I’d like to add a little something to go with teaching of “ideas”. (perhaps more than a comment),

Ralph Waldo Emerson wrote in his essay Nature:

“Whenever a true theory appears,
it will be its own evidence.
Its test is,
that is will explain all phenomena.”

Here is the thing – what Moshe Feldenkrais brought to the table in my opinion, and I am sure others would agree, is big. It is a part of this “true theory that can explain a lot of phenomena”, because if it wasn’t, it wouldn’t be able to be discussed across multiple disciplines and have effect on a such a wide variety of “stuff” – in essence it can explain a lot, maybe not all, but a lot of phenomena.

We are running a risk if we keep it under a blanket of protection, trademarking and copyright, because then this makes it look like a “product”. A product comes and go’s and doesn’t stand the test of time. True theory and Big ideas that make big differences in ALL aspects of human nature stand the test of time, ARE their own evidence, are potent, and certainly don’t need protection.

Are people seriously teaching AY word per word in the same order as on the transcripts? Would Moshe even teach his AY lessons word for word? From the Feldy history I’ve learned over the years, it took him numerous times until he was satisfied enough to record his AY lessons, and then, I am sure he changed them again and again. How would he teach now? His teaching even changed between San Francisco and Amherst trainings, did it not?

So is the copyright of AY and transcripts even the issue? Are they not a part of the history of the work? Is history copyright’able’ and trademark’able”?
Should it be?

Those that truly know this deep in their own nature (the importance spreading important ideas) will do whatever is necessary to teach and really do the work – regardless of being obedient to any “law”.
