The control machine is simply the machinery — police, education, etc. — used by a group in power to keep itself in power and extend its power. For example, in a hunting society, which can only number about thirty, there's nothing that could be called a control machine in operation. They must function effectively as a hunting party in order to survive, so leadership is casual and you have no control machine. Now as soon as you get an agricultural society, particularly in rich land, you will tend to get inequality. That is, the advantage of slave labor then becomes apparent and you may have, as with the Mayans and Egyptians, workers and priests — in other words, satisfaction, repressions, and you have a control machine. As I said, the ancient Mayans had almost a model control machine through which about one or two percent of the population controlled the others, without police, without heavy weapons. The workers all had such weapons as were available, stone axes, spears, etc. So it was pure psychological control.
— William S. Burroughs
Control, a common theme that threads throughout Burroughs' work. He even felt that love was a form of viral madness, meant to control the individual. Personally I don't think he was entirely wrong on that front.
