To quote from the sci-fi classic, The Illuminatus Trilogy by Robert Shea and Robert Anton Wilson:
It is now theoretically possible to link the human nervous system into a radio network so that, micro-miniaturized receivers being implanted in people's brains, the messages coming out of these radios would be indistinguishable to the subjects from the voice of their own thoughts. One central transmitter, located in the nation's capital, could broadcast all day long what the authorities wanted the people to believe. The average man on the receiving end of these broadcasts would not even know he was a robot; he would think it was his own voice he was listening to. The average woman could be treated similarly.So what do you think? Would a lack of inhibitions be the end of civilization as we know it, or would it create a life free of stress and anxiety, full of new and exciting works of art and innovations that the superego had suppressed?
It is ironic that people will find such a concept both shocking and frightening. Like Orwell's 1984, this is not a fantasy of the future but a parable of the present. Every citizen in every authoritarian society already has such a "radio" built into his or her brain. This radio is the little voice that asks, each time a desire is formed, "Is it safe? Will my wife (my husband/my boss/my church/my community) approve? Will people ridicule and mock me? Will the police come and arrest me?" This little voice the Freudians call "The Superego," with Freud himself vividly characterized as "the ego's harsh master."
