This study aims to figure out Bob Perelman’s view of language by examining “The Marginalization of Poetry,” one of his poetic theories written in verse, and to catch up with the way his “new sentence” works for “de-narrativization” and “re-narrativizationin” in the first two sections of a.k.a. Perelman criticizes in public that lyric poetry, in its adherence to “official verse culture,” takes its origin from the poet’s transcendental self. His idea of marginalia supports an effort to write for what is cast away through mainstream publishing, literary awards, and marketing. In a.k.a., Perelman experiments a kind of open writing in which the reader takes as much part as the author to establish possible connections between estranged sentences. Readers are left to find a “master narrative” among sentences which are juxtaposed without subordination to higher logic of paragraph. A critique of late capitalism may be a possible “master narrative” as it appears in various parts of a.k.a. It is after the poet’s “de-narrativization” that language can be exempt from invisible forces affecting us socially or culturally. It is after the reader’s collaboration that we are given a chance for “re-narrativization.”
