Across the democratic West, politics has become deeply polarised and profoundly personal. Challenge someone's political views and increasingly you challenge their very being. And yet, do our political tribes even make sense? Look carefully, and on the most important ethical issues of the age - assisted dying, social welfare, sexual liberation, abortion, gun control, the environment, technology, justice - the instinctive positions of both the Left and the Right are riven with contradictions. In this refreshing and eye-opening book, James Mumford, a public thinker and independent commentator, questions the basic assumptions of our political groups.
