new reality tunnels by removing old filters and replacing them with new ones, with new perspectives on reality—at will. This is attempted through various processes of deprogramming using neuro-linguistic programming, cybernetics, hypnosis, biofeedback devices, meditation, controlled use of hallucinogens, and forcibly acting out other reality tunnels. Thus, it is believed one's reality tunnel can be widened to take full advantage of human potential and experience reality on more positive levels. Robert Anton Wilson's Prometheus Rising is (among other things) a guidebook to the exploration of various reality tunnels. Similar ideas We don't see things as they are; we see them as we are. – Anaïs Nin Harvard sociologist Talcott Parsons used the word gloss to describe how the mind perceives reality. We are taught, he theorised, how to "put the world together" by others who subscribe to a consensus reality. "The curious world of Talcott Parsons was where society was a system, interactive subsystems adhering to a certain set of unwritten rules." The meme is another source of gloss; it is "transmitted from one mind to another through speech, gestures, rituals, or other imitable phenomena." Because we're social creatures, there are reasons for us to adopt some social currencies. In line with Kantian thought, as well as the work of Norwood Russell Hanson, studies have indeed shown that our brains "filter" the data coming from our senses. This "filtering" is largely unconscious and may be influenced—more-or-less in many ways, in societies and in individuals—by biology, cultural constructs including education and language (such as memes), life experiences, preferences and mental state, belief systems (e.g. world view, the stock market), momentary needs, pathology, etc. An everyday example of such filtering is our ability to follow a conversation, or read, without being distracted by surrounding conversations, once called the cocktail party effect. In his 1986 book Waking Up, Charles Tart—an American psychologist and parapsychologist known for his psychological work on the nature of consciousness—introduced the phrase "consensus trance" to the lexicon. Tart likened normal waking consciousness to hypnotic trance. He discussed how each of us is from birth inducted to the trance of the society around us. Tart noted both similarities and differences between hypnotic trance induction and consensus trance induction. (See G. I. Gurdjieff). Some disciplines—Zen for example, and monastic schools such as Sufism—seek to overcome such conditioned realities by returning to less thoughtful and channeled states of mind. Similarly, the philosophy
