蓋然性の論理学 : ライプニッツ中国学の方法論への一視点 Logic of the Probability : A Point of View Concerning the Methodology of the Chinology in Leibniz
Some Japanese Leibniz researchers have emphasized "the logic of the analogy" as the point about his chinology. This logic functions as a methodology, with which man can compare the Chinese thoughts with the European ones. But, how does Leibniz precisely judge, whether the informations that the Jesuits have send from China to him are correct? To this question, we can point out that there is the other logic in Leibniz : "the logic of the probability". Leibniz develops this logic mainly in the context of the debates on the reliability of the history, which have taken place around the end of the 17th century in Germany. In these debates, some thinkers agree with the Pyrrhonism on the history. But Leibniz objects to this point of view. He would prefer to establish the reliability of the history by suggesting different degrees about the probability. According to him, the consideration about the probability is based on a kind of calculation, whose exemplar man can find in the jurisprudence at that time. This calculation which demands the objective evidences is the essential of the logic of the probability, no less. Leibniz uses this logic not only in the field of the history, but also in that of chinology, to establish it as one of the objective and modern sciences.
