Abstract

This paper determined that Hetu(河圖)-Luoshu(洛書) of I Ching are a symbol system of the moral doctrine of changes(易道) and considered Hetu-LuoshuLun(河圖洛書論) that examined in the first volume of Xici(繫辭) chapter 9. Hetu and Luoshu of I Ching are pictures being made up numbers. This paper started by asking what would want to expose through number is it. In Shuogua(說卦) Chapter 1, It said that Saint expressed Hetu-Luoshu and Guayao(卦爻) it after realized Tiandezhidao(天地之道) by himself. first volume of Xici Chapter 12 presents Hetu-Luoshu directly and characterized those as Shenwu(神物). first volume of Xici Chapter 9 treated Tiandezhishu(天地之數), from one to ten and dessert Yinyang(陰陽)․Wuxing(五行)․Sixiang(四象) that is fundamental concept of Eastern philosophy throughout Lishu(理數) of Hetu-Luoshu. Hetu attaches primary importance to five and acts as 一․六 → 二․七 → 三․八 → 四․九 → 五․十. Also Hetu expresses ‘Tiwuyonglu(體五用六)’ that is the principle, Wuxing(五行) runs by combining Yinyang(陰陽). Luoshu attaches primary importance to ten and represented Sixiang(四象)’s action of 九(一) → 八(二) → 七(三) → 六(四). Luoshu expresses ‘Tishiyongjiu(體十用九)’. Hetu and Luoshu are relationships of Tiyong(體用) each other, as both one and two. Hetu turn on five and completed with 一․六 → 二․七 → 三․八 → 四․九 → 五․十. But In ten, it becomes to Luoshu and turn on five and completed with 九(一) → 八(二) → 七(三) → 六(四) → 五. It starts action of Hetu at five again. Therefore Hetu is a picture that determined mainly with Wuxing, is an action principle of world of phenomenon from join Yinyang, but Luoshu is a pictures that determined mainly with Sixiang’s action of the way of heaven, is action before join Yinyang. In addition, Hetu and Luoshu is thing that Saint realized the principle of Shenming(神明), including the way of human(人道). Therefore noble man realizes the way of heaven throughout number and figure of Hetu-Luoshu and practices the way of human, is the way of human life.
