Because "faithless" has no meaning until you have a modern concept of "faith," which ancient polytheisms really didn't, because it's an invention of monotheism, which is part of why the Wall is CRAZY out of place in FR. There's no such historical thing as a "devout follower of Ra;" devoutness is an anachronistic concept when applied to ancient Egypt.
The idea being represented in the FR is more one of sinning or doing something the gods don't allow. That is quite a common idea even in polytheism.
This disappears down the scholarly rabbit-hole real fast, and I ain't a paid and properly trained educator, so it'll be up to you to build on this (try
her books as a starting point, especially
A History of God and its chapters on how Judaism's concept of monotheism likely arises out of a more ancient polytheism including how Abraham and Ezekiel refined that concept; also interesting for different reasons: Alice K Turner's
History of Hell). For our purposes here you might use this as a starting point: like in FR, a god or an afterlife in most ancient polytheism wasn't something you
believed in, it's just something that
exists.
I'm aware of this. That's why I admit faithlessness maybe isn't the best word. Offending the gods was a very real idea in polytheism and it certainly didn't have a great deal to do with what modern people might consider good and evil.
Like a king or a spice vendor or a temple or a rock or a squirrel or a lamp.
And if the lamps says, "You will choose one of us to worship or you will end up on this wall." The person doesn't argue with the lamp. He does it. Let's say you appeared in the FR and started arguing this concept, the common man would think you were nuts and tell you, "You better pick a god to live with buddy or you're going to end up screwed."
It doesn't make sense to love Ra any more than it makes sense to
love lamp. The priests of Ancient Egypt didn't sacrifice animals because they were showing their innermost conviction, they sacrificed animals like you pay taxes or like you give gifts - because you have to, or because you want to cement a social bond. You kill a cow not because of your inner beliefs, but because of what you think it will function as - a way to make the sun hear you when you ask it to allow rain to fall.
So someone not sacrificing a cow isn't about their ortho
doxy, it's about their otho
praxy. What they
do, not what they
have faith in.
They all have faith in the gods in polytheism. It wasn't even a question. They sacrificed because the gods told them to without asking the question, "Is this good?". It was good because the gods said it was good. You are applying a modern idea of being allowed to not choose a god as in not follow the rules which the FR deities consider faithless. It is no different than failing to sacrifice and ending up in the mouth of a monster having your soul destroyed because you didn't pass the test of the feather.
The lamp doesn't care what you believe in, it cares what you do - your ritual of plugging it in and flipping a switch makes light. Don't do that ritual, and there won't be light. Do that ritual, and call that lamp ugly and stupid-looking and say that the world would be much better off without it, and still, there is light.
How is this different in the FR? Don't choose a deity, end up on the wall. How is that concept different? Your soul is still judged. You can still be judged false for not following your deities rules. This is the agreement and lesson of the gods. If you lived in ancient Egypt and the gods said choose one of us to follow or this happens, they would do it, not argue whether it was good or evil. To use your analogy, the lamp said this is how it works and you do it or the lamp is angry.
In the Real World, it was possible to not sacrifice to Ra and still have a good rain. Those who had a Ra-model of the cosmos didn't think this was a contradiction, they just imagined Ra must be pretty generous and that, of course, since back home they had priests of Ra making sacrifices, that Ra of course preferred their hometown to this place. That's why their society was probably beter than this barbaric hinterland! Presumably in FR, it's also possible to not sacrifice to Chauntea and have a good harvest - she's Good, she provides for folks, and of course she likes those who sacrifice to her better. Presumably, dragonborn farmers still can grow food.
The afterlife followed this model. It wasn't something you believed in, it was just something that simply was.
And this is the afterlife model of the FR. The penalty for not choosing a patron deity is you go to the wall of the faithless. How is that different than doing something that makes you fail the feather test or offends the gods and getting cast into an unpleasant afterlife? You've read Greek myth. You could be the nicest person in the world and say one thing that offends Aphrodite, boom, you're a gorgon. You could live a great life in the Viking world helping people, but die by drowning and end up in Hel's afterlife.
What the gods manage in the real world is irrelevant to their afterlife requirements. You still sacrifice to the appropriate god to get something like good crops. Good crops might happen anyway. But if you want to have an afterlife not on a wall, you pick a patron.
