I'll take an offtopic digression to talk about authors I love very much, which your comment reminded me of.
That FUAFI notion you just quoted, according to Wikipedia, is a Platonic approach to layered realities, in a very notoriously Christian work of fiction. Nietzsche wrote some very interesting things on the love story between Christianity and Platonism... Most amusingly, in his segment "'Reason' in Philosophy" he arguably comes off as an especially passionate and vitriolic proto-rationalist. It might be an amusing exercise to compare Nietzsche's "Philosophizing with a Hammer" to Hunter S. Thompson brand of "gonzo journalism". The comicbook expy of the latter, Spider Jerusalem, is also very interesting from a LW POV, partly because of the trademark Weridtopia he lives in, partly because of his passionate commitment to spreading the truth about a system he felt was decadent and corrupt, something he shares with both those two historical characters, and perhaps a few more people. With one noticeable difference: unlike them, we like to think we're being objective, and that we've got the science to prove it.
I've just been thinking (a dangerous pastime, I know) and remembering my religious days, and one of the things that made me so anxious back then, and made adopting atheism so gratifying, what the sheer drought of information. I had so many, so many questions, and there were no satisfying answers to be found.
How do souls work? When one dies, what does bodiless existence feel like? What happens in Resurrection Day, do cripples come back as such? Do transsexuals come in the body they identify with? Is it a matter of self-image?
How does God intervene in the gaps? What will Paradise be like? How will society be organized? Will there be further education? Will human nature be radically changed to accomodate eternity? What about Hell? How does it work? What's the point of it?
And what does that verse mean? And what does that other? And what if the letter of the law, once centuries have passed and context has changed, goes against its spirit? What would God actually want me to do? Why am I supposed to guess? Why is it so important that my faith in Him be groundless and unsubstantiated? Why has He stopped giving orders directly, why has he relied on fallibe intermediaries and easily-tampered-with books?
So, abundant questions, very few, very vague answers. Important questions, too, an eternity of one's afterlife depends on them! So, I was wondering: is it possible to come up with a fictional setting, resembling the Theist-Abrahamic vision of the world, but mundane (perhaps a game? a computer simulation? a F(?)AI run society?) in which this drought of information is actually justified?
As an example of what I'm going for, Warhammer 40K's Imperium of Man gives us an example of a textbook fascist society whose every single trait is perfectly justified by the setting's rules. (See the "actually has something consistent to say about utilitarianism" subsection).
In what kind of world would a Supreme Authority's information-management policies resemble God's, and make sense? I'm not saying "be good" or even "be fair", just "make sense". Even in a Kafka-ish, "nonsensical" way.
