If reality is so loosely weaved, leave your house by the second floor window because you strongly believe you will be able to leave the house that way and then see if your assumption holds up.
From your perspective, I might be dead. From my perspective, though, the universe itself would have ceased to exist along with me. That's exactly what I mean. Does reality exist for me separately from my perception of it? Rather, it seems like it's constructed by my perception of it.
If the universe does not exist apart from you, what accounts for discovery and surprise? Wouldn't you have to argue that when you are surprised, it's really some part of your mind revealing itself to some other part of your mind? Also, it seems a bit implausible that a universe constructed by the mind (or "perception") would be so precise. When I dream, the laws of physics are certainly not precise. But when I am waking, they are. The only way this could be internally generated is if all the laws of physics were somehow inside of me, and I brought them forward by some ulterior process akin to the doctrine of recollection.
