This document summarizes Harold Bloom's theory of poetic influence and anxiety of influence. Bloom believes that poetic history is indistinguishable from poetic influence, and that strong poets overcome their anxiety of influence from predecessors through six revisionary ratios: clinamen (correction), tessera (completion), kenosis (discontinuity), daemonization (counter-sublime), askesis (purgation), and apophrades (return of the dead). The document provides examples of how Bloom views the influences on and works of poets like Wilde, Wordsworth, Shakespeare, and Stevens in light of his theory of anxiety of influence.
