This article is definitely missing an explanation on the non-material differencies in not only philosophy but also politics/government and scientific tradition. Numbers divorced from their context can be very misleading. For instance, just to illustrate my point, the Incan capital at the time of the Spanish conquest of their kingdom was reputed to be far larger than any city in Europe with an enormous and disciplined workforce. However, the Incas also lacked writing and basic science among other things. If it was a matter of mathematics and sheer numbers regarding urbanization and possibly also agricultural output of products X and Y, then the Incas would have been in a superior position to Europe and we would be justifiably dumbfounded to this day as to why Europe and not the Incas led the world into modernity.

Certain such differences existed between Europe and China, between Europe and the Islamic caliphate, between China and Japan, between India and China, etc, and they all played out in different ways and contributed into shaping the different paths many of these countries and regions have taken since, some more significant and some less. Not including these non-material differences is tantamount to avoiding the subject that this article is supposed to be dealing with...
