唐僧釋皎然不滿時人詩格卑弱、論詩未精、品藻不公，深恐詩教淪喪，曾著《詩式》一書以啟迪後學，提出頗多新穎的詩學主張。其書有專門討論創作方法，同於當時最流行的「詩格」資料；也有差異者，如專門討論某時代、某人作品的評論，又有條列詩法、提供示範詩例的詩式。由於皎然一再地肯定詩歌的價值與作用，以為「詩者眾妙之華實，六經之菁英。」而「與造化爭衡」是詩人神聖的任務，所以皎然撰寫《詩式》動機較其他唐人為高，其目的又重在啟發讀者的「天機」，自然要比其他唐人詩格有價值。因此，在我國古典詩學理論和批評領域發生過相當深遠的影響。筆者閱讀眾多現存的唐人詩格資料，發現時稱「詩家夫子」的王昌齡，其所著《詩格》、《詩中密旨》等書，他的觀點不但修正了初唐人過分張揚齊梁的詩體，同時亦修正了陳子昂、盧藏用等人一味復古的詩觀。恰好代表了從初唐過渡至中唐之關於詩法的要求。這一觀點大大開啟了皎然的詩學理論。而皎然在傳承王昌齡詩法之外，個人還有頗多推陳創新的主張。諸如主頓悟、尚傳神、重直觀、崇自然、貴通變等等，很能令人受用。因不揣學淺才陋，為文深入探究，且求教於學者專家。

Monk Shi Chiao Jan (釋皎然) in Tong Dynasty displeased with those contemporary poets, who were unrefined, unfair, and not polished in writing poetry, so he wrote a book called "Shih Shih" (詩式), trying to teach and enlighten people. At the same time he also claimed many theories about poetry. His book mainly dealt with the method how to create good poems, and criticized some poems written by other poets, the style of poems has also been discussed. With a noble motivate, he always emphasized the value and function of the poetry. His efforts could inspire all the readers. Actually, he had a great influence in the field of classical poetic theory and critical sphere. Earlier than Chiao Jan's Period, a great poet called Wang Chang Ling (王昌齡) wrote those books "Shih Ke"(詩格) and "Shih Zhong Mi Chih"(詩中密旨) which revised the old poetic style and tried to change some other poets' viewpoint not using the old style. They were Chen Chih Ang (陳子昂)and Lu Tsang Yung(盧藏用). Wang's theory definitely represented the poetic style from early Tong Dynasty to Mid Tong Dynasty. In fact, Wang's thought had a great influence on Chiao Jan. Chiao Jan not only succeeded Wang's theory, but also developed many new claims, such as clearly understanding, fully expression, respecting nature, and being changeable. The research may be not so perfect and welcome other scholars advice.
