Then computationalism is false. But what are your
evidence for a *primary* physical universe. That is an
axiom by Aristotle, and I believe animals are hard-wired
to make some extrapolation here (for not doubting the
prey and the predators), but there are no scientific
evidence for a *primary* physical object.
There is no scientific evidence for a universal dovetailer
either.
We don't need evidence here. The existence of the universal
dovetailer, and of all its finite pieces of executions is
already a theorem of very elementary arithmetic. Those things
exist in the same sense that prime number exist.
Which is merely as thought patterns in the brains of physical beings.
A large (and familiar on this list) metaphysical leap, which fails to
explain how two cultures can discover the same maths, or indeed why
maths "kicks back" at all.
For the same reason that two cultures experience the same physics. Maths
doesn't kick back -- only physical objects do that.
