This book explores controversies surrounding free speech and open inquiry (FSOI) in various regions of the Anglophone world. The authors argue that the past decade has seen a noticeable erosion of FSOI across the globe, aided and abetted by university clerisies and state apparatuses. These groups’ policing of language and pandering to cancel culture, the authors argue, have narrowed the Overton window to the point of reinvigorating the push for blasphemy law within liberal democracies themselves and impeding certain avenues scientific research. While most books on the subject discuss the American constitutional context of the First Amendment, this book considers free speech in the wider context of other Anglo countries. It also includes scholars from a variety of disciplines whose approaches will not only be ideologically distinct, but demonstrate a diversity of disciplinary approaches and concerns.
