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.
