Reality doesn't exist; at least not in the way that we usually think of it. Dr. Jorge Martins de Oliveira writes,
“Our perception does not identify the outside world as it really is, but the way that we are allowed to recognize it, as a consequence of transformations performed by our senses. We experience electromagnetic waves, not as waves, but as images and colors. We experience vibrating objects, not as vibrations, but as sounds. We experience chemical compounds dissolved in air or water, not as chemicals, but as specific smells and tastes. Colors, sounds, smells and tastes are products of our minds, built from sensory experiences. They do not exist, as such, outside our brain. Actually, the universe is colorless, odorless, insipid and silent."Dr. Oliveira isn't a touchy-feely philosopher, a halfwit existentialist or the delusional leader of a religious cult. He's the Director of the Department of Neurosciences at an institute in Rio de Janeiro. According to Oliveira, each of us lives in a private world of our own perceptions. Speaking of this perceptual reality he writes,
"Although you and I share the same biological architecture and function, perhaps what I perceive as a distinct color and smell is not exactly equal to the color and smell you perceive. We may give the same name to similar perceptions, but we cannot know how they relate to the reality of the outside world. Perhaps we never will."
