I'll draw two objections to this method.
(1) It is silent on some questions of mathematical interest deeming
them as meta-mathematical.
(2) There are subjects of mathematical interest that are not
The first objection is concerned with questions like is ZFC
consistent? or is ZFC true? etc...
More appropriately put with the context of this method, questions
about justification of the primary rules of the game. Clearly this
method is not concerned with any prior specifications on choice of the
rules of the game, it opens the door wide for ALL such games, and
considers all Analytic output of those games to be mathematical
despite the metaphysical nature of the game or the justification drawn
for its premises, what matters to this method is just the fellowship
of the results from the premises whatever those premises are. But to
many mathematicians the nature of the game is itself important and
justifications around it does matter. The statement that for example:
Con(ZFC) ->Con(Z) although absolutely true analytically yet it would
turn to be a trivial result if ZFC was not consistent, and ignoring
justification for the antecedent in those statements might lead us to
be involved with trivialities.
The answer to this question lies in understanding that not every
question raised within the discourse of some discipline qualifies it
as part of that discipline. For example I need a microscope to
diagnose some infections, now a lens is a part of that microscope but
the detailed manufacture of that lens and questions raised about it is
not part of the clinical medical practice. The details of manufacture
of a drug is not part of internal medicine, yet the internist is
involved primarily in treatment of diseases using drugs. It is the
same matter here mathematics uses rule driven fictional realms to
harvest analytic facts raised within them, the fictional realm itself
and the justification for selecting its rules is not part of
mathematics. What the mathematician demands of course practically
speaking is for the meta-mathematician to tell him that the so and so
system have strong justification, so that he uses them without being
just wasting time with trivialities much like what the physician
demands from the pharmacist or the drug manufacturing company, that
there are evidence that the drug works.
The other objections is that some theories have been of interest to
some mathematicians like ZFC for example, and this being a logically
driven fictional game is too far from being approximative of reality.
It is generally thought that approximating reality would require no
more strength than third order arithmetic which is way weaker than the
vastly strong ZFC, but still ZFC received mathematical interest.
The answer is that ZFC although speaks about a structure that is
vastly huge in comparison to the real world, however still all of its
primitives and premises are to some extent clear and naturally
mimicking albeit leading to strong ideal worlds way beyond the natural
ones. Still the motivation behind such strong theories is that they
can shorten proofs about the fractions of them that are naturally
mimicking, so although some theories in third order arithmetic can be
proved taking say very long proofs by just using third order
arithmetic apparatus, yet using the stronger theory might prove them
in much shorter way! and in that manner they are practical and useful,
so they are worth studying. So those strong systems are hoped to
provide easier and shorter answers to the proximal virtual parts of
them, thus they can be understood as approximating also or more
appropriately put being useful to facilitate such approximations.
However still that objection lies against "interesting mathematics"
and not against the definition given here for "mathematics" in general
which is not needed to be mingled into such matters.
Actually both objections are to be raised against "interesting
mathematics" rather than to the general definition of mathematics
given here, since the later will cover all those cases whether
interesting or not. Of course interesting mathematics have some meta-
mathematical component in directing study of mathematical issues, but
the mathematics harvested at the end are just those that are devoid of
those assumptions, they are just the *fellowship* of results from
those assumptions which has nothing to do with the justification given
to those assumptions per se.
