising twenty-five chapters by an international team of philosophers, economists, political scientists, and legal theorists, the handbook is organized into seven clear parts:Open Borders or Right to Control: Theoretical ArgumentsOpen Borders or Right to Control: Practical ApproachesCulture, Language, and InstitutionsImmigration and DiscriminationEntry, Exit, and ExploitationClimate, Refugees, and ProtectionImmigration EnforcementIn these sections a range of important issues are explored, such as immigration and cultural diversity, the economic aspects of immigration, discrimination, exploitation, definitions of refugee status, territory, citizenship, trafficking and gender. As such, The Routledge Handbook of the Ethics of Immigration will be of great interest to those studying philosophy, politics, economics, and related subjects such as law, sociology, and social policy.
