Permutation City

'I'm not afraid: I just want to get it over with. But . . . go ahead. Prove whatever you think you have to prove, and then we can move on.'

Squeak. 'That's the plan. But I think we could both use a break now. I'll enable your communications -- for incoming data only.' He turned away, reached off-screen, and hit a few keys on a second terminal.

Then he turned back to the camera, smiling -- and Paul knew exactly what he was going to say.

Squeak. 'By the way, I just deleted one of you. I couldn't afford to keep you both running, when all you're going to do is laze around.'

Paul smiled back at him, although something inside him was screaming. 'Which one did you terminate?'

Squeak. 'What difference does it make? I told you, they were identical. And you're still here, aren't you? Whoever you are. Whichever you were.'

Three weeks had passed outside since the day of the scan, but it didn't take Paul long to catch up with the state of the world; most of the fine details had been rendered irrelevant by subsequent events, and much of the ebb and flow had simply canceled itself out. Israel and Palestine had come close to war again, over alleged water treaty violations on both sides -- but a joint peace rally had brought more than a million people onto the glassy plain that used to be Jerusalem, and the two governments had been forced to back down. Former US President Martin Sandover was still fighting extradition to Palau, to face charges arising from his role in the bloody coup d'etat of thirty-five; the Supreme Court had finally reversed a long-standing ruling which had granted him immunity from all foreign laws, and for a day or two things had looked promising -- but then his legal team had discovered a whole new set of delaying tactics. In Canberra, another leadership challenge had come and gone, with the Prime Minister remaining undeposed. In a week-old report, one journalist described this, straight-faced, as 'high drama.' Paul thought: I guess you had to be there. Inflation had fallen by half a per-centage point; unemployment had risen by the same amount.

Paul scanned the old news reports rapidly, skimming over articles and fast-forwarding scenes which he felt sure he would have studied scrupulously, had they been fresh. He felt a curious sense of resentment, at having 'missed' so much -- it was all there in front of him, now, but that wasn't the same at all.

And yet, he wondered, shouldn't he be relieved that he hadn't wasted his time on so much ephemeral detail? The very fact that he was now less than enthralled only proved how little of it had really mattered, in the long run.

Then again, what did? People didn't inhabit geological time. People inhabited hours and days; they had to care about things on that time scale.

People.

Paul plugged into real-time TV, and watched an episode of The Unclear Family flash by in less than two minutes, the soundtrack an incomprehensible squeal. A game show. A war movie. The evening news. It was as if he was in deep space, rushing back toward the Earth through a sea of Doppler-shifted broadcasts. The image was strangely comforting; his situation wasn't so bizarre, after all, if flesh-and-blood humans could find themselves in much the same relationship with the world as he did. Nobody would claim that the Doppler shift could rob someone of their humanity.

Dusk fell over the recorded city. He ate a microwaved soya protein stew -- wondering if there was any good reason, moral or otherwise, to continue to be a vegetarian.

He listened to music until long after midnight. Tsang Chao, Michael Nyman, Philip Glass. It made no difference that each note 'really' lasted seventeen times as long as it should have, or that the audio ROM sitting in the player 'really' possessed no microstructure, or that the 'sound' itself was being fed into his model-of-a-brain by a computerized sleight-of-hand that bore no resemblance to the ordinary process of hearing. The climax of Glass's Mishima still seized him like a grappling hook through the heart.

And if the computations behind all this had been performed over millennia, by people flicking abacus beads, would he have felt exactly the same?

It was outrageous to admit it -- but the answer had to be yes.

He lay in bed, wondering: Do I still want to wake from this dream?

The question remained academic, though; he still had no choice.

(Remit not paucity)

NOVEMBER 2050

Maria had arranged to meet Aden at the Nadir, an Oxford Street nightclub where he sometimes played and often went to write. He could usually get them both in for free, and the door -- an intimidating, airlock-like contraption of ribbed black anodized steel -- let her pass unchallenged after a brief security scan. Maria had once had a nightmare in which she'd been trapped in that chamber, a knife inexplicably strapped to her right boot -- and, worse, her credit rating canceled. The thing had digested her like an insect in a Venus flytrap, while Aden stood on stage, singing one of his cut-up love songs.

Inside, the place was crowded for a Thursday night, and poorly lit as always; she finally spotted Aden sitting at a table near a side wall, listening to one of the bands and jotting down music, his face catching the glow of his notepad. So far as Maria could tell, he never seemed to be unduly influenced by anything he listened to while composing, but he claimed to be unable to work in silence, and preferred live performances for inspiration -- or catalysis, or whatever it was.

She touched him on the shoulder. He looked up, took off his headset, and stood to kiss her. He tasted of orange juice.

He gestured with the headset. 'You should listen. Crooked Buddhist Lawyers on Crack. They're quite good.'

Maria glanced at the stage, although there was no way of telling who he meant. A dozen performers -- four bands in all -- stood enclosed in individual soundproof plastic cylinders. Most of the patrons were tuned in, wearing headsets to pick up one band's sound, and liquid crystal shades, flickering in synch with one group of cylinders, to render the other bands invisible. A few people were chatting quietly -- and of the room's five possible soundtracks, Maria decided that this tranquil near-silence best suited her mood. Besides, she never much liked using nerve current inducers; although physically unable to damage the eardrums (sparing the management any risk of litigation), they always seemed to leave her ears -- or her auditory pathways -- ringing, regardless of the volume setting she chose.

'Maybe later.'

She sat beside Aden, and felt him tense slightly when their shoulders brushed, then force himself to relax. Or maybe not. Often when she thought she was reading his body language, she was making signals out of noise. She said, 'I got some junk mail today that looked just like you.'

'How flattering. I think. What was it selling?'

'The Church of the God Who Makes No Difference.'

He laughed. 'Every time I hear that, I think: they've got to change the name. A God which makes no
