Britain AD: The Invasion That Never Was – The Anglo-Saxon Invasion (BBC Documentary)
Johnny66
Published 21 Jun 2015A well-considered documentary by the noted scholar, Dr Francis Pryor. The names Cerdic, Ceawlin, Cedda and Caedwalla are not exactly Germanic in origin? Cerdic’s father, Elesa, has been identified by some scholars with the Romano-Briton Elasius, the “chief of the region,” met by Germanus of Auxerre.
Cultural factors in the spread of the Wuhan Coronavirus
Sarah Hoyt explains why any computer model involving actual human beings might as well begin with “Assume a Spherical Cow of Uniform Density in a Frictionless Vacuum“:
What I do know is that — are you ready? — human societies, involving multiple nations or even our own culturally diverse, geographically spread out nation, are not now nor will they ever be a spherical cow of uniform density in friction-less vacuum.
So … why is it that even now that they admit the scary Imperial model is insane, our authorities, from federal on down are treating the US as though it were just that mythical cow, and on top of that exactly the same as the cow in Italy, Spain or France.
[…] but here’s the thing: Italy has a completely different culture. Yes, it also has a sclerotic, understaffed and just impoverished healthcare system. (Yes, every time I post that I have to spam a million comments telling me how well the WHO ranked Italy — which is great, except the WHO ranks a single payer system above everything else, including outcomes — and how Lombardy is the envy of Italy or something, which leads me to say “Sucks to be you.”)
However, that’s just a factor in the debacle. The other factor is culture and no one is taking it into account. Multi-generational families live together (I should throw stones, yes) or in the same house which becomes a sort of compound. (This is common to all Mediterranean cultures. I grew up in such a compound until the age of six.) which means that while Grandma isn’t abandoned to the tender mercies of Haitian health workers, it’s also really hard to isolate her when little Guido gets the never-get-well at school and cheerfully brings it home. Even when they don’t live together, extended families have a level of closeness that freaks out even the closest American families. If you and your relatives live within driving distance of each other and don’t see each other every other day, there’s something wrong.
Every house is a continuous cacophony of visiting relatives and friends. In safer times, we just left the back door unlocked because it was easier than answering the doorbell every five minutes. When I first got married, I had the TV on all day, because otherwise the house was so silent, it freaked me out. (I left Disney channel on all day, because it was less likely to startle me with explosions or evil laughter. This led my inlaws to believe I only understood “English for children” (rolls eyes.) I wasn’t even in the room with it. I just needed that noise, or I freaked out, because of the habit of a lifetime.
The freakiest thing in my exchange student years was that my family never had people drop by, several times a week, just because.
On top of that, of course, a lot of the younger people live in stack-a-prole apartments with shared air, and most people commute by train or bus or something.
Now, in Portugal at least most trains and buses aren’t as full as they were in my youth. You are rarely packed in like sardines. But it’s still public transport, and at rush hour every seat is taken and there are people standing.
As much as I get sick here, I got sick way more often there, and had a few really close calls, starting at about thirteen. Because you live in each other’s pockets.
And I understand that in Italy, as in Portugal, as in, for instance, France, people kiss a lot more. Adult men might not, unless they’re close(ish) relatives, but women and children get kissed by everyone from close kin to total strangers.
All of those create conditions for the virus to explode. In Italy, in France, in Spain. I understand it’s not exploded nearly as much in Portugal, but I also wonder how much of that is Portuguese reluctance to go to the doctor or the hospital. Because “the hospital is where you die.” (Yes, sue me. Some cultural assumptions remain. Which is why my husband is the one who normally drags me to the hospital.) Because, you see, we DO know for at least one of the clusters, the hospital was making it worse. Go to the hospital for any other reason, catch Winnie the Flu.
QotD: The universal plight of women in pre-modern times
Because giving birth was such a high-risk enterprise, and because so many of the products of that enterprise died before payback of the [pun intended, I think] labor involved in bringing them to the world, it was THE most important work of society. Those members able to do it had to be kept in such a situation that it allowed them to maximize that one thing they could do.
As for “the property of their husbands, etc, etc, blah blah blah” work was so brutal and hard, and providing for a family so difficult, that yes, a man wanted to make sure the children he supported were his own.
Also, because of very early (many women married before even 18) death in childbirth, etc, most women skewed younger than men as a population, which would encourage a certain degree of paternalism. On top of that, hate to tell you, but women while hormonal are often not fully rational. We can sort of compensate for it, but one of the pregnancy hormones is SUPPOSED to make you fat, dumb and happy.
I don’t know if most women need a minder while pregnant, but from both personal experience and watching friends go through it, I imagine many women do.
It is therefore only natural that in a society where most women are pregnant most of the time, men would view it was their duty to look after the puir confused things.
When feminists assume that back in a time with no contraceptive, high child mortality and an horrendous death toll of pregnancy, women should have been recognized as the equals of men, and that men were being evil villains for not doing that, they are demonstrating an astonishingly blind and ideological view of history.
In fact, even back in the middle ages and before SOME women were considered the intellectual equals of men. (And sometimes the military equals.) There are very few of them, again, not because The Man was keeping them down, but because the women attracted to intellectual or military pursuits are (like men) a minority and on top of that they tended to be either unmarried, childless, or the percentage of women not much affected by pregnancy. I.e. a minority of minorities.
Women started making advances in what was considered, traditionally, male realms, like science or scholarship, (the others … well … there is a problem with upper body strength. Sure. Some women. Again a minority of a minority) or being able to vote when two twin advances occurred: the first was the curbing of infant mortality. When it became obvious (after a generation or so) that most of your babies would survive, it was possible for women to spend only a tiny minority of their lives pregnant.
The second was contraception that was cheap, easily available, and safe. Yeah, okay, I have certain issues with the pill, because the medical issues of using it long term are only now showing up in the population at large. That’s fine.
It remains that even the early “horse-dose” pill was safer than anything else anyone else had ever come up with for women to avoid getting pregnant all the time.

