T.S. Eliot wrote influential essays in New Criticism, a literary theory movement that if I understand correctly tried to revive formalism and focus on close reading and the text itself, as a response to the literary criticism of the early 20th century, which had a greater focus on external resources to help in the interpretation of the text. However, T.S. Eliot is better known for his poetry. What effect did his work in the development of New Criticism have on his poetry?
