His own table-talk, conversations, discussions and notes were compiled by his pupils, and are preserved in the work entitled in English, "The Confucian Analects," which is one of the four books constituting the most sacred portion of Chinese philosophy and instruction. He also wrote a work named "Spring and Autumn, or Chronicles of his Native State of Lu from 722 B.C., to 481[4] B.C." He "changed his world," as the Buddhists say, in the year 478 B.C., having lived seventy-three years. Primitive Chinese Faith. The pre-Confucian or primitive faith was monotheistic, the forefathers of the Chinese nation having been believers in one Supreme Spiritual Being. There is an almost universal agreement among scholars in translating the term "Shang Ti" as God, and in reading from these classics that the forefathers "in the ceremonies at the altars of Heaven and earth ... served God." Concurrently with the worship of one Supreme God there was also a belief in subordinate spirits and in the idea of revelation or the communication of God with men. This restricted worship of God was accompanied by reverence for ancestors and the honoring of spirits by prayers and sacrifices, which resulted, however, neither in deification nor polytheism. But, as the European mediæval schoolmen have done with the Bible, so, after the death of Confucius the Chinese scholastics by metaphysical reasoning and commentary, created systems of interpretation which greatly altered the apparent form and contents of his own and of the ancient texts. Thus, the original monotheism of the pre-Confucian documents has been completely obscured by the later webs of sophistry which have been woven about the original scriptures. The ancient simplicity of doctrine has been lost in the mountains of commentary which were piled upon the primitive texts. Throughout the centuries, the Confucian system has been conditioned and greatly modified by Taoism, Buddhism and the speculations of the Chinese wise men. Confucius, however, did not change or seriously modify the ancient religion except that, as is more than probable, he may have laid unnecessary emphasis upon social and political duties, and may not have been sufficiently interested in the honor to be paid to Shang Ti or God. He practically ignored the God-ward side of man's duties. His teachings relate chiefly to duties between man and man, to propriety and etiquette, and to ceremony and usage. He said that "To give one's self to the duties due to men and while respecting spiritual beings to keep aloof from them, may be called wisdom."[5]
