But generations of philosophers who have described the next couple of thousand years as "footnotes to Plato", and treat philosophy as if it can only be understood in terms of one very dead guy... It turned me off philosophy for a very long time. Maybe they aren't stupid, but they at least lack the tool kit for showing me the merit of their position.
I had a longer written reply but it turned out pretty snarky. In my opinion Philosophy is built upon just like Mathematics otherwise most people can't meaningfully engage.
That isn't to say that every author and philosopher is infallible and you must assume they are smarter than you at all times, but just that you need to acknowledge that very famous works are typically very famous because, in the opinion of very learned people, they contain depths to be plumbed. If one isn't seeing those depths, he needs to look harder.
