The Matrix
There are also references to Simulacra and Simulation, a very modern philosophy book by Jean Baudrillard. Baudrillard says that in the modern world, copies of copies are made. "The Real" is gone because people do not know what the first things were. For example, a modern person who eats a chicken did not kill the chicken. That person does not know what a real chicken is. The chicken meat is false because the person did not kill the chicken. The person's reality is the chicken meat.
