I. This paper which is summarizing thoughts of philosophy in the Ch’in Period from 256 B.C. to 206 B.C. was written for writers already dealing with the history of Chinese Philosophy so that they might supplement the gap in this time. II. Even if the Lüshih Ch’un Ch’iu is one of the most representative materials of philosoply in this period, many thinkers including Hu Shih have neglected and regarded it as miscellaneous thought because of not being creative motivation on it. But according to the result of my study, this world rather more synthetical than miscellaneous and the ideology as well as the new political world for coming unification must have been projected. In other words, we should not ignore this product of period which is containing not only purpose but intention, especially in the field of history of philosophy. III. After unification having selected all these conceptions, which was suggested by the Lüshih Ch’un Chiu concerning moralism in Confucianism, the whole-ch’i-ism in the In Yang school and revivalism in Taoism instead of power politics in late stage of the Legalist school for ruling people, the Ch’in would have been the owner of land undoubtedly and made the most utopian era in the political history of China. IV. The important philosophical concepts dealt in this paper is epitomizing the Calendar of Twelve Months (Shih Er Chi) regaeded as the main gist in the Lüshic Ch’un Ch’iu to the political schedule or agricultural life schedule for common people. Furthermore, the emphasis in this paper is saying that politics and survival should go with the order of universal operation itself so to mean the returning to naturalism and individualism which have ever been enjoyed for primitive agricultural period out of supreme nationalism in the Legalist School. The thought in Unification of the world desired by the Lùshih Ch’un Ch’iu is involving that in opening of the world at the same time to restore everything in its original position and function. So, the main ideal in the Lüshih Ch’un Ch’iu asks for the significance of life and self-importance as a point of view in life. All the beings or behaviors must be exist for the whole life and virtue of individual life, that is, individual life be the center of all. So to speak, the conversion of value which means that the life is self-reliable body and purpose itself was evolved from the individual life being also used to means for whoever had been lord in that period. V. Finally, the political thoughts in the Lüshih Ch’un Ch’iu were not discussed in details. These are going to be dealt with the next.
