Kate Wolf speaks with historian Fara Dabhoiwala about his new book, What is Free Speech? The History of a Dangerous Idea. A foundational aspect of the U.S. Constitution, free speech is a relatively recent invention and one rooted less in democratic ideals than first may be clear. Tracking its evolution from the pre-modern age through the Enlightenment to our present day, Dabhoiwala explores how free speech and freedom of the press initially served imperial and corporate interests rather than those of common citizens. His book also examines the counterintuitive ways free speech continues to be an engine for questionable ends today, benefitting tech companies and upholding misogyny and racism. But while it has never been equally distributed, free speech has also resulted, at times, in more freedom rather than less, so what are we to do with this abiding concept and how might we modify its absolutism to better serve those it claims to protect?
