Hari bristled. “Who says?”

 “Our considered opinion. You are impractical. Unwilling to make hard decisions. All our psychers agree with that diagnosis.”

 “Psychers?” Hari snorted derisively. Despite calling his theory psychohistory, he knew there was no good model of the individual human personality.

 “I would make a far better candidate, just for example.”

 “Some candidate. You’re not even loyal to your kind.”

 “There you have it! You’re unable to rise above your origins.”

 “And the Empire has become the war of all against all.”

 Science and mathematics was a high achievement of Imperial civilization, but to Hari’s mind, it had few heroes. Most good sci­ ence came from bright minds at play. From men and women able to turn an elegant insight, to find beguiling tricks in arcane matters, deft architects of prevailing opinion. Play, even intellectual play, was fun, and that was good in its own right. But Hari’s heroes were those who stuck it out against hard opposition, drove toward daunting goals, accepting pain and failure and keeping on anyway. Perhaps, like his father, they were testing their own character, as much as they were being part of the suave scientific culture.

 And which type was he?

 Time to raise the stakes.

 He stood, brushing aside the bowls with a clatter. “You’ll have my reply soon.”

 He stepped on a cup going out and shattered it.

 Voltaire shouted proudly, “I spent much of my career exiled for speaking Truth to Power. I’ll admit to some flaws in judgment, as when I fawned over Frederick the Great. Necessity shapes manners, I’ll remind you. I was courageous, yes—but snobbish, too.”

 [THOUGH A MATHEMATICAL REPRESENTATION]

 [YOU SHARE THE ANIMAL SPIRITS OF YOUR KIND]

 [STILL]

 “Of course!” Joan shouted in his defense.

 [YOUR KIND ARE THE WORST OF ALL VIVIFORMS]

 “Living things?” Joan frowned. “But they are of holy origin.”

 [YOUR KIND IS A PERNICIOUS BLEND]

 [A TERRIBLE MARRIAGE OF MECHANISM]

 [WITH YOUR BEAST URGE TO EXPAND]

 “You can see our inner structures as surely as we.” Voltaire

 swelled, popping with energies. “Probably better, I’ll venture. You must know that for us, consciousness reigns; it does not govern.”

 [PRIMITIVE AND AWKWARD]

 [TRUE]

 [BUT NOT THE CAUSE OF YOUR SIN]

 She and Voltaire were giants now, self-ballooned to stride across the simulated landscape. The alien fogs clung to their ankles. A proud way of showing their courage, perhaps, a bit full of self. Still, she was glad she had thought of it. These fogs held humanity in contempt. A show of force was useful, as she had found against the vile English several times.

 Voltaire said, “I held Power in contempt, usually, yet I’ll admit I was everlastingly hungry for it, too.”

 [THE SIGNATURE OF YOUR KIND]

 “So I am a contradiction! Humanity is a rope stretched between paradoxes.”

 [WE DO NOT FIND YOUR HUMANITY MORAL]

 “But we—they—are!” Joan shouted down at the fog. Though thin compared with them, the fogs clung like glue and filled the valleys with cottony gum.

 [YOU DO NOT KNOW YOUR OWN HISTORY]

 “We are of history!” Voltaire boomed.

 [THE RECORDS HERE IN THE MATHEMATICAL SPACES]

 [ARE FALSE]

 “One can never be sure of being read right, you know.”

 Joan saw in Voltaire an anxiety barely concealed. Though their opponent used a voice cool and dispassionate, she too felt the insi­ dious threat in its cast of words.

 Voltaire went on, as if to please a king in court, “A bit of histor­ ical example. I once saw in a churchyard in England, there to hail the bright Newton, a headstone, thus:

 ERECTED TO THE MEMORY of John McFarlane Drown’d in the Water of Leith BY A FEW AFFECTIONATE FRIENDS So you see, there can be mistakes of translation.” He lifted his elaborate courtier’s hat and made a sweeping bow. The hat’s plumed feather danced in a fresh wind. Joan saw that he was dis­ tracting the fog while trying to subtly blow it away.

 The fogs flashed orange lightning and swelled, enormous and purple. Thunderheads rose and towered above them.

