本文論題：《文心雕龍》「文體通變觀」，實屬「龍學」研究之熟題，然本文從「後設性」研究進入，一方面以「後設詮釋」來解讀《文心雕龍》，另一方面從「後設批評」來反思近現代學者研究《文心雕龍》「文體論」與「通變觀」的問視視域。進而反思從事《文心雕龍》研究的兩個思考面向：一是，論「通變」必須將其限定在六朝「文體」觀念中，較能貼近劉勰創作《文心雕龍》的原意。二是，論「通變」時若忽略其所隱含的「辯證性」觀念架構，將很難貼近劉勰是在辯證思維下所規創出的文學理論，以及建構其「結構歷程」的動態文學觀。準此，本文以「問題視域」為研究視角，將焦點集中在反思近現代學者「文體通變觀」研究成果的問題視域，以重新檢視劉勰《文心雕龍》理論體系的基礎性觀念，期能為「龍學」研究找尋另一種可供思考的新視域與新方法。

”Wen-ti-tong-pien-guan” of Wen-shin-diao-lung is a hot topic for research belonging to the category of ”studying on lung.” Taking an overview, however, on the ”problematic vison of the research results of modern scholars,” the author opines that there are still another two topics that deserve re-thinking, one is that when discussing ”tong-pien,” one has to limit the discussion within the context of ”wen-ti” of the six-dynasty in order that the results are in accordance with the original intention of Wen-shin-diao-lung by Liu Hsieh; the other is that when discussing ”tong-pien,” one has to pay close attention to the potential ”dialectical” structure in order to be in accordance with Liu Hsieh's literary vision of ”structural process” implicated by dialectical thinking. Therefore, this paper, on the bases of ”problematic vision,” will focus on the retrospective exploration of the problematic vision of the research results on ”wen-ti-tong-pien-guan” achieved by modern scholars. The purpose of this exploration is to re-examine the basic ideas of the structural system of Liu Hsieh's Wen-shin-diao-lung, in the hope that a brand-new vision will be found for the ”study on lung.”
