I think this is a fragment
The correct answer would be:
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
Thorough these lines from "Song of Myself”, Walt Whitman was trying to indicate that, from his perspective, all human beings were equal, irrespective of gender. That is to say, it did not matter if you were a woman or a man, all human beings were equal in the poet’s eyes.
The main event and the outcome
I would actually go with the last option based on my search, and also the first option. I feel like they would both best exemplify Descartes' break with Aristotelian thought.
