When we read authors too close to home that say things we already think are true and share our views, we'll let almost any nonsense argument slip by. That's a waste of time if I ever saw one.
Reading philosophy books is difficult (for me), because my instinct is to have a conversation, ask questions, explore notions and branches, spend more time on some things than others. It's the railroad aspect of philosophy books (whether I "agree" or "disagree", which is rarely binary), that makes them feel stifling :-/
Even the classics like Plato - or perhaps most particularly classics like Plato - they tend to lose me after the first dozen "As everybody can plainly see...." "We can all agree that..." "It is an understood fact that...".
Maybe it's you who has already made up their mind?
