Why should we be tolerant? What does it mean to ‘live and let live’? What ought to be tolerated and what not?Catriona Mc Kinnon presents a comprehensive, yet accessible introduction to toleration in her new book. Divided into two parts, the first clearly introduces and assesses the major theoretical accounts of toleration, examining it in light of challenges from scepticism, value pluralism and reasonableness. The second part applies the theories of toleration to contemporary debates such as female circumcision, French Headscarves, artistic freedom, pornography and censorship, and holocaust denial. Drawing on the work of philosophers, such as Locke, Mill and Rawls, whose theories are central to toleration, the book provides a solid theoretical base to those who value toleration, whilst considering the challenges toleration faces in practice. It is the ideal starting point for those coming to the topic for the first time, as well as anyone interested in the challenges facing toleration today.
