Final answer:
The lines from Walt Whitman's 'Song of Myself' that illustrate the poet's belief in the equality of all humans are: "I am the poet of the woman the same as the man," "And I say it is as great to be a woman as to be a man," and "And I say there is nothing greater than the mother of men."
Step-by-step explanation:
The three lines in the excerpt from "Song of Myself" by Walt Whitman which indicate that all human beings are equal in the poet's eyes are:
- "I am the poet of the woman the same as the man,"
- "And I say it is as great to be a woman as to be a man,"
- "And I say there is nothing greater than the mother of men."
These lines embody Whitman's democratic ideal that celebrates gender equality and the universal importance of every individual's role in society, a theme that resonates throughout his poetry. The poet uses a colloquial and direct style to communicate his perception that all humans, regardless of gender or social status, possess inherent value.
