If it's a textbook, perhaps not. A great author is one that will turn the sum of those ideas into something completely new. Something that will make you think more than any individual drop of information in the bucket of the book's wisdom.

That's why I like analytical essays more than books when it comes to nonfiction 😅 It's a shorter read, but a good author will still come around to that greater point that you were supposed to get from a whole book
