What are some similarites and differences between Walt Whitman's "Song of Myself" and Ralph Waldo Emerson's "Self Reliance"?I actually already did...

I would say that it would be appropriate to focus on the time period or literary movement in which both works are immersed.  Both works help to enhance the notion of self within literature.  The idea of exploring the subjective experience as a way of gaining more insight into the world around us is of vital importance to the movement, and something upon which both Whitman's work and Emerson's writing places emphasis.  Both works are part of a movement that praised and valued emotions and the emotional exploration of self as critical to understanding in the world.  This is not a literary movement that sought to explore objective truth through science or rationalism, but rather did so through the idea of self and what that entails.
