Strange Loop and Fourth Way

I've had some additional promptings from my subconscious since the last entry on Douglas Hofstadter. There are added key names that I would expect to find in a study of feedback as the structure of human identity: Gurdjieff, Elmer Green.

Elmer Green is a western scientist and the pioneer of clinical biofeedback.

George Ivanovitch Gurdjieff, teacher of the Fourth Way, showed us how to use conscious feedback to come to real life.

Why would Hofstadter leave these names and other associated resources out of his investigation? Is he trying to present a view point based only on his own technical research, yet he lists many others in his bibliography, Rudy Rucker, Dennet, Dawkins, Ambrose Bierce?

Perhaps he is trying to present a 'Western' viewpoint, but then why would he leave out Elmer Green?

I suspect that his work is more autobiographical than it is a serious argument. I will read further and find out more about what he has to say.
