Ezra Pound is well known to have been the leading founder of modernism in English poetry in the first half of the last century. Although he seems to have languished in the shadow of postmodernism, he has now a dominant tradition which is often called ‘a Pound tradition’ in modern American poetry. The purpose of this paper is to clarify what it is that makes Pound exert a lasting influence even in the postmodern age. Pound`s modernist poetics has the triangulate relation of the poet, the literary work, and the reader. First, the poet is an artist who aims at the scientific precision of his poetry, which is an artifact composed of images presented by the ideogrammic method or the presentative method. He never has the authority to obtrude his opinion, comment or explanation in the poetic process. Instead, he should be disciplined or depersonalized enough to maintain the artistic integrity or honesty which is prerequisite for the precision and objectivity of his poem A well-disciplined poet can only juxtapose poetic materials such as images, facts, of particulars without any logical connection or narrative continuity. In consequence, poetry has gaps or indeterminacy from the narrative discontinuity of paratactic structure. And readers are required to think about the leap in the gaps from the lack of the logical connection. As a co-creator, they cannot but mobilize their maximum available imagination and knowledge. Pound`s poetics is ultimately intended to arouse readers from their mental laziness induced by familiarity with the monolinear logic of the traditional narrative and make them take an active participation in operating the latent form of a poem. Readers should not expect to follow the logical conclusion of the poet, but observe poetic materials and think about them on their own. As a modernist, Pound paradoxically has proposed the open form which admits of subjectivity and relativism in reading a poem. He foresaw the role of the reader as emphasized in the postmodern age.
