The book series "Varieties of Thought" is very bad and completely immersion-breaking, both in terms of writing and content. I think the three following assets should be deprecated (is that how it's called?):

T_Bk_VarietiesOfThoughtTR_V1

T_Bk_VarietiesOfThoughtTR_V2

T_Bk_VarietiesOfThoughtTR_V3

Those three assets are quite commonly used on the mainland, mainly in Old Ebonheart, and in some Dunmeri settlements where they make even less sense (the author calls the Tribunal "three Dunmer magicians, who somehow obtained immortality through profane methods, like the dissident priests claim").

Here are the main issues:

1. There is no named author, and we have no idea what's his/her race / cultural background.

2. The writing is very bad, full of "frenchisms" (lots of incorrect uses of "concern"), and the syntax makes the whole thing a pain to read.

     - ex: "There are sciences which concern themselves with the intelligent beings of Tamriel, like men and mer. These sciences are history, rhetoric, archeology (this could also be described as "practical history"), art, music and lingual sciences (which concern themselves with analysis of literature, grammar, spelling and pronunciation)."

3. The books aren't coherent between one another, and sometimes contadict each other outright.

    - ex: in vol. I, the author vehemently claims that magic and science are inconciliable ("Not only this, magic is illogical and not bound by any laws of nature; it even acts against those laws"), while in vol. II, he admits the possibility of understanding magic through scientific means ("magic is just a certain kind of energy and everything is just as logical and clear as the laws of nature").

4. Lore-breaking.

    - In vol. I: "one colleague of mine, a Dunmer doctor, even found a natural cure for the blight disease!".

    - In vol. I: "the magical purists, like House Telvanni from Morrowind or the mages guild will accuse me of blasphemy, since they consider their magic to be divine". Telvanni accusing people of blasphemy?

    - In vol. II: "The Empire claims that all the different gods are the same."

5. The contents of the books, especially vol. I and II, don't make sense in the Tamrielic cultural context.

- vol. I is written by a hardcore rationalist and technophile that treats both religion and magic as useless superstition, that should be replaced by Science and Technology in order to lead Tamriel towards Enlightenment. Ex: "I talked to a lot of people I consider to be intelligent and wise, but most of them gave me the following answer: "Why do we need technology, when we have magic?"" => The author incorrectly draws an equivalence between science and technology, and even more incorrectly draws a hard distinction between science and magic, when Tamrielic scholars often have a scientific approach of magical matters.

- vol. II looks like it’s been written by someone who just had its first class about René Descartes and Blaise Pascal, and didn’t pay much attention. Ex: "The first question is: How can we trust our own senses? Do they not trick us? How do we actually know that anything exists out there? Or do we live in a dream?"

- vol III is Classical Greek philosophy soup with Altmeri names sprinkled on it. Not uninteresting, but the references are a bit too transparent for a fantasy universe: Erundil, Volanaro and Imare are obvious substitutes for Socrates, Plato and Aristotle.
