This fourth article in a six-part series correlating Kant’s philosophy with the Yijing begins by summarizing the foregoing articles: both Kant and the Yijing’s 64 hexagrams (gua) employ “architectonic” reasoning to form a fourlevel system with 0+4+12+(4x12) elements, the fourth level’s four sets of 12 correlating to Kant’s model of four university “faculties”. This article explores the second twelvefold set, the law faculty. The “idea of reason” guiding this wing of the comparative analysis is immortality. Three of Kant’s “quaternities” correspond to three sets of four gua in the Yijing: the fourfold nature of the soul in rational psychology (as substantial, simple, unified, spatially related) corresponds to gua 47, 6, 58, 10, respectively; the three “Definitive Articles” and fourth, “Secret Article”, in Perpetual Peace correspond to gua 16, 35,51, 21; and the four objective relations of law to duty in Metaphysics of Morals correspond to gua 45, 12, 17, 25.
