  • Matteo Ricci and Xu Gwangqi translated the first six Books of Euclid's Elements and published it with the title Jihe Yuanben, or Giha Wonbon in Korean in 1607. It was brought into Joseon as a part of Tianxue Chuhan in the late 17th century. Recognizing that Jihe Yuanben deals with universal statements under deductive reasoning, Jo Tae-gu completed his Juseo Gwan-gyeon to associate the traditional mathematics and the deductive inferences in Jihe Yuanben. Since Jo served as a minister of Hojo and head of Gwansang-gam, Jo had a comprehensive understanding of Song-Yuan mathematics, and hence he could successfully achieve his objective, although it is the first treatise of Jihe Yuanben in Joseon. We also show that he extended the results of Jihe Yuanben with his algebraic and geometric reasoning.

  • Scholars of new religious movements have emphasized the role of "second founders," such as Judge J.F. Rutherford for the Jehovah's Witnesses, Brigham Young for the Mormons, or Deguchi Onisaburo for Oomoto. They systematize and structure movements often created by the "first founders" with a minimal organization only. The paper argues that the model for the sequence first founder/second founder described by these scholars is the relationship between Jesus and Paul of Tarsus at the origins of Christianity. It proposes a comparison between Jesus of Nazareth and Kang Jeungsan, who established the tradition leading to present-day Daesoon Jinrihoe. It then summarizes the biography of Jo Jeongsan, recognized by Daesoon Jinrihoe as its "second founder" within the same tradition, and discusses the analogies between his connection to the "first founder," Kang Jeungsan, and the connection Paul of Tarsus established with Jesus Christ. The paper considers recent scholarship about Paul, often described as the "New Perspective on Pauline Scholarship." Paul never personally met Jesus Christ, except after the latter's death through a spiritual revelation, just as Jo Jeongsan never met Kang Jeungsan, except after his death, when he manifested himself to him in spirit. Nonetheless, Paul was able to decisively shape the largest branch among the followers of Jesus Christ, just as Jo Jeongsan originated the lineage leading to Daesoon Jinrihoe, currently the largest religious order among those recognizing Kang Jeungsan as the incarnated Supreme God.