Eighteenth century health improvements through “ventilators”
In the latest Age of Invention newsletter, Anton Howes relates how a mistaken belief still led to a significant improvement in health:
One of the most worrying diseases of the mid-eighteenth century was typhus. We now know that it is spread by lice or fleas, but at the time, like so many other diseases, it was thought to be caused by noxious air — “malaria”, for example, literally means “bad air”. This was not a silly theory. It was based on empirical observation, which perhaps explains why the belief in such noxious miasmas persisted for so long — well into the late nineteenth century, if not the early twentieth, before finally being ousted by germ theory. Our ancestors were not stupid, no matter how strange their beliefs might appear in hindsight. (Also take alchemy, or the belief that some animals spontaneously generated.)
The Central Tower of the Palace of Westminster is actually a disguised ventilator.
Photo by Cary Bass via Wikimedia Commons.Typhus fit the miasma theory especially well because it frequently appeared in confined spaces, like ships’ holds, prisons, mines, workhouses, and hospitals. The disease was thus often called “gaol fever”, or “hospital fever”. And there was the fact that at least one of the solutions designed to combat miasmas, the ventilator, actually seemed to work. This ventilator was not the kind that is in such high demand right now, used to help feed oxygen into patients’ lungs, but instead a machine used to get the air flowing in and out of confined spaces — like a 1740s air-conditioning unit.
At first glance, removing the stale air from a space shouldn’t do anything against typhus. But mortality declined drastically in the prisons and ships to which the ventilator was introduced. It halved the number of deaths per year in Newgate prison, where the bellows-like machinery was powered by a windmill, and the inmates of the Savoy prison fared even better. On ships, too, mortality declined among mariners, passengers, soldiers, and especially among the group that suffered most from long voyages across the eighteenth-century Atlantic: slaves.
But it’s not clear exactly why. After all, the ventilator did not kill the typhus-ridden lice or fleas. I have a few theories as to what must have been going on. Perhaps, by improving the supply of oxygen to confined spaces, people’s bodies were simply better served to deal with all manner of diseases. Surgeons aboard slave ships sometimes noted that, without proper ventilation, many slaves would simply die in the night of suffocation. Or perhaps the ventilator’s effectiveness had something to do with its drying effect. The machine was used to prevent grain stores from becoming humid, thus staving off damp-loving weevils. The ventilators might thus have staved off typhus through a similar means: although I’m not so certain about body lice, humid conditions are preferred by fleas. Regardless of the real reasons, the ventilators worked, and even when they did not reduce mortality, they made confined spaces more bearable for those who had to endure them. Ship captains reported that they did not even have to force their sailors to pump the ventilator’s bellows, because they liked the cool air so much. Ventilators were soon installed in the House of Commons, and in many of London’s theatres.
From the Wikipedia entry on architectural ventilation:
The development of forced ventilation was spurred by the common belief in the late 18th and early 19th century in the miasma theory of disease, where stagnant ‘airs’ were thought to spread illness. An early method of ventilation was the use of a ventilating fire near an air vent which would forcibly cause the air in the building to circulate. English engineer John Theophilus Desaguliers provided an early example of this, when he installed ventilating fires in the air tubes on the roof of the House of Commons. Starting with the Covent Garden Theatre, gas burning chandeliers on the ceiling were often specially designed to perform a ventilating role.
Mechanical systems
A more sophisticated system involving the use of mechanical equipment to circulate the air was developed in the mid 19th century. A basic system of bellows was put in place to ventilate Newgate Prison and outlying buildings, by the engineer Stephen Hales in the mid-1700s. The problem with these early devices was that they required constant human labour to operate. David Boswell Reid was called to testify before a Parliamentary committee on proposed architectural designs for the new House of Commons, after the old one burned down in a fire in 1834. In January 1840 Reid was appointed by the committee for the House of Lords dealing with the construction of the replacement for the Houses of Parliament. The post was in the capacity of ventilation engineer, in effect; and with its creation there began a long series of quarrels between Reid and Charles Barry, the architect.Reid advocated the installation of a very advanced ventilation system in the new House. His design had air being drawn into an underground chamber, where it would undergo either heating or cooling. It would then ascend into the chamber through thousands of small holes drilled into the floor, and would be extracted through the ceiling by a special ventilation fire within a great stack.
Reid’s reputation was made by his work in Westminster.

