一、问题的提出文艺学是学科之名,名者实之虚,实者名之实,这个学科名称与学科实体原来是统一的。文艺学又是一个概念,有其概念之内涵,又有其概念之外延。文艺学概念的内涵和外延原本也是统一的。 First, the issue put forward Literature and art is the subject of the name, the real name of the virtual reality, real names, the subject name and the subject entity is the original unity. Literature and art is a concept, the connotation of its concept, but also the extension of its concept. The connotation and denotation of the concept of literary arts are also originally unified.
