整體與單元：百回本《西遊記》敘事矛盾現象因由蠡測

《西遊記》書中每一個單元故事，都是在「西天取經」的主題下展開陳說。這些故事的主要結構，都是由相同人物面對相同故事主題，其中不免會有許多相類的文字陳說出現；加上每一個單元故事的獨立特性，在編輯者匯聚成書之後，倘若是未能妥善處理，則故事內容上的相互矛盾及前後情節發生牴觸，都是可以想而知之的事。目前在無直接相關資料可資比對的情況下，對於造成其事之可能原因，只能採取「以果推因」的策略，根據所見文本之故事內容，參酌小說之書籍特性以及該書之形成過程來加以推測，進而蠡測出造成此一現象的諸多可能原因。本文以三事為例，說明這些看似矛盾與不合理現象下的文本內容，是否存有可以被合理解說的詮釋空間，其後再就此類現象的出現因由進行蠡測。

The episodes in The Journey to the West follow the theme of“obtaining the Scriptures from the West.”With the same characters repeatedly facing similar challenges, narrative inconsistencies are inevitable unless carefully edited. These contradictions arise when viewing the novel as a whole, though each episode remains self-contained. Without a known pre-text for comparison, scholars analyze the novel in its entirety rather than by episode, complicating its evaluation. The lack of a clear source makes it difficult to determine whether these conflicts stem from the book’s formation or editorial choices.This paper examines three episodes to explore whether these contradictions allow for reasonable interpretation and investigates their underlying causes, proposing a theory on how and why they occur.
