* Literary Lineage: Whitman is considered the father of American poetry, particularly for his free verse style and celebration of American life. Ginsberg saw himself as a direct descendant of this tradition and felt a strong connection to Whitman's legacy.
* Shared Vision: Both poets share a common interest in exploring the complexities of American society and the search for individual identity. Ginsberg's use of "dear father" implies a sense of shared purpose and understanding.
* Homosexuality: Both poets explored themes of homosexuality in their work, though it was more explicit in Ginsberg's poetry. The term "father" could also carry a symbolic weight, referencing a paternal figure who embraces and validates the speaker's sexuality.
* Spiritual Guide: Whitman's work often explored spiritual themes and a connection to nature. Ginsberg, grappling with his own spiritual anxieties, might be looking to Whitman as a guide or mentor.
* Critique and Conversation: The poem is also a dialogue with Whitman, with Ginsberg using the "supermarket" as a symbol of American consumerism and the alienation it creates. He imagines Whitman walking through this modern landscape and questions his reaction to it. This creates a dynamic conversation between past and present, tradition and modernity.
Ultimately, the use of "dear father" is complex and multi-layered. It reflects Ginsberg's reverence for Whitman, his desire to connect with his literary heritage, and his exploration of his own identity within the context of American society.
