until people started believing in evolutionâthen when they did start to believe in it, you couldnât turn around without tripping over fossils.â
âYou really believe this?â I asked.
âYes, I do!â she said intensely.
âThen it must be so,â I said.
âOh, it is,â she agreed, and I knew that she really did believe it. She made a very convincing case. In fact, the more she talked, the more I began to believe it too.
âWhy did you tell me all this?â I asked.
âBecause weâre in great danger. Thatâs why.â She whispered fiercely, âThe world isnât changing uniformly. Everybody is starting to believe in different things, and theyâre forming pockets of noncausality.â
âLike a pimple?â I offered.
âYes,â she said, and I could see a small one forming on the tip of her nose. âIt works this way: a fanatic meets another fanatic, then the two of them meet with some other people who share the same hallucinations, and pretty soon there are a whole bunch of fanatics all believingthe same thingâpretty soon, their delusions become real for themâtheyâve started to contradict the known reality and replaced it with a node of nonreality.â
I nodded and concentrated on wrapping a swirl of the fog securely around me.
âThe more it changes, the more people believe in the changes, and the stronger they become. If this keeps up, we may be the only sane people left in the worldâand weâre in dangerââ
âTheyâre outnumbering our reality?â I suggested.
âWorse than thatâall of their different outlooks area starting to flaw the structure of space! Even the shape of the Earth is changing! Why, at one time, it was really flatâthe world didnât turn round until people started, to believe it was round.â
I turned round then and looked at her, but she had disappeared into the fog. All that was left was her grin.
âBut the world is really pear shaped,â I said. âI read it in Scientific American. â
âAnd why do you think itâs changing shape?â the grin asked. âItâs because a certain nation is starting to believe that itâs really bigger than it is. The Earth is bulging out to accommodate them.â
âOh,â I said.
âItâs the fault of the news mediaâtelevision is influencing our image of the world! They keep telling us that the world is changingâand more and more people keep believing it.â
âWell,â I said. âWith the shape of the world the way it is today, any change has got to be for theââ
âOh, God not you too! All you people keep talking about the world going to piecesâfalling apart at the seams.â
And then even the grin was gone.
I was left there. I was also right. Other people had begun to notice it too. Great chunks of the surface had gone blotchy, and holes had appeared in it. More and more pieces were falling out all the time, but the waters had not yet broken through from the other side.
I poked my finger through one of the holes, and I could feel the soft gelatinous surface behind. Perhaps it hadnât completely thawed out yet.
So far, nothing had been accomplished about my eyeânot only was it beginning to ache something fierce, but my I was beginning to twinge a bit also, and I had a feeling that that too might be going opaque.
âHave you found yourself yet?!â one of the speakers in the park demanded. (I hadnât even lookedâand remembering my previous experiences with looking for things, I certainly was not going to initiate any kind of a search.) I walked on.
Farther on, there was, another speakerâthis one on a soup box. âWe should be thankful for this great nation of ours,â the speaker woofed and tweetered, âwhere so many people are allowed to believe in so many different
