As to Peterson: I read a long article over at Viewpoint magazine that makes a, to me, convincing case that he tends to misrepresents, or hasn't read the works of the schools of philosophy he critizes and a similarly long review of his book in Current Affairs that finds it, using extended quotes, to be full of unprovable gibberish. With those I'm reasonably confident that I haven't missed any big revelations, but I suppose if you have another article to demonstrate I'm wrong, go for it. I specify article since I'd have to scrutinise it cosely.
