Watching the movie "The Matrix", it is natural to wonder whether the world we live in is real or not. Neo, the hero, learns that the world he lives in is not real thanks to Morpheus. In the future world, the computer rules humans, who in turn are born to grow in an incubator. Furthermore, human brain nerves are connected to computer networks, which means that humans cannot help but live in another incubator until they die, even if they cannot recognize that they live in the incubator. Plato's allegory of the cave is analogous to the plot of "The Matrix". People live in a cave, watching their shadows reflected on the cave wall. They never realize they are in a cave. Plato's allegory of the cave presupposes key words that drive the story such as chained prisoners, a puppet trainer, and a prisoner trying to find a light. These terms are comparable to John Updike's characters in his A&P novel and guide readers to the implications between the lines. Updike A&P's novel seems to deal with the theme that love sucks, but with the application of Plato's allegory, another hidden theme in his novel is revealed. Now, those key words from Plato and the characters from Updike's A&P will be compared and analyzed here to delve deeper into what the author implies in his novel. The prisoners in Plato's cave correspond to all those characters in the novel, who try to settle down in reality. The prisoners of the cave allegory stare motionless ahead, and continue to live looking at their own shadow, which is the reflection of a torch lit behind them. Furthermore, they believe that shadows are reality. Without knowing it they are imprisoned in a cave, they just live. Occasionally, they see a light coming from the outside world, but they find themselves... in the middle of the card... in a new atmosphere without restrictions. Plato's allegory is applicable to A&P drawing a theme. The story of a foolish boy, who gives up everything for love when he knows that his decision could prove to be a severe blow for the rest of his life, implies that we should move to a new world where we can grow further by breaking the structures of old thoughts and values ​​present in society according to which rules are rooted in everything. Furthermore, like the claim that those who leave the cave for an ideal world outside and become enlightened should awaken those who remain in the cave from their ignorance and cause them to see that there is light outside the cave, I suppose that the novel probably suggests that we should break the old values ​​and ways of thinking, move towards a new world and guide those who still hide in the dark cave of ignorance as guiding lights.
