Isn’t it crazy that your whole concept of everything is in the brain, even your concept of your body being in a particular location, or of space between objects, or of temperature? And it’s impossible to escape the brain.
I’m looking around the room, but none of it is actually external. My concept of space, of that desk, that picture, that lamp, are all inside me brain. The whole world as I know it is inside my head. My hands even. I’m looking at them right now. They appear to be outside in the world, but really my concept of them is a projection inside my brain.
The world as it is objectively is impossible to comprehend, because there aren’t enough senses to perceive it, and pay attention to every part of it. I imagine reality to be an infinite number of particles and forces (some of which no human being can ever know due to lack of a sense that can pick up on them) without any sense of sense whatsoever. No light as we think of it, or color, or heat, or any other quality, since those are qualities and humans can only think in terms of qualities.
