Why are you jumping from some symbols being rearranged on a Turing machine to assuming unknown and arbitrarily complex instantations loosely resembling said symbols? Of course a brain ‘imagining’ something exists on level 4, but why credit any particular form of imagination as being coherent and also greater than mathematics? If you imagine a square triangle, how is that a refutation of Tegmark level 4, rather than, say, evidence that a brain can emit two words in succession which don’t mean anything?
So basically, that’s all that your point boils down to? “never mind the failure of millennia of imagination-based reasoning and the striking success of mathematical reasoning in those millennia, I’m just going to make imagination the arbiter of metaphysical possibility even if that means embracing contradictions and other such nonsense”? That’s pretty lame.

Why privilege TL4 over your imagination?

So you refused to understand my original point and resorted to misrepresenting, strawmanning and eventually insults? Nice. Tapping out.
