That sounds exciting. I'm looking forward to seeing this and I will hold you to your prediction. 2030 ain't far out.


Indeed. And then we can discuss the definition of "interesting", couldn't we? :-D

That is very debatable. I think it greatly depend on the type of disaster.

Yes - I already said that.

If there's complete destruction (nuclear) or other gross environmental degradation, the situation is probably much different.

Obviously - and I already conceded that - both on my blog and in this chat.

Keep in mind that the medievel ages didn't pick up the pieces from the romans.

It depends on what you mean. They might not have had the same nationalistic empire building successes, but that hardly means they descended into barbarism and anarchy. There was structure and learning and even development in some areas. There's a lot of cultural baggage around the "Dark" and Medieval ages that we all inherit from probably the most successful and longest lasting bit of propaganda ever.

The concept of a "Dark Age" originated in the 1330s with the Italian scholar Petrarch, who regarded the post-Roman centuries as "dark" compared to the "light" of classical antiquity.[1][2] The term employs traditional light-versus-darkness imagery to contrast the era's "darkness" (lack of records) with earlier and later periods of "light" (abundance of records).[1] The phrase "Dark Age" itself derives from the Latin saeculum obscurum, originally applied by Caesar Baronius in 1602 when he referred to a tumultuous period in the 10th and 11th centuries.[3][4] The concept thus came to characterize the entire Middle Ages as a time of intellectual darkness in Europe between the fall of Rome and the Renaissance. This became especially popular during the 18th-century Age of Enlightenment.[1]

As the accomplishments of the era came to be better understood in the 19th and 20th centuries, scholars began restricting the "Dark Ages" appellation to the Early Middle Ages (c. 5th–10th century),[1][5][6] and now scholars also reject its usage in this period.[7] The majority of modern scholars avoid the term altogether due to its negative connotations, finding it misleading and inaccurate.[8][9][10][11] Petrarch's pejorative meaning remains in use,[12][13][14] typically in popular culture which often mischaracterises the Middle Ages as a time of violence and backwardness.[15][16]

https://en.wikipedia.org/wiki/Dark_Ages_(historiography)


Practically everything was lost and had to be reinvented.

Absolutely historically inaccurate - total rubbish. See the above.


Keep in mind that the Europeans didn't learn from the aztecs/mayas. Everything was demolished and forgotten.

They didn't need to. They had "Guns, Germs, and Steel". Watch this short summary of Jared Diamond's Pulitzer Prize winning book. Ask yourself why the Europeans were invading the Aztecs and Mayas rather than the other way round! (Honestly!)

That's an interesting comment. To think that currently there are still tons of back-water 3rd world countries out there. The only thing they have to do is look, learn and copy successful nations and industries. Yet they don't or can't or won't.

Now this is your most interesting comeback. This really does show how important governance is to the lives and personal wealth of the average citizen. I guess even in Somalia and other developing nation situations, while the average citizen is vastly poorer and living a totally different life to us - the warlords still have kit and booty. They still want viable workshops. They still want some people taken out of the total drudgery of generalist subsistence farming, and fed and housed and clothed to allow specialisation. Specialisation is the key. It means certain disciplines are being remembered and not totally lost to the ages. It means that the fragile candle of knowledge can suddenly blaze into a furnace again in the right conditions - should a kinder regime develop over time.

And if those States don't develop back into a trading Federation as I hope? War is also a powerful motivator for discovery and invention. (But probably a vastly worse outcome than local villages co-operating and trading as they sift through the rubble and salvage and relearn everything.)

What makes you think that somebody will dig up a user manual of an iphone and the light of ideas will go on in his head?

Are you kidding me? Talk about a straw-man. (Although - even in the Book of Eli - there were workshops where you could get an old ipod charged!)

No. My blog page talking about basic tractors possibly running on wood-smoke that allow farming, basic Einstein fridges for a local communal kitchen (like an army mess) that allow preserving food and dairy, etc.

Once you're half a year or a year out of the horror (whatever that looks like - nuclear fire, starvation, rampaging mobs, etc) - collapses can be long boring affairs. Subsistence farming is hard and boring. There's no Netflix or internet or phones to browse. What do people do with their time?

Salvage and read. They dig through the ruins, even through old second hand book stalls, looking for entertainment and survival knowledge.

