一個詩社或團體的營運要可長可遠，須有強大的共同凝聚力，《笠》從創刊至今從未間斷，歷經四十幾個年頭，在臺灣文學史上可謂異數。而《笠》之所以能夠屹立不搖，走過風風雨雨的年代，與創始之初創始者積極推動及奠定發展方向有關。陳千武從《笠》創社伊始，即扮演了重要的角色，在《笠》的營運與推動上占有重要的地位，使《笠》能夠在持續平穩中成長。此外，他注重知性、批判的詩風，在威權體制的六、七○年代，寫下許多批判力極強的「泛政治詩」，提振了《笠》的寫作精神，對《笠》早期風格的形成，具有一定的影響性。 此外，他對後輩的提攜與鼓勵不遺餘力，使得如鄭炯明、李敏勇、陳明台、郭成義、陳鴻森等七○年代崛起的年輕詩人，都曾受到的精神感召，在詩的領域向前奮進，舉起臺灣現實精神的旗幟，日後各個在臺灣文學界佔有一席之地，成為《笠》與臺灣文學重要的作家之一，此外，也推動各項的文藝活動，使《笠》與臺灣文爾的發展，能夠更加成長茁壯。 雖然，一個文學社團風格的建立，需要依賴時間的累積，及許多人的努力，才能見其端倪。但在發展之初，若成員能達成共識，且有一定的規畫與使命，配合有力人士的推動，則一個文學社團的體質能較健全，其永續發展的可行性也會增大。而《笠》創刊伊始，正因陳千武個人對文學的執著及其對文學的信念，積極地參與《笠》的各項運作，使得《笠》能夠在陳千武的奔走下，逐漸壯碩成長，發展出具臺灣特色的詩學，有著異質知性的風格。

The continuation and property of a poetry society, or poets group, always bases on the strong cohesion among its members. The uninterrupted publication of the poetry magazine, Li, for more than forty years, is an anomaly in the history of Taiwan literature. This has to do with the founders, who worked so hard to establish it and continued to support it through the years. From the very beginning, Chen Qianwu 陳千武has been a decisive figure in setting up the direction of the magazine and continued to play an indispensable role in supporting it. Throughout the years, the emphasizes an intellectual, critical stance in writing poetry, which shapes the dominant style as found in Li magazine. He, for instance, wrote many so-called “pan-political’ poems in the authoritarian 1960s and 1970s, showing a creative spirit that has come to influence many later-comers. In addition, Chen displays no reservation in encouraging such younger poets as Zheng Jiongming 鄭炯明, Li Mingyung李敏勇, Chen Mingtai陳明台, Guo Chengyi 郭成義, and Chen Hongsen 陳鴻森, who later on became the leading voice of realistic spirit in Taiwan poetry. Since Chen Qianwu has played so important role in the founding and development and has set up the philosophy and characteristics of the poetry magazine Li, this article will attempt to depict the man, his development of poetic style and his contribution to the overall development of Taiwan modern poetry.
