I do also have books which disagree like Sam Harris for eg. who thinks Chomsky is a joke. I definitely agree that reading a diverse range of authors is important but it’s not as simple as that. If a book chimes with what you have already perceived/thought (which may well be correct if you are an INFJ lol) then that adds weight. The suggestion that reading one book is not enough is too simplistic, a bit like my ISTJ brother who doesn’t believe anything I say because he accuses me of confirmation bias. If that explained every opinion, humanity would still be living in caves etc. . If truth isn’t knowable, we would all be fucked.
