Do we live within a Matrix-like simulation?
We cannot really know. Even if a Morpheus comes to rescue us, we cannot know that that world is the real one.
And we do know that our perception of the world is filtered through our very limited senses, is pieced together by our brain, and is strongly colored by and filtered through our conscious and less conscious assumptions about ourselves and the world. In a very real sense, we are – collectively and individually – living within our own virtual simulation.
In short, we cannot trust any of the content of our experience. We cannot trust our senses. We cannot trust our interpretations, thoughts, and views about it.
So is there anything we can know for certain? Yes, fortunately. We can trust what we are. We can trust what the content of our experience happens within and as.
We can have fun with how we phrase this:
The content of our experience is unreliable and cannot be trusted. We can only trust what we are.
We can also say that who we are, and the world this character lives within, is notoriously unreliable and cannot be trusted. We can only trust what we are.
