Some excerpts from a speech by Philip K. Dick in 1978. I can’t decide if he’s extremely insightful or completely crazy.
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.
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. Or at least that is what my editors hope. However, I will reveal a secret to you: I like to build universes which do fall apart. I like to see them come unglued, and I like to see how the characters in the novels cope with this problem. I have a secret love of chaos. There should be more of it. Do not believe—and I am dead serious when I say this—do not assume that order and stability are always good, in a society or in a universe. The old, the ossified, must always give way to new life and the birth of new things. Before the new things can be born the old must perish. This is a dangerous realization, because it tells us that we must eventually part with much of what is familiar to us. And that hurts. But that is part of the script of life.
I watch the children watching TV and at first I am afraid of what they are being taught, and then I realize, They can’t be corrupted or destroyed. They watch, they listen, they understand, and, then, where and when it is necessary, they reject. There is something enormously powerful in a child’s ability to withstand the fraudulent. A child has the clearest eye, the steadiest hand. The hucksters, the promoters, are appealing for the allegiance of these small people in vain. True, the cereal companies may be able to market huge quantities of junk breakfasts; the hamburger and hot dog chains may sell endless numbers of unreal fast-food items to the children, but the deep heart beats firmly, unreached and unreasoned with. A child of today can detect a lie quicker than the wisest adult of two decades ago. When I want to know what is true, I ask my children. They do not ask me; I turn to them.
