扬雄的审美范畴“丽”来自其审美命题“诗人之赋丽以则,辞人之赋丽以淫”,而“丽”的提出开启了“文学的自觉”理论探讨之先河。在此之前,“丽”只是偶尔被使用,到了扬雄才真正把“丽”作为审美范畴,文学自觉的标志性特征(即具有审美特性)已在“丽”中显现端倪。扬雄也为“丽”附设了“则”的政治、社会功用等制约因素。 Yang Xiong’s aesthetic category “Li” comes from his aesthetic proposition, “The Beauty of the Poets, the Beauty of the Poets and the Beauty of the Etiquette”, while the proposition of “Li” opens up the discussion of the theory of “Consciousness of Literature”. Prior to this, “Li” was used only occasionally. Yang Xiong really regarded “Li” as the category of aesthetics. The symbolic feature of literary consciousness (ie, having aesthetic characteristics) has already appeared in “Li”. Yang Xiong also “Li” attached to “the” political and social functions and other constraints.
