文学理论通常显现为一批命题和一套观点的集合。这些命题和观点的阐述对象是文学,具体的考察围绕作家、作品、读者形成三个不同部落。许多时候,文学理论试图发现文学内部隐藏的各种公约数,例如母题、原型、叙述模式,读者的期待视野,如此等等。如果意识到不计其数的作品拥有众多繁杂的形态,这种归纳犹如披沙拣金。相对于归纳的聚焦,延展是文学理论的另一种工作模式。追 Literary theory often appears as a collection of propositions and sets of ideas. These propositions and views elaborated on the object of literature, the specific investigation around the writer, works, readers formed three different tribes. Quite often, literary theory seeks to discover the various covert divides hidden within literature, such as motifs, archetypes, narrative patterns, the expectations of readers, and so forth. If you realize that countless works have many complicated forms, this kind of induction is like Pishang gold. Compared with the focus of induction, extension is another mode of operation of literary theory. chase
