  I cannot wholly explain why this simple message destroyed our will to war. I cannot—and could not—look inside the minds of Li Tosh and Carman of Simoom and Leopold Soli and proclaim: “See, this is where the cool stream of devotion extinguished the flames of madness.” Why should we have even believed Her, that inhuman, capricious goddess? Perhaps our warring inside Her and our rape of the manifold had outraged Her; perhaps She wanted only to lure us on to our doom. I can only say that we did believe Her. We needed to believe Her. One hundred and twelve ships floated above the rings of the fourth planet, and we believed that the secret of the dying Vild (and perhaps the other secret) was close at hand. There came a moment, I think, when we looked out over the array of ships, and at the coffee−black spaces where the Infinite Sloop and the Blessed Harlot had recently been, and we were ashamed. We were not warriors; we were Pilots of the Order of Mystic Mathematicians and Other Seekers of the Ineffable Flame—I cannot explain why we each should suddenly remember this.

  We held a conclave, there near the thickspace. We sent our imagos ship to ship, listening to the voices of our “enemy” pilots, watching the lips of pilots we had known all our lives. It was as if we had awakened from a terrible dream. The sad Li Tosh, the anguished Sonderval grieving for Debra wi Towt, Soli with his death–ruined eyes and silent face—almost all the pilots agreed we must call a truce.

  “This has been a waste,” Soli’s imago spoke to me later in the privacy of my ship. “What fools we’ve been.”

  “Bardo is dead,” I told him.

  “So many dead.”

  “And Justine. How could you have killed them?”

  “I don’t know,” he said.

  Inside my pit I floated and rubbed my nose, which was so congested from filtering dry, recycled air that I breathed with difficulty. “You would have killed me too, wouldn’t you?”

  “I don’t know,” he said. And then, after a moment’s reflection: “Yes.”

  “But the war is over,” I said. “These murders diminish us. They’re barbaric. They make little men of all of us. I can’t kill anymore; I will not.”

  “Yes,” he said, “it’s over. The war.” He pressed his eyes, then said, “But between you and me, the race goes on, doesn’t it, Pilot?”

  “How could it not, then?” I agreed. “It goes on.”

  Because we were both Lord Pilots, Soli and I said a requiem for all the pilots that had died that day. Then each of us faced our ships and made our mappings. The stars vanished and the lightships fell through their windows into the manifold. So began our race to find the star Gehenna Luz before it exploded, into the lonely, deceptive heart of the Solid State Entity.

  The Great Ocean of Truth

  God created the integers, and all the rest is the work of man.

  Leopold Kronecker, Machine Century Constructivist

  The knowledge at which geometry aims is the knowledge of the eternal.

  The Plato

  Mathematics is a game. Its pieces are the axioms we create, and its rules are logic. That mathematics is occasionally useful to mechanics and pilots is accidental.

  Mahavira La,. third Lord Cantor

  I do not know what I appear to the world; but to myself I seem to have been only like a boy on the sea–shore, and diverting myself in now and then finding a smoother pebble or a prettier shell, while the great ocean of truth lay all undiscovered before me.

