魏晉卦變說析論

The Study of GUA-BEIN (封變) in the Wei Jin Period

卦變的思想雖源自於荀爽，而真正的卦變體例應始自虞翻，再由姚信、蜀才逐漸開展，然後才有後世各種卦變理論的產生。然因這時期的《易》注常因亡佚不全而導致研究不易，故筆者逐一考辨清人對魏晉諸家所輯佚的卦變條文，審察其對錯曲直，藉此說明魏晉時期卦變易例的發展脈絡，並證明虞翻、姚信、蜀才等人的卦變學說具有「一爻動，二爻交易」、「某卦本於某卦」的理則，對於後人主張「推卦之所由來」、「某卦從某卦變來」的卦變理論確實產生啟發作用。本文內容大約有四個要點：（一）界定「卦變」涵義，推閘易家所謂的「推卦之所由來」、「某卦從某卦變來」的理論，並證明這是魏晉封變說的理論基礎。（二）清楚闡述虞翻卦變說的發展狀況及其變例、違例之處。（三）找出姚信、蜀才對虞翻卦變說的補正，同時也表達自己與學者不同之見。（四）最後總結並還原魏晉卦變說的真實面貌。本文擬從這幾個要點來作探析。

GUA-BEIN (封變) is one of the most important issue of Yi-ology's history in the Wei Jin period, and there are various theories developed in the following dynasties.
