In a book that can be read from either end, two leading thinkers present alternative answers to one of the most difficult and divisive questions of our times

Suzanne Nossel, CEO of PEN America, argues that alongside the necessary and long-overdue elevation of minority voices in recent years, there has also arisen an uncompromising intolerance – most notably on university campuses and online – that wrongly equates a wide range of offensive speech with violence and seeks to shut it down. This has led to an escalating free speech arms race, from which everyone loses.

Charlotte Lydia Riley, historian of empire and editor of The Free Speech Wars, argues that accusations of cancel culture and defences of free speech are too often disingenuous attempts to fuel a culture war and so inhibit an important realignment in which hateful speech is at last being called out for what it is and the right to free expression is being extended to more people than ever before.
