I'm not disagreeing with you at all, but I have personally found most philosophy "classics" painfully hard to get into. That doesn't mean they shouldn't be respected, but the truth is that sections of society (like myself) do rely on the people specializing in philosophy parsing it into current language and metaphor.
Truth is hard to get into. If it were simple and digestible, we wouldn't all keep seeking it, ever hungry for it... It has to be grappled with. You can't shake truth's hand and have a seat and have it flow into you smoothly from the latest self help book.
Look I mean, many famous artists don't understand their work at all. You don't have to have read philosophy to create something meaningful or make an insightful comment. But if you are going to start using terms like Judgement or Taste, you really ought to know where they come from.
