Thinking in Action is a major new series that takes philosophy to the public. Each book in the series is written by a major international philosopher or thinker, engages with an important contemporary topic and is clearly and accessibly written. The series informs and sharpens debate on topics as wide ranging as the internet, religion, the problems of immigration, and the way we think about science. Short, stimulating and provocative, Thinking in Action is an indispensable series of books for anyone who wants to think seriously about major issues confronting us today.Michael Dummett is one of the most influential philosophers of the postwar period. On Immigration and Refugees draws together his thoughts on this major issue for the first time. He shows how arguments used in support of curtailing immigration, such as perceived threats to the national culture, the swelling of local population levels, or that it is good for race relations, are often completely ungrounded.
