The final conclusion of literature,represented by"the end of poetry"indicates the profound crisis that litera-ture is experiencing in the present age.The powerlessness of poetics as a form of literary study in the face of literary crisis has become an indisputable fact.While traditional poetics has endeavored to ontologically legislate for literature epistemologically,it has long neglected to give literature its due and adequate legitimacy in terms of value theory.Therefore,it is necessary to return to Kant with the issue of poetics,because Kant's aesthetic exploration of poetry builds the value of literature and art on the moral kingdom and rationality of human beings,and therefore advocates a great poetics that advances the mind and moves towards ethics,which enables poetics to complete the transformation from"sensual pleasure"to"discursive pleasure"and to advance to a more tense theory of aesthetic justice.and then go beyond the narrow sense of symbolic semantics and advance to a more tense theory of aesthetic justice,which has important enlightenment significance for people to reflect on the current literary dilemma.
