《蘇氏易傳》「十二消息卦」義理析論

Analysis on Twelve Signs of Information in Su's Elucidation on Changes

《蘇氏易傳》是北宋文豪蘇軾的《易》學代表作，是書揉合諸家之學，以《易》為明道之器，著眼於一切近人事、人情者立論，故素來將蘇軾劃歸於義理派《易》家。然綜觀全書，並非純就義理論說，蘇軾亦採用漢代之象數說，呈現象數、義理兼綜之博雅學風。漢人論《易》，特重卦氣說，蘇軾尤以十二消息卦為重。故本文擬從「卦配節候之卦氣模式」、「陰陽消息論人事進退」、「釋《易》兼綜義理與象數」三部分論述，由蘇軾對十二消息卦之討論，呈現東坡象數觀之一隅。

Su's Elucidation on Changes is the representative works of Su Shih's theory on Changes, who was the great writer in North Song Dynasty. This book integrates theories of various schools. Taking Changes as the tool, this book focuses on establishing doctrines for people engaged in fortune telling. Therefore, Su Shi has always been classified to the School of Doctrine. However, after making a general survey of his book, we find that he applied not only theories of the doctrine, but also those of image-numberology in Han Dynasty, hence the integration of both doctrine and image-numberology. When talking about Changes, People in Han Dynasty paid much attention to the theory of Gua-qi. Particularly, Su Shi attached great importance to the twelve hexagram of information. The paper clarifies it from the three perspectives: “Gua-qi mode used in season prediction”, “people's fortune telling based on yin and yang information theory” and “divinatory symbols illustration, image-numberology and doctrine”. Based on discussions on Su Shih's twelve hexagram of information, we aim to make a tentative study of Su Dongpo's theory about image-numberology.
