Just as the printing press led to the appearance of a new set of possibilities for democracy, beginning five hundred years ago--and just as the emergence of electronic broadcasting reshaped those possibilities, beginning in the first quarter of the twentieth century--the Internet is presenting us with new possibilities to reestablish a healthy functioning self-government, even before it rivals television for an audience. In fact, the Internet is perhaps the greatest source of hope for reestablishing an open communications environment in which the conversation of democracy can flourish. It has extremely low entry barriers for individuals. The ideas that individuals contribute are dealt with, in the main, according to the rules of a meritocracy of ideas. It is the most interactive medium in history and the one with the greatest potential for connecting individuals to one another and to a universe of knowledge. An important distinction to make is that the Internet is not just another platform for disseminating the truth. It's a platform for pursuing the truth, and the decentralized creation and distribution of ideas, in the same way that markets are a decentralized mechanism for the creation and distribution of goods and services. It's a platform, in other words, for reason. But just as it is important to avoid romanticizing the printing press and the information ecosystem it created, it is also necessary to keep a clear-eyed view of the Internet's problems and abuses. It is hard to imagine any human evil that is not somehow abundantly displayed somewhere on the Internet. Parents of young children are often horrified to learn what obscene, grotesque, and savage material is all too easily available to children whose Web-surfing habits are not supervised or electronically limited. Teen suicides, bullying, depravity, and criminal behavior of all descriptions are described and--some would argue--promoted on the Internet. As with any tool put at the disposal of humankind, it can be, and is, used for evil as well as good purposes. And as always, it is up to us--particularly those of us who live in a democracy--to make intelligent choices about how and for what we use this incredibly powerful tool.
