科舉取士，自隋唐以來，堂為士人大展才學、服務家國的終南捷徑；下迨明清兩朝，科舉制度更為完備。八股文為科考之體式，施行長達五百年；士人循行科學以達經世濟民之途徑；於此，本文藉由明清所輯經世文以及當時經世學者對於科考所行八股文之看法，試圖瞭解經世與科舉取士之八脫文有何等形式與內容之鎔鑄；進而衍伸八股文與經世之間關係為何；此議題若經由清季樸學家劉熙載所著＜經義概＞以及與其生命之歷程作一番考察，不難發發現其對於八股文之看法自有其獨到之見解，此洵為經世觀之發皇！而八股文誠如商衍鎏曾說：「萬語千言不能發其秘，窮年累月不能究其源」，對於八股文曾在明清之際影響著千千萬萬士人之前程，進而影響整個社會生活及歷史文化，不宜棄之如敝屣，當賦予應有之評價。

　　　　　Since the Suei and the Tang Dynasties, attending the national examination Ke-ju (科舉) has been the quickest path for Confucian scholars to demonstrate their study and eventually serve their country. The Ba-Gu Writing was the major form of this examination, lasting for over 500 hundred years. The Confucian scholars "saved the world"(經世) through taking this path; therefore, this paper studies the relevant oeuvres collected in the Ming and Qing dynasties and the Views on Ba-Gu writings proffered by the scholars Liou Xi-zai and his biographical life, it's not difficult to find that he does have his own special observation. His is indeed an inspiring view on saving the world! Shang Yian-liou (商衍鎏) has this to say about the Ba-Gu writing: "A thousand words cannot dig into its secret, and a thousand years cannot get to its source." To this Ba-Gu writings that have influenced hundreds of thousands of people's lives and had tremendous impact on the history and culture of the entire social life of a time, we should correctly gauge its value instead of just giving it up as trash.
