i don’t pause or rewind. i just tune back in later. i know the book well enough it’s not a problem. i know what’s going on where i pick up.
i do the same thing, sometimes, with books i’ve never read before. if that’s how it’s convenient to read, so what? why try to get every detail out of the book? if it’s so great, read it again later in the same low-burden way.
figuring out what’s going on after missing some is interesting anyway. both with books about ideas and books with plots.
and it’s actually not fundamentally different than reading without skipping anything – where you also have to make guesses and use creativity to figure out what’s going on. all novels give incomplete information about the plot and leave you to try to figure some things out. all philosophy books try to explain a lot but can never do all your thinking for you.
