EIGHT YEARS AGO in this magazine, I wrote about the "First Internet War": the Church of Scientology's use of copyright as a weapon against online critics who were circulating copyrighted material belonging to the church. (See "New World War," April 1996.) The case, I suggested, raised a series of "difficult and important legal issues that courts are likely to be struggling with for some time": How can copyright law, designed for the world of atoms, "take account of the strange features of this new informational landscape" in the world of bits?

Since then the questions have only become more difficult and more important, what with Napster, the recording industry's campaign against file sharing, the Digital Millennium Copyright Act, e-books, open-source software, open-access journals, TiVo, the Grey Album, and so on. Copyright law and copyright problems have gone mainstream; now everyone is thinking about copyright, and everyone--save perhaps for the most hidebound record company executive, or maybe former Motion Picture Association of America head Jack Valenti--recognizes that the technology is ushering us into a new kind of copyright space. But what does that space look like? What should it look like?

Enter Lawrence Lessig, who has transformed himself from a relatively obscure Stanford law professor toiling away in the academic vineyards into one of the best-known public intellectuals on the planet. Whenever talk turns to intellectual property and cyberspace, it seems, Lessig's name is invoked.

In Free Culture, his third and best book, Lessig shows his hand. He has a cause, and he wants us to rally to it. The cause is the protection of that imaginary piece of real estate known as "the public domain" and the "free culture" that has always, Lessig argues, been built upon and interleaved with it--the culture of transformative art, of sharing and borrowing and reborrowing and retransforming, of collages, cover versions, dramatizations, fictionalizations, and adaptations--the whole universe of ways new art builds upon and emerges from old.

It must be said that law professors usually do not make good rabble-rousers. Good rabble-rousers must engage the public's emotions. Law professors serve the goddess of reason alone, and she is a jealous mistress. Our arguments are too esoteric, our prose is too dense, we are too fond of abstraction and of argument for argument's sake, to rally people to fight under a common banner. The hyperrational discourse of the law school classroom and law journals is not, generally speaking, good training for populists.

Of course, bad rabble-rousers also engage people's emotions; when it strays too far from reasoned argument, rabble-rousing becomes demagoguery. It's a notoriously difficult line to walk, but when it is done well--judged on the terms not of the academician's debate but of the public's--it is honorable work. And in Free Culture, Lessig does it well.

Lessig succeeds in showing that...
