A person has all sorts of lags built into him, Kesey is saying. One, 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. Now Cassady is right up against that 1/30th of a second barrier. He is going as fast as a human can go, but even he can't overcome it. He is a living example of how close you can come, but it can't be done. You can't go any faster than that. You can't through sheer speed overcome the lag. We are all of us doomed to spend the rest of our lives watching a movie 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 movie of the past, and we will really never be able to control the present through ordinary means. That lag has to be overcome some other way, through some kind of total breakthrough.
