One of the main things that almost every single person who's debated on this website has probably been asked, is to provided sources for their arguments/opinions. Most of the time, they provide witness events in the game, dialogue from NPCs or major beings, or books. But I've wondered for a long time, how when debating deep concepts in the TES Universe, how books written by mortals prove anything, and how accurate these are.
What I'm saying is, let's say you're in a debate over the powers of Aedra and Daedra, and you use the book Aedra and Daedra to "prove" that the Aedra can "die", and therefor less powerful than their cousins, the Daedra. Do you think the author of the book would really know of if Aedra can die, a mere mortal who's likely never even met any of the Aedra or Daedra, let alone saw or measured their power. When you think about this, almost every single book regarding the deeper lore of the TES Universe can be considered just speculation, since unless these authors witnessed or examined these complex pieces of lore or theories, why would they somehow know it? Makes no sense, does it? Just some food for the thought.
Do you agree that books are speculative for deep TES Lore for the reasons I explained (different ones even), or do you think they are, and/or that I'm wrong. Express yourself in the comment section!
