本文題為「動聲/同身/通神─白居易〈琵琶行〉析論」，主要藉著法國理論家呂西安‧高德曼 (Lucien Goldmann 1913-1970) 提出「發生論結構主義」作為文本的「理解」與「解釋」。白居易〈琵琶行〉歷來已有豐實的研究成果，筆者立足此基礎，期以釐析文本已存在的有意義的「意涵結構」(structure significative)，得出「動聲」之「有聲/無言」「隱/顯」「流動/停滯」、「同身」之「彼/此」「人我/物」「主人/客」、及「通神」之琵琶聲、琵琶女、白居易的精神會通，並在諸多微小結構的辯證關係裡，構出總意涵結構「聲情與物我分化又再聚合，共述漂泊與求安的寄望」貫穿全詩。呈現白居易謫居異地的離苦與思歸之情懷，並藉琵琶女及琵琶聲「發聲」與「代言」，強化白氏壓抑許久的無奈情志。
