The mythology of our world? it isn't quite the Aedra and Daedra, also only one of few religions that describe their god / gods as un-sentient.
and don't you mean it's not an uncommon description for gods and powerful spirits? We don't really interact with Gods in our world to factually state that they are commonly un-sentient.
While some of these seem necessary, how does this do anything but describe them as sentient? Most of everything a Daedric prince does and says all falls back on how they feel, or perceive things, they seem to have a common opinion on which to judge others by.
Malacath, he has compassion for the unfortunate, the spurned right? How can he feel compassionate if he can't feel? Not to mention Malacath wasn't even always a daedric prince, Trinimac the Aldmer Hero doesn't seem to lose sentience as Boethia craps him out.
Azura cares for her followers,
Sheogorath has an opinion on his favorite septims (Pelagius and Martin).
That said, it brings up another interesting concept.
If the Daedra and Aedra are un-sentient, how does a mortal mantle them? Get rid of your sentience of course!
But with monkeymoness's logic, a mortal could also mantle a volcano, or any inanimate object.
Or, there's a bit of a connection between these mortals and Daedra / Aedra. perhaps they're both sentient, in that they walk a specific way, and a mortal can walk like them until they walk the mortal.
I just don't see "Walk like a volcano until the volcano walks like you" adding up well.
