Ah yes, I do remember, now you mention it, reading somewhere about that all-meat diet of his. Also he abuses, or used to abuse, some particular drugs as well. (Was it here I came across it? Maybe this very thread, read earlier and now forgotten? Whatever.)
In any case, that's an interesting observation you make: that conmen end up fooling themselves with their BS. Not that I've thought closely about this, but I guess I would, like I said in a previous post of mine in this thread, regard --- would have regarded --- those two categories as separate: the BS'ers and conmen and charlatans, on one hand, the ones that knowingly, deliberately mislead their marks; and on the other hand, those that mislead others because they themselves are victims of bullshyttery, like priests and preachers that believe in their BS. Of course, as far as their actual message, and as far as the (baleful) effect they have on the world, that's a distinction without a difference: but still, there is indeed that distinction, is what I think/thought. You're saying it's more like intersecting Venn circles, or maybe even one circle the subset of the other. ...Interesting! And you may be right, you know. About charlatans believing their own BS most times. (Not always, though. Definitely not always. Certainly there are some that know their shtick is BS, and still they flog it. So maybe the intersecting circles thing.)
