相声产生于清代中后期的北京,在市井民间的发展中,形成了开放多元的传统,蕴含着丰富而芜杂的表达资源。2.世纪50至90年代,曲艺工作者挖掘市井传统的教化价值,确立了以现实主义为核心的新曲艺传统,并使之成为一种全民族的艺术。2.世纪以来,年轻一代在市场化营销中挖掘市井传统中的狂欢化因素,重新塑造出迎合中产阶级的圈层化、符号化的传统。两种传统化实践都是从业者根植于市井传统的某些侧面的发挥,但都不完全是从社区民众主位的视角出发的,这导致在相声传承中,最广大的群体——专心于艺术的普通演员、非中产的普通观众是失语的。因而,在当下民间传统的发展过程中,有必要充分尊重民间的力量,使民间能掌握自我表述的权利。

元明之际浙东文人的文学史观与复古旨归

元明之际,浙东文人的文学复古与立身志意融合统一。首先,浙东文人以体、法浑融的三代之文为起点,建构起宗经、尊古而审时的文学史观,“文”的历时叙述与“时”的现实关切紧密结合。其次,浙东文人聚焦古律之变,提倡诗歌音调的尚古。尊尚... 详细信息

元明之际,浙东文人的文学复古与立身志意融合统一。首先,浙东文人以体、法浑融的三代之文为起点,建构起宗经、尊古而审时的文学史观,“文”的历时叙述与“时”的现实关切紧密结合。其次,浙东文人聚焦古律之变,提倡诗歌音调的尚古。尊尚古体诗的创作风气与讲求协和音调、反对诗歌律化的理论旨趣相辅相成,寄寓了浙东文人的政治理想。再次,浙东文人的立身志意与文学正变观念相互交织,君子之志彰显文学师古的主体价值,形成“人”与“文”的精神同构。最后,“流而为文人”、正变诗风、复古气象等论说,关涉明代文学复古路径的意、辞分衍。元明之际,浙东文人的文学复古与明中后期转向审美化、精细化的文学复古存在显著差异。

人性论是儒家哲学的核心问题,其随着历史发展演变出不同内涵、呈现不同特点。孔子认为生之谓性。孟子进一步分辨其中的善恶,以善质为性。荀子反之,以恶质为性。汉儒综合孟荀,认为性善恶混,魏晋唐儒家也持这种观点。宋明理学将人天生之物分为两类,即形而上的性和形而下的气。形而上的性是超越的,为理想人生奠定合法性基础;形而下的气有清浊之分,为道德教化提供存在论基础。而从先秦到宋明的儒家教化,人性作为存在的主体,由最初的自然性气质活动,逐步转化为存在性的超越活动,在这个过程中,感应是一以贯之的原理。

抒情与叙事构成明末清初文体观念破立演变的双重内核。首先,抒情是建构文体史观的主轴,将文体演变之“势”归于“情”,彰显不同文体的抒情特质,为推尊新兴文体奠定了理论基础。其次,情事融构的文学纪史导向,促进了以高行卑的“顺向”破体。诗史、词史、曲史等创作实践,既强化了文学纪史的民间立场与共情表达,又刺激了诸体叙事性的扩张,史传文法向诗、词、曲的迁移是其重要表征。最后,叙事文法的雅俗互渗,驱动着自下而上的“逆向”破体。俗文学的兴起和文学话语权的下移催生了以传奇手法为诗、“以小说为古文辞”等文体实践,有力冲击了文体的尊卑秩序,映射出文学世俗化进程中的体用新变。抒情与叙事传统、雅俗文体观念在明清之际的融会,促成了清代诸体繁荣的古典文学“终章”。

“东南二老”的诗歌观念体现出康乾之际诗学承续转变的复杂特征。诗歌面目论强调宗法贵在神理、自成面目,“以人论诗”突破“以时论诗”的阐述模式,重构个人创作与诗歌典范的关系。诗歌新面目的建立关涉风格、性情、手法等命题。神韵诗风在流衍后期陷入单一虚泛的困境,沈氏以诗选编纂、钱氏以创作实践积极开拓诗歌风格的取径,引导诗风多元化发展。二人倡扬性情诗论,性情诗论的社会性维度强化政教功能、个体性维度突出诗歌表现之“切”,两者产生庙堂化、私情化的异趋。以文为诗的创作风气深化了诗文之辨,对诗歌的赋比兴手法、议论功能、创作主体身份等话题的论说折射出诗人、文人与学人之诗的殊途。
