I believe that the brain has similarities to a computer. And I believe that the brain has belief systems in it, similar to a computer program. And I believe that some of those programs and belief systems can be modified or replaced. We can change errors in our belief system. And obviously, if our belief system changes, our perception of the world will change. If I change my belief system to something more accurate, and I am part of the world, then the world did actually change. So, in that sense, the world did actually change. It’s one of those things that is a little tricky to understand.
