摘要： 量化分析本质上是技术主义的方法，具有科学性与合理性，然而能否从历史的长线来对文学史现象和作家作品做出相对超越性的评价，是存有疑问和不无难度的，但它指向了文学史研究中新的理论生长和文学史文本写作的新思路。由此，在中国文学史观本质主义和反本质主义的讨论中，“阐释主体的权利”提醒我们可以有对于文学史进行个人性阐释的可能，“公共理性进步或退化”能够很好地解释中国现当代文学研究中评价尺度的变幻问题。而在中国当代文学发展过程中，公共理性最核心和最恒定的内涵只能是人性和人类性，无论是审美评价还是思想评价，都不能忽视这个基础和底线。

Abstract: In essence, quantitative analysis is a method of technicism, which is scienti?c and reasonable. However, whether we can make a relatively transcendent evaluation of literary history phenomena and writers’ works from the long line of history is questionable and not without dif?culty. But it points to the new theoretical growth and the new thinking of literary history text writing. Therefore, in the discussion of essentialism and anti essentialism of Chinese literary history, “the right of the subject of hermeneutics” reminds us that it is possible to interpret the literary history individually, “the progress or degradation of public rationality” can well explain the changing of evaluation scale in the research of Chinese modern and contemporary literature.
