Greg Bear "The Forge of God"

President Crockerman asked, "Do you believe in God?" Without a moment's hesitation, the Alien replied "We believe in Punishment."

Greg Bear, born in 1951, is a Hugo and Nebula award winning author of some three dozen novels and short story collections. A writer of hard science fiction, he often focuses on biology, especially diseases and microbiology. His Nebula winning Darwin's Radio and its sequel Darwin's Children explore political repression, retroviruses and speciation. Vitals deals with bacteria as communal organisms, as well as devling entertainingly into conspiracy theories. (You will never guess who the KGB has kept alive in a fishtank in the middle of modern Manhattan.) His Hugo winning Blood Music (expanded from a Nebula Winning novella) portrays an apocalyptic transformation of the nature of the self brought on by the escape of genetically enhanced human blood cells down a bathtub drain.

One of his best reviewed books, The Forge of God, deals not with microbiology, but with the Fermi Paradox. If the galaxy is full of alien life, then why aren't they here yet? Why have aliens not yet visited the earth? The answer quickly becomes evident. First, the Jovian moon Europa disappears. Then mountains appear overnight where there was none before in Australia and in Death Valley. Robots promising a golden age emerge from the Australian mountain. In America an enigmatic alien is found near death, apologizing for bearing bad news, and telling the president its simple punitive theology.


Bear is not only a great story teller, he is an artist of literary caliber. His works feature complex interwoven plots with twists that surprise the reader yet fit seamlessly together without resorting to the arbitrary deus ex machina. His characters are well developed, strongly individuated. In Forge of God, the president, a likeable man, is driven to the edge of insanity by the revelation that the world will soon end. His response is religious in form, but Bear does not portray him as some mindless religious stereotype, and, in a touch of sophistication, the populist preacher that Crockerman summons to advise him in fact doubts the appropriateness of a religious response to the physical threat and turns to the president's science advisors to admit that he is out of his league and that the Presdient could perhaps use some more conventional strategic advice.

Whether likening squiggles of toothpaste to little blue tadpoles in the sink or graphically comparing the City of Los Angeles, its citizens transformed into blobs of jelly and sentient fungal growths by a plague, to a vision from a Max Ernst painting, Bear uses vivid concrete images that often approach the poetic in their evocativeness. One can form a detailed mental image of his characters' physical traits and their bearing and gestures. Conflict is well motivated, antagonists act not just out of opposition, but because of an alternate, if mistaken view of the good. Psychology is made apparent through telling thoughts and dialog. Yet facts not known to the characters are not revealed to the reader until they become clear to the protagonists. This maintains a sense of realism and especially of suspense. Is the dying alien in league with the supposed robot benefactors? Is the earth truly at risk? The aliens provoke paranoia in some and disbelief in others. What, we ask, are the plots within the plots?

If you have not read Bear, you can think of him as combining the fast-paced plots of Larry Niven and his knack for contemporary social commentary with the analytic depth and literary quality of Frank Herbert. While I have not been able to get into his The Way, Queen of Angels, or Songs of Earth and Power series, I have thorougly enjoyed all the books of his which I have read past the first few dozen pages. The apocalptic Forge of God, with its epic and very differrent but highly complimentary sequel, Anvil of Stars, is a good place to start.



Read the excellent article on Bear at Wikipedia. Check out his official website. And pick up one of his books, today. The painting above, Into The Forge of God, by Alan Gutierrez depicts the launch of a NASA probe into Jupiters atmosphere and was used on the cover of Bear's novel.

A God's Eye View of the Solar System Tonight

There is a conjunction of Venus, Jupiter and the moon tonight, just after sunset. If you consider that Jupiter, Venus and the Earth are all in the same plane focused on the sun, you can actually see the plane of the solar system. The moon is at a tilt and is outside the plane. (Draw a line from the crescent moon to the sun, just over the horizon, and you will see this.) If you imagine in your head the plane of the solar system and the moon lying outside that plane you will form a three dimensional image of the solar system. This is a unique opportunity to the planets not just as dots on a flat sky, but actually to "see" the solar system from a god's eye view, and a good time to dust off your digital camera.

Google Mars

You are probably familiar with Google Earth, the satellite image website that lets you zoom in from space on any site on the planet. If you aren't familiar with the site, you should check it out immediately. No Roman emperor or god on Mount Olympus could command such wonders as the poorest of citizens with an airport connection or a card to his local library. But even if you have seen Google Earth, have you checked out Google Mars? Through NASA and the Hubble Telescope we can see wonders so grand that mere words cannot describe a millionth of their splendor; the surface of distant stars, the creation of new suns, millions of galaxies billions of years distant.



Google Mars lets us zoom in on the Red Planet as if it were in our living rooms, and not a barely visible red speck in the night sky some 100 million miles away. You can look at Mars photographed in visible light or infrared or you can enjoy the false-color relief map which doesn't show any canals, but which does show plain signs of crater impacts, flowing water, and mountains over ten miles high.

Immortal? No. Eternal? Maybe. (Part I)

The question of immortality doesn't arise to animals, they can't conceive of time in the abstract or of their own deaths. But humans can look at both the distant future and the deep past. Indeed, every time you look at the sky, you see history. The stars of Orion, for instance, lie some 500 light years away, and ago.

