One day a girl college student in Canada asked me to define reality for her, for a paper she was writing for her philosophy class. She wanted a one-sentence answer. I thought about it and finally said, “Reality is that which, when you stop believing in it, doesn’t go away.” That’s all I could come up with. That was back in 1972. Since then I haven’t been able to define reality any more lucidly.

But the problem is a real one, not a mere intellectual game. Because today we live in a society in which spurious realities are manufactured by the media, by governments, by big corporations, by religious groups, political groupsâ??and the electronic hardware exists by which to deliver these pseudo-worlds right into the heads of the reader, the viewer, the listener. Sometimes when I watch my eleven-year-old daughter watch TV, I wonder what she is being taught. The problem of miscuing; consider that. A TV program produced for adults is viewed by a small child. Half of what is said and done in the TV drama is probably misunderstood by the child. Maybe it’s all misunderstood. And the thing is, Just how authentic is the information anyhow, even if the child correctly understood it? What is the relationship between the average TV situation comedy to reality? What about the cop shows? Cars are continually swerving out of control, crashing, and catching fire. The police are always good and they always win. Do not ignore that point: The police always win. What a lesson that is. You should not fight authority, and even if you do, you will lose. The message here is, Be passive. Andâ??cooperate. If Officer Baretta asks you for information, give it to him, because Officer Beratta is a good man and to be trusted. He loves you, and you should love him.

So I ask, in my writing, What is real? Because unceasingly we are bombarded with pseudo-realities manufactured by very sophisticated people using very sophisticated electronic mechanisms. I do not distrust their motives; I distrust their power. They have a lot of it. And it is an astonishing power: that of creating whole universes, universes of the mind. I ought to know. I do the same thing. It is my job to create universes, as the basis of one novel after another.
