Human origins - and evolution. Patterns of cooperation and competition

I'm avoiding politics once again this time, in order to dive into the endlessly fascinating topic of human origins. And hence first, for your holiday shopping.... 

... a while back I suggested the perfect gift for that anthropologist or paleo-historian you know (either professional or amateur!) Or else your role-playing aficionado. My way-fun role-playing game TRIBES simulates life in the stone age! 

Can you hunt and gather and woo and connive to have the most offspring successfully reach adulthood? Only be careful competing! You only win if the the tribe survives!

Alas, folks reported interest last time... but no way to actually order the game!

Well, Steve Jackson has fixed the glitch. You can now order and play this fun diversion that's also highly pertinent to today's topic! 

== News about human origins and evolution ==

Scientists are advancing with synthetic evolution: At 493 genes, the minimal genome of M. mycoides JCVI-syn3B is the smallest known free-living organism, artificially culled-down to the absolutely minimum number that’s viable by folks at the Craig Venter Institute. In comparison, many animal and plant genomes contain more than 20,000 genes. So far, the simplest organism would have no functional redundancies or useless spacers. Note that it requires the researchers to supply food and ideal conditions. Which leads to their next step… altering conditions to see if evolution takes place.

Spoiler alert. It does.

At the opposite end of the scale... Neanderthal genes! Was there a penalty for promiscuity around 50,000 BCE?  People with roots outside Africa tend to have about 2% Neanderthal (or else Denisovan) DNA in their genome. So statistically, by random chance, you would expect Neanderthal DNA to collectively account for around 2% of the genetic risk of disease. Not in all cases, it seems: "But here we find that 8.4% is explained by Neanderthal gene flow," much more than is expected by chance alone.”  


It is so tiresome when sci journalists flub their reporting. Take these reports that the human ancestral line almost died out due to low populations about 800,000 years ago.  Yes “bottlenecks” are very interesting! A recently discovered ‘y-chromosome bottleneck’ around the time of early farming towns, has huge implications! As for these news stories: yes, there was likely a time when Homo Heidelbergensis & Antecessor (ancestor of Homo Saps and Neanderthals) were a small, isolated population, and surviving that isolation helped them to thereupon differentiate and speed our evolution. 


But, this was not about ‘the human line almost dying out’! These articles ignore the fact that very close cousins to Heidelbergensis - Homo Erectus - were everywhere in the Old World with no bottleneck. An isolation bottleneck was likely HOW we surged ahead of Erectus – evolution flourishes on such cycles. But Erectus was still around and would likely have spun off another isolated population. And maybe super-brain sapiens might NOT have happened!  See my speculations in Existence. Still, flawed reporting.


Human origins were definitely in Africa, stretching back to Australopithecus – “Lucy’ and her upright-walking kin. But further back to the ancestors of ALL apes? It appears that earlier hominids not only evolved in western and central Europe but spent over 5 million years evolving there and spreading to the eastern Mediterranean before eventually dispersing into Africa. Recent findings establish Anadoluvius turkae as a branch of the part of the evolutionary tree that gave rise to chimpanzees, bonobos, gorillas and humans.


 But sure, long after that, human genetic diversity in non-African populations appeared to have been shaped primarily by an out-of-Africa dispersal 50 or so thousand yr ago (kya). (As I describe in Existence.) With a major shift in reprogramming-by-culture. But somewhere around 7000ya there was another huge effect. Arrival of agriculture, towns and kings led to a Y-Chromosome bottleneck when only a small fraction of males got to breed. Then, rather quickly, actual cities got larger, law happened, and the great culling of males appears to have stopped... though not feudalism, dominating 99% of our ancestors.

We can do - and have done - better than that failed social norm.

== Did we evolve all the things that make us what we are? ==


I want to just drop in here a few thoughts about Richard Dawkins (famed author of The Selfish Gene , The Blind Watchmaker, and The God Delusion). Down in the comments community here at "Contrary Brin" (the very best such community online!), some opined a while back about Dawkins's belief that humans have no behaviors that did not arise from evolution. And I also must demur. What Dawkins etc. (and nearly all others) ignore is the emergent effects that occur when one layer of activity creates a new, ‘higher” layer.

Cells are vast communities of sub-cellular entities that do their various tasks & business in a manner that is generally at least as much competitive as cooperative, making and ‘selling’ chemicals and structures to each other, much like an economy. Yet the cell seems from the outside to be a consistent, self-cooperative entity.

