While the idea of freedom of speech may be closely associated with the American constitutional tradition under the First Amendment today, its origins go back thousands of years, and its ideals have been expressed in civilizations around the world. Joining president and CEO Jeffrey Rosen to discuss that storied history—from Martin Luther’s posting his 95 Theses, to state laws regarding social media—and examine defenses of free speech are Jacob Mchangama, author of Free Speech: A History from Socrates to Social Media, and David Cole, National Legal Director of the ACLU.
