is talking about when he mentions Aristotelism. It relates to a
question of reductionism and explaination. "Is physics the most
fundamental science, or can it be explained and derived from
something at a lower layer?"

Is ??? really the floor or does ??? need an explanation too? If
not and there are only finitely many layers to your pyramid then I
think it more likely that physics =???, physics is the explanatory
floor and mathematics is just the best language minds can use to
describe physics.
If mathematics was a language, there would not be any open problem in
pure mathematics.
Moreover, since Gödel, we know that once you agree on classical (with
excluded-middle) arithmetic, the arithmetical reality (or the set of
all arithmetical true sentences, or the set of true sentences of any
sigma_1 complete theory) is not completely describable by any
effective theory.
Then UDA shows that if you take physics as the explanatory floor, you
might be able to explain consciousness (with a physical form of
computationalism), but you will not been able to explain the first
person stability of that consciousness, which can only be explained by
(re)-defining physics as a measure on *all* computations going through
the relative states (or you will need the magic ability of some God
(Primary Matter or any other Magician) to do the selection.
