We can reframe any problem into a different problem with different assumptions and different constraints.
We can do so with existence. U can deduct that I never existed and that U never existed. And that whatever we are perceiving and feeling right now isn’t existence, but something else which we haven’t came up with a name for yet.
I suppose some of this argument is entirely semantics. I do not mean existence in the same sense that U mean existence.
So let me reframe the concept in a way that is different from Urs (or so I would think - perhaps it is the same). Existing is enacting cause and effect relationships that sometimes have the intended consequences and other times do not. But what is the hidden device that aligns intention and effect? What is intention and what is effect?
I cannot answer these questions; can U? I feel the inability to answer them is a bit like not existing.
