My external sensations are no less private to myself than are my thoughts or my feelings. In either case my experience falls within my own circle, a circle closed on the outside; and, with all its elements alike, every sphere is opaque to the others which surround it. . . . In brief, regarded as an existence which appears in a soul, the whole world for each is peculiar and private to that soul.
A person has all sorts of lags built into him Kesey is saying. Once the most basic is the sensory lag the lag between the time your senses receive something and you are able to react. One-thirtieth of a second is the time it takes if you are the most alert person alive and most people are a lot slower than that.... You can't go any faster than that... We are all doomed to spend the rest of our lives watching a movies of our lives - we are always acting on what has just finished happening. It happened at least 1 30th of a second ago. We think we are in the present but we aren't. The present we know is only a movies of the past and we will really never be able to control the present through ordinary means.
