 I think a lot of people have a hard time letting go of this idea that mathematics is just ultimately describing some relationships between stuff that's fundamentally non-mathematical. If you're in a computer game, there is no actual stuff in Pac-Man, right? It's the entire nature of Pac-Woman or these little things you gobble up or the monsters or just relationships between abstract things that have no intrinsic properties at all. There's, actual stuff there. And in the same way, I think this is what we've learned about our physical world. It's the relationships that really, really matter between things in the world and that's ultimately all there is. The entities themselves have no properties except the relationships that they have. That's not that different in some sense from our thoughts and the subjective experiences. They feel a little bit more ethereal than a book or an apple. But it's the relationship between the different pieces of information that give it the texture and subjective properties that we're so fond of. And the stimuli that comes in from the exterior and throughout the entirety of our path of life. There's no mind that's exactly yours. We're receiving the exact same stimuli. And also if you think you ask yourself why is it that the sound subjective feels very different from say the experience of the color red. It's not anything to do with the outside world. It's actually represented in the brain in very similar ways. Electrical firings of neurons that you could sort of tell the difference between them and the microscope. The reason one feels like a sound and one feels like a visual experience just has to do with its relation with other pieces of information when it's in your brain. And you can have all that experience even when you're not looking or hearing the world at all. When you're sleeping and dreaming, right? It still feels the same.