It's not the large town that allows specialization. It's the surplus in energy and food available that allows towns.

That's true but you've missed the point.
Given one town of 5000 people are already being fed, and another town of 5000 people also exists, and you are able to feed them all - you get the GDP for that region of 2 towns as the output of 10,000 people. But the magic comes in if they're all in the same town. The same 10,000 people suddenly produce an extra 30% GDP FOR FREE if you combine them into the one town of 10,000 people. The basic rule? Every time your town doubles, you get 30% GDP for free. I would have thought trying to make things easier after a disaster would be desirable?

I have some doubts about combining two groups of 5000 into one of 10,000 automatically generating more free GDP. Sure there are some efficiencies in reduced travel distance and larger customer bases for each business but are the natural resources (food, water, fuel etc.) available and more easily obtained for the larger city? If you only have just one critical resource like water limited to a population of 5000 doubling to 10,000 just creates a problem not a profit. What if the two are different religions or ethnic ancestry and do not get along with each other?
It sounds like a rule that is full of more exceptions then followers.
As to post collapse tractors using wood gas the problem of collecting the wood without fossil fuel powered tools limits what could be done along with the extent of the surrounding forests and their growth rate.
Battery powered tractors charged by solar panels or windmills seem a more likely option and of course most hydro dams will survive and the power from them that can be delivered by the part of the grid that survives or can be repaired would most likely have food production as it's highest priority if no enemy was poised for evasion.

I completely hear what you are saying. To be honest - it's more a concept I'm just trying to get out there for people to value just how amazing cities are - once you can actually support them. Also, I'm not even sure when this 'Size bonus' kicks in. Does it really only start at around the tens of thousands? I'm not sure - the few articles I read on it didn't talk about lower limits but mainly the upper limits.

Here's a weird factoid: the physicists that discovered this 'law' could measure the average of how fast people walked downtown, and tell you roughly how many universities and hospitals that city had! There are a whole bunch of human behaviours that accumulate into amazing statistics when we get into numbers.

I hear you on wood and electric tractors etc. It all depends what resources are available and what calamity led to the collapse. If you're talking about some war that nuked the cities and burned down the local forests - then you're in a vastly different place to some Steven King like super-virus. (Ever read "The Stand"? He made the point that with salvaging efforts, the survivors might not have to make clothes for many generations.)

My main point isn't even the tractors - it's the skills that lead to basics being rediscovered that lead to a slightly more productive life that leads to more specialisation and skills. A bit like the technology tree in Sid Meier's Civilisation game - and all the accompanying investments in culture and happiness etc that it takes to build a civilisation.

If we're talking a post-nuclear war world, would EV's even work? Electric buses? Or would they be back to this? Wood-smoke bus.

What is possible in a recovery phase after a collapse will of course be determined by the nature and extent of the collapse. A worldwide plague that kills fifty percent of the population being a lot different then a nuclear war with the same number of initial casualties.
But at any level it will take resources and human effort to rebuild anything useful. The amount of resources to rebuild an EV battery factory and assembly line for EV vehicles and tractors might well be less the that required to produce and fuel an equally productive number of wood gas fuel vehicles. I say equally productive as one good EV tractor might out produce ten wood gas burning tractors so be worth devoting ten times the effort and resources to produce it.
This is similar to the artillery shell issue in Ukraine. Dumb artillery shells cost about $1000 each to replace and a single GPS guided Excalibur shell cost $60,000. But the Excalibur shell can fly five miles or more further then the dumb sell and hit a valuable target with one shot and it might take a hundred shots with the dumb rounds to get a valuable hit. Sounds like the math is simple and you should go for the one shot one kill option. But there is a third option that is actually being used. That is using a reusable light drone for as little as $1000 to spot targets and redirect fire so instead of 100 rounds per hit it is taking three to five. So $5500 to kill a tank worth $5,000,000 or an ammo dump containing $250,000 of ammo and starving the remaining tanks of their ability to fight.
But back to rebuilding. As long as libraries and hard drives exist the knowledge needed to assess the best course forward after a collapse will be there for the survivors to use so I expect any rebuilding phase will evolve quickly to where people living in resource rich countries will soon again be living comfortably. Sub Saharan Africa not so much.

