施蛰存被誉为“中国现代派文学”的重要开创者，其小说创作融合了西方精神分析学派的思想资源和中国古典文学的题材资源。本文从创作诗学的维度出发，以施蛰存小说的爱欲叙事为研究对象，基于文本细读，重点分析象征、突转和升华等艺术手法在爱欲叙事中是如何展开的。第一章探讨了爱欲叙事的象征机制及其物质基础，从物象、动作和话语三个层面揭示施蛰存如何通过隐蔽的象征机制捕捉到爱欲的普遍意义；第二章以亚里士多德的诗学理论为依据，分析爱欲叙事的突转，以及这种突转手法的诗学意义；第三章重点研究爱欲叙事的升华，指出施蛰存通过内容、形式和意义三个不同层次的升华手法的出色发挥，在不同时期不同程度地完成小说的整体性创造，并在小说创作的最后阶段，写出以《黄心大师》为代表的完成度最高的精品力作，展现施蛰存小说非凡的诗学价值。通过对爱欲叙事的研究，本文也初浅探讨施蛰存终止小说创作的内部原因：他以否定性升华完成对爱欲主题的超越性书写，一颗暗流涌动的诗心也归于平静了。

Zhecun Shi is regarded as an important pioneer of "Chinese modern literature".His novels integrated the methodology of Western psychoanalytic scholars into the themes of Chinese classic literature. Starting from the perspective of writing poetics, this paper regarded the erotic narrative in Zhecun Shi’s novels as the subject of research. Based on the intensive reading of works, this paper put its emphasis on the artistic technique of erotic narrative, such as symbolize, abrupt transform, sublimate and so on. The first chapter expounded the mechanism of symbolic description for erotic narrative, revealing how Zhecun Shi interpreted the universal significance of Eros implicitly from the angles of objects, action or discourse. The second chapter analyzes the abrupt transformation in the erotic narrative and the poetic significance of this abrupt transformation’s technique, based on the poetic theory of Aristotle.The third chapter was focused on the sublimation of erotic narrative. By making a good use of sublimation techniques at the level of content, form and significance, Zhecun Shi finished the composition of novels to various degrees in different eras. At the last stage of his writing, Zhecun Shi finished his masterpiece “Master Huang Xin”, which was the best work, became the representative of his works, and showed the extraordinary poetic value of Zhecun Shi’s novels. After an analysis on the erotic narrative, this paper offered an insight into the internal motivation that caused Zhecun Shi to stop composing novels. He completed his transcendental writing on the theme of erotic desire with a negative sublimation, then his surging poetic heart returned to peace.
