For anyone struggling to figure out where to start learning, here are some of the most important documents I've come across. As always, exercise discernment, as there is no guarantee that any of these are what they present themselves to be, or that they've remained unaltered over time.
The Bible - Should go without saying. Probably the most dense collection of wisdom ever collected in a book in the west, by a lot. There really does seem to be something unique about this book, as it often seems to present pertinent information any time you look to it.
Sinuhe by Sinuhe - An ancient Egyptian novel describing a very similar crisis to what's happening today.
The Apology by Plato - A record of Socrates' trial, where he explicitly states the nature of this world's darkness.
On the Origin of Language by Rousseau - Explores the development of language from the very beginning, tied in to the overall development of human society (from which it is inseparable.
Poetic Edda by Anonymous - The closest thing to a Hyperborean holy book which exists. It's quite notable to me as the king of the Gods, Odin, is primarily characterized as a relentless seeker of wisdom, and as such it is quite blunt and straight forward about many aspects of the world which are shrouded in uncertainty and mystery today.
Hamlet's Mill by Santillana - An attempt to trace the transmission of knowledge through human history, by focusing on the myth of the one and future king. Personally I think his premise is entirely wrong, and that the myth appears everywhere because it happens everywhere, and isn't just a story, but it's a superb primer on how this story has played out in many desperate cultures.
The Histories by Herodotus - The world's first dedicated "historian" recorded as much as he could about the notable occurrences of his times, believing that it was important for humanity to remember what people had done and why they did it.
There are obviously a LOT more important works out there to explore, but I wanted to give a brief "starter" for anyone interested, but overwhelmed.
