Abstract: Western cultural context of modernity,just forming and characteristic of the secularization and de-religion,has delimited the constructional domain of the western modern literary theory.Under this cultural atmosphere,the course of modernity is like a scientific paradigm and a knowledge pattern;among it,all of questions:the deterioration of transcendent field,the establishment of human subjectivity,the self-discipline of literature and arts,the salvation of present life,the science and the scientificalness and so on,constituted main topic of the western modernity poetics construction.Exploring the modernity poetics thoroughly will be of great benefit to excavating impetus source of the western modernity poetics formation,and provide the reference or the lesson for further construction of the modernity poetics.