An interesting discourse, I will read it from the start but this caught my eye. From my readings of the darkage the medieval settlements actually canalized the works of the Romans for building materials, so in a sense they did pick up the pieces lol. Also their gold coinage still persisted in the West until well after the fall of that half of the empire. I was in a coin shop the other day and there were quite a few examples of Roman gold and silver coins, pre-christ as well. Strange feeling holding a coin that was once used as currency over 2000 years ago.

It's a lack of will that effects nearly everyone touching these empires.

When the Western Roman Empire collapsed it was not an overnight event. It was much more a case of people who were alive at the fall of Rome the city looking around and saying "Things are bad now, but they are sure to get better soon". This became a cultural meme and the following generations continued to look back at the "Glory that was Rome" and expect someone higher up the elite chain to be working on returning to that past glory. This habit of through was after a few hundred years taken up by Charlemagne (aka Charles the Magnificent) who actually succeeded in the broad sense of uniting France, Italy and what came to be called the Holy Roman Empire. Unfortunately upon his death his three surviving sons split the empire he had spent a lifetime building into three slices, east west and central, and from there the divisiveness and crumbling took on a new character so that by the time another three centuries passed the Vikings had come and gone chopping the former western Roman Empire up into hundreds of principalities and tiny kingdoms. Oh and the people who lived through the time of Charlemagne had the same cultural mindset of looking back to past glory instead of forward to what they could themselves do to make a united future.

I think that alone was the drag on innovation and improvement. Also the church was skimming off the profits of all agriculture and what little industry there was in a way that would make a Russian oligarch blush.

It's not that simple. While it's true the Church did some awful things, the church also encouraged literacy and built schools, universities, and hospitals. I think eclipse got it right talking about how there is a lot of cultural baggage around what we call the dark ages. Infact, modern scholars don't even use the term dark ages anymore as they find it misleading. It's still popular among the public though.

Among the more popular myths about the “Dark Ages” is the idea that the medieval Christian church suppressed natural scientists, prohibiting procedures such as autopsies and dissections and basically halting all scientific progress. Historical evidence doesn’t support this idea: Progress may have been slower in Western Europe during the Early Middle Ages, but it was steady, and it laid the foundations for future advances in the later medieval period.

The dominance of the Church during the Early Middle Ages was a major reason later scholars—specifically those of the Protestant Reformation in the 16th century and the Enlightenment in the 17th and 18th centuries—branded the period as “unenlightened” (otherwise known as dark), believing the clergy repressed intellectual progress in favor of religious piety. But early Christian monasteries encouraged literacy and learning, and many medieval monks were both patrons of the arts and artists themselves.

One particularly influential monk of the Early Middle Ages was Benedict of Nursia (480-543), who founded the great monastery of Montecassino. His Benedictine Rule—a kind of written constitution laying out standards for the monastery and congregation and limiting the abbot’s authority according to these standards—spread across Europe, eventually becoming the model for most Western monasteries. Finally, Benedict’s insistence that “Idleness is the enemy of the soul” and his rule that monks should do manual as well as intellectual and spiritual labor anticipated the famous Protestant work ethic by centuries.

The Early Middle Ages were boom times for agriculture
Before the Early Middle Ages, Europe’s agricultural prosperity was largely limited to the south, where sandy, dry and loose soil was well suited to the earliest functioning plough, known as the scratch plough. But the invention of the heavy plough, which could turn over the much more fertile clay soil deep in the earth, would galvanize the agriculture of northern Europe by the 10th century. Another key innovation of the period was the horse collar, which was placed around a horse’s neck and shoulders to distribute weight and protect the animal when pulling a wagon or plough. Horses proved to be much more powerful and effective than oxen, and the horse collar would revolutionize both agriculture and transportation. The use of metal horseshoes had become common practice by 1000 A.D. as well.
6 Reasons the Dark Ages Weren’t So Dark

Although some actions, such as the Medieval Inquisition, are controversial today, the Catholic Church also established universities and hospitals, instigated positive social change and paved the way for economic growth that permanently changed European society.