In Earth I describe how this same effect happens at the next layer between cells in a macro organism, especially during fetal development, when proto-neurons compete with each other savagely, over growth factors, resulting in whole ecosystem structures – jungles and forests and deserts, across the developing infant brain: structures that combine into vastly better mental processes, wherein many next-layer personality drives and components continue to compete across life… yet, the thing that emerges - an individually identifiable human being - portrays with some verisimilitude a unitary organism, actively and effectively pursuing goals…

…goals that change as the organism satisfies ever-higher layers of Maslow’s hierarchy of needs. All the way to abstractions that the cellular and mammal and ape and caveman brains that dwell inside our cortex could never begin to perceive, let alone understand.

And sure, often these higher ‘value’ goals (e.g. religion) can often be just surface justifications for more brutal, lower drives like vengeance, jealously, fear and avarice. And yet… 50,000 years ago (I believe, and argue in Existence), there came a new layering as humans became able to re-program their thinking modes completely via culture, leading to many subsequent major, 'renaissance' shifts in our tools, societies and things we can perceive/contemplate.

And of course this progression continues, as human individuals group themselves in cooperative - but also competitive - associations like families, tribes, communities, towns and nations. And civilizations, which aren't entirely the same thing. 

The crux: Dawkins is completely off-base if he thinks he can ascribe the emergent outcomes from those new and vividly unpredictable layers entirely to earlier evolved selection.  

Every phase and every level reveals the truth that nether cooperation nor competition can explain this, alone. Each is entangled in layer after layer of complexity.

== Where our evolved natures collide with policy? And with AI? ==

Our evolved natures interact fretfully with new technologies. Take recent cries that new generative AI systems may decipher and interpret our personal DNA!  Yes, that could be worrisome! A tool for criminals and oppressors and bigots. As illustrated in the excellent film Gattaca – that DNA is already everywhere. You shed it in flakes of skin wherever you go. 

But that's the point! As shown in that flick, collection and decipherment of our DNA will be trivial and banning all that is a mug's game. What matters - a point I’ve been pushing since the 1990s, in The Transparent Society and elsewhere - is that hiding will neither preserve privacy nor prevent your data being used against you

But what matters is not blinding others; it is preventing others from using your information to harm you. There is a possible solution, then. Not by hiding, but by aggressively ripping the veils away from malefactors who might do that sort of thing!

Gravitational waves, Snowball Earth ... and more science!

Let's pause in our civil war ructions to glance yet again at so many reasons for confidence. On to revelations pouring daily from the labs of apprentice Creators!

== How cool is this? ==


Kip Thorne and his colleagues already achieved wonders with LIGO, detecting gravitational waves, so well that it’s now a valuable astronomical telescope studying black holes and neutron stars. But during down time (for upgrades) scientists took advantage of the laser+mirrors combo to ‘chill’. “They cooled the collective motion of all four mirrors down to 77 nanokelvins, or 77-billionths of a kelvin, just above absolute zero.” Making it “ a fantastic system to study decoherence effects on super-massive objects in the quantum regime.”


“…the next step for the team would be to test gravity’s effect on the system. Gravity has not been observed directly in the quantum realm; it could be that gravity is a force that only acts on the classical world. But if it does exist in quantum scales, a cooled system in LIGO—already an extremely sensitive instrument—is a fantastic place to look,” reports Isaac Schultz in Gizmodo


And while we're talking quantum, a recent experiment in Korea made very interesting discoveries re: wave/particle duality in double slit experiments that quantifies the “degree” of duality, depending on the source. 


All right, that's bit intense, but something for you quantum geeks. 


== And… cooler? ==


700 million years ago, Australia was located close to the equator. Samples, newly studied, show evidence that ice sheets extended that far into the tropics at this time, providing compelling evidence that Earth was completely covered in an icy shell, during the biggest Iceball Earth phase, also called (by some) the “Kirschvink Epoch.” So how did life survive?

The origins of complex life: Certain non-oxidized, iron rich layers appear to retain evidence for the Earth’s orbital fluctuations from that time.  Changes in Earth's orbit allowed the waxing and waning of ice sheets, enabling periodic ice-free regions to develop on snowball Earth. Complex multicellular life is now known to have originated during this period of climate crisis."Our study points to the existence of ice-free 'oases' in the snowball ocean that provided a sanctuary for animal life to survive arguably the most extreme climate event in Earth history", according to Dr. Gernon of the University of Southampton, co-author of the study.


== Okay it doesn’t get cooler… Jet suits! == 


Those Ironman style jet suits are getting better and better!  Watch some fun videos showcasing the possibilities - from Gravity Industries.  The story behind these innovative jet suits is told in a new book, Taking On Gravity: A Guide to Inventing the Impossible, by Richard Browning, a real-life Tony Stark.


== Exploring the Earth ==


A fascinating paper dives into the SFnal question of “what-if” – specifically if we had been as stupid about the Ozone Layer as we are re climate change. The paper paints a dramatic vision of a scorched planet Earth without the Montreal Protocol, what they call the "World Avoided". This study draws a new stark link between two major environmental concerns - the hole in the ozone layer and global warming – and how the Montreal Accords seem very likely to have saved us from a ruined Earth.


