縱橫象數，儒門義理──荀爽易學核心價值的重建與再定位

Re-examination of the Core Value in Yi Jing Studies of Xun Shuang: Constructing the Confucius Meaning via Phenomenon and Number

荀爽（128-190）易學歷來為人所關注的即其乾升坤降的學說，並將此視為其易學的核心觀念。順此，學者多將荀爽易學單純歸類為象數易學，並對其欲以一套不成熟的陽升陰降之象數系統解經，頗多穿鑿附會的情形多所批判。然而細究荀爽易學的內涵及其生命歷程，可以發現在乾升坤降之上，更有一套儒家經世道德思維在支撐其易學系統。身為積極入世的當代大儒，其注《易》已非僅僅為卜筮系統服務的象數易學，而是具有高度人文價值與政治意識，是一種即象數即義理的儒家道德義理系統。由此可知，其易學的核心價值應由當位居中與陽尊陰卑的道德內涵來探究，自能通透其易學的價值。也就是說，荀爽重視的是從實然到應然的道德意識轉化，我們應該更重視其得位、居中與承陽的儒家道德思維與內涵，並視為荀爽易學的第一義，而把陽升陰降視為第二義的象數方法，方可真正透顯荀爽易學的人文精神與價值。
