Do you think that the expansion of Western European cultures and the failure of Chinese culture to do the same was primarily the result of factors that were short term and related to a few people (that is, political), or long term and related to very large systems (that is, biological or intellectual)? To look at that question another way, do you think that if the Yongle emperor's successor had been a little more interested in exploration, the course of history would have been significantly changed by one man? Defend your answer.
