Nowadays there are multiple logics. Some are just mathematical playthings,
but many are used in the real world. (The two I somewhat know are fuzzy
logic, used in many problems like thermostats, to represent predicates
like "hot" which has varying degrees of truth; and quantum logic, used
in subatomic physics.)

Speaking of non-classical logics
<https://en.wikipedia.org/wiki/Non-classical_logic>, I heard RYBS
discuss bein hashemashos one year in a yarchei kallah shiur in which
he asserted that halakhah is a multivalent logic (one that allows
for values other than true vs false). Frankly I think he meant that
halakhah uses a logic that has no law of contradiction. Because RYBS's
topic was how bein hashemashos is actually both days at once. This
explains why an esrog used one day is assur BHS because it's the same day
and then assur the next day because it was also BHS -- the start of
that day.

But the notion of noone special logic makes the Rambam's idea that logic
is part of Truth and thus of His Essence much harder to support. You would
have to go meta, and speak of the usability of various logics in general.
