Everything that is real is a lie except your thoughts. If someone approached you with this statement, you would assume that they are crazy and try to convince them that you are real and that the world is real. When you start trying to prove reality, you start to ask yourself: under what circumstances do we understand reality? When we recognize what we believe to be reality, we form conclusions and assurances about our own existence and the existence of everything around us. Since our existence is ensured through our perception of reality, we believe that we are part of an existing real world. The existence of the real world is based on belief and cannot be proven. The existence of the real world originates from our brain. Reality depends on our perception, our experiences, our senses and our reasoning. Descartes ensured his existence through the belief of “Cogito, ergo sum” which translates to “I think therefore I am” (Popkin & Stroll 198). To question one's existence one must exist, non-existence cannot question itself. I know my mind exists because I am here to question its existence. To bring this idea to life, imagine a house and you are building a house on the land you see. The house is built of wood, metal and earth on the ground. Does the house exist because of the materials used to build it or because your mind tells you it exists? Based on Descartes, there are no such things as wood or metal in reality because the only real thing is the mind itself and the house you build is an invention of your mind compared to what you perceive as real, better known as an illusion . Therefore everything we feel is an illusion and everything outside the mind is uncertain of existence. Furthermore this leads to...middle of paper......and the situation that triggers the emotion of hate, anger, sadness. When a person begins to connect negative experiences to positive emotions, they begin to love themselves more and not fear their reality. By loving themselves they create a loving reality. In the film, after Amanda redirects her neural network, she begins to heal. She is able to deal with her husband's betrayal which caused a lot of pain and hatred in her being. As he heals, he gains control of his reality. Works Cited J. Perry & M. Bratman, Introduction to Philosophy, third edition, Oxford University Press, 1999 (hereinafter P&B).R. Popkin & A.