Sensible risk management is not compatible with the “precautionary principle”
David Zaruk wrote last week for Science 2.0 Europe:
Two decades of the precautionary principle as the key policy tool for managing uncertainties has neutered risk management capacities by offering, as the only approach, the systematic removal of any exposure to any hazard. As the risk-averse precautionary mindset cements itself, more and more of us have become passive docilians waiting to be nannied. We no longer trust and are no longer trusted with risk-benefit choices as we are channelled down over-engineered preventative paths. While it is important to reduce exposure to risks, our excessively-protective risk managers have, in their zeal, removed our capacity to manage risks ourselves. Precaution over information, safety over autonomy, dictation over accountability.
- Whatever happened to “Keep out of reach of children”? Now we cannot be trusted and all products must be child-safe.
- Whatever happened to “Handle with care”? Now safety by design has removed the need for individuals to exercise common sense or risk reduction measures.
- Whatever happened to trust? Now individuals are no longer left with the capacity to make their own decisions in managing personal risks.
“These are good things” precaution advocates would retort “since people often make mistakes and bad things can better be prevented!”. While continuous improvement of safety systems has its value, the bigger the fences, the less autonomously the individuals will react (creating a society of docile followers). The precautionary approach implies a lack of trust in individuals’ capacities to make their own (rational) choices. The over-engineered risk-management process would remove any situation where choices could be made. Fine for cases where there are no trade-offs, disruptions or loss of benefits (when the sheep have plenty of grass in their field), but in times of crisis (exposure to hazards), when precaution is your only tool, then sacrifice is the only solution.
[…]
When the public now sees everything of modern life (work, school, public events …) cancelled in a knee-jerk precautionary impulse, is it any wonder they are panicking? Enter the opportunist to sell you the silver solution or the naturopath detox remedy to put your mind at ease. Enter the quack to tell you to drink bleach. Enter the racist who will use the fear to mobilise outrage. Exit rationality and risk management.
With no bullets left in the risk-management gun, the only thing left to do is run … or as it is more commonly called: apply the precautionary principle. Precaution should only be applied after other risk management measures have failed but given how horribly inadequate our capacities to govern have become, it is the only strategy our regulators have come to know.

What is really driving the Wuhan Coronavirus panic
… besides the wall-to-wall hysteria in the mainstream media, I mean. Severian discusses the insights of “perverted old cokehead” Sigmund Freud on anxiety and its effects, then segues to our current, shared, plight:

Photographic portrait of Sigmund Freud, signed by the sitter (“Prof. Sigmund Freud”) by Max Halberstadt (c. 1921)