Education
In 1079, Pope Gregory VII decreed that the Church would build cathedral schools, institutions designed to educate future members of the clergy. Their success led to the development of European universities in the 12th century, whose educational scope quickly broadened beyond religious training into medicine and law. The growth of universities meant that more men required preparatory education in Latin, which was mandatory in university educations at the time. To meet this need, the church also created primary education facilities that prepared men for university study. Through the creation of universities and institutions of primary education, the Catholic Church spread literacy and promoted the growth of intellectual curiosity.

Hospitals
Until universities began to house medical facilities in the 12th century, most medical care in Europe occurred in Catholic monasteries. The church went on to found the university system, which provided facilities and care as well as training for physicians. It was also responsible for creating the European hospital system, which began in the 13th century when Pope Innocent III ordered the establishment of a hospital in Rome. The hospital was so popular that it sparked the construction of hundreds of additional institutions across Europe that followed the same model. These new hospitals meant that medical care became accessible for nearly all European people for the first time.

Care for the Poor
As the Crusades began at the end of the 11th century, commerce began to develop in Europe. In response, European society experienced the emergence of two new classes of people: the middle class and the extremely poor, who were often reduced to begging. Governments during this time attempted to ban poor people from public areas and institute vagrancy laws to keep beggars out of cities. In response, the Catholic Church moved to aggressively protect the poor, insisting they were entitled to basic rights. The Church attempted to protect these by exempting the poor from court fees in ecclesiastic courts and by providing free legal counsel, food, shelter and alms.

Notice they were educating the priesthood not the masses.
I think the records of medical students stealing or digging up bodies so they could do autopsies puts the lie to much of the rest of that.

Originally this was the case. However the schools were expanded to regular students as well:

That was because there was a shortage of bodies for medical research not because it was outlawed by the church:

Most scholars assume that autopsy and dissection were taboo in medieval Europe; if they were conducted, they were illicit and done only on the bodies of criminals by intrepid scientists and doctors, flying in the face of clerical authority in the name of pursuing knowledge.

But Park, the Samuel Zemurray Jr. and Doris Zemurray Stone Radcliffe Professor of the History of Science, discovered quite another story in the Florentine libraries. According to Park, dissection grew out of autopsy, and autopsy grew out of embalming. The interest in specifically women stemmed from a desire to understand the origins of life. As such, it was all sanctioned by the church.

It was always the uterus that was dissected first, according to Park, “except in the case of holy women,” she explained. “Then they would dissect the heart. The thought was, this woman has died, and she might be a saint. We can embalm her because the body is useful for establishing a cult. Then you have her insides, and she said she had Jesus Christ in her heart. Well, you might as well open it up and look for Jesus. The fact is that human dissection is not a Renaissance invention,” Park continued.

“I found that instead of this investment in the integrity of the human body, social history and religious sources tell us that the human body in medieval Christianity was something to be torn about,” she said. “The religion was about dismembered bodies. Christian ritual is organized around body parts. It became clear to me from the religious end that the assumption we had about medieval bodies was not holding up. In the end, I wanted to make it clear there was no religious prohibition against dissection.”
In medieval Christianity, dissection was often practiced

It was much more a case of people who were alive at the fall of Rome the city looking around and saying "Things are bad now, but they are sure to get better soon". This became a cultural meme and the following generations continued to look back at the "Glory that was Rome" and expect someone higher up the elite chain to be working on returning to that past glory.


Precisely, though I would call that lead up to ultimate collapse, the Decline, as in the Decline and Fall, as Gibbons declared it in his seminal work. Others, like Marc Widdowson, have similarly divided the collapse of empires into these two stages. Widdowson's research showed than an empire takes on average 200 years to decline, but the ultimate collapse happens very quickly, in about 10 years. This he defines as a culture transitioning from a functioning government to no government at all, total anarchy essentially.

If we look around we see that 90% or more of the population slavishly rely on government to protect them, feed them, keep order, these people have no concept of life without a structured political system and when I goes, and they are left to their own resources, I imagine many just give up and die, probably of starvation. To me the collapse of the Western Christian Empire, which is a discussion in itself, has been going on for quite some time, 100 years or longer perhaps? Very similar to the decline of Rome, that although it was still functioning and even conquering new territories, was in a moral and economic decline where all the wealth was flowing to the top and the masses were getting poorer. The actual culture itself, the agrarian based "Land of the Free and Home of the Brave" was turning into something very perverse.