The science of comparative linguistics deals with the past as well. By comparing related languages we can deduce the nature of the mother tongue which gave rise to them, even though this dialect may be long dead, and was never written down. For example, the English words wit and wise, the Latin video, and the Greek idea all come from the same Proto-Indo-European root wid- meaning to see, and hence to know. The Proto-Indo-European language is not attested in any written form. It was spoken by pre-literate horse nomads in the area north of the Black Sea some six thousand years ago, long before Sumer or Stone Henge or the Pyramids. We know it existed because we know its descendents. See my post on Calvert Watkins' Proto-Indo-European dictionary. No current descendent of Proto-Indo-European uses the form "weid-" today. Over the millennia the /d/ in "weid-" changed to a /t/ in Proto-Germanic and hence English. In Latin the /w/ became a /v/ as we see in modern French and Spanish. In Greek the /w/ dropped out, leaving only "idea."

Most of our vocabulary results from either our native stock inherited through Proto-Germanic or comes through other Branches like Greek and Latin, as well as Celtic, Slavic, Indo-Iranian and the like. Other Branches include Baltic, (e.g., Lithuanian,) Albanian and Armenian. And last century the extinct Hittite and Tocharian were discovered in Anatolia and Central Asia.

Ferdinand Saussure
, famous mostly today to postmodernists who have developed relativist theories based on the notes for his university course published and modified by his students after his death early last century, was a brilliant theoretician who studied an anomaly he saw in the reconstructed roots of the Indo-European proto-language. Most IE verbs had the root form noted by linguists as CVC- or more specifically CeC- meaning consonant-vowel-consonant. And in such root the vast majority had the specific vowel /e/. Examples include *bher- "to carry" (Latin fer-o English bear Greek pher-ein) and *pe(r/z)d- "to fart" (Latin "pest-" Slavic "perditi"). But there were also a large number of roots with either no first or last consonant, and the majority of these roots had some other vowel than /e/ as their root vowel. Examples include *ag- "to lead/plow" (English "acre" and from Latin "agriculture") or *sta- "to stand, to stay" as in Latin "sta-tus" or Greek "stasis". Saussure wondered if there might not have been some now unknown letter that existed in Indo-European but which, becoming silent, had affected the sound of those vowels as had silent /e/ in English which lengthens the vowel of breath to breath or of wisdom to wise. Maybe *sta- was originally *steH where the lost consonant (probably a sound made in the throat) changed the vowel before it left.

Saussure came up with the theory as a university student. Others found this theory fascinating, and suggest some /h/-like sound. But how to prove it? Saussure died in 1913. In 1915 and subsequently the Czech linguist Bedrich Hrozny published his translation of the newly discovered Hittite language of ancient Anatolia. It turned out that Hittite was an Indo-European tongue, and that this pre-Greco-Roman dialect exhibited /h/-like sounds just where Saussure had predicted them.

Saussure, using the scientific method, had predicted the sounds that existed in a language he had never heard, and that had been unspoken for millennia. Most people know linguistics as an exotic academic subject. Professor Doolittle in My Fair Lady springs to mind. No one can make money from historical linguistics. utterly impractical, it is a perhaps seen as pursuit of racists, cranks and the English upper class. Perhaps. But like the paleontologists impractical study of fossils, the astronomers impractical study of stars, and the historians impractical study of long forgotten wars, historical linguistics does have a connection with the human soul, one on the level of fine art, it connects us with the universe on a scale that far exceeds our here-and-now moment-bound existence. Far from showing us how small we are, such studies connect us with the timeless, and show how great is the mind of man. Such knowledge may not make us immortal, but it does connect us with the eternal.

Citizen of the Galaxy

While usually considered one of his "juvenile" books, Citizen of the Galaxy is one of Robert Heinlein's best. A boy sold into slavery is purchased by a legless mendicant who teaches him what amounts to the rational egoism of a Stoic, a Jesuit, or perhaps a Randian. The beggar is more than he seems, and so is the boy.

Leaving the slave planet, a world of Levantine decadence, the hero becomes a passenger on a family-owned trading spaceship where the crew speak what happens to be Finnish and live according to a two clan phratry system divided as well from outsiders, the "Fremdi." The social rules are very complex, one may not fraternize with the other clan, but when it comes time to take a wife, one may not marry within one's own clan. Heinlein does not make the fact that the ship members are Finns living according to ancient folk custom explicit, and I only figured this out after I had studied archeology and anthropology and then re-read the book after about a decade.

Having lived under a Middle Eastern-style despotry and aboard a clannish trading vessel with a gypsy-like attitude toward strangers, the hero then makes a transition into an British style navy where again he must learn a totally new way of life. He not only learns Western values, he learns his own birth identity and the role he can play, should he choose to, as a citizen of the galaxy.

The book is quite a broadening experience, for its hero and for the reader, and Heinlein's research and fidelity to the systems he describes is impressive. Except for the space element, the story might have been set on 19th century Earth. One of the best aspects of Heinlein "science-fiction" is that it is not alien or technology driven, but plot and character driven. Some of Heinlein's books have the flaw that they lack endings. Yet this story is fully integrated and does not disappoint. Do not be put off by the fact that the main character is an adolescent. The book is fully suitable for adults and I have read it three times. Heinlein's love for humanity, his cosmopolitan sophistication and his nevertheless unending advocacy for the superiority of universal liberal values show that Heinlein himself most assuredly deserved the title Citizen of the Galaxy.

Atheism alone is a rotting corpse. I substitute art and nature for God - the grandeur of man and the vast mystery of the universe.



NASA's Hubble "Deep Field" above portrays not stars - almost every point of light is a distant galaxy. If the Deep Field image itself is sublime, how much more impressive is it that we as humans can comprehend it?

Compare Coreggio's "Jupiter and Io," 1532, left with that of NASA's 2001 Cassini Probe, with the amber-colored Io and the white Europa in Transit across the face of Jupiter, right. There is no separating the "mystery of the universe" from the "grandeur of man" who surveys it.
