"Freedom of expression has a history. It is neither coeval with Christianity, as Catholic apologists sometimes assume, nor inherently valuable, as commentators in the United States often contend. On the contrary, it emerged in its modern form only in the seventeenth century as a byproduct of generations of horrific warfare between Catholics and Protestants. For John Locke, freedom of expression took the form of an appeal for religious toleration; in the Enlightenment, this appeal would become transmogrified into a principled defense of pluralism as a civic ideal. Innovations in the means of communications have often been disruptive. Yet the challenge posed by digital media is unusually stark. A new age calls for a new vision. The value of free expression is enhanced, and not diminished, if it is localized in time and space. Liberty is the ally, and not the antagonist, of political regulation and social control. What the sacred cause of liberty demands is not more free expression, but better free expression, and in the pursuit of this elusive yet essential goal, there is much to be done." (Conclusion)