No it seems to me that when these final collapses occur there is simply no will to restart the empire and whoever survives goes their own separate way to build a more simplistic life, one full of freedom. Very easy to envisage when you are young I imagine, but for a group of old men and women like the inhabitants of peakoil.com, an impossibility. That's why older people today simply won't countenance the idea that the whole system could fail. It a death warrant to them.

There are no wheelie-walkers in the apocalypse.

Yes, a real achievement. It never fails to amaze me what can be done by a single man once he gets a few devout followers and then the masses behind him. But that was a different land, different people, not Romans, a different empire altogether. It's not uncommon for new empires to take from the achievements of older ones. When people bitch on about religion and how nothing good ever came of it I remind them that our courts and the laws that protect us in the West, trace a path back to Christianity and the law of the old testament.

Fascinating topic Empires.

The “Empire” can also be described as a “dominant culture”.

Right now we have a unique event where “Western Culture” is dominate over the globe.

It is unlikely the decline will be even and at the same rate in all corners of the culture. Some will go quick, some will linger, perhaps even some will survive.

Ibon used to point out that the kids will he fine because they sill he used to the “new normal” and not miss what the never had. There is evidence to that in that we tolerate so much environmental degradation. Our view of “normal” is fixed sometime before puberty. So if we grow up in Kansas that is normal, or Harlem that is normal.

A lot of what we discuss here is our fear of change. And rightfully so, the change will likely be brutal.

My GUESS is that few of us here will have our lives deeply degraded by these changes. Our children and grand and great grads will hear the brunt. But perhaps after that there will he an accommodation and a time of settling into some new normal. Or it may take 500 years. None of us know.

There is a great deal of truth in the "kids will be fine" statement. Look at any of the Colonial experiences where if things were not terrible back in the "Old country" grandma immigrant might be pining away for the country of her youth while her very own grandchildren who grew up in the "new" country of their youth thought it might be a nice place to visit but they didn't want to live there. If you ever get a chance to read some of the interviews with immigrants from the 18th of 19th century who though the weather here in whatever part of the USA they landed was awful compared to their childhood memories and then compare that to what their descendants say about the same weather from their own childhood wherever here is you will see what I mean. If you were young in Greece and old in NYC then the climate in NYC sucked but if you grew up recently in NYC then it was just the way the world was, snowball fights with your friends in the winter and skating on the frozen rink in central park was normal and months of rainy winter weather was awful to you.

In a real sense we don't even need to collapse first do we, we have the numbers, we could realistically build that ideal future starting now, but the will for it is simply not there in the inhabitants of our current civilization. Collectively we don't give a shit. Sure some of us talk and proclaim and invent, but hardly anyone wants to give up their personal luxuries, lifestyles and all this consumption that is leading us to destruction, just for the sake of a brighter future.


It wouldn't be for the sake of a brighter future. It would be for the sake of a darker future, but less dark than if everything just collapsed. And that's why the will isn't there. Most people in a prosperous society can't tell the difference between shades of dark. It all seems too dark for them. Most people in a prosperous society don't know that there is a much starker difference between bad and hellish than there is between good and great. They may even accept it intellectually, but the experience isn't there to back it up.

If he's discussing anything prior to the industrial revolution, then it's irrelevant. We have the scientific and industrial revolution and the 'flattened' economy of globalisation today. Everything is different.

Sometimes it seems to me peak oilers take old historical events - like the fall of the Roman Empire - add a little peak energy theory - and come up with an ultimate theory of collapse. It doesn't work like that. Yes the Roman Empire was in a peak of slave consumption and environmental destruction (their topsoils now being on the bottom of the Mediterranean sea.) But no - we can't generalise like that. We don't need slaves today - we have energy to do that for us. We have the scientific theory and results of all that work. We have 'how to' manuals in old bookstores and libraries and hard drives.

Going off pre-industrial models to say what would happen in a disaster today seems inadequate and irrelevant. We've experienced too much of the modern liberal western way of life - and we like it. We've tasted the lightning (modern electricity) and like that too.

I think it's time for everyone in this discussion to watch Isaac.
Dr James Hansen recommends breeder reactors that convert nuclear 'waste' into 1000 years of clean energy for America, and can charge all our light vehicles and generate "Blue Crude" for heavy vehicles.
