It is always a cheery thing to reflect on the fact that humans are not currently fitted with shock collars.
As a crowd masses at an international border, pressing up against the gateway to a purportedly safer country, held at bay by armed guards, yet another stream of refugees fleeing from some armed conflict over differing versions of reality, a hawk flies over the crowd and enters the airspace of the safe country. It has violated the airspace, yet no passport was presented, no fighter jets scrambled, no shots were fired, and nobody was led away in leg irons to a holding cell. The hawk disappears over the ridge. Say goodbye.
Zoologists will fit animals with radio collars to monitor their movements. Pet owners will fit dogs with shock collars to prevent them from traveling into a restricted area, like the neighbor's garbage can. Police will fit errant humans with ankle bracelets to monitor their movements and prevent them from traveling into a restricted area, like Shorty's Tavern. Yet, we see no herds of migrating humans outfitted with shock collars.
Incidentally, despite the short step from ankle bracelet to shock collar, most humans willingly fit themselves with cellular phones that monitor their movements. While our data is liberated from our accounts and pored over by men in trenchcoats with thick accents, we are deterred from entering actual locations and relationships. Don't walk on the neighbor's grass. Don't talk to the person next to you on the bus. Keep focused on the flat screen. Something follows this. We have all found out that the buzzing in the coat pocket often precedes an intense episode of humiliating interrogation by some older relative or salesperson. This is called conditioning. Do not imagine what is next.
Now, as noted, the restricted areas are often imaginary lines, ones invisible to sentient beings, with the clear exception of us wayward humans, who have the unique ability to perceive things that don't really exist and to wage war with those who perceive a conflicting unreality. This battle over unrealities is called the March of History. It is the unenviable load of historians to attempt to describe what is not actually there in such a way that the reader segregates it from fiction. This is unsustainable. This is why most history books are ephemeral, like a shimmering mirage in Death Valley, filled with the bones of millions of men and women who crawled across the sand convinced that it was a real freshwater lake filled with real schools of promise. Enter the next dynasty, the one with a conflicting version of unreality, and the books are revised, banned, or burned. A new mirage appears and another crowd forms on the imaginary shoreline.
The fences in the field create fences in the mind. Thoughts in isolation do not thrive; this is not an original thought. It's like the ghost image of our schoolteacher that appeared when we closed our eyes after staring at her standing in front of a black chalkboard for 20 minutes. Life reproduces phantom life in the mind.
Here is a paradox: inbreeding depression is the effect seen when a population becomes isolated and breeds with closely related individuals. They become unfit, less likely to survive. Thus, if children had been segregated according to hair color, while we would experience no suprise if blondes were to wage war with brunettes in the near term, in the long term, after several generations of blondes interbreeding with blondes and brunettes interbreeding with brunettes, we would expect bad traits to arise, an upwelling of deleterious characteristics. Sloped foreheads, brow ridges, palm hair, whippy little tails, and a host of deleted or duplicated parts like extra sets of legs, cartoon hands, or the proverbial Third Eye.
Dagnabbit, this keyboard is too small for all these fingers.
At the same time, isolation of populations is said to drive what is called speciation, the creation of new species, which develop traits and reproductive behavior that renders them incompatible with their parent population. Think leopards and jaguars, dingos and coyotes.
Don't get too excited. Looming over all of this is the March of Science, in which the scientific method seeks to establish a more perfect conception of reality. Michaelangelo once stated, "The sculpture is already complete within the marble block, before I start my work. It is already there, I just have to chisel away the superfluous material." That is art, that is science. The hard truth at the center may be: we are still in the quarrying phase.
Despite the provisional status of ideologies, angry crowds full of assumption push to the front of the line. If variety arises from isolation while isolation creates unfit varieties, the question arises, What happens to us? Better check your watch. There is a huge mob forming at every international border and each side perceives the other side to have deleterious characteristics - their shape, color, language, gestures, height, weight, the way they laugh, the way they greet, the way they think.
Militias arrive with truckloads of shock collars. Say goodbye.
