Abstract: Chinese and western literary theories have different opinions on the issue whether the life ontology of literature is the materialized form of literary existence or it is another life born under the materialized shell.The materialized form of literature can be described as the poetic language.In the pre-literary "infant period",the potential and the organic nature of poetry are implicitly collected.Without the "voice" of poetry,literature has nothing to rely upon.However,the poetic language is not the life of literature.Since the birth of the poem,images,emotions,events,pictures,bodies,etc.have appeared one after another with the help of language but tenaciously rejected the presence of language.The extremity is characterized by the fact that literature at the age of digitization has given little care to language,so what determines the foundation of literary life becomes the core issue of literature.This paper proposes that the ontology of literature appears as a complete sequence of life presented in poetic language.Before and after the poetic language presents the mystery of the presence and absence of poetry,and the life itself undergoes inherent variation along with the presentation of poetic language.The presence of words,ideas,divinations,images and the like vary inversely with the logical phase of the composition of literature,so that the literature in the digital age can ingeniously introduce the subsequent genesis of literature into a wide field of life,changing the way of poetic language bearing in traditional literature to stimulate the object.In this way,the complete life of the poetic language is also transformed from the gradual attenuation of the external materialized representation to the subject's congenial mutation and renewal.

Key words: literature, life ontology, poetic language, life mutation, field of life
