On his last night in West Egg before moving back to Minnesota, Nick walks over to Gatsby’s empty mansion and erases an obscene word that someone has written on the steps. He sprawls out on the beach behind Gatsby’s house and looks up. As the moon rises, he imagines the island with no houses and considers what it must have looked like to the explorers who discovered the New World centuries before. He imagines that America was once a goal for dreamers and explorers, just as Daisy was for Gatsby. He pictures the green land of America as the green light shining from Daisy’s dock, and muses that Gatsby—whose wealth and success so closely echo the American dream—failed to realize that the dream had already ended, that his goals had become hollow and empty. Nick senses that people everywhere are motivated by similar dreams and by a desire to move forward into a future in which their dreams are realized. Nick envisions their struggles to create that future as boats moving in a body of water against a current that inevitably carries them back into the past.
