I Want to address myself to two points: why I think the study of China requires the study of its history, and why I think the proper practice of the historical profession in general requires some awareness of the history of China. I would argue that the study of change in time is the heart of the historical approach, and that for this reason, history's contribution to the study of China is intellectually legitimate and quite different from that of the more specialized disciplines; and conversely, that the general problems which historians find exciting are nowhere offered in such profuse and interesting combinations, with such abundant documentation, as in the history of China.
