Just catching up on this thread, I find it very interesting reading the various perspectives on what “mind control” is.
One thing that keeps occurring to me is how we are in a sense all unaware of the assumptions on which our perception of truth and reality are built. I am a Bible believing Christian and I interpret my experience of the world through that understanding. I am sure that in the eyes of some, that would brand me as a “mind controlled religious zealot”.
Just before you do, consider what mind control really is - a set of firm views about the nature of things through which we interpret the universe and our place in it.
Are not empiricism, skepticism, agnosticism and atheism also clear systems of mind control? Not sure? Watch Richard Dawkins some time...
