Stephen Crane

I saw a man pursuing the horizon;
Round and round they sped.
I was disturbed at this;
I accosted the man.
"It is futile," I said,
"You can never -"

"You lie," he cried,
And ran on.

Stephen Crane - I saw a man pursuing the horizon
"A man pursuing the horizon," is an excellent example of naturalism.  I like it how the man does not give up hope of fulfilling his dream no matter what happens,  Also,  the man is foolish for not recognizing that it is impossible to catch the horizon, and is therefore wasting his life.  This poem is about a man pursuing his dream and run towards a better horizon for mankind.
