The paradox confronting us today is that even as we know more and process information at a faster rate, we reason, think, and understand less. While a wealth of literature has been devoted to similar topics, the deep philosophical implications of this seismic shift have not been properly explored until now. Demonstrating that knowledge based on reason plays an essential role in society and that there is more to knowing than just acquiring information, leading philosopher Michael P. Lynch shows how the modern Internet has distorted not only the way we learn and communicate but also the very essence of what it means to be human. Charting a path from Plato’s cave to Sheldon’s mathematical theory of information to Google Glass, Lynch builds on previous works by Nicholas Carr, James Gleick, and Jaron Lanier to give us a necessary guide for how to navigate the philosophical quagmire that is the Information Age.
