“时光瞬间”是华兹华斯在《序曲》中提出的一个诗学概念,也是《序曲》及华兹华斯其他若干诗歌的叙事结构。本文试图从浪漫主义反讽的角度探讨“时光瞬间”的认识论内涵。“时光瞬间”展示了记忆对感性经验的塑造作用,情感作为认识途径的局限性及自我身份构建过程中“两种意识”造成的自我异化,反映出诗人对乡村与城市、感情与理性、自然与意识等问题的认识具有明显的矛盾倾向和反讽特点。 “Moments of Time ” is a poetic concept that Wordsworth presented in the Overture, and also the narrative structure of the “Overture” and several other Wordsworths poems. This essay attempts to explore the epistemological connotation of “Time Instant” from the perspective of romantic irony. “Time and Moment ” shows the shaping effect of memory on the experience of sentiment, the limitation of the way of knowing as the way of understanding and the self-alienation caused by the “two kinds of consciousness” in the process of self-identity construction, The understanding of issues such as rationality, nature and consciousness has obvious contradictory tendency and ironic features.
