Science has been regarded as a body of knowledge. According to this view, there are two approaches toward the relationship between Confucianism and science: one is the subalternation of science of Confucianism, the other Confucianism is of no advantage to the development of modern science. The purpose of this paper is not to solve the disputation between these two approaches, but to take the history of science as a new approach to the problem of the relationship between Confucianism and science, since the history of science has expanded the domain of science by including its socio-cultural process. As far as the transmission of western learning (including scientific knowledge) into China by Jesuits in late Ming and early Qing dynasties is concerned, by taking Neo-confucianism's position, recent scholars usually asked: whether the learning of ang Yang-ming and his followers or that of Chu His and his followers was in favor of the transmission of western scientific knowledge? In this historical study the author finds that: if one can follow Jesuits' position, he will comprehend that in the True Meaning of the Lord of Heaven (天主實義) Matteo Ricci not only introduced scholastical philosophy by means of Neo-Confucian's them-Ke-Wu quong-li (格物窮理), but also change the relationship among Wang, Chu, and western scientific knowledge.
