I agree with you, maybe books are not the ideal format for acquiring knowledge.

I read a lot of fiction books, mainly classics for pleasure. And what I found unique is that only in books I have access to the interior monologue of the characters, their thoughts, and on some occasions, direct access to their "stream of consciousness".

I love it, and I discovered that some characters (but in reality it's the authors) have a similar process of thought, and some others do not, and notice and sense things differently ...
