I think there's something else going on here, other than the humility of researchers who claim to be unable to understand Mexica culture. Failure to imagine what it's like to be someone else, from a different place, a different time, with different ways of thinking -- is perhaps the biggest reason why we have so much violence and hatred in this world, and modern scholars are just as guilty of it as warmongers and pro…
Let's look at some of the aspect of life described in the article. Assume I'm just some artisan, good at my job, respected for my ability to work materials into goods. Making the odd innovation here and there. As a result I'm not in the ruling elite, nor the warrior "caste", but I'm doing pretty good for myself compared to most people.
Basically let's just say I'm equivalent to a decent software developer in our society.
I can imagine all sorts of things:
* I'm ashamed that I'm not a member of the fighting classes
* I don't have strong opinions of that fact
* I have a strange (to me in the 21st century USA) relationship with those of the fighting classes
* similar thoughts toward ruling elites, plus:
- Do i worship them or revile them? Do I have differing opinions on different people in that class, or do I view them as an undifferentiated mass?
- Do I expect to have any influence, or none, etc? How do I feel either way? (I can imagine having influence on the noble class but being rather upset because they are supposed to have a direct line to the gods, and why are they asking me?)
Other things I can imagine:
* Do I fear being sacrificed? Am I ashamed if I am afraid of it?
* Do I see the sacrifices as great? Or do I see them as an unfortunately necessary unpleasantry? Or do I see them as a source of shame because the rulers are out of touch? Is there an apocryphal tradition of the Gods actually being gentle and not wanting blood sacrifice, but this is being ignored by the priests?
* If my kid gets recruited to the military, am I proud or scared or both? Do I prefer his capture or his death in battle? What conduct makes me proud or not?
Basically my point here is that imagination and lack of data combined results in a truly honest answer of "I don't know which of the options for any of the questions above is right". This leads to a simple "I don't know", not because I can't fathom it for lack of empathy or imagination, but because I can see many many different ways it could be experienced.