Going way, way back, the Mother of Modern Gaia Thought – after whom I modeled a major character in Earth – the late Lynn Margulis, has a reprinted riff in The Edge – “Gaia is a Tough Bitch" - offering insights into the kinds of rough negotiations between individuals and between species that must have led to us. Did eukaryotes arise when a large cell tried and failed to eat a bacterium? Or when a bacterium entering a large cell to be a parasite settled down instead to tend our ancestor like a milk cow? The latter seems slightly more likely!


Not long after that, (in galactic years) some eukaryotes joined to form the first animals – sponges – and now there are signs this may have happened 250M years earlier that previously thought, about 890 Mya, before the Earth’s atmosphere was oxygenated and surviving through the Great Glaciation “Snowball Earth” events of the Kirschvink Epoch.


Even earlier!  Day length on Earth has not always been 24 hours. “When the Earth-Moon system formed, days were much shorter, possibly even as short as six hours. Then the rotation of our planet slowed due to the tug of the moon’s gravity and tidal friction, and days grew longer. Some researchers also suggest that Earth’s rotational deceleration was interrupted for about one billion years, coinciding with a long period of low global oxygen levels. After that interruption, when Earth’s rotation started to slow down again about 600 million years ago, another major transition in global oxygen concentrations occurred.” 


This article ties it in to oxygenization of the atmosphere, because cyanobacteria need several hours of daylight before they can really get to work, making oxygen, which puts them at a disadvantage when days are short. Hence, when days got longer, they were able to really dig in and pour out the stuff. Hence our big moon may have helped oxygenate the atmosphere.


I have never been as big fan of the Rare Earth hypotheses for the Fermi Paradox and especially the Big Moon versions, which speculate some kinda lame mechanisms. But this one sorta begins to persuade. It suggests the galaxy may be rife with planets filled with microbes, teetering on the edge of the rich oxygen breakout we had a billion years ago.


A Brief Welcome to the Universe: A Pocket Sized Tour: a new book from Neil deGrasse Tyson and astrophysicists J. Richard Gott and Michael Strauss - an enthusiastic exploration of the marvels of the cosmos, from our solar system to the outer frontiers of the universe and beyond.

Uchuu (outer space in Japanese) is the largest simulation of the cosmos to date - a virtual universe, which can be explored in space and time, zooming in and out to view galaxies and clusters, as well as forward and backward in time, like a time machine.

== On to Physics ==


A gushy and not always accurate article nevertheless is worth skimming, about Google Research finding “time crystals,” which can flip states without using energy or generating entropy, and hence possible useful in quantum computing.

Science updates!


It's hard to evade politics, even in a weekend science update. for example when a top Republican factotum declares: “Science is a Democrat thing.” 

Um. They say it proudly! Yes, science, but also every single fact-based profession. Including medicine, law, teaching, journalism and those "deep state" enemies -- the Intel/FBI/military officer corps -- who know that fact and science and climate change are real.


== Long ago at least they had an excuse for ignorance... ==

As we re-examine our distant past...

We’re finding numerous past eras when the male population in a region was winnowed to a narrow gene pool or else replaced by newcomers. One massive swing happened about 12,000 years ago, about the same time that two technologies might have exacerbated male death rates: agricultural kingdoms and the availability of plentiful beer. (This is actually my own theory, based upon traveller reports from Polynesia and other places that told of kings ordering the instant death of offending louts. It would help explain human resistance to addiction, which though terribly imperfect is greater than in most species.)

Now comes evidence that a mass migration of males transformed the genetic make-up of people in Spain during the Bronze Age. It remains unclear whether there was a violent invasion or whether a male-centric social structure played an important role.”  Interesting article!  And yet, in my “contrarian gadfly” role, I must point out that while dominance by top king-chief-patriarchs seems the most likely explanation, there IS another way that a Y chromosome winnowing could have occurred. 

Female dominance. There have been a few cases of matriarchy in which women councils exerted strong control over which males were allowed to breed. It is quite conceivable (get it?) for such councils to enforce hypergamy – preference to share those males who meet strict standards, rather than “settle” for average. 

A mild version of this practice was seen among the Cherokee and Iroquois, for example.  Yes, our sad litany of nasty and oppressive patriarchies was far more common. But it’s wrong simply to assume that Y chromosome winnowing happened because of inter-male strife. It might have been female selection, which is actually the great driver of evolution in many non-human species.

== More evidence from the past ==

And the Denisovan story gets even more complicated and strange: our Denisovan cousins may have mated with modern humans as recently as 15,000 years ago.

