Reality remains veiled; nobody knows it, and everything is an interpretation. We are “blind to the world”; we are not looking outside, but rather inside our own heads. We are reading from the brain, watching a film that runs on our cortex. We are prisoners of an inner world, of a machine that produces a virtual reality. So it ends that the senses—our only means of contact with the external world—keep us separated from it through representations that are not real.
