Possibly a critique of deriving truth from intuition, which leaves no way to critically distinguish between two conflicting ideas, much as you can't distinguish between cows by color at night.

Hegel wasn't exactly from the Strunk & White branch of philosophical writing though, so I could easily be wrong. :)

dang, you say we should avoid those two topics, but don't say what you think it would be productive to discuss instead, much less give any examples yourself.

I could be wrong, but perhaps this is because you would rather that modern China simply not be discussed at all.
