《詩源辯體》是明代晚期詩歌批評家許學夷（1563-1633）的一本著作，這 本著作在近年來的中文研究學界，成為重要的研究焦點。也因此原本不在臺灣通 行或流傳的各種原典版本，陸續流通；再加上中文學界對「中國古代文體學」及 「中國古代詩學」的研究成果趨於成熟。這些進步的因素，得以讓本文利用以對 許學夷的《詩源辯體》作更深入、更詳細、更精確的研究。 許學夷的《詩源辯體》既是一本對中國古代詩歌的批評著作，又兼是一本中 國古代詩歌史著作。全書以「辨體論」為方法，對中國古代的詩歌進行「體源論」、 「源流論」、「正變論」的批判與評價，最終寫成一本詩歌史著作；然而其真正目 的是在指導後代人學詩，故此著作最終的歸趨其實為「師古論」。經本文重構其 詩學體系後，大體說來即是許學夷對中國古代詩歌，依其理念而建構傳統；再憑 藉其建構出的傳統，企圖推廣其對詩歌的理想；最終再寄望後世學詩的人，能依 其詩歌理想學習詩歌創作。 Shi-Yuan-Bian-Ti is a treatise on Ars Poetica written by the poetry critic Xu Xue-Yi (1563-1633) in the late Ming Dynasty. This work has recently become a focal point in the academic world of Chinese Literature. Owing to this, the various versions of the original text which had initially withdrawn from circulation in Taiwan, started in gradual circulation again. In addition, as scholars’ devotion to the research of Chinese ancient stylistics and poetics become full-blown, that altogether enriches the scope of this thesis with depth, details and accuracy. Xu Xue-Yi’s Shi-Yuan-Bian-Ti is both a critical and historical analysis on Chinese ancient verse. The thread running through his treatise is “criticism of style and feature distinguishing,” alongside the judgment and evaluation within the interpretive frameworks of “generic criticism,” “criticism of poetic genesis and branches,” and “criticism of norm and deviation,” where an epic monograph was born. Ultimately, what Xu Xue-Yi aims for is to instruct the future generations in the art of poetry and that therefore, this discourse eventually returns to “criticism of studying poet laureates.” After reconstructing the poetic system in Shi-Yuan-Bian-Ti, we can conclude that Xu Xue-Yi’s attempt is to construct a literary tradition built upon the heritage of Chinese ancient poems, and further advocates his poetic ideals. The critic not only anticipates his descendants to study poetry in a similar vein, but to capture the zeitgeist of ancient time when writing poetry.