A fossil discovery in North Dakota is strongly believed to be a fish that was blasted and killed precisely the very day that the Cretaceous ended with the Chicxulub meteorite impact, 66 million years ago, the most incredible (and precise) paleontological discovery of the century, so far. If this story is even 5% true...wow. Just wow.

Meanwhile a new fossil trove in China - the Qingjiang biota - has yielded thousands of Cambrian period specimens, with dozens of new species, yet to be named.

Gabonionta are the earliest multicellular macroscopic organisms discovered so far, vastly older –by almost 4x ! – than previous evidence for complex life. Known only from their fossilized mucous trails in black shale from Gabon. Likely something like colonial amoebae or slime molds, they seem to have appeared almost right after Earth finally got appreciable oxygen in its atmosphere. Good science reporting.

My old Caltech housemate Joe Kirschvink has done it again, proving (with colleagues) that humans have a small but verified sensitivity to magnetic fields. 

== Tech updates ==

Via Peter Diamandis: Researchers at Boston University have mathematically designed a 3D acoustic metamaterial that can block up to 94 percent of noise flowing through it. Most dramatically, however, the 3D-printed structure reflects noise-producing vibrations without impeding the passage of light or airflow itself.

GauGAN, from NVIDIA, may be the “MS Paint for the AI age.” Using a generative adversarial network (GAN) trained on 1 million Flickr images, GauGAN can create photorealistic images from just a few lines drawn by a user. As an example, a user could click on “tree,” draw a line, and GauGAN will create an image of a tree trunk.

And “Google has successfully shrunk its speech algorithm storage demands down to 80MB, rendering its speech recognizer small enough to fit on your smartphone, and work offline.”

A world game-changer would be to wean billions off cattle or other inefficient and eco-damaging meats, either with vegetable substitutes like the (yummy) Beyond Burger or else real-meat by tissue culture. Latest: “Memphis Meats, for example, recently filed a patent describing a method to create real chicken and beef tissue using CRISPR.”

Goodyear unveiled its new concept Aero tire, designed to run on roads and double as a propulsion system for flying vehicles.  Yes, the tires become rotors capable of downward thrust and lift. Yipe. Amazing tech.

Optical interferometry has long promised to help us parse distant planets from their hugely brighter nearby stars. Now a group claims to have done it. But then, a few weeks later, we got that image of a real black hole(!) via a method very similar.

 == short takes ==

Methane is so good at trapping heat that one ton of the gas causes 32 times as much warming as one ton of CO2. And Methane is spiking. The possible sources are worrisome. The GOP blocked Obama efforts to fund more inspectors to prevent venting from oil fields. But Trump savagely cut them further and progress toward an international treaty have foundered. 

Even worse are signs that methane is bubbling forth from permafrost and undersea hydrate ices, threatening the “blurp” cascade that would truly make it all deadly, making Earth an almost literal hell. These people are outright enemies of your children.

Slime molds’ ability to reconfigure their volume while fleeing from spots of light has enabled scientists to use these biological computers to solve complex mathematical  conundrums like the Traveling Salesman Problem.

Our opportunity to save ourselves includes ideas like the “Circular Economy.” Watch the video. Then re-read Earth?

An article on Vox discusses the latest silly-wrongheaded attempt by zealots to shout “messages” into the cosmos without ever doing risk analysis or talking it over with the rest of humanity, or allowing their assumptions to be examined. The saddest part is their dislike of science fiction, since SF explores a wide horizon of possibilities, and their religious fanaticism allows for only one.

Wallace’s bee, the size of your thumb and thought extinct, rediscovered!

Evidence that the huge Deccan Traps volcanic eruptions started just before the Yucatan asteroid impact, and hence may have severely weakened the dinosaurs and other species… but then got even worse after the impact, possibly tightening the noose. “The researchers' dates are also consistent with a major shift in the properties of the erupted rock occurring at the same time as the impact. This supports the idea that the impact's seismic effects reached across the entire planet.”

Wired ran a story on Valentine’s Day about OpenAI, the nonprofit institute founded by Elon Musk and Y Combinator founder Sam Altman, which has apparently designed a system that can learn natural language patterns better than any previous attempt so far after feeding it eight million web pages to train it. What is newsworthy to me about this is what they did next: they stopped to consider the implications.  “It could be that someone who has malicious intent would be able to generate high-quality fake news,” an OAI vice president told Wired.

We are a glorious, scientific civilization. Pictures of black holes! SpaceX triple landings! New disease cures! Meat substitutes! And if the enemies of all this want to make this partisan, then let's go.

Altruistic Horizons: Our tribal natures, the 'fear effect' and the end of ideologies

Okay, this is one of my big ones... a major posting about some fundamentals of human nature and history.  I sometimes blog these before posting them as full essays, then chapters in a forthcoming book.  So cinch up your  saddle for a serious ride as we explore some basic drivers of our unique civilization!

