As soon as you begin to ask what is ultimately real, you right away begin talk nonsense. Zeno proved that motion was impossible (actually he only imagined that he had proved this; what he lacked was what technically is called the “theory of limits”). David Hume, the greatest skeptic of them all, once remarked that after a gathering of skeptics met to proclaim the veracity of skepticism as a philosophy, all of the members of the gathering nonetheless left by the door rather than the window. I see Hume’s point. It was all just talk. The solemn philosophers weren’t taking what they said seriously. But I consider that the matter of defining what is real — that is a serious topic, even a vital topic. And in there somewhere is the other topic, the definition of the authentic human. Because the bombardment of pseudo-realities begins to produce inauthentic humans very quickly, spurious humans — as fake as the data pressing at them from all sides. My two topics are really one topic; they unite at this point. Fake realities will create fake humans. Or, fake humans will generate fake realities and then sell them to other humans, turning them, eventually, into forgeries of themselves. So we wind up with fake humans inventing fake realities and then peddling them to other fake humans. It is just a very large version of Disneyland.
It was always my hope, in writing novels and stories which asked the question “What is reality?”, to someday get an answer. This was the hope of most of my readers, too. Years passed. I wrote over thirty novels and over a hundred stories, and still I could not figure out what was real. 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 groups… . 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. And I have to build them in such a way that they do not fall apart two days later.
