从唐诗看古代诗歌的“无我”创作范式

文艺理论研究 2017年第1期37卷 78-88页

人们一向认为古代诗歌除了在形式上有所讲究之外,是不甚讲究其内在创作审美规则的。或者更确切地说,这种规则似乎潜移默化地存在于历代的诗歌创作中,可一时又觉得很难从中总结、提炼出来。本文通过对唐诗文本的考察,加之参考历代诗学家对唐代诗歌的认识与总结,认为以唐诗为代表的古代诗歌中的确存在有一个创作范式。这个范式大致可以命名为以"景"喻"情"的"无我"范式。把"我"隐喻到"景"中的创作范式出现在古诗中绝非偶然,它与古人那博大而雄浑的宇宙意识紧密相关。

科幻乌托邦作为科幻文学与乌托邦文学的融汇,摆脱了乌托邦的政治维度,以未来叙事整合建构了想象中的人、技术、社会与环境的多元互动关系,以此深化科幻文学的美学价值与社会意义。中国科幻乌托邦未来叙事以技术想象构建了未来美学的三种表达模式:第一,在人类主体性的多重维度中重审并强调技术、人与时间的共生模式;第二,在社会结构的变革中重审主体与情感,认识到加速社会质变了人类怀旧情感并将其发展为向过去寻求未来可能性的一次次演练;第三,在文化政治的消解中重审空间与环境,以非领地化模式重建身份认同。想象的技术发展构成了中国科幻乌托邦未来叙事的内在逻辑,即未来是一场与技术、时间、空间、人性纠缠的不确定运动,技术、时间与人的共生成就了人们对于生命永生的期待与热望。这三种未来叙事模式建构的未来审美也让我们认识到以人类命运共同体面向未来时空的必要性和重要性。

李金发诗歌中最重要的关键词是“死亡”,即他用诗歌来叙“死亡”之事,或说是“死亡”之理。他诗歌中所叙的这个“死亡”观念,并非是赓续了中国传统文化中那个“死亡”观念,而是跳出了中国文化传统,直接跃入西方现代文化,尤其是德国哲学家叔本华所倡导的死亡哲学,即“悲观的人生观”的价值理念中去。从这个意义上说,李金发不但是中国新诗史上最早领悟到西方现代主义思想和诗歌精髓的诗人,还是最早让中国新诗与西方现代哲学展开对话,甚至让其以思想资源的形式直接参与新诗的创作中。他的这一不够娴熟、意义却深远的跨学科、跨文本的融会贯通,在改变中国诗歌审美结构的同时,也引入了西方现代主义诗歌中注重哲理与冥思的传统。

科幻小说的时间叙事为文学世界打开了一扇奇异大门,线性的时间轨迹被拓展想象为多重的、循环往复的、平行的时空奇景。中国21世纪科幻的时间想象主要呈现为三种方式:线性时间想象、拟真时间想象、时间场想象。这三种时间想象表达了21世纪科幻对科技发展的反思与批判,对个体独立意识与生命意志的彰显,对身体与社会、宇宙共生关系的强调。21世纪科幻时间想象立足未来观照现实经验,聚焦身体意识与情感动力洞察宏观与微观世界,以人与世界、宇宙的共生共存想象超越现实的栓楷,以有限身体探索无限宇宙,追寻人类生命的永恒意义。

悬置本体或本体论:古典诗学话语的叙述法则

上海大学学报（社会科学版） 2024年第2期41卷 135-146页

中国古典诗学话语主要是围绕着诗歌的创作与欣赏这条轴线构建起来的,而对诗歌的那些本源性问题,譬如何谓诗歌,诗歌源于哪里等问题基本上不予以直接处理。这一构成特征并非表明古代诗论家缺乏相关的本体意识,而是说中国诗歌的本体问题一直是与哲学上的“道”或“气”紧密相关。所以对此方面的叙说,他们中的绝大多数人只能遵循着“大音希声”“大象无形”的原则。这一特殊的思维方式意味着对古典诗学话语的理解与阐释,不能只着眼于字、词的表面,而应该深入到其深层的哲学结构中。基于这一理解,从理论叙说的层面把古典诗学话语奠基时期的构成形态分解、还原出来,从而说明古典诗学话语从其开始就是一种悬置本体(论)或者说有意识地虚化了逻辑源头的特殊构成体制。
