But don't you do the same with your model? Presupposing it?
No, you just consistently ignore the evidence despite the fact I have lost count of how many times I've explained it to you. Exactly as you have in this thread, you forget anything you're told five seconds after and whine that a question wasn't answered. How are you not just a tremendous waste of time? You're incapable of learning a thing.
When explaining what is contained within a model, it is necessary to presuppose it: else how are you to explain it? When trying to poke holes in an explanation, you cannot simply presuppose your model and thus presuppose that the explanation is false, you have to mount an actual argument.
When trying to compare models and how one is better than another, then presupposition should be avoided.
Do you understand the difference between those two situations? the discussion in this thread is the former kind.
Let's see how long it takes for you to completely forget this basic fact of logic yet again.