----------------------

Social thinkers long yearned for the kind of predictive power offered by universal laws of Galileo, Newton and Einstein -- reductionist rules that changed our relationship with the material world, from helplessness to manipulative skill.

If only similar patterns and laws were found for human nature! Might we construct an ideal society suited to decent living by all? 

Or else... might technologized sociology anchor in the tyranny that almost all our ancestors knew? Tyrannies that were amateurish, by comparison to the coming All-State.

Deep thinkers about human nature start with assumptions. Freud focused on sexual trauma and repression, Marx on the notion that humans combine rational self-interest with inter-class predation. Machiavelli offered scenarios about power relationships. Ayn Rand postulates that the sole legitimate human stance is solipsism. All are a priori suppositions based on limited and personally biased observations rather than any verified fundamental. Each writer "proved" his point with copious anecdotes. But, as Ronald Reagan showed, anecdotes prove nothing about generalities, only about possibilities.

In fact, while the models of Freud, Marx, and Machiavelli (also Madison, Keynes, Hayek, Gandhi etc.) attracted followers, I think a stronger case can be made for 
tribalism as a driver of history. 

Shouldn't any theory of our nature apply across the long span when that nature formed? Indeed, Freud, Marx and Rand shared cluelessness about Darwinian evolution, animal behavior, pre-agricultural anthropology, or ethology.

 Heckfire, shouldn't we be seeking patterns that held across all continents and almost all pre-metal tribes? That are not artifacts of later cultural imposition by contrived societies? The long epoch, when humans were few, but when a vast majority of human generations suffered darwinnowing pressures, thriving or dying according to their fitness to meet challenges in a harsh world, unprotected by the houses and markets and coddling states of the last 5,000 years? 

(And yes, I am qualified to speak here, as a peer-published author in the fields of evolution theory and sociobiology. And in psychology. Well, perhaps not a pro in these fields, but up one small notch. Though let me hurry to add that I will not be talking here about "sociobiology" in the sense that it has long been discussed -- e.g. sexual politics and such.)

THE RELEVANCE OF EVOLUTION

So, what might tribalism tell us about human nature, that was missed by Marx and Freud and Rand etc., in their post-literacy myopia? What traits seem to be shared both by tribal and “civilized” societies?

Over and over, we see how devotion to a group, clan, or nation overwhelms individual self-interest. Indeed, for most of the last million years, any man or woman who lost the faith and confidence of his or her tribe was in great danger. Often effectively dead.

Ask any kid between the ages of ten and nineteen -- how urgently you needed approval of a small group of friends, coincidentally about the same size as a prototypical Cro-Magnon tribal band. And if that group turned on you, remember the pain? 

Sure, parents tell their kids -- "Don't worry, you'll make new friends." At one level, in the rational prefrontal lobes, we know this to be true. And yet, the gut still wrenches, as if life were on the line... which it would have been, back in olden days, if the tribe ejected you from its circle of comradeship. 

Oh, but humans can be very flexible defining what is "my tribe." More often than not, the major determining factor is fear

AND NOW THE KEY POINT: OUR HORIZONS OF WORRY AND HOPE

When the ambient fear level is high, as in civil war-riven Lebanon, loyalties are kept close to home. Me against my brother. My brother and me against our cousins. We and our cousins against the world. Alliances merge and are broken quickly, along a sliding scale that appears to be remarkably consistent.

The general trend seems to be this: the lower the ambient fear level declines, the more broadly a human being appears willing to define those tribal boundaries, and the more generous he or she is willing to be toward the stranger.

Anthropologically speaking, it is "murder" to kill that which is fellow tribesman or citizen (someone identified as inside the tribal horizon). In contrast, it is not murder to kill that which is inherently outside the tribal horizon. (For a cinematic allegory, recall the film "Little Big Man" in which the Cheyenne call themselves the "human beings". And that film was pro-Native American!)

My contention is simple, that there exists an inverse correlation between ambient fear levels and the distance -- in terms of space, time and kinship -- of the "horizons” maintained by average members of a given culture.

These horizons come in several varieties. 

1) There is a "Worry Horizon"... what threats concern you and your neighbors. Here we see that worry is quite a different thing than Fear! The average modern American probably worries as much or more than tribal peoples did! Worry will never go away since it seems embedded into our nature. If immediate needs and threats are dissipated, that only shifts the locus of worry somewhere else, depending to some extent on individual personality. 

But fear is another matter. Fear controls what it is that we are worrying about. And how far we'll look for it.

2) There is also a “Time Horizon” having to do with how far into the future you devote your attention – either in dealing with threats or seeking opportunities. If your children are starving, you are more concerned with the next meal than with the next harvest. 