Everyone who has thought about it for five minutes knows that something’s not right. […] As y’all have noted, actual hard information on the coronavirus is hard to come by. Is it fully air-transmissible? What are the infection rates? Hell, what are the death totals? And speaking of the death totals, even if you trust China’s figures (which no reasonable person can possibly do), they seem … low. Like, really low. I actually trust Italy’s government to deliver some vague approximation of the truth, and even there, where they’re in full-blown freakout mode, it seems to kill off old folks with compromised immune systems and lung problems at a fractionally higher rate than your garden-variety flu.
So, you know … it’s the flu. Not great by any means, and more infectious (possibly) than some other flus in our recent past, but for all that just the flu. The ongoing sky-is-falling global freakout has next to nothing to do with the actual bug. We live in a deeply anxious age, and that anxiety has to discharge somehow. It’s global hysteria — classic hysteria, Freudian hysteria, an excess of stress that must be discharged by “converting” it into behavior.
The people who are freaking out about it aren’t worried about dying from it. No, really, they’re not. Nor should they be — no reasonably healthy person under age 70 has any reason to be worried about that. Instead, what they’re worried about is powerlessness. We’ve all long suspected that we’re ruled by idiots and grifters. We’ve all long sensed that our “leaders” hold us in deep contempt. And we’ve long known that none of our problems are worth anything to the global pirate capitalist class. The only reason those bastards care if we all drop dead from the plague is that they can’t sell enough iCrap to each other to keep the company stock price up.
We know this. But we can’t say it, and we can’t act on it, because doing so goes against our self-image. Our media, our education system, our “culture” (such as it is) has spent the last half-century telling us what special and unique snowflakes we all are, even as it’s forcing us into ever-greater conformity. We’ve broken all the taboos, transgressed all the boundaries, liberated all the oppressed. If there ever were to be such a thing as “social justice,” then truly we’ve achieved it, here in this best of all possible worlds where you can lose your job for not addressing your co-worker as a wingless golden-skinned dragonkin and 6’2″ dudes with beards down to their collarbones can go wee-wee in the little girls’ room …
… and yet. And yet. And yet feminists (just to stick with a theme), despite running everything for the last 30 years, still can’t get that lousy 25 cent raise. Seven out of every five college girls are sexually assaulted the minute they step on campus, despite boys being as rare as sasquatches on most campuses (and despite the ever-growing clamor for free college for everyone). You’re free to — hell, you’re practically required to — make up your own pronouns, but you’re not allowed to ask just how a degree in “gender studies” could be worth even one dollar in student loan debt, let alone one hundred thousand dollars. We keep agitating for change, keep voting for it, keep tweeting about it … and nothing happens.
That profound sense of powerlessness is exactly, and I do mean exactly, what screwed up Anna O. She hated her father for not allowing her any personal agency. In her heart of hearts she wanted him dead. And yet she knew herself to be a loving daughter, so that overwhelming sense of relief — indeed, of joy — she felt when he kicked the bucket sent her around the bend.
A classic “dirty book” of the late Middle Ages
I’m not well read in the classics, being much more of a history reader myself, so I didn’t know anything about The Decameron. Arthur Chrenkoff provides a helpful thumbnail of the book:

“A Tale from the Decameron” by John William Waterhouse (1916).
Image from the Lady Lever Art Gallery via Wikimedia Commons.
Giovanni Boccaccio had written The Decameron in the aftermath of the Black Death pandemic of 1348, which carried away somewhere around one third of the European population. The book is set in a monastery, where seven young women and three young men, the Millennials of the day, self-quarantine themselves for ten days to avoid the plague and while away their days (there was no internet in those days, you see) telling each other stories, ten each day, all based around a chosen theme, such as love that ends happily or the tricks that women play on men. Many of the stories are a bit dirty, which is why The Decameron was put on the Catholic Church’s index of prohibited books; more interestingly, it was also banned in Australia until 1973, on pretty similar grounds.

Cognitive dissonance, family style
Severian has some fun discussing current events with a nephew:

Image from Castle of Chaos – https://castleofchaos.com/blog/5-tips-for-surviving-a-zombie-apocalypse/
Just recently I had some fun with one of my nephews, who’s unexpectedly home for “Spring Break.”
Let’s take this Wuhan Flu thing seriously, I said. But since that hits a little too close to home, let’s pretend it’s a zombie outbreak. I want you to take it 100% seriously. The zombie virus has made it to our shores. It’s not too bad yet, but there’s definitely a walking dead situation. So … what do you want the government to do?
Nephew of course starts rattling off all the Chuck Norris fantasies young college guys have. Close the ports, call out the army, firebomb the streets wherever infected are sighted, yadda yadda. All of this is translated from the teenager, but you get the gist of it:
Me: Ok. Now, since we’ve stipulated that we’re taking this 100% seriously: Do you really want to give the government the power to do all that?
Nephew: Of course!
Me: Ok. Well then, do you really want to give Donald Trump the power to do that?
Nephew: Oh my god no!!! Orange Man bad!!!
Me: Now wait a minute, Nephew. You just said you’re taking this 100% seriously. You just said you want the government to have the power to set up flamethrower checkpoints on all major roads. Well, who is the current head of the government?
Nephew: But … but … but … Orange Man BAD!!!!
Me: Remember, Nephew, you promised to take this 100% seriously. So are you seriously telling me that the first thing you’d do, in the event of the zombie outbreak, is call an emergency presidential election, in the hopes that someone — Joe Biden, Bernie Sanders, Tulsi Gabbard, somebody — would win, so that the right kind of person could take all those measures you said were so very, very, very immediately necessary?
Nephew: Uhhhh … no, I guess not.
Me: So you do want to give Donald Trump that power, since he is, in fact, the current head of the United States government?
Nephew: Oh my god no! Orange Man BAAAAAAADDDD!!!!
Me: Well then I guess you’re just not serious about this zombie outbreak, are you?

