Sun Yat-sen (in his teachings) completely includes the true ideas of China as they recur again and again from Yao and Shun, Confucius and Mencius. It will be clear to us, therefore, that Sun Yat-sen is the renewal of Chinese moral culture, unbroken for two thousand years ... we can see that Sun Yat-sen was convinced of the truth of his own words, and at the same time we can also recognize that his national revolution was based upon the re-awakening of Chinese culture. He wanted to call the creative power of China to life again, and to make the value of Chinese culture useful to the whole world, and in that way to realize cosmopolitanism.(89) Accordingly, Sun Yat-sen’s doctrines may not only be regarded as having been based upon the tacit premises of the Chinese intellectual milieu, but as having been incorporated in them as supports. Sun Yat-sen’s theories were, therefore, consciously as well as unconsciously Chinese. Sun Yat-sen was proud of the accomplishment of the Chinese in physical and applied knowledge. He praised Chinese craftsmanship and skill, and extolled the talents of the people which had invented the mariner’s compass, printing, porcelain, gunpowder, tea, silks, arches, and suspension bridges.(90) He urged the revival of the talents of the Chinese, and the return of material development. This teaching, in conjunction with his advocacy of Western knowledge, leads to another suggestive point. Sun Yat-sen pointed out that _wealth_ was to the modern Chinese what _liberty_ was to the Europeans of the eighteenth century—the supreme condition of further progress.(91) The way to progress and wealth was through social reorganization, and through the use of the capacities of the people. It may be inferred, although it cannot be stated positively, that Sun Yat-sen measured wealth not merely in metals or commodities, but in the productive capacities of the country, which, as they depend upon the labor skill of the workers, are in the last analysis cultural and psychological rather than exclusively physical in nature.(92) China, following the ancient morality, conscious of its intellectual and social heritage, and of its latent practical talents, needed only one more lesson to learn: the need of Western science. Western Physical Science in the New Ideology.
