I agree that Peterson's philosophy might boil down to the individualist's insistence on self-reliance. But if anyone's overthinking that platitude, it's surely Peterson and his many tangents, no?
I wouldn't have a problem with the use of religious myths to illustrate philosophical points, but the author would have to be up-front about it. Instead, Peterson obfuscates his religious status, and I think that's largely a business decision: he doesn't want to alienate his base. But it's also because he'd rather not admit that his worldview is incoherent, as I argue in this article.
I don't say, though, that Peterson's lectures are worthless. Indeed, I was less harsh in my first critique of his worldview (link below).
I'd agree that he's a prominent critic of postmodernity, but not so much that he's the most astute one. Frankly, I think my assessment of postmodernism is closer to the mark (I could cite numerous articles). Peterson wants to tie postmodernity to Marxian totalitarianism, and so on, but that's a cheap shot and it doesn't get at what's fundamental here. John Vervaeke is closer to the truth when he speaks of a "meaning crisis."
I think postmodern pampering is part of consumerism: we're becoming like those dainty adult babies in the movie WALL-E. We're spoiled by our First World problems, and we're slaves to our technology., whereas the reverse was supposed to be the case. Western culture is also being feminized and infantilized.