  Isaak Newton, first Lord Mechanic

  It is the strangest of phenomena that intelligence can shape the deep structures of the universe. How often I have had to admit this; how often I have had to contemplate this mystery. As I fenestered into the heart of the Entity, as I again penetrated that fathomless brain, I wondered again and again how Her great, rippling waves of intelligence created the wild, segmented spaces, the infinite loops (not to mention the omnipresent infinite trees) and the other dangers of Her interior manifold. She, Herself, strange to say, could not tell me. She did not know. She was not aware of every bubble and topological transformation which occurred within Her. When I learned this, I was surprised, though I should not have been. Is a pilot in dreamtime aware of the firing of each individual neuron within his brain? Can he ever fully understand the flow of blood through arteries, diffusing cell by cell through millions of capillaries, the hot rush of electrochemical impulses which is the fount of his pleasure? What is this thing we call intelligence? If intelligence is the result, the cumulative effect of billions of quantum and electrical events within the brain, how can intelligence turn itself outside–in to understand itself? It is an old problem with a simple solution: For any brain to be entirely aware of itself, it would have to be vastly larger than itself. Within the bounds of simple matter and energy, this is impossible. (Though our eschatologists have theorized that the Ieldra, and the mythical Elder Ieldra, have an infinite intelligence. And since infinite sets may contain subsets of themselves which are themselves infinite, they say it is possible that such godly intelligences can fully understand themselves. I do not know. Intelligence is not a set, and it is wrong to analogously apply the theory of sets in this manner. One would think the eschatologists would appreciate this simple fact.) And if we truly possess a free will, the problem grows worse, much worse. If I freely concentrated on a particular question—for instance, why would the Entity encourage one hundred and twelve pilots to enter Her brain?—if I thought this thought freely, I would be the cause of the fear and doubt which crackled through me. I would cause particular neurons within my limbic brain to fire. If I should somehow attempt to understand these impulses, the very act of my understanding would interfere with them. And then, at the very moment I thought I knew the shape of my fear, it would be gone, evaporated like snow crystals in the noonday sun.

  The Entity, of course, understood this as clearly as a pilot understands that two times two is four. Although She apparently wanted us to find the star Gehenna Luz, She did not really care about discovering the shape of the manifold within Her. We pilots could do that. She wanted only—at least this is my understanding—to think and be. If this tremendously concentrated thinking caused the manifold to distort into a series of infinite trees or to warp into a Danladi bubble—well, that was interesting, but not nearly so interesting as the openness or closure of rcalspace, and the other problems of the universe. To be sure, much as a man is aware that his visual cortex lies beneath the bone at the back of his head, She knew that certain pockets of the manifold were distorted in certain ways. This knowledge saved some of us pilots from stumbling into infinite trees, as I once had. She warned us away from the worst dangers. She provided us mappings, when She could, and She provided us with the fixed–points of Gehenna Luz. Had She not helped us this way, I believe few pilots would have dared to go on.

  For me it was terrifying to find myself once again journeying through that dark nebula that was the Entity. The dense, interstellar dust, the glowing hydrogen clouds, the cancerous black bodies, and always those goddamned mysterious moon–brains, as Bardo would say—whenever I fell out into realspace, I had difficulty imagining why I had once again, despite myself, returned to this strange hell. I was still full of the horror of war, and the afterimage of Bardo’s Blessed Harlot as it disappeared haunted me. I wondered where he was, almost moment by moment, wondered how he would face his death? I wondered where my fellow pilots were. I could not track their lightships across the Entity because the manifold was like bubbling, black mud. Too bad. Often, I wondered at the Entity’s purpose. Did She really want us to witness the death of a star? Or was it all just a cruel trick, Her way of exterminating the soul of an Order which had grown stale, obnoxious and bellicose?

  If She—this goddess whom the warrior–poet had once called Kalinda of the Flowers—if it was important to Her that we quickly reach Gehenna Luz, why didn’t She give us more help? Specifically, I wondered why She didn’t show us the solution to the Continuum Hypothesis. If we could prove the Hypothesis, we could have mapped from Per
dido Luz to Gehenna Luz in a single fall, in almost no time. Why had She provided us laborious mappings through Her twisted interior if a much simpler solution existed? Ah, but what if there was no solution? Or what if a solution existed, and She did not know—or care—what it was? (As a historical note, I should mention that there is an ancient, unrelated theorem of the same name. The Old Continuum Hypothesis states that there is no infinite set with a cardinality between that of the set of natural numbers and the set of points in space. For a century, this remained impossible to prove or disprove, until one of the first—and last—self–programming computers discovered the axioms of Generalized Set Theory and decided the question once and for all.)

