Which poet's writing includes the exploration of themes of identity and existence in "the Cambridge ladies who live in furnished souls"?

The correct choice for the poet whose writing includes the exploration of themes of identity and existence in "the Cambridge ladies who live in furnished souls" is indeed e.e. cummings. This poem reflects cummings' characteristic style, which often emphasizes individualism and the complexities of identity. In "the Cambridge ladies who live in furnished souls," he critiques the superficiality and conformism of certain societal norms, capturing the struggle between societal expectations and genuine self-identity.

Cummings' unique use of language and form enhances the exploration of existence and personal identity. His unconventional syntax and imagery challenge readers to engage deeply with the text, fostering a reflective examination of how identity can be shaped by external forces.

Other poets mentioned might address themes of identity but do not delve into the specific existential nuances presented in this particular poem. For instance, while W.H. Auden often explores complex emotional and social themes, his approach is typically more structured and formal, differing from cummings' free-spirited style. Gwendolyn Brooks focuses on the experiences of African Americans with a strong emphasis on community and social issues, and Matthew Arnold's work tends to engage with cultural criticism and personal disillusionment rather than the intimate, exploration of self that cummings embodies.
