“Twixt Devil And Deep Sea”:William Empson As Poet-Critic, Essam Fattouh Feb 2021

“Twixt Devil And Deep Sea”:William Empson As Poet-Critic, Essam Fattouh

BAU Journal - Society, Culture and Human Behavior

This paper attempts to offer a fresh examination of the relationship between Empson’s early career as a poet and his later erudite, largely influential, critical output. The theme of waste, which dominates his Collected Poems, partly accounts for his decision to abandon poetry, and invest his interest in complexity and ambiguity in a modernist/postmodernist procedure, way ahead of contemporary literary theory at the time. The theme of waste is further highlighted through readings of crucial key poems, as several critics of his time, such as Leavis and Alvarez, accurately signaled. The Empson canon is, thus, enriched, inviting the application of …
