I bought and read Synergetics when it was first published in 1971 and apparently was one of the few who actually bought and read Synergetics Vol 2. It’s no coincidence that used versions of Synergetics go for $25 whereas Vol 2 cost me $125. This is because, for many people Synergetics was difficult not only because it had no index, but many of the concepts seemed to be quite half-baked. Many people just didn’t bother with Vol 2. It was only later, after I had both volumes on hand, that I realized that Fuller’s scenarios ran through both volumes, starting in Synergetics and finishing in Synergetics Vol 2.
One of the things which helped to alleviate this problem was the project by E. J. Applewhite to put this entire work (Synergetics) online, fully noted and searchable. It is wonderful research tool and Mr. Applewhite is to be thanked for the effort.
Fuller only touches on the Spiritual while fully allowing for it. He is mainly focused on how things work. How trees and kites and bicycle wheels actually did their jobs in the most efficient and economical ways and did minimum damage to the environment. A way for all of humanity to realize its full potential and to realize that we must all come up as a whole not as parts with some rushing above others.