If the harvest looks okay, you turn your thoughts to longer range matters. Storage, trade, capital improvements… or whether slow loss of topsoil may affect your heirs 200 years from now. The specific topic of your fretfulness may be so extended and abstract (e.g. climate change) that your starving ancestors would find it ludicrous...

...but they would well-understand the buckled brow and dour frowns of concern on your face. The better, more productive and secure civilization those ancestors bequeathed to you did not end all worrying. It simply empowers you to look farther, to more distant, dangerous horizons.

3) Another might be called the "Otherness Horizon” - where one looks not for danger but for opportunities, adventures, new allies, new mating partners. This is also, in anthropological circles, discussed under "exogamy". Clearly, this is one of the reasons early science fiction tales seemed so obsessed with sexy aliens! While the Threat Horizon has been filled with nasty ones. (See my book Otherness.)

This could also be called the “Horizon of Inclusion” since it is partly about deciding how many people you want to deal with as worthy fellow citizens and negotiating partners, and where you draw the line, calling others foes. 

What seems clear, examining historical records and a broad range of cultures, is that all of these horizons expand and contract in the manner described above. The amount of worry may remain relatively inelastic -- a trait of personality, rather than conditions. But the topic of worry changes dramatically and flexibly. Yes, the horizon distance can be affected partly by cultural memes and personality. But overall, these horizons seem to depend most upon the ambient level of fear

OUR FAVORED (OR WEIRD) MODERN PERSPECTIVE

By these lights, most contemporary Americans live in an unprecedented society, where the vast majority of families have not known starvation or even significant want for so many generations that those kinds of worry are almost abstractions. 

This, in turn, has allowed traditional tribal bounds to relax and spread so far that "tolerance" and "diversity" and "otherness" are words of totemic power in this culture! Indeed, it is interesting to view the expanding circle of citizenship and inclusion as first the American colonies and then the Republic began experiencing unprecedented levels of prosperity and fear-reduction. The battles over inclusion that were fought in each generation (first against class division, then slavery, sexism, religious intolerance, racism…) tend to seem obvious to their children, who grow up within the newly-widened horizon set… then wrestle with the next stage. Continuing the process of widening the circle.

While horrific injustices remain, and substantial fractions of the population appear unwilling to let go of their prejudices, there is at least as large a portion of modern citizenry which seems eager to extend the trend of expanding inclusion and empowerment farther still.

I have some accompanying charts, showing a set of nested CYLINDERS, each holding the same volume of worry and optimistic hope. But some are tall and slim, representing societies in which fear levels are very high… and the resulting radius of horizons (threat, time, opportunity and inclusion) are therefore very short range. 

Other cylinders are low and fat, representing cultures wherein fear has been so low, for so long that the horizons of worry stretch very far from the individual worrier, who now obsesses over matters that lie years, or thousands of miles away, and matters of inclusion that involve people (even animals and ecosystems) that his or her ancestors would have simply considered prey. 

Ponder this allegory! You are in a crowd of people -- perhaps in a lecture hall or at a party -- and someone rushes in shouting that "there are whales stranded on the beach!"  (Assume you live near a beach.) 

What then is your reaction? While some might shrug at the news, I figure you and many of your friends would drop everything and hurry toward that beach, as fast as you can...

... which is exactly the same thing your ancestors would have done, upon hearing the same news.

Only consider. Your ancestors would be rushing to the beach with different intent. You are propelled by eagerness to help-the-included-other. 

Your forebears' race to the shore would be propelled by one word, foremost in their minds.

Lunch.

== Fluctuating boundaries ==

Ponder that allegory of the beached whales. You know it to be true. So? Were your ancestors cruelly benighted folk? Implying that you are a tremendously more elevated being than they were? 

Hm. Elevated, perhaps you are. But only because those ancestors strove to create conditions under which you cannot imagine needing whale meat to feed your starving kids.  Instead -- more relaxed -- you assign whales within the circle of inclusion. To your eyes, they are fellow citizens meriting generosity, protection and respect.

Today we discuss threats and opportunities in terms of a century or more, with asteroids and Mars colonies and melting icecaps open for serious discussion. Inclusion arguments now extend to legal rights for animals. Indeed, the process of inclusion expansion has been reinforced!  Not only with supportive propaganda (tolerance-diversity memes in every children's book and Hollywood flick), but also via the hard-won lesson of practical economics -- that it is simply stupid to waste talent. A waste that is the principal cost of prejudice.

Yes, fashionable horizon/inclusion issues can fluctuate at the boundaries. Note how nationalist patriotism was considered an archaic and rather quaint viewpoint in the 1990s, till an uptick in fear after 9/11 caused a partial contraction of horizons for many. Suddenly, flags were all the rage. (We'll get into how this process affects modern politics.)

