This thread has been rolling around in my head. Finally it struck me that like religion, permaculture will have different factions, like the split in religions.You can follow the spilts in Christianity and Islam down the years. They believe basically the same thing but have variants. It seems that when an idea/belief/philosophy etc gets a critical mass of followers, splits appear espousing emphasis on different aspects of the manual with different interpretations(bible/planning scheme/design principles). Maybe it is the nature of the beast. Reminds me a bit of that scene in "Life of Brian" (not of the worm variety), follow the sandal, no follow the sacred gourd...........In the end, you know what is right and wrong according to your own conscience. If you deliberately hurt others you are only hurting yourself. All is one.
