That's just syllogism, and makes for constructivism
since any sort stipulation, like an axiom, is unfounded.

The "axiomless natural deduction" to arrive at "axiomless
geometry" and "axiomless arithmetic" is a usual notion that
mathematical platonists have, though these days sometimes
they call themselves structural realists to not concern
dear old Bertrand, then though logicist positivists take
that label without fulfilling its definition.


Syllogism is subject ordering, and Aristotle reads every
syllogism its statements in every order, for example to
detect cycles and disambiguate them, which otherwise a
linear reader will fail to detect.


The "principle of _thorough_ reason" is more than the
"principle of 'sufficient' reason", then that in a
wider account of a wider, fuller dialectic, what's
sound, thorough, fulfilling, and fair.


Mentioning something like Prawitz' "inversion principle"
and about both the restriction _and_ the recovery, and
more than Russell's mere "isolation in significance and
significance in isolation", means that restricting (ignoring)
the resolution of any and all paradoxes leaves the door ajar
just like quasi-modal logic and principle of explosion.


So, maybe readers and researchers in foundations should start
with outlining the requirements and desiderata of a theory
that's constant, consistent, complete, and concrete,
and see how axiomless natural deduction fulfills that
with a comprehensive yet paradox-free account, and
that's the usual account since antiquity and even since
before recorded times, then it's called "mathematical platonism",
since issues of the human condition itself are subjective,
and whether Thoth or Hermes Trismagistus has an ankh for reason
or spiral for infinity, in at least one account there's both.

Thoth -> thought
Logos -> logic
Ma'at -> math


Aristotle won't be made a fool, and more than merely
half-Aristotleans have always both prior and posterior accounts.
