民國初年孫德謙承繼清人駢文論述的遺緒，不僅是駢散之爭的調和者，也可說是清代以降駢散合一論的重要總結者。他認為以駢／散來判定文章優劣之看法，對駢體並不公允，也與歷史發展事實不合，是故反對嚴格畫分駢散。因此孫德謙以駢散兼行者為正格，闡揚駢散合一之論，極力彰顯六朝文的典範價值及獨特性，駢散合一也成為《六朝麗指》一書論述之核心觀點。 本文以《六朝麗指》「駢散合一」之論為研究著眼點，期能先梳理這一文章理論議題的歷史發展脈絡，進而闡析其理論內涵，並尋繹其學術意義。就理論內涵而言，本文一方面從孫氏所揭示駢散兼行以「氣韻」勝，能兼具「疏逸」與「清晰」的行文特點，以具體凸顯六朝駢體足為師法的典範價值；另一方面則從孫氏辨體之立場著眼，針對其有關駢體義界及所謂「正格」之釐清，以理解孫氏欲為駢體澄清長期被視為僵滯病癥的用心。另就孫氏駢散合一理論之學術意義而言，本文則主要歸結出具有修正文學史觀、推進駢文文學研究及為現代文學創作與發展開拓衢路等方面的學術意義。

Sun De Qian succeeded to the discussion of the relationship between paralleled prose and prose in early 20th century of China. He praised the Six Dynasties’ article as the model of paralleled prose with a definite standpoint. He thought that the Six Dynasties’ paralleled prose had its own unique style; it is unfair to merely judge from sentence form and even to distinguish the literary work between superiority and inferiority. It is also contrary to the history development fact. Therefore, he advocated the union of paralleled prose and prose theory to exalt the value of the Six Dynasties literature and list it as the key point of the “Liu Chao Li Zhi”. He is not only the one to harmonize the argument between paralleled prose and Prose but also the one who summarized it. The thesis takes the “Liu Chao Li Zhi” s union of paralleled prose and prose theory as a research core. Hope I can analyze the theory from the article issue’s thread of thought and to explain the academic significances. As far as the theory is concerned, this thesis highlights the value of the Six Dynasties’ paralleled prose which is enough to model, according to the feature writing style that Sun had revealed. On the other hand, differentiating literary style from Sun’s standpoint to understand his intention of clarifying the paralleled prose had been considered as a sickness of stubborn form for long-term. In sum, conclude form Sun’s union of paralleled prose and prose theory, it had the meaning on academic that correcting the viewpoint of Chinese literature history, to advance the research on paralleled prose and also provide more possibilities for modern literature creation.