And yet, it is a sign of this culture’s deeper confidence that our horizons of inclusion have not appreciably contracted. Today -- especially in certain western nations -- we give a kind of culturally-based honorary citizenship to dolphins and consider it murder to kill as alien a creature as a whale. 

Science fiction thrives in such a culture, since it brashly extends horizons in both time and space as far as human imagination can take us. 

The threat horizon is occupied by vicious invader-aliens and the exogamy horizon by beautiful ones... and the inclusion horizon finger-wags that non-murderous aliens merit nurturing protection from our own, freely-elected government! Heck, did you see District 9? They don't even have to be attractive anymore, to merit protective inclusion.

Of course the macro topic here could be oversimplified as “altruism,” since that, too, is about extending beneficence to the other. Altruism is receiving a fair amount of attention, of-late; see three new books on the topic reviewed here by Scientific American.  And the cogent volume Pathological Altruism, edited by Barbara Oakley et al., containing two papers by yours truly. Though our topic here -- horizon expansion -- is about much more, since altruism is just one of many zones across which we stare at the other. 

== Variation ==

It is important to note, of course, that our cylinder-charts only depict a rough average. Within any culture there will be many individuals whose fear levels - or personal ways of responding to fear - are quite different from the surrounding norm. Indeed, these variations are what we tend to notice from day to day. Certainly Timothy McVeigh had very different concepts of "inclusion horizons" than many of the fellow citizens he slew.

Indeed, might one diagnose some recent phenomena in these terms? Why is it that citizens of New York and Washington DC – direct victims of 9/11 terrorism – remain utterly “blue” in their fealty to expanded horizons – in time, threat and inclusion – while “red state” attitudes seem to draw closer in: e.g. higher enmity toward non-natives and immigrants, less concern about environmental degradation, more hostile ruminations over “war” on terror, less interest in science and more in a pending, biblically-ordained end of the world? 

Is this model the best one, yet, at explaining such differences? Certainly it is far better than any insipid “left-right political axis” or words such as “conservatism” and “liberalism.”

Also, different cultures will react to prosperity and peace in markedly different ways. I believe it will take many generations of tranquility and progress before the deeply ingrained Russian proclivity toward paranoia and pessimistic gloom will be forced to give way to a cheerier mien. Likewise, so long as most children in the Middle East are raised with fairy tales that preach revenge as a high human value, horizon-widening will at best be a jerky process. Skim 1001 Arabian Nights and tally the few tales that don't involve revenge. Indeed, much the same can be said of older western myths, collected in Grimm's Fairy Tales. The counter-push by tolerance messages - e.g. Hiawatha and Sesame Street - is recent! 

Indeed, cultural variation can be seen even within the U.S., as those with more "confederate" upbringing react with hackles toward diversity preachers. They deem those who push relentless horizon expansion to be sick persons... and vice-versa. Or else, look at the divide within the SF community, with fantasy writers and readers much more willing to dive into old-fashioned romanticism, in which whole classes of beings (orcs, zombies, clone-stormtroopers) deserve - by their very nature - to be annihilated. Are the relentlessly feudal settings, featuring states of bone-chilling fear, tools to resurrect that delicious us-versus-them feeling, letting fans enjoy intolerant slaughter guilt-free?

Peering in the opposite direction: what happens when fear goes to zero? Do we get infinite horizons? I suspect that there is more than a little religious writing on this subject. Indeed, might this be the purely detached compassion that is written about in Buddhism? Is it one of many traits we must achieve, before deserving to become members of an interstellar federation? 

Or else apprentices in the Workshop of Creation?

CAN WE KEEP WIDENING HORIZONS?

No mistake, I approve of this trend toward ever-widening horizons. (Which may be the deep underpinning of science fiction, by the way. Watch this TED talk where I explore in-depth.) 

Indeed, like millions of others, I am impatient for it to go much farther. It is ironic, though, how few seem to realize that the new era of Omni-Inclusion is based upon prosperity and lack of fear brought on by prosperity, and that our morality of universal tolerance would have been considered terminally sappy and dangerous by every other culture in human history.

This is – in my view – the deepest smug insanity of the "left."

 Yes, the “right” obviously suffers from shorter horizons. That is their dire craziness. But the doctrinaire left is just as loopy. Because they take expanded horizons as a deeply fundamental ‘given’ of human morality. Like Rousseau, they simply assume, as something basic, a value system that is actually extremely recent and entirely contingent. One that is based upon unprecedented levels of wealth and satiation. 

Indeed, were they to preach this doctrine of hyper-tolerance to any of the ancient “wise tribes” that they so revere, they would have been laughed out of camp! 

