Introduction to Political Theory relates political ideas to political realities through effective use of examples and case studies making theory lively, contentious and relevant. This updated third edition comes with significant revisions which reflect the latest questions facing political theory, such as the French burqa controversy, ethnic nationalism and the value of research from sociobiology. Accompanying these debates is a wealth of new and thought-provoking case studies for discussion, including (consensual) sadomasochism, affirmative action and same-sex marriage. A new chapter on difference has also been added to complement those on feminism and multiculturalism. The revised glossary, revamped website for further reading and new streamlined layout make Introduction to Political Theory third edition the perfect accompaniment to undergraduate study.
