A review of:

"Life on the Screen: Identity in the Age of the Internet", by Sherry Turkle , Simon and Schuster (1995), 347 pages, $25

Life on the Screen, Sherry Turkle's new book about the Internet describes this online encounter between two players in a virtual environment: A young man named Barry meets Julia, whom one critic has called a "hockey-playing ex-librarian with an attitude." Barry decides to woo Julia, attempting to talk her into entering his virtual appartment, presumably with no good in mind. One snatch of typed conversation goes like this:

Barry says, "Hello, how are you?"

Julia says, "Hello, Barry."

Barry says, "Are you a virgin?"

Julia says, "As far as you are concerned, Barry, I always will be."

Barry and Julia are conversing in a multiple-user domain, or MUD . To create a MUD, a programmer writes a basic script describing some environment - perhaps a spaceship, enchanted island, or old mansion. MUD players then sign on through the Internet, adopting any identity and characteristics they choose, building virtual rooms or spaces described in words on the screen.

The screen identity of a player may have little or no relation to his or her real self. Players often change gender, age, appearance, level of wealth, etc. In fact, as Barry eventually learns, a MUD character may have no real self at all. The bewitching Miss Julia continues to resist his advances for several days until, at last, Barry learns that he has not been wooing a real person at all.

Julia is a 'bot', a computer program written to respond reasonably in conversations. She began her existence in the mind of some programmer, but today she independently roams the halls of her MUD, virtually captivating young men.

Encounters like Barry and Julia's are at the heart of Turkle's examination of "identity in the age of the Internet," her book's subtitle. She has been exploring such matters for 20 years, most recently as a professor of sociology at the Massachusetts Institute of Technology, where she teaches about the relations between humans and computers. Her research prompts her to ask, "Is the real self the naturally occurring one? Is the real self always the one in the physical world. As more and more real business gets done in cyberspace, could the real self be the one who functions best in that world?"

These questions have important moral ramifications. What are the ethics of swapping identities? Does someone who signs onto the Internet under a different persona violate the virtues of honesty, trustworthiness, and integrity, or do the rules of the game allow such tinkering?

You might conclude that all is fair among consenting palyers. In fact such games can be seen as a way of sparking moral imagination. As Turkle puts it, "We can use [the Internet] as space for growth." By trying out new personae, we can, she argues, learn more about our real selves and the nature of artifice. Then we can return from cyberspace enlarged by our experience. "Virtuality need not be prison," she writes. "It can be the raft, the ladder, the transitional space, the moratorium, that is discarded after reaching greater freedon."

But suppose, for example, that you sign on as an aggressive male in search of what is know on MUDs as 'TinySex'; that is, simulated sex carried on through conversation. If it is true that 90% of sex is in the mind, then such an excounter might be almost as emotional as the real thing?

Now suppose that the player behind the identity you meet is a 10-year-old child. Should you enter into a highly emotional encounter with such a person?

Playing in a MUD may be entertaining, stimulating, and growth-enhancing for a healthy adult. But for an immature individual, it might also be frightening or traumatic. If there's a chance your actions might cause harm to another, are you morally obligated to refrain from playing the game?

And what if the player behind the identity you meet is, like Julia, a bot? When one player learned that Julia was just a computer program, she reported feeling "shallow, void, hollow, superficial, fake, out of control of the situation." What is the programmer's obligation to reveal the bot's identity - or lack of it?

This question becomes more critical when you realize that "talking programs" are not just games. There are, for example, programs designed to present themselves as psychoanalysts. One such early program of this type, ELIZA, is responsible for something called the ELIZA effect, which is a generally observed tendency for people to treat programs that respond to them as if the programs had more intelligence than they really do. People tend to project their own complexity onto the computer.

Some therapists have experimented with having computers do preliminary work with patients, and some patients have found the progams helpful. While the phenomenon of cyberpsychology is not in itself troubling, given the current state of the technology, it is important for therapists to be upfront about the fact that patients are consulting with a computer program.

But, as programs become more sophisticated, Turkle raises the startling possibility that they may have some measure of intelligence or personlike life. A number of decades ago, the brilliant computer scientist Alan Turing proposed a test to determine whether a computer was intelligent. He suggested that a person of average intelligence be allowed to communicate through a keyboard with an unknown in another room, asking any question the player wished. If the person could not tell that the unknown was a computer, the computer was to be called 'intelligent'. One observer suggests that it's not clear if Julia passed the Turing test or Barry failed it.

In any event, modern computer programs have come close enough to genuine intelligence for some thinkers to propose that we take them seriously as fellow creatures. Christopher Langton, who organized the first Conference on Artificial Life in 1987, believes that it is not too soon to begin considering the rights of machines that almost think.

Most people, of course, are more concerned with human rights and haw they may be affected by technology. The Internet, for example, is evolving with incredible speed and without central control, raising the specter of all sorts of abuses.

Many have responded to this pace with calls to regulte the Net for pornography, libel, racist language, and so forth. Yet it is important to note that lack of central authority is hardly unique to the Internet. We are enveloped in human systems - language, medicine, politics - that have evolved with little or no overall control. As with all parts of our fragmented lives, in the end, we have to rely on individual responsibility and integrity to guide our "life on the screen."
