Scott Fitzgerald's themes of illusion relate to societal norms and uses the rhetorical trope of ethos to describe his message to readers. From this passage, one could infer that F. Scott Fitzgerald's main message is that sometimes what we think will make us happiest is not always the case. Thanks to Dexter Green's ambition to do whatever it takes to convince Judy Jones and his downfall in the United States, it proves that the American dream can be achieved. However, even after achieving the American dream, not everything will always be perfect, and sometimes some things that we think will complete us are not. Towards the end of the passage, Fitzgerald lays out the whole point of Dexter's perception of Judy Jones as nothing more than an illusion through the comparison between her and the old house, which was once bright and bright.
