'Impassioned, scholarly and succinct' The Times FREE SPEECH AND WHY IT MATTERS Free speech is the bedrock of all our liberties, and yet in recent years it has come to be mistrusted. A new form of social justice activism, which perceives language as potentially violent, has prompted a national debate on where the limitations of acceptable speech should be drawn. Governments throughout Europe have enacted 'hate speech' legislation to curb the dissemination of objectionable ideas, Silicon Valley tech giants are collaborating to ensure that they control the limitations of public discourse, and campaigners in the US are calling for revisions to the First Amendment. However well-intentioned, these trends represent a threat to the freedoms that our ancestors fought and died to secure. In this incisive and fascinating book, Andrew Doyle addresses head-on the most common concerns of free speech sceptics, and offers a timely and robust defence of this most foundational of principles.
