David Brin Quotes

Freedom was wonderful beyond relief. But with it came that bitch, Duty.

Demonstrating some of the proposed new techniques of encrypted uniqueness verification that can be embedded in each customer’s use-copy of a given work.

Each of us remains convinced that our own subjective viewpoint is more urgent than anyone else's—indeed, even more valid than the objective matrix that underlies so-called reality. After all, the subjective view is a grand theater. To be hero of an ongoing drama. It's why ideologies and bigotries survive against all evidence or logic.
Subjective obstinacy had advantages, Morris, when we were busy evolving into nature's champion egotists. It led to human mastery over the planet…and to our species nearly wiping itself out.

Experts were already casting doubt on an old dream — interstellar empire. If organic beings like us ever managed to voyage between stars, it would be through prodigious, exhausting effort. A tenacious species here and there might colonize a few dozen worlds with biological descendants. Even perhaps a small corner of the Milky Way. But hardly enough to dent the Fermi Paradox. Most organics would stay home.

All legends must be based on lies, Gordon realized. We exaggerate, and even come to believe the tales, after a while.

There isn’t one America anymore. If there ever had been.

That’s not how human psychology works. No, we tend to do lots of things without knowing why. We need excuses, though, so we rationalize! If an obvious reason for our behavior isn’t readily available, we invent one, preferably one that helps us think better of ourselves.

One great mystery is why sexual reproduction became dominant for higher life-forms. Optimization theory says it should be otherwise.
Take a fish or lizard, ideally suited to her environment, with just the right internal chemistry, agility, camouflage—whatever it takes to be healthy, fecund, and successful in her world. Despite all this, she cannot pass on her perfect characteristics. After sex, her offspring will be jumbles, getting only half of their program from her and half their re-sorted genes somewhere else.
Sex inevitably ruins perfection. Parthenogenesis would seem to work better—at least theoretically. In simple, static environments, well-adapted lizards who produce duplicate daughters are known to have advantages over those using sex.
Yet, few complex animals are known to perform self-cloning. And those species exist in ancient, stable deserts, always in close company with a related sexual species.
Sex has flourished because environments are seldom static. Climate, competition, parasites—all make for shifting conditions. What was ideal in one generation may be fatal the next. With variability, your offspring get a fighting chance. Even in desperate times, one or more of them may have what it takes to meet new challenges and thrive.
Each style has its advantages, then. Cloning offers stability and preservation of excellence. Sex gives adaptability to changing times. In nature it is usually one or the other. Only lowly creatures such as aphids have the option of switching back and forth.

I know you’re an unrepentant curmudgeon! You live to get a rise out of people, and someday your contrary habits will be your undoing.

But then, of course, it could have been worse. This may not be the best of all possible worlds. But Pangloss never met Murphy. And things could have been very much worse, indeed. The pyramid loomed ahead, separated by a broad river from the main part of an alien metropolis that had once been named Cal’mari.

The health of an enlightened and progressive society is measured by how vibrant is its science fiction, since that is where true self-critique and appraisal and hope lie.

In 1983, Michael W. Doyle commented on the common observation that democracies almost never wage war on one another. Understanding the reasons for this phenomenon may be crucial to our hopes for preventing devastating conflict in the next generation. Which attributes of democracy foster this essential trait of mutual nonaggression?

Beware of self-indulgence. The romance surrounding the writing profession carries several myths: that one must suffer in order to be creative; that one must be cantankerous and objectionable in order to be bright; that ego is paramount over skill; that one can rise to a level from which one can tell the reader to go to hell. These myths, if believed, can ruin you.
If you believe you can make a living as a writer, you already have enough ego.

Okay, so imagine we get past the next few rough decades and finally do what we should have back in TwenCen. Say we mine asteroids for platinum, discover the secrets of true nanotechnology, and set Von Neumann "sheep" grazing on the moon to produce boundless wealth. To listen to some of the rest of you, all our problems would then be over. The next step, star travel, and colonization of the galaxy, would be trivial.

But hold on! Even assuming we solve how to maintain long-lasting ecologies in space and get so wealthy the costs of star-flight aren't crippling, you've still got the problem of time.

I mean, most hypothetical designs show likely starships creeping along at no more than ten percent of the speed of light, a whole lot slower than those sci-fi cruisers we see zipping on three-vee. At such speeds it may take five, ten generations to reach a good colony site. Meanwhile, passengers will have to maintain villages and farms and cranky, claustrophobic grandkids, all inside their hollowed-out, spinning worldlets.

What kind of social engineering will that take? Do you know how to design a closed society that'd last so long without flying apart? Oh, I think it can be done. But don't pretend it'll be simple!

Nor will be solving the dilemma of gene pool isolation. In the arks and zoos right now, a lot of rescued species are dying off even though the microecologies are right, simply because too few individuals were included in the original mix. For a healthy gene pool you need diversity, variety, heterozygosity.

One thing's clear, no starship will make it carrying only one racial group. What'll be needed, frankly, are mongrels… people who've bred back and forth with just about everybody and seem to enjoy it."

The conflict is an old one. George Washington and other followers of the Enlightenment Movement wrote of their belief in an imminent maturity of humankind. The ancient and cruel feudal ways were splitting asunder at last; therefore, how could truth and freedom not prevail? In fact, the Enlightenment changed humanity forever. Yet its followers forgot something important — that each generation is invaded by a new wave of barbarians... its children. Just as Washington, Franklin, and their peers took joy in toppling the tyranny of Church and King, so the youths of the Romantic Movement thrived on jeering the lofty ideals of their predecessors.
