Nonsense! Logistic formal systems are entirely about symbol manipulation
and avoid admitting mental abstraction, they're wholly physical although
some of them are contingent on the availability of infinitely large
amounts of paper and ink. Try telling me about a theorem with no
symbols, not even in brain structure, neither spread over time nor space!
The place people get muddled up is thinking that ontological assignments
are part of the system.
That's why they think systems can be inconsistent instead of merely
indiscriminate. They think one of the objects of the system is logical
negation even when it isn't AND they think that the fact they think it
also makes it so for everyone. Probably because they conceive of a
logistic system via embedding in another system, formal or informal, and
are unable to do it algebraically so they "define" one of the symbols to
be negation instead of inferring it from the symbol's properties.
The reality is the system they think inconsistent is either informal
(and therefore not logistic) or it merely doesn't contain any
propositions distinct from its theorems.
