I greatly appreciate the care with which Professor Falk read my essay and the time he spent in writing a response to it. His comments have helped to sharpen and illuminate the differences between us and he has clarified for me some of the points he makes in A Study of Future Worlds. I will reply just briefly to some of the comments that Professor Falk makes in his response.

1. As Professor Falk indicates, some of the major differences between us are empirical —he would say “partly”; I would say “largely.” That is, we differ on the existence and significance of rising political forces or counterelites and the likely growth and future impact that these forces will have.
