"Do I contradict myself? Very well, then, I contradict myself. I am large, I contain multitudes."

Socrates is unlike Whitman in that he looks to resolve contradictions
•
Plato thinks more along the lines of Whitman: part of me wants one thing, and part of me wants something else
•
Walt Whitman and his "contains multitudes" is just footnotes to Plato
•
that is the point of the dialogue form
•
contain contradictions by containing many people who disagree on a topic
•
Plato is doing an experiment
