If the literate mind shaped the modern world, what kind of world will the post-literate mind create? The surge in literacy and the democratisation of knowledge provided by Gutenberg's printing press helped ignite the Enlightenment. 500 years later, the internet is initiating a new transformation. But critics claim that beneath the internet's triumph of access lies a crisis of thought. Reading is in free-fall, with OECD data show literacy stagnating across the developed world. Are the rise of digital media and the decline of literacy dangerous trends that threaten our politics, culture, and thought itself, or should we celebrate the internet as a new and radical extension of Gutenberg's dream of democratising the production and distribution of knowledge?
