About the Series

Ideas in Progress is a commercially published series of working papers dealing with alternatives to industrial society. Authors are invited to submit short monographs of work in progress of interest not only to their colleagues but also to the general public. The series fosters direct contact between the author and the reader. It provides the author with the opportunity to give wide circulation to his draft while he is still developing an idea. It offers the reader an opportunity to participate critically in shaping his idea before it has taken on a definite form.
Future editions of a paper may include the author’s revisions and critical reactions from the public. Readers are invited to write directly to the author of the present volume at the following address:
