苏童擅长用“爱欲叙事”建构一个善恶混杂的“人性空间”，人性论在文革后的新时期文学中再次复苏，苏童的特质在于能从“爱欲”角度深入思考人性的灰色地带。每个人都有爱欲，但当主体的爱欲处于极度匮乏和充溢的状态时，很可能激发人性中恶的部分，使人变得自欺、冷漠和不义，使社会缺乏邻人之爱。“爱欲叙事”一方面让人性之恶意识到自身的缘由，另一方面与社会中真正的罪恶展开对抗。

      论文从人物特质、结构形态和语言表征三个方面分析苏童小说的爱欲叙事。首先，在人物特质上，苏童小说关注匮乏型、充溢型和空心型爱欲主体。匮乏型人物处于爱欲被压抑的境地，充溢型人物被欲望吞没，枫杨树乡系列中不少人物实际是社会欲望机器旁边剩余的肉，空心型人物是了无爱欲的人，冷漠是其属性，主体已然丧失；其次，在结构形态上，苏童小说从个体、家和集体维度分别建筑了三种叙事结构，解构了善和恶、爱欲和死欲、禁忌与僭越的二元对立关系。个体的“堕落结构”中思维和行动具有割裂性，家庭的“窒息结构”是支配和让渡主体性权利的战争，体现了主体间理解的隔绝，集体利用“圈套结构”对人的爱欲冲动施以惩罚，以达到人性规训的目的；最后，在爱欲写作的语言上，分析苏童小说的言语、话语，并从三篇以强奸案为核心事件的小说思考法的语言和文学的语言。“言语”是小说中具体的句子，写香椿树街的言语具有反语、咒语和市井语的特点，写枫杨树乡的言语具有呓语、秽语和神谕的特点。“话语”联系的是说话主体的精神世界，小说在爱欲故事中暴露人性恶，人物为自己的冷漠、不义和自欺论辩。法的语言和文学的语言字面上截然不同，但法的精神和文学的精神都要不断追问人的本性，小说从爱欲方面关注了被侮辱被损害者，诗性正义是法和文学共通的理想。

      综上所述，“爱欲叙事”是苏童小说建筑“人性空间”的理念和方法，使人认识到自我本性中可能的善与恶。苏童小说多写日常生活中人对所爱者拔刀相向的故事，是精神上的孤绝和社会的冷漠不义滋生了潜藏于人性中的恶。认识恶是为了走向善，人可以利用爱欲的力量找回主体性，建设善的社会，以对抗真正的罪恶。

Su Tong is good at using "Lust narration" to construct a "human space" mixed with good and evil. The theory of human nature is revived in the literature of the new period after the cultural revolution. Su Tong is also interested in human nature exploration and can deeply think about the gray area of human nature from the perspective of "lust". Everyone has lust, but when the subject's lust is in a state of extreme lack and overflow crisis, it is likely to stimulate the evil part of human nature, make people become self deception, indifference and injustice, and make the society lack the love of neighbors. On the other hand, let the narrative of "desire for love" and "evil" unfold the real reason of their own.

This paper analyzes the erotic narrative of Su Tong's novels from three aspects: character characteristics, structural form and language representation. Firstly, in terms of character characteristics, Su Tong's novels pay attention to the lack, overflow and hollow erotic subjects. The deficient characters are in a situation where their love desire is suppressed, and the overflow characters are swallowed up by their desire. Many characters in the fengyangshu Township series are actually the remaining meat next to the social desire machine. The hollow characters are people without love desire, indifference is their attribute, and the subject has been lost; Secondly, in terms of structural form, Su Tong's novels construct three narrative structures from the dimensions of individual, family and collective, and deconstruct the binary opposition between good and evil, love and death, taboo and arrogation. In the individual's "degenerate structure", thinking and action are separated. The family's "suffocation structure" is a war to dominate and transfer the subjective rights, which reflects the isolation of understanding between subjects. The collective uses the "trap structure" to punish people's erotic impulse, so as to achieve the purpose of human nature discipline; Finally, in the language of Erotic Writing, this paper analyzes the language and discourse of Su Tong's novels, and analyzes the language of thinking and literature from three novels with rape as the core event. "Speech" is a specific sentence in the novel. The speech of toon tree street has the characteristics of irony, curse and market language, and the speech of maple poplar township has the characteristics of nonsense, foul language and Oracle. "Discourse" is related to the spiritual world of the speaker. The novel exposes the evil of human nature in the erotic story, and the characters argue for their indifference, injustice and self deception. The language of law is quite different from that of literature, but both the spirit of law and the spirit of literature should constantly ask about human nature. The novel pays attention to the insulted and damaged from the aspect of lust. Poetic justice is the common ideal of law and literature.

To sum up, "Lust narration" is the idea and method of Su Tong's novels to build "human space", which makes people realize the possible good and evil in their own nature. In Su Tong's novels, those who draw swords against those who should love each other are ordinary people. It is the spiritual isolation and social indifference and injustice that breed the evil hidden in human nature. Knowing evil is to move towards good. People can use the power of lust to recover their subjectivity and build a good society to fight against real evil.