This fits fine with the FR because they are not a united pantheon like the Egyptians or Greeks. They area very divided pantheon, even the gods of good, that require individual worship. Why does this idea of a punishment for not choosing a patron deity in a pantheon system like FR cause you such a problem? I cannot think of a single reason other than it does not suit your idea of goodness. Then again I doubt the Greek or Egyptian idea of goodness would have suited you either. It wouldn't have mattered to them because if the Egyptian or Greek gods decided it was so, you would have no say in the matter.
So, of course, it couldn't judge you based on what you prayed to or believed in - there were atheist philosophers and foreigners who said it was really Helios up there and all those people still died. That's why the feather of Ma'at weighed order and chaos, not faith. You were a merchant who lived in Memphis and sacrificed to Helios? You were a farmer who never really bothered with the gods? You were a priest who thought Ra was a massive jerk for that drought a few years ago? You were one of those atheist philosophers, or maybe a remnant of a monotheistic sect? You were that hinterland barbarian? Doesn't matter. Did you support the social order? You're in. It doesn't matter if you know the truth of the world or not, as long as you are a "good person" (you support the social order), you're fine. Or at least as fine as anyone else (a lot of ancient polytheism had the afterlife as uniformly unpleasant unless you were some sort of special mythic character - or a warrior bound for Valhalla in the case of the Norse)
Yes. Uniformly unpleasant regardless of how "good" you were. Why is the FR Wall of the Faithless not similar? Why is the requirement to choose a patron deity in a pantheon system like FR not a good way to mirror how their system works? They are not a unified pantheon. Polytheism had punishments where good and evil were decided by the gods. So you want the FR to somehow come up with a single idea of good and then have the gods adhere to it in essence changing the pact they have right now. You basically want them to change the rules.
Don't sell me on this idea that the Wall of the Faithless is any different than the feather test which could well include not paying proper respect to the gods (as a whole) as part of this test and ending up eaten by a monster for failure.
D&D in general follows this model pretty well - souls go to the plane matching your alignment if you didn't worship a deity. You're judged on order and chaos and on selfishness and altruism (by no particular entity, but by the multiverse itself) and you shuffle off to a place filled with souls who entirely agree with you about those things.
This is not how the FR works. You go The Fugue Plane regardless of alignment. There are you judged by Kelemvor. Only once you have been judged are you sent somewhere else. You can petition your deity to take you in.
But then there's this Wall...
You are too caught up in what the word "faithlessness" means rather than the entire concept of what the wall is for. It is the rules of the afterlife in the FR. No different than the idea of the Egyptian feather. The rules are clear. You know what you must do.
You keep bringing up that polytheism doesn't have faithlessness, which is true only to the degree that people wouldn't even contemplate this idea. They definitely have punishments for breaking the rules often referred to as sin or evil. Just as they have an idea of goodness or purity. It isn't solely a modern idea. If you break the rules even if you wouldn't judge them as good, then you might end up in a bad place. For example, let's say you failed to serve your master correctly in ancient Egypt. Your soul is weighed and you are judged a disobedient slave even though you have been extraordinarily good feeding other hungry slaves and doing right by your family, thus you are cast into the mouth of a monster to be eaten. Would you be offended by that and start say rebelling against the Egyptian gods so that you would end up eaten as well? Or would you be a more obedient slave?
The Wall of the Faithless is the same concept. It is considered wrong behavior to not pick a patron deity. You receive a punishment for it. Why? Because the pantheon isn't unified. This is the system they use to manage the afterlife because they don't generally have planes of a particular alignment that are protected without a deity. If you go hang on a Neutral Good plane in the FR afterlife without the protection of a god and his servants, then a group of demons can come grab you up.
Even in some forms of polytheism the afterworld was filled with monstrous creatures that if you didn't have the protection of the gods, they would eat you. Or other unpleasant things would happen if the gods didn't manage the dead.
How is this different conceptually as far as the general idea of it in the FR? There is a punishment for failing to pick a patron deity due to the structure of the plane. How is this different than say considering it an evil act not to properly serve your master as a slave? Or considering it evil to not have paid proper sacrifices to the gods? These were definitely sins in ancient polytheism that could get you sent to the wrong area if you failed to follow them. They were in essence considered sinful or evil acts.
It is not enough to just be good, you must be good or righteous in the way the gods require (or the one god in the Egyptian myth from whom the feather comes) to have a pleasant afterlife.
