Humans lived in a world with years long winters, objectively real magic, under the oppression of a thousand year dynasty of kings who enforced their rule through dragons?
I think I missed something in history class...
And all of these issues are something we can find a solution to looking at real history. You do know that there is entire discipline of alternative history?
Therefore, none of these things justify doing just whatever.
And if you do not understand or care how fantastical elements would impact the society... simple: do not use said elements.
And it was Martin who claimed that he was going for realism when writing the series. Maybe,
just maybe, you should not claim that your aim is realism if you are going to throw any and all realism out of the window soon afterwards?
"the only thing" is that they share absolutely nothing with the history or traditions of Earth. Yeah sure it's an alternate Earth, but it's impossible to project real-life Earth onto it because they don't have the same history.
Yet they share
absolutely everything.
Westeros is supposed to be a feudal society, is ruled by a king, it has feudal relations, even feudal titles. And that already places some hard limits on what you can and cannot do with it if you want it to be internally consistent or even just sane.
As I said: it is fine to depart from real-world history.
But such departure has to have reasons, and by that I mean, reasons in worldbuilding - not just "I got my ass comatose from alcohol and it seemed such a good idea".
It's not really all that radical. Radical would be Westeros being a Medieval Communist Republic or something.
Planetos by and large is VERY similar to Earth... with a few details that are not exactly the same due to a different cultural history.
And many more details that make absolutely no sense at all regardless of what "cultural history" you assume.
In some cases, 2 + 2 simply
is 4. And then comes Martin and writes down 5, and gets praised for his mathematical skills.
Religion has had varying degrees of importance in different societies across Earth at varying points in time.
I don't believe we have all the answers, but it shouldn't be an absolutely outlandish idea that a society that shares literally no history with Earth will have different traditions than Earth.
By and large though, the general answer is centuries of Targaryen rule. They were more interested in ruling themselves than allowing a church to have too much influence. It's not that outlandish... make a small butterfly to real history and imagine a medieval Europe where the Kings don't pay attention to The Pope.
There is just absolutely no reason why a vaguely Medieval fantasy society absolutely HAS to follow a strict religion.
I wasn't talking about strict religion in the sense of Catholic Church-like influence on political actors.
Influence of religion goes way, way deeper than that. Fact is that humans simply cannot escape religion. Even today, you simply do
not have irreligious people. You have people who have supplanted Christianity or Islam with Progressivism, Communism or whatever... but religion is there.
And medieval religions were
traditional. Things such as nihilism, Marxism and such are a product of societal and moral breakdown that began with the era of absolutism - well
after the Middle Ages. Medieval people believed in God - and by that, I mean actually believed.
Yet in Westeros and Planetos by and large, attitudes are distinctly postmodern. They shouldn't be - Westeros has, at no time in history, gone through processes that should have produced such an attitude. Even if old religions lost sway, response should be the spread of new religions. And to be fair, we
do see that particular process. But again, at no point do we see religion having anywhere as much influence on culture, thought and behavior of people in Westeros that it historically did.
Targaryens may have broken the Church, but there is a
massive difference between breaking the Church and breaking the moral influence of religion. Hell, "breaking the Chuch" would, in a medieval society, merely mean making the Church subservient to the temporal authority of a king. Because that was all you
could do to begin with - completely removing influence of the Church was simply impossible.
It was only the Protestant Reformation that actually began the process of breaking the moral influence of the Church.
So yes, even with those factors you have noted, Westeros should have been
far more religious than it is presented as.
In the real world, building upon all of the historical events that led them to that outcome.
Planetos does not have that same tradition nor does it share any of those historical events. The events there led religious orders to being... a thing that exists, with varying degrees of power over time.
The Order of Maesters was rich as a consequence of it's academic function. They were also influential as a consequence of their academic function, plus being largely untouchable. This allowed them to maintain things such as the Citadel, education and so on...
And how and why would their academic function allow them to be rich and influential?
That sounds like Fallout Online... Duke Plasma Gun was rich as a consequence of shoveling brahmin shit... Duke Plasma Gun was influential as a consequence of shoveling brahmin shit...
sure, but how and why?
In reality, it doesn't matter if it is the ancient Egypt, Rome, Greece, medieval Byzantium or Europe, or China... religion always gave power and influence that was unmatched outside perhaps royalty itself. And most of the time, kings
were priests, precisely because of the influence of religion.
You won't really find any society where kings were philosophers. Sure, there were "philosopher kings", but even then their authority was largely based on religious justifications, not philosophical ones.
In short: academic institution could only exist as a consequence of its establishment by a) the state or b) the Church. If Citadel and its Maesters were established by Targaryens to help unify Westeros, or else by the Church of the Seven to do the same, then I wouldn't have much issue with it. But in either case, they wouldn't be anywhere as influential as in the story.
The Order of Maesters appears to generally function as a medieval religious order would, just without the religion part. I don't know why that is such a difficult concept. They don't need administration. They function in essentially the same fashion as religious orders did, and they even at least pay lip service to the religion of the land. They're just WAY more interested in the learning aspect than the religious aspect.
Why is a world that isn't dominated by religion so unbelievable?
Because "world that isn't dominated by religion" makes no sense. World has
always been dominated by religion, even today it is dominated by religion - it is just that many religions today are secular.
As I said: Order of Maesters can be either an institution of the Church or of the Crown. And latter would require something akin to the 15th century pseudo-absolutist monarchies or else the Byzantine Empire, both of which were very far removed from the Dung Ages feudalism that Martin seems to be trying to portray.
There was a very specific set of circumstances that played out to make that happen...
...a very specific set of circumstances that did not happen in Westeros.
Except it wasn't all that specific.
In ancient Egypt, many priests were also physicians. And of course, prests were astronomers.
In ancient Rome, again, priests did a lot of science in addition to regular duties.
There
were scientists outside priesthood, of course. But here is the thing: they were either sponsored and organized by the state, or they were independent and relied on donations by mecenas, employment as educators by rich people, and so on.
There was, to my knowledge,
NEVER in history an international
order whose purpose was learning that was independent of a religious organization.
Frankly, I think that is just a consequence of Martin subconsciously hating the Catholic Church and wanting to avoid giving it recognition for the role it historically had in scientific development.
Again I just don't see why the concept of a generally feudal medieval society without a particularly strong religious influence is just so outlandish.
Concept of a
premodern society without a particularly strong religious influence is utterly outlandish.
That influence doesn't need to be obvious, but it needs to be
there.
The Targaryen's were supposed to have purple eyes...
Obviously, GRRM is a complete and total hack because i'm looking at people right now and I don't see anyone with purple eyes. What an idiot.
And DRAGONS?! Um, hello George, you hack. Show me any historical record of dragons. You can't? What an idiot, trying to tell me DRAGONS are a thing. OBVIOUSLY, he's completely out of touch with the world.
Please don't be a dumbass.
That is fantasy. Fantasy elements are fine.
But that doesn't mean that massacring HISTORICAL elements is automatically fine.
Especially when Martin himself has claimed that he has writing realistic fantasy as goal.
