The second error is a simple flaw in your logic: human brains can calculate all computable functions (in theory), therefore the brain *is* a computer (equivalent to a Turing-machine).
Copeland calls this the equivalence fallacy. You cite his paper, but apparently have not read or digested that part of it?
The theory of computation is explicitly a theory of what *humans* can do by rote (as you write in the paper), so it is hardly a surprise that brains can do effective ...

@tyrell_turing@fediscience.org ... computation. What you can't see (from within your computational small-world worldview) is that this is by far not all that brains do, nor did brains evolve to do this (most animal brains don't engage in this kind of activity at all, in fact). The logic error: for the brain to be literally a computer, it would have to do nothing but compute (in the Turing sense). As I said above, you simply assume that this is the case, bcs you assume that the whole world is computable ...