  Of course it was arrogant and foolish of me to suppose that I might prove what the Entity perhaps could not. But for all my pains and adventures, I was still an arrogant man. I wanted badly to prove the Hypothesis. I needed to prove it, and to prove it before another pilot such as Soli proved it. All my life I had dreamed of proving it, and now great secrets lay before me if only the pure light of inspiration would illumine this most famous of theorems. I floated naked within my ship’s pit, all the while wondering where this inspiration might come from. From slowtime I passed into the white light of dreamtime, and the manifold opened to my mind. Strange are the pathways of a goddess’s brain: I entered a rare Lavi torison space and began in–folding through what I prayed would be a finite set of folds. Time slowed. I seemed to have forever to think my thoughts. My thoughts were like the dull glow of an oilstone; my thoughts were as weak as the light of a coldflame globe through a drifting cloud of snow on a winter night. I did not know where to seek inspiration. The great brain of my ship lay before me; its neurologics surrounded me in a web of electric intelligence, but it had been designed to compute, to reason by symmetry and heuristics, to manipulate logic structures, to store information, to do a million things which complemented and added to the mental powers of a human brain without replacing it. I could face my ship forever and be forever lost to the ecstasy of the number–storm, and still tremble for the fiery touch of inspiration. The sheer size of a brain, I thought, did not necessarily determine its talent for creating mathematics. Perhaps even the Entity—and here I was being utterly foolish—had little real interest or talent for pure mathematics. And then I had another thought as clear as the Timekeeper’s glass: If I were to prove the Great Theorem, the inspiration would have to come from somewhere within myself.

  I am a mathematical man. I am a curious man. I have always wondered at the nature of mathematics, and at my own nature as well. What is mathematics? Why should mathematics describe the laws of the universe so exactly? Why should our minds’ seemingly arbitrary creations and discoveries fit so well this mad, swirling blizzard we call reality? For example, why should gravity (to use the model of newtonian mechanics) act between two objects according to the inverse of the square of the distance separating them? Why doesn’t it act according to the second and a half power, or the two point zero one five and so on power? Why is everything so tidy and neat? It may be, of course, that the human brain is so puny that it can discover only the simplest, the most obvious of universal laws. Perhaps there remains an infinity of laws so hopelessly complicated that they would be impossible to state. Had gravity acted more complexly, The Newton probably never would have found an equation to describe it. Who knows what wonders will forever remain hidden from the mathematical sight of man? This explanation, however, favored by the eschatologists, still does not explain why mathematics works as it does, or why it even works at all.

  What is mathematics? I have turned this question in my mind, turned and returned to this mystery all my life. We create mathematics as surely as we create a symphony. We manipulate our axioms with logic as a composer arranges musical notes, and so the holy music of our theorems is born. And in a different sense we also discover mathematics: The ratio of a circle’s circumference to the diameter remains the same for human minds and for aliens of the Cetus cloud of galaxies. All minds discover the same mathematics for that is the way the universe is. Creation and discovery; discovery and creation—in the end I believe they are the same. We create (or discover) undefined concepts such as point, line, set and betweenness. We do not seek to define these things because they are as basic as concepts can be. (And if we did try to define them, we would make the mistake of The Euclid and say something like: A line is breadthless length. And then, using other words we would have to define the concept “breadthless” and “length.” And so on, and so on, until all the words in our finite language were eventually used up, and we returned to the simple concept: A line is a line. Even a child, after all, knows what a line is.) From our basic concepts we make simple definitions of mathematical objects we believe to be interesting. We define “circle”; we create “circle”; we do this because circles are beautiful and interesting. But still we know nothing about circles. Ah, but some things are obviously true (or it is fun to treat them as if they were true), and so we create the axioms of mathematics. All right angles are congruent, parallel lines never intersect, parallel lines always intersect, there exists at least one infinite set—these are all axioms. And so we have lines and circles and axioms, and we must have rules to manipulate them. These rules are logic. By logic we prove our theorems. We may choose the natural logic where a statement is either true or not, or one of the quantum logics where a statement has a degree of probability of trueness. With logic we transmute our simple, obvious axioms into golden theorems of stunning power and beauty. With a few steps of logic we may prove that in hyperbolic geometry rectangles do not exist, or that the number of primes is infinite, or that aleph null is the smallest infinity that exists, or that…we may prove many wonderful things which are not obvious at all; we may do this if we are very clever and if we love the splendor of the number storm as it rages and consumes us, and if we are filled with the holy fire of inspiration.

