Walt Whitman

Walt Whitman was born on Long Island, New York in 1819, and worked variously as a printer, teacher, journalist and newspaper editor before self-publishing, in 1855, the first edition of Leaves of Grass — a slim collection of twelve untitled poems, printed at his own expense, that broke decisively with the formal, rhymed conventions of contemporary American and English poetry in favour of long, unrhymed, incantatory free verse lines.

Whitman continued revising and expanding Leaves of Grass for the rest of his life, publishing six increasingly substantial editions between 1855 and 1892 — treating the book less as a finished, discrete work than as a living document meant to grow and change alongside his own continuing development, a genuinely unusual approach to authorship that he described as inseparable from his own personal and spiritual growth.

Whitman served as a volunteer nurse during the American Civil War, an experience that deeply shaped his later poetry's engagement with mortality, the body, and democratic fellowship across social difference. He died in Camden, New Jersey in 1892, having lived to see Leaves of Grass grow from a self-published curiosity dismissed by many contemporary critics into a work recognised, within his own lifetime, as a genuine American literary landmark.

The 1855 poem now known as Song of Myself makes Whitman's central mystical claim most directly: the poem's speaking 'I' is simultaneously an ordinary individual person and, without contradiction in the poem's own logic, identical with the entire cosmos, the whole of American democracy, and every other person the poem addresses — 'I am large, I contain multitudes' being perhaps its most famous single articulation of this expansive, boundary-dissolving identity claim. This is not metaphor deployed loosely for poetic effect; Whitman's biographers and critics have consistently read the poem as recording, or attempting to induce, a genuine mystical experience of dissolved individual boundary comparable to descriptions found across world contemplative traditions.

Later psychologist and psychiatrist Richard Maurice Bucke, who knew Whitman personally, went on to write the influential 1901 book Cosmic Consciousness, explicitly citing Whitman as one of history's clearest examples of a specific, describable higher state of awareness Bucke argued was becoming more common across human evolutionary history — directly crediting Whitman's poetry as both an instance and a genuine articulation of this state, a framing that significantly shaped how later 20th-century psychology and comparative mysticism would discuss expanded or unitive consciousness.