QotD: The latest breakthrough in psychological therapy
All therapy books start with a claim that their form of therapy will change everything. Previous forms of therapy have required years or even decades to produce ambiguous results. Our form of therapy can produce total transformation in five to ten sessions! Previous forms of therapy have only helped ameliorate the stress of symptoms. Our form of therapy destroys symptoms at the root!
All psychotherapy books bring up the Dodo Bird Verdict – the observation, confirmed in study after study, that all psychotherapies are about equally good, and the only things that matters are “nonspecific factors” like how much patients like their therapist. Some people might think this suggests our form of therapy will only be about as good as other forms. This, all therapy books agree, would be a foolish and perverse interpretation of these findings. The correct interpretation is that all previous forms of therapy must be equally wrong. The only reason they ever produce good results at all is because sometimes therapists accidentally stumble into using our form of therapy, without even knowing it. Since every form of therapy is about equally likely to stumble into using our form of therapy, every other form is equally good. But now that our form of therapy has been formalized and written up, there is no longer any need to stumble blindly! Everyone can just use our form of therapy all the time, for everything! Nobody has ever done a study of our form of therapy. But when they do, it’s going to be amazing! Nobody has even invented numbers high enough to express how big the effect size of our form of therapy is going to be!
Consider the case of Bob. Bob had some standard-issue psychological problem. He had been in and out of therapy for years, tried dozens of different medications, none of them had helped at all. Then he decided to try our form of therapy. In his first session, the therapist asked him “Have you ever considered that your problems might be because of [the kind of thing our form of therapy says all problems are because of]?” Bob started laughing and crying simultaneously, eventually breaking into a convulsive fit. After three minutes, he recovered and proceeded to tell a story of how [everything in his life was exactly in accordance with our form of therapy’s predictions] and he had always reacted by [doing exactly the kind of thing our form of therapy predicts that he would]. Now that all of this was out in consciousness, he no longer felt any desire to have psychological problems. In a followup session two weeks later, the therapist confirmed that he no longer had any psychological problems, and had become the CEO of a Fortune 500 company and a renowned pentathlete.
Not every case goes this smoothly. Consider the case of Sarah. Sarah also has some standard-issue psychological problem. She had also been in and out of therapy for years, tried dozens of different medications, none of them had helped at all. Then she decided to try our form of therapy. In her first session, the therapist asked her “Have you ever considered that your problems might be because of [the kind of thing our form of therapy says all problems are because of]?” Sarah said “No, I don’t think they are.” The therapist asked “Are you sure you’re not just repressing the fact that they totally definitely are, for sure?” As soon as Sarah heard this, she gasped, and her eyes seemed to light up with an inner fire. Then she proceeded to tell a story of how [everything in her life was exactly in accordance with our form of therapy’s predictions] and she had always reacted by [doing exactly the kind of thing our form of therapy predicts that she would], only she was repressing this because she was scared of how powerful she would be if she recovered. Now that all of this was out in consciousness, she no longer felt any desire to have psychological problems. In a followup session two weeks later, the therapist confirmed that she no longer had any psychological problems, and had become the hand-picked successor to the Dalai Lama and the mother of five healthy children.
Previous forms of therapy have failed because they were ungrounded. They were ridiculous mental castles built in the clouds by armchair speculators. But our form of therapy is based on hard science! For example, it probably acts on synapses or the hippocampus or something. Here are three neuroscience papers which vaguely remind us of our form of therapy. One day, neuroscience will catch up to us and realize that the principles of our form of therapy are the principles that govern the organization of the entire brain – if not all of multicellular life.
