Must poetic form be, as Yeats demanded, "full, sphere-like, single," or can it accommodate the "impurities" Yeats and his Modernist generation found so problematic? Sixty years later, these are still open questions, questions to which Marjorie Perloff addresses herself in the essays collected here. The first group of essays deals with Pound's own poetics as that poetics related to two of his great contemporaries, Stevens and Joyce, as well as to the visual arts of his day. The second group deals with the more technical aspects of verse and prose. In the last four essays, Perloff takes up broader issues, including the current pessimism about the state of poetry, and the work of experimental poets and conceptual poets.
