That is what is relative. If we are discussing as share inter-subjective experience of the simulated things in a simulated universe or not.
Logical applies to cognition. Not things in themselves, but your experiences in your mind.
Stop confusing logic and metaphysics/ontology.
Again, I'm not confusing anything. Please stop telling me what to do when you don't actually know what you're talking about. You don't have room to lecture others on logic when you're literally arguing against the law of non-contradiction. Whether the pen exists only in my mind, or in reality, it remains the case that it can't be both longer than 3 inches and not longer than 3 inches, in the same way and at the same time.