  What is inspiration? From where does it come? As I fenestered through the torison space, the Lavi Curve Theorem and the Second Transformation Theorem were as beautiful as diamonds, and I was full of wonder. Where does mathematics come from? How is it born? Yes, we have axioms and logic and concepts such as “line,” but where do these abstractions come from? How is it that even a child knows what a line is? Why do the Darghinni, who are as alien as aliens can be, think according to the same logic as human beings? Why should this be so?

  I segued through the last fold in the torison space; my ship dropped into realspace, like a flea popping out of the shaken robes of a harijan. I looked at the veiled stars of the Entity, and I thought of the age–old answer of the cantors. Mathematics is a special language, and language is born within the brain. Our brains have evolved for fifteen billion years from the brains of man–apes and back, from the simpler mammalian brains, from the ganglia and nerve clusters of creatures slithering or swimming through the warm salt water of our distant past. And back still further to the bacterial spores which carried life to Old Earth. But from where did these spores come? Did the Ieldra create them? Who created the Ieldra? What is life? Life is the information and intelligence bound within DNA, and life is the explosive replication of protein molecules, and life is the carbon, hydrogen, oxygen, and nitrogen which exist or are born with the cores of the stars. And the universe gives birth to stars; the universe is a vast, star–making engine; the universe brought forth Bellatrix and Sirius and the blue giant stars of the greater Ede Cluster; from stars such as Antares and the First Canopus the stuff of life is made. Every atom of ourselves was assembled in some faraway, heavenly fire. We are the children of the stars, the universe’s creation. If our star–born brains conceive “line” and the other elements of language, should we be surprised that “line” is a natural and meaningful concept within that universe? Is it a wonder that the logic of the universe is our logic, too? The cantors are fond of saying that God is a mathematician. They believe that when we create the special language of mathematics we are learning to speak
the language of the universe. We have all of us, we pilots and mathematicians, uttered the sounds of this language, in however an infantile and primitive form. Once or twice, while contemplating the wonderful fit of mathematics to the contours of spacetime and to the undulations of the manifold, I have felt that the universe was talking to me in its special vocabulary, if only I could listen. How could I learn to listen? How could I learn to speak more elegantly the pure tones of mathematics? What is inspiration?

  I journeyed on, and my ship seemed like a dark, stale tomb imprisoning me, darker by far than the Timekeeper’s stone cell. As a germinated seed seeks its way out of the ground into the light of day, I longed to break free of the old thoughtways that stifled me and restrained my inspiration. How I longed to prove the Great Theorem! But at the same time that I had longings, I had a certain dread, too. I wondered, again and again, at the nature of my own intelligence. From where did my powers of scrying and remembrancing spring? What other powers might I someday gain? If I did somehow prove my theorem, would the proof really be my own? Or would it be merely the creation of the Agathanian’s information virus? Could I dare to call forth the seed of inspiration within me, to try to shape that seed as it grew, to taste the bittersweet fruit it might bear?

  I followed the Entity’s mappings across a series of thickspaces. Once, I fell out into realspace as dark and empty as the intergalactic void. I nearly panicked, then. But I found that I was actually in the middle of a thickspace! The point–sources were stived as closely as the black eggs in the belly of a jewfish. How this could be so I did not know. Only stars or other matter (or intelligence) can deform space to create a thickspace. I quickly opened a window, and I segued into the manifold. I fell into dreamtime as I thought about this odd thickspace. If the brain of the Entity could contain such wonders as a starless thickspace, what wonders might lie within my brain? Suppose I really tried, tried so hard my eyes burned like coals and my brain’s blood surged like an ocean—suppose I tried for the thousandth time to prove the Continuum Hypothesis?
