Once there were three tribes. The Optimists, whose patron saints were Drake and Sagan, believed in a universe crawling with gentle intelligence—spiritual brethren vaster and more enlightened than we, a great galactic siblinghood into whose ranks we would someday ascend. Surely, said the Optimists, space travel implies enlightenment, for it requires the control of great destructive energies. Any race which can't rise above its own brutal instincts will wipe itself out long before it learns to bridge the interstellar gulf.Across from the Optimists sat the Pessimists, who genuflected before graven images of Saint Fermi and a host of lesser lightweights. The Pessimists envisioned a lonely universe full of dead rocks and prokaryotic slime. The odds are just too low, they insisted. Too many rogues, too much radiation, too much eccentricity in too many orbits. It is a surpassing miracle that even one Earth exists; to hope for many is to abandon reason and embrace religious mania. After all, the universe is fourteen billion years old: if the galaxy were alive with intelligence, wouldn't it be here by now?Equidistant to the other two tribes sat the Historians. They didn't have too many thoughts on the probable prevalence of intelligent, spacefaring extraterrestrials— but if there are any, they said, they're not just going to be smart. They're going to be mean.It might seem almost too obvious a conclusion. What is Human history, if not an ongoing succession of greater technologies grinding lesser ones beneath their boots? But the subject wasn't merely Human history, or the unfair advantage that tools gave to any given side; the oppressed snatch up advanced weaponry as readily as the oppressor, given half a chance. No, the real issue was how those tools got there in the first place. The real issue was what tools are for.To the Historians, tools existed for only one reason: to force the universe into unnatural shapes. They treated nature as an enemy, they were by definition a rebellion against the way things were. Technology is a stunted thing in benign environments, it never thrived in any culture gripped by belief in natural harmony. Why invent fusion reactors if your climate is comfortable, if your food is abundant? Why build fortresses if you have no enemies? Why force change upon a world which poses no threat?Human civilization had a lot of branches, not so long ago. Even into the twenty-first century, a few isolated tribes had barely developed stone tools. Some settled down with agriculture. Others weren't content until they had ended nature itself, still others until they'd built cities in space.We all rested eventually, though. Each new technology trampled lesser ones, climbed to some complacent asymptote, and stopped—until my own mother packed herself away like a larva in honeycomb, softened by machinery, robbed of incentive by her own contentment.But history never said that everyone had to stop where we did. It only suggested that those who had stopped no longer struggled for existence. There could be other, more hellish worlds where the best Human technology would crumble, where the environment was still the enemy, where the only survivors were those who fought back with sharper tools and stronger empires. The threats contained in those environments would not be simple ones. Harsh weather and natural disasters either kill you or they don't, and once conquered—or adapted to— they lose their relevance. No, the only environmental factors that continued to matter were those that fought back, that countered new strategies with newer ones, that forced their enemies to scale ever-greater heights just to stay alive. Ultimately, the only enemy that mattered was an intelligent one.And if the best toys do end up in the hands of those who've never forgotten that life itself is an act of war against intelligent opponents, what does that say about a race whose machines travel between the stars?
And immediately we rushed like horses, wild with the knowledge of this song, and bolted into a startingly loud harmony: 'Rule Britannia, Britannia rules the waves; Britons, never-never-ne-verr shall be slaves!'and singing, I saw the kings and the queens in the room with us, laughing in a funny way, and smiling and happy with us. The headmaster was soaked in glee. And I imagined all the glories of Britannia, who, or what or which, had brought us out of the ships crossing over from the terrible seas from Africa, and had placed us on this island, and had given us such good headmasters and assistant masters, and such a nice vicar to teach us how to pray to God - and he had come from England; and such nice white people who lived on the island with us, and who gave us jobs watering their gardens and taking out their garbage, most of which we found delicious enough to eat...all through the ages, all through the years of history; from the Tudors on the wall, down through the Stuarts also on the wall, all through the Elizabethans and including those men and women singing in their hearts with us, hanging dead and distant on our schoolroom walls; Britannia, who, or what or which, had ruled the waves all these hundreds of years, all these thousands and millions of years, and kept us on the island, happy - the island of Barbados (Britannia the Second), free from all invasions. Not even the mighty Germans; not even the Russians whom our headmaster said were dressed in red, had dared to come within submarine distance of our island! Britannia who saw to it that all Britons (we on the island were, beyond doubt, little black Britons, just like the white big Britons up in Britannialand. The headmaster told us so!) - never-never-ne-verr, shall be slaves!
