Ramblings about the role of knowledge in doctrinal religions

So I was talking to Bunny the housemate the other day about some of the CSR (cognitive science of religion) stuff I've been reading lately. Bunny is originally from Hong Kong, and we were talking about Robert F. Campany's essay 'Xunzi and Durkheim as Theorists of Ritual Practice'. Campany describes the views on ritual held by the Chinese philosopher Xunzi (a Confucianist or group of Confucianists from sometime around the 3rd century BCE). Xunzi apparently believed that ritual was a very important part of every day life, but disagreed with the opinion (mainstream within his own society) that it was important primarily because it appeased gods, spirits, ancestors and other supernatural beings. Xunzi argued that although his society's rituals contained numerous appeals to supernatural beings, their main purpose was not to appease these beings but to help cultivate and civilise the human participants, by providing a "model" for behaviour (see p.207, 211).

Anyway, we were talking about this, and Bunny mentioned something I thought was interesting: as far as she knows, the concept of "forbidden knowledge" doesn't really exist within traditional Chinese culture. She thinks that in general, the assumption seems to be that more knowledge can only be a good thing (both in the sense that it provides opportunities to better your material position, e.g. by passing exams to get a better job, and also in the sense that it potentially brings you closer to spiritual enlightenment in the Buddhist sense, or Taoist immortality).

Whereas in Western culture, the idea of "forbidden knowledge", "that which man was not meant to know", etc, seems to be pretty pervasive. I don't know if there's actually a continuous line of intellectual descent between the idea as it currently exists and, say, the Tree of Knowledge in the original Genesis account, but it seems like you could plausibly argue at least for continuity in medieval attitudes towards demonology and the more recent image of the "mad scientist" (both being examples of someone who's believed to so hungry for knowledge that they're willing to sacrifice their humanity to get at it).

More recently we've had Lovecraft, and the general idea that progress in ANY field of knowledge will inevitably lead to you learning something terrible which you'll be unable to live with comfortably (obviously Lovecraft was a fiction writer rather than a philosopher or theologian, but his ideas do seem to have resonated with a fair number of people). So while Western culture also frequently endorses the idea that more knowledge is a good thing (e.g. by encouraging greater and greater numbers of people to pursue tertiary education), there are definite contexts in which people become uncomfortable with that idea.

We were wondering whether the roots of this distinction might lie in the Christian idea that your relationship with God is paramount, and everything else is secondary (so that knowledge is good if it brings you closer to God, bad if it threatens to distract you or lead you astray). This would seem to be opposed to the traditional Chinese concept of deities who make certain demands on their followers, but don't seem to assume that they will or should be the immediate focus of anyone's attention 24/7. You further seem to have the concept that spiritual development based purely on knowledge is possible, rather than having a personal connection to a specific being be a necessity for the process.

I hasten to add that these perceived distinctions are highly speculative, and so are probably Just So Stories- I know virtually nothing about Chinese culture. I guess the relevant question is: can anyone here think of a Chinese story or belief system which seems to draw on the concept of "forbidden knowledge"? And if so, does that seem to be a borrowing from Western culture, or something that Chinese culture has traditionally found intuitive?
