In "The Great Gatsby" we learn about many different themes and ideas that are presented to us in the book. Themes and ideas are presented to us through the results of the choices and actions that the characters make in the story, ranging from Tom's adultery to Gatsby's nostalgia. A theme that Fitzgerald teaches his readers is that nostalgia (an extreme longing for the past) can cause many problems in a person's life, through the use of different literary elements found in the story. At the end of the first chapter, Fitzgerald uses symbolism to portray Gatsby's nostalgia, introducing us to the “mysterious green light at the end of the pier” that Gatsby stares at. The green light, because of its color, symbolizes Gatsby's hopes and dreams, namely the completion of his materialistic wealth through marriage to Daisy. The color green represents wealth, which is his love for Daisy, in which the color reveals to us that Gatsby's wealth would be complete, when he finally manages to convince Daisy to marry him. As stated above, the green light is the first symbolic representation of Gatsby's nostalgia, that is, his love for Daisy and his dream of marrying her to complete his wealth. Towards the end of chapter 6, the author uses arrogance to highlight the nostalgia and disappointment expressed by Gatsby, even after being told that he cannot change the past. When Nick tells Gatsby, "you can't repeat the past", Gatsby responds to Nick's statement by saying, "because of course you can", this statement is what implies that Gatsby is nostalgic and delusional, despite evidence to the contrary proving the Gatsby's statement. as incorrect. Furthermore, even though Daisy was married to Tom, Gatsby was still obsessed with the idea of ​​marrying Daisy, as is shown in chapter 5 where having... middle of paper... nostalgia for the past, is useless and useless. it will only lead to bad future events, to the point that there is no future for the nostalgic. In conclusion, we have learned that nostalgia is what prevents the individual from reaching the future and any further desire for the future. past, will lead to the end of the possibility of a future for the individual. Gatsby, being an example in the story, was deliriously full of nostalgia and as a result met the tragic fate he met at the end of chapter 8, with his death after being shot by George Wilson. Overall, the lesson that Fitzgerald taught his readers is that we must leave the past behind and move forward into the future, otherwise the past will drag us along with it and the future will no longer exist for us, to a tragic end . it is the result of the delusional continuing to be nostalgic.
