While freedom of speech has been guaranteed us for centuries, the First Amendment as we know it today is largely a creation of the past 80 years. "Eternally Vigilant" brings together a group of distinguished legal scholars to reflect boldly on its past, its present shape, and what forms our understanding of it might take in the future. The result is a unique volume spanning the entire spectrum of First Amendment issues, from its philosophical underpinnings to specific issues like campaign regulation, obscenity and the new media.