Can this process be pathological at some level? Jason Cawley wrote: "There is such a thing, comical as it sounds, as a Gaia Liberation Front. They have decided that mankind is dangerous to life on Earth. They have given up on warnings preventing eco-catastrophe, have passed the stage of welcoming die-backs to hunter-gatherer existence, have realized that capitalistic assaults on nature are a programmed possibility of man, revealing therefore man as a form of cancer within life, and have decided this applies even to "indigenous peoples" because they might develop technology someday. Because of that whole chain, they have decided that mankind must be wiped out before life is. They only debate how to do it. The public relations position is voluntary mass suicide, but among themselves they are more direct and pin their hopes on an engineered virus, airborne and lethal to humans, which they propose to make before anyone else learns and uses enough biotech to screw up the planet."  (See this point of view garishly illustrated in a very silly and occasionally outright offensive flick: "Kingsman.")

Summarizing: Today's political camps might be typified by how they feel about the process of ongoing horizon expansion.

 "Leftists" give the process itself their utter and devoted loyalty.  The next inclusion push is the be-all of obsession, and to hell with older loyalties.  

People on the "right" react with hackles: "I like my old loyalties, so stop nagging me!"

Liberals, the sole group who think positive-sum, like the horizon expansion process... but liberals also like many of their older loyalties, and see no reason why they should have to choose. 

Again, this has nothing to do with classic, Marxian "left-right". Rather, it posits that today's tussles are matters of personality! A suggestion borne out by the research of Jonathan Haidt.

FORGET ROUSSEAU. FORGET HOBBES. 

And forget Marx, Freud and Rand, for that matter. If one takes history into account and cheerfully accepts the incremental progress that it portrays, then the Modernist Agenda of pragmatic improvement makes a great deal of sense. Face it. Rousseau was a sap and Hobbes was a suck-up grouch. All of this is about Locke. The sooner the “wide-horizons” people realize it, the more effective they will be at pursuing their agenda, of expanding inclusion ever farther!

In fact, this process of horizon-widening is not intrinsically a feature of the left… though it is intrinsic to liberalism in the older and truer meaning of the word. It is utterly compatible with the four accountability arenas, for example (science, markets, democracy, courts… and the candidate for becoming a fifth arena – the internet. (And a sixth -- Sports.)

For example, markets work best when competition is both encouraged and well-regulated… when it operates under rules of fair play that maximize creativity and minimize blood-on-the-floor. This can only happen when market participants must treat each other as competing teams, not deadly foes. 

Indeed, one of the major outgrowths of our unprecedented experiment in universal citizenship has been a fundamental change in the shape of the modern social structure.  Society as diamond, and not pyramid, is partly a product of technology (making a new class of slaves called "machines", to occupy the lowermost tier), but also a result of having trained several generations of children to think in terms of non-zero sum games. But more on that anon. 

Hence, once again, we see that this is not a matter best handled on a 'left-right' basis. Both dogmatic extremes ignore history and are effectively quite mad! One side resists the widening of horizons while the other would force it with a patronizing, oversimplifying sledge hammer.

Rather, this is about the true “liberal” notion of ever-increasing inclusion within the tent of human decency - motivated in part by the pragmatic need to stop wasting talent through prejudice - while allowing a lot of give and negotiation and bickering and creative competition inside the tent! 

PUZZLERS

There are many questions. For example - can the long process of expanding human horizons be studied in order to determine crucial narrow points and bottlenecks that inhibit horizon broadening, among both individuals and cultures? 

If such bottlenecks can be found and diagnosed, might a judicious application of philanthropic funding help unblock the process, here and overseas, so that both tolerance and far-seeing investment practices take greater hold?

Some societies on Earth have had plenty to eat for a while, yet have not taken as readily to horizon expansion... especially the horizon of inclusion. Hence, to what degree does culture play a significant role?  Might it be that humans only become satiated enough to extend those horizons, when they have been taught first to be at least somewhat satiable?

Is science fiction an artifact of horizon expansion? Certainly what you and I call the real stuff has to be. But recall that there were always tales of the fantastic, all the way back to tribal eras, and these helped reinforce horizon walls. Indeed, nothing could be more romantic and more savagely non-inclusive than most modern fantasy tales, in which the slaughter of every orc, or imperial clone trooper, is just fine, under the presumption that their type has no mothers to mourn them.

Do I deem my "horizons" model of human nature to be as valid as Marx and Freud and Rand declared theirs to be? Of course not. It is a model. Models are only memes and tools, not the things that they emulate!  I can only say that those other social theorists made no effort to span the tribal era that made us, nor to explain the pervasiveness of feudalism.

But the tradeoff between FEAR and the distance toward which we peer... that seems to be eternal.

There is no end to questions. That's a good thing! A feature of our process of horizon examination, not a flaw. 

And with that, I will now back away. Maybe put some of this into a story.

Though in fact, the core issues of "otherness" have been the central focus of my life.
