Book excerpt: In The Moral and Political Philosophy of Immigration: Liberty, Security, and Equality, José Jorge Mendoza argues that the difficulty with resolving the issue of immigration is primarily a conflict over competing moral and political principles and is thereby, at its core, a problem of philosophy. Establishing the necessity of situating the public debate on immigration at the center of philosophical debates on liberty, security, and equality, this book brings into dialog various contemporary philosophical texts that deal with immigration to provide some normative guidance to future immigration policy and reform. As a groundbreaking work in social and political philosophy, it will be of great value not only to students and scholars in these fields, but also those working in social science, public policy, justice studies, and global studies programs whose work intersects with issues of immigration.
