Environment is a good question, with two traditions pretty much conflicting in my mind - one the Jewish classical example of everyone crowding around one Torah and arguing about the meaning of certain passages, and the other the Chinese tradition I am glued into now, of sitting at your desk and memorizing the book word for word with the commentary.
The question then is, what are the two uses? One gets the job done, the other only brings in doubt - how can you get to one without the other, and which one is more affective - to know enough to discuss, you must first memorize, to discuss, you must dissect what you have memorized - with some many subjects, what time is there to either memorize, or discuss?