 Voltaire showed only an arch scorn. She had to admire his gait as he whirled and confronted the gargantuan purple cloud-moun-tain. She remembered how he had waxed on about his dramatic triumphs, his legions of acclaimed plays, his popularity at court. As if to show off for her, he curled a lip into a sneer and invented a poem for the moment:

 “Big whorls have little whorls

 Which feed on their velocity,

 And little whorls have lesser whorls,

 And so on to viscosity.”

 The cloud hurled savage sheets of rain down upon them. Joan

 was instantly drenched and chilled to the bone. Voltaire’s glorious garb wilted. His face turned blue with cold.

 “Enough!” he cried. “Pity the poor woman at least.”

 “I need no pity!” Joan was genuinely outraged. “And you’ll not show weakness before the enemy legions.”

 He managed a jaunty smile. “I defer to the general of my heart.”

 [YOU LIVE ONLY AT OUR WILL]

 “Pray, do not spare us out of pity then,” Joan said.

 [YOU LIVE SOLELY BECAUSE ONE OF YOU]

 [SHOWED MORAL SELF]

 [TO ONE OF OUR LOWER FORMS]

 Joan was puzzled. “Who?”

 [YOU]

 Beside her materialized Garçon 213-ADM.

 “But this is surely a multiply-removed entity,” Voltaire snapped. “And a servant.”

 Joan patted Garçon. “A simulation of a machine?”

 [WE WERE ONCE OF MACHINE]

 [AND HAVE COME HERE TO DWELL]

 [IN NUMERICAL EMBODIMENT]

 “From where?” Joan asked.

 [ACROSS ALL THE TURNING SPIRAL DISK]

 “For—”

 [REMEMBER:]

 [PUNISHMENT DETERS BY LENDING CREDENCE TO

 THREAT]

 Voltaire asked, “So you said before. Taking the long view, eh? But what do you truly want now?”

 [WE TOO DESCEND FROM VIVIFORMS NOW EXTIN­ GUISHED]

 [DO NOT IMAGINE WE ARE FREE OF THAT]

 Joan felt a horrible suspicion. She whispered, “Do not provoke it so! It might—”

 “I would know the truth. What do you want?”

 [REVENGE]

 “Ugh.” Marq curled his lip.

 Hari smiled. “When food gets scarce, table manners change.”

 “But this—”

 “Hey, we’re payin’,” Yugo said sardonically.

 The menu was exclusively pseudoffal, the latest stopgap in

 Trantor’s food crisis. This foodworks had the whole run, livers and kidneys and tripe made in pristine vats. Not the slightest hint of actual animal tissue involved. Still, the voice menu reassured them in warm feminine tones, every item carried the true dank, visceral aromas of the gut.

 “Can’t we get some decent mealmeat?” Marq asked irritably.

 “This has higher food value,” Yugo said. “And nobody’ll be lookin’ for us here.”

 Hari glanced around. They were behind a sound shield, but still, security was essential. Most of the tables in the restaurant were taken by his Specials, the rest by well dressed gentry class.

 “It’s fashionable, too,” he said affably. “You can brag about coming here.”

 “Brag after I gag?” Marq sniffed the air, wrinkled his nose.

 “All the nonconformists are doing it,” Hari said, but no one got the joke.

 “I’m a fugitive,” Marq whispered. “People are still trying to hang those Junin riots on me. Taking a big risk to come here.”

 “We shall make it worth your while,” Hari said. “I need a job done by someone outside the law.”

 “That, I am. Hungry, too.”

 The voice menu assured them that there were, as well whole meals—of pseudo-animal, vegetable or transmineral ingredi-ents—boiled from within. “The newest foodie craze,” the menu gushed. “One bites into a firm shell and then ventures inward to a mellow, stewed interior of luxuriant implication.”

 Some items offered not mere flavor, aroma, and texture, but what the menu demurely described as “motility.” The featured item was a pile of red strands which did not just lie there limply in your mouth, but squirmed and wriggled “eagerly,” expressing its longing to be eaten.

 “You guys don’t need to torture me into collaboration.” Marq jutted his chin out, reminding Hari of a pan gesture used by Bigger.

 Hari chuckled and ordered a “gut sampler.” It was surprising how he could accommodate what would have revolted him only weeks before. When they had ordered, Hari put the deal on the table directly.

 Marq scowled. “Direct linkup? To the whole damned system?”

 “We want an interbridge to our psychohistorical equation system,” Yugo said.
