The lines come near the end of Song of Myself, in section 51 of the 52 sections of the final edition. In the 1855 first edition the poem was unnumbered and ran straight on from one passage to the next.
I celebrate myself, and sing myself, / And what I assume you shall assume, / For every atom belonging to me as good belongs to you.
I hear America singing, the varied carols I hear,
I loafe and invite my soul, / I lean and loafe at my ease observing a spear of summer grass.
A foolish consistency is the hobgoblin of little minds, adored by little statesmen and philosophers and divines.
A house divided against itself cannot stand.
The rank is but the guinea’s stamp, / The Man’s the gowd for a’ that.
