I have to write an essay on the significance of the green light being hope for the future and Gatsby's dreams
My thesis statement is incomplete however because I only have two body points.
one is it symbolizes Gatsby's love for Daisy
two being Gatsby realizes who Daisy really is
and I can't think of a third one?
Concerning The Great Gatsby, the green light at the end of Daisy's dock represents Gatsby's closeness to his dream. He can actually see where Daisy lives after five years of dreaming about her. He spends time nights just staring at the light.
I'm not sure what you mean by the line in your question about Gatsby realizing who Daisy is. He is in love with her until the end. She chooses not to go with him, but his love never changes. Even after she chooses Tom and hits Myrtle and lets Gatsby take the blame, he stays at her house like a peeping Tom to make sure Tom doesn't hurt her. Then he waits for a phone call from her the next day.
Again, the green light demonstrates how close Gatsby is to his dream. The light is so close, and yet so far, as the cliche goes.
