> Reading “thinking fast thinking slow” should not take 8-9 hours... it could easily take 50 (after all, it represents many years and thousands of hours of work by the preeminent thinker on the subject).

but would it really? a good way to know is by letting the author teach you the book. do you think it will take 50 hours? think of university courses in which the teacher is teaching their own book. they will not go through every line and details although they must have found the details important enough to be put in the book; yet you will learn key ideas that will help you grasp the subject.Even if you learn the details in depth ,when they are not useful for you, you will eventually forget them.

As for divine comedy, It is a work of art that can be interpreted in many ways , it inspires many people in different ways that even the author would not have imagined.

so if you spend 50 hours reading a non-fiction do you enjoy all of those hours? do you remember all the details you went through? if you are only going to remember some of the key ideas then why bother spending 50 hours on it?
