Let's describe a world with four people in it. Alice, Bob, Cecil, Dan. In addition, there is You in this world. Now consider two distinct scenarios:

Scenario 1: You are Alice. This means that you have access to Alice's thoughts, feelings, perception, and can see, hear, feel through her body.
Scenario 2: You are Bob. This means that you have access to Bob's experience, etc.
The question is, what is the difference between the two scenarios?

On the one hand, there is a huge difference, since Your perception of the world is not the same. In fact, Your entire experience is completely different. Since You are part of the world, that means there is a difference in the two scenarios, which concerns Your experience.

On the other hand, there is absolutely no difference between the two scenarios. There are still only four people in the world, and each of them have their own respective experiences, thoughts, feelings and perceptions. Alice is still Alice, just like Bob is still Bob, in both cases.

Therefore, we identified a difference in the world, which is how You experience it, yet at the same time we have shown that this You we are talking about is actually nothing. Does that mean that the world is fundamentally self-contradictory?
