The Way of Zen

by Alan W. Watts

The proper adjustment of a feed-back system is always a complex mechanical problem. For the original machine, say, the furnace, is adjusted by the feed-back system, but this system in turn needs adjustment. Therefore to make a mechanical system more and more automatic will require the use of a series of feed-back systems–a second to correct the first, a third to correct the second, and so on. But there are obvious limits to such a series, for beyond a certain point the mechanism will be “frustrated” by its own complexity. For example, it might take so long for the information to pass through the series of control systems that it would arrive at the original machine too late to be useful. Similarly, when human beings think too carefully and minutely about an action to be taken, they cannot make up their minds in time to act. In other words, one cannot correct one’s means of self-correction indefinitely. There must soon be a source of information at the end of the line which is the final authority. Failure to trust its authority will make it impossible to act, and the system will be paralyzed.
