In this witty and mischievous book, philosopher Peter Cave dissects the most controversial disputes today and uses philosophical argument to reveal that many issues are less straightforward than we'd like to believe. Leaving no sacred cow standing, Cave uses ingenious stories and examples to challenge our most strongly held assumptions. Is democracy inherently a good thing? What is the basis of so-called human rights? Is discrimination always bad? Are we morally obliged to accept refugees? In an age of identity politics and so-called 'fake news', this book is an essential resource for reinvigorating genuine public debate - and an entertaining challenge to accepted wisdom.
