The Last Refuge

Yes, I found this delightful, for two reasons. First -- well, do you recall Gandhi's famous quote? "First they ignore you, then they laugh at you, then they fight you, then you win." For many years now the radical Left has treated the ongoing decline of industrial civilization as a temporary irrelevance, just another set of proofs that late capitalism was about to fall over dead to be replaced by some imaginary socialist paradise or other. More recently, a certain amount of shrill mockery has come from the radical Left when the reality of decline gets pointed out -- the phrase "declinism" got a certain amount of use in that context. Now, though, they're fighting; the next stage will follow in due time.
You might be surprised, dear reader, that an article in a publication such as CounterPunch would insist on sudden collapse rather than, say, rallying yet again around the shopworn fantasy of proletarian revolution or what have you. You might be surprised, for that matter, that Collins proceeded to trot out the same talking points that apocalyptic fantasists have been using to insist on the imminence of sudden collapse since long before I started writing about the ongoing decline we're in. (Those of my readers who've been around since the days of The Archdruid Report already know all of Collins' four arguments well enough to repeat them in your sleep.) Still, that's to be expected at this point in the historical cycle.
The reason why Collins and so many other people insist that we have to collapse -- we can't possibly decline like every other civilization in human history -- is that the ongoing reality of decline challenges the core act of faith at the heart of the modern mythology of progress: the belief that our civilization is unique and thus can ignore the lessons of history. (All four of Collins' arguments predictably boil down to exactly this: "But we're special!") A sudden cataclysmic collapse leaves the fantasy of progress intact; in a sick way, it can even feed into that fantasy -- "Look at us, we've progressed so far and so fast that we can even destroy ourselves!" The process of decline that's going on all around us right now, by contrast, drives a stake through the heart of the fantasy and shows that despite our toys, we're following a historical arc that was old when bronze was the latest thing in high tech.
There's another factor at work here, though. Follow the trajectory of apocalyptic fantasies through the history of ideas and you'll find that down through the centuries, in the Western world, belief in apocalypse is an admission of defeat. Social movements that are on the upside of their arc convince themselves that the world will improve, especially once they take control of as much of it as they can; it's when those hopes are blighted and the arc slopes downward that daydreams of imminent doom exert a potent emotional attraction. It's not quite true to say that it's all over for the American radical Left but the shouting, but it's heading in that direction -- and those of my readers who've watched the way that so many supposed liberals have rallied around the senile gerontocracy in DC in recent years, ditching their ideals right and left in order to concentrate on hating a populist movement that's actually improving the condition of working class Americans...well, let's just say that this latest bit is definitely writing on the wall.

Date: 2020-03-21 06:53 pm (UTC)When I was a teen, vacationing in Bermuda, I overheard a discussion about why the hospital on the US airbase there had been abandoned. Seems the contractor had used seawater instead of fresh to make the concrete. Perhaps 1947?
Memory does not hint at whether the cement or the rebar failed first, but I do recall that the buildings that could be seen from the public road looked fine.
Concrete
Date: 2020-03-19 02:33 pm (UTC)So, from I've read it's mostly down to costs - modern (portland) cement is cheaper to make, it dries hotter and sets much much faster, and you need to use far less actual cement. Roman cement can take up to six months to set (or rather, to gain a significant percentage of its ultimate strength), whereas portland cement sets in hours and dries in weeks. Roman concrete contained up to 65% cement (and about 35% light stone), whereas modern constructions have the reverse numbers; 11% Portland Cement and 67% aggregate and 22% air and water. So less cement used also equates to cheaper building costs.
The Romans did not use reinforced concrete - most modern constructions are dependant on the strength of a lattice-work of metal rods worked into the concrete. This allows for skyscrapers and the like - modern constructions.
What tends to utterly destroy modern structures is concrete-rot, when the metal bars within the reinforced concrete become exposed to the elements, then start to rust and expand, pushing the concrete apart and cracking it through. Once this process starts it is self-reinforcing as more and more water can get to the metal through the cracks.
Modern concrete structures have a lifespan between 30 to 100 years. They are made with this in mind. They are cost-optimized for construction, not longevity. Any kind of concrete hardens out further when given time - many surviving Roman constructs have had thousands of years - but especially Roman concrete exposed to seawater, as it creates tobermorite crystals within the concrete that prevent cracking and tearing.
Investors would rather have a building up in a few weeks/months made as cheaply as possible, that can then house profitable businesses or homes for a few decades before crumbling down.
(Actually it's quite like why modern statues are poured concrete rather than sculpted from natural stone - the old method is in many ways superior, but it has become unaffordable. On that note, many "brick" streets are also poured concrete nowadays, with a press with a brick-shaped imprint being run over it to imitate brick. Actual brick roads are mostly found within the old city centers here, and these bricks are carefully taken out, the road evened, and the bricks relayed. It has also become customary to add a single layer of bricks on the outside of a concrete building to imitate the, older, quality brick constructions... anyway, moving on.)
Now I'd argue this attitude is not helping our current global predicament, but I think it is an inescapable effect of capitalism. It's a short-term-thinking system (usually only up until the next financial quarter). It's much like how we no longer print encyclopedias anymore, but have all the information online - when our civilization winds down, most of our buildings will disappear utterly within a century, like a dream suddenly ending and falling apart. Quite poetic, really.
Finally, though we know the ingredients of Roman concrete through lab-analysis, we don't actually know the recipe, i.e. we'd need to experiment quite a lot before we'd be certain we truly recreated it. I'd personally love too see beautiful structures erected that will still stand millenia from now!

I was astounded when I was doing some research on ancient discoveries to find that the ancient Chinese were building automata, early ancestors of the robot, more than 3000 years ago and that the Hellenistic Greeks, the Carthaginians and the Romans were building huge ships nearly as large as the fabled Treasure Ships of Admiral Cheng Ho more than 2000 years ago.
It's really quite sobering when you think about it and certainly puts paid to the idea that the Faustian Culture is something oh-so-special.
