本文探讨了清朝文论家刘熙载《艺概》中美学概念“虚与实”相互制约、相互补充、相互依存的辩证关系,以及在艺术和写作技法上的应用。对“无中生有”、“异形而同品”、“艺术通感”等概念进行了独到的诠释;并对刘熙载关于虚实关系存在的两种情形和其运用的限度加以述评。 This article explores the dialectical relationship between the concept of aesthetics and the concept of “imaginary and real” in Liu Xizai ’s “art summary”, which are mutually restricted, supplemented and interdependent, and their application in art and writing techniques. It gives a unique interpretation of such concepts as “nothingness,” “alienation and identity”, and “artistic sense of sympathy.” It also reviews Liu Xizai’s two situations and the limits of their application.
