Probably A Postivist Thesis Vindicated

Rise and Fall of Chinese Dynasties Tied to Changes in Rainfall: Scientific American
It is a proverbial teaching leasson in history that geography and time are the two eyes of the history. Geological knowledge advancement is helping history in redifining its thesis which is an ongoing process in history. However, I, as student of history, believe that our stress should be on the activity of man. We should ask that what actually man did in response to the climate change. That will provide us better answers. I believe Taoism may be the result of such experiences in Chinese history. In short, the question should remain confined to the activities of man. It should ask that when the given premises changed, what did the man do.
